Darwin’s Theorem


Science, religion, evolution, romance, action, siphonophors!

Darwin’s Theorem is a story about stories(the working title for a long time was “Metastory”) that’s also a mystery, a romance, an adventure, and various other things besides. Not quite science fiction, excessively didactic… think of it as “Dan Brown meets ‘Origin of Species’.”

If you like to see plot, action and strong characters deployed in the pursuit of big, speculative ideas, you should check it out!

Islamism is Stupid

In the past few days Islamist nutjobs have killed two Canadians. Why they are doing so is pretty clear: they are stupid.

It is stupid to attempt to intimidate Canadians by killing a few of us.

It is stupid to think that attacking innocent soldiers going about their lawful duty will result in anything other than what it always results in: solidarity amongst the vast majority of people who are on the side of law, democracy, diversity and dialog as a means of solving our problems–that is, things that actually work–against those who think mouthing arrogant, stupid, slogans about the infinite power of their god does anything other than show what a bunch of ignorant pricks they are.

“Our religion is true because it is true! We know it is true so it is true! We will be victorious! God is great!” is not a convincing argument. It is not an argument at all. In fact, it translates as, “I am stupid! I am very stupid! You would not believe how stupid I am! Soooo stupid!”

Religion–if taken seriously–is a mildly harmful delusion in the private sphere, which leads to a litany of petty miseries as the payment it demands in return for the comfort it offers its adherents. But the costs of private, personal religion are borne almost exclusively by the poor souls who are engaged in it.

Public, political religion, on the other hand, is a stupid obsession that endangers everyone.

We know this, because we have been here before.

Canada, via Great Britain and France, is a product of religious wars. Islamists don’t seem to be able to grasp–because they are stupid–that we did not get to our current state of secular paradise by being weak, we got here by being smart. It only took us a few hundred years, but we finally noticed that religion and politics, while both somewhat unsavory enterprises on their own, when mixed together generate a toxic miasma that makes chemical weapons, which only destroy human bodies, look fairly benign.

Politicized religion destroys whole societies.

Between 1547 and 1745, politicized religion did its best to destroy England, and was none too kind to France, nor Germany, neither. We fought wars over it. We burned heretics and hung, drew and quartered traitors, where their “treason” was little more than their mode of Christian worship. We rarely engaged in anything so civilized as mere beheading, which was considered a kind death. We killed and we tortured and we killed some more. We engaged in terrorism and spying and proxy wars and civil wars and real wars.

And we came to realize, slowly and by degrees over the centuries: this is stupid.

God doesn’t care how, or if, we worship. God certainly doesn’t care how we run our political systems. God doesn’t care about law, or politics. God doesn’t need us to worry about other people’s behaviour. Only, perhaps, about our own, which at least has the virtue of being something we can actually do something about. You know, without killing anyone.

God is infinite. God is incomprehensible.

Now tell me again how you know exactly what God wants.

And if you answer, “Because it is written in our holy book!” what I and anyone else with two brain cells to rub together will hear is, “I am stupid!”

And if you answer, “I will kill you if you disagree with me!” what I and everyone else with a shred of human decency will hear is, “I am stupid and evil!”

Politicized religion is stupid.

Islamism is politicized religion.

You finish the syllogism, Socrates.

Canada is amongst the most peaceful, prosperous, happy nations on Earth. We treat women as equal to men, and allow and encourage them to partake in every opportunity our society offers to anyone. We fornicate with wild abandon while our gay friends sodomize each other happily within and without the boundaries of legally recognized marriage. We worship our gods in a diversity of ways, and some of us worship none at all and think it’s a bit sad that anyone else does, while non-religious people are looked upon as lost sheep by our religious fellow-citizens. We lionize the freedom that everyone has to join any religion and then leave it, peacefully and unmolested. We treat our Jewish citizens as the nice and law abiding people they generally are.

We violate God’s laws every day of the week and twice on Sundays.

And you know what? We prosper.

God does not strike us down, which an infinite, all-powerful God could surely do.

Anyone claiming otherwise, or claiming that God needs help or that they must do personally what God has chosen not to do is: stupid.

Your infinite, all-powerful God does not need help.

You do.

Because you’re stupid.

Anyone who genuinely believes in an infinite, all-powerful God does not believe in political Islam, or political Christianity, or any other variety of politicized religion. Only unbelievers could possibly have such a belief, because only unbelievers could possibly hold that God is so limited as to need human assistance.

It follows from this that Islamists are not only stupid: they aren’t even Islamic. Because Islam is very clear that God is infinite and all-powerful.

And since Islamists are not Muslims, yet once were, they must be apostates.

And it follows from this that it is the religious duty of Islamists to kill themselves, as this is clearly the penalty that Sharia law–which Islamists claim to hew to–dictates for the crime of apostasy.

It is not my way to wish harm on any human being, but in this case I have to say I’d like to make an exception, and encourage all Islamists in Canada and elsewhere to save us the trouble of tracking you down, watching you until you do something overtly evil, and then capturing or killing you. It would be way more efficient for you to do the job yourselves. But you’re probably too stupid to follow the logic above, so I guess there’s no real point in asking.

Finally: I am deeply grateful to moderate Muslims in Canada who have helped the RCMP and others keep track of the nutjobs in our midst. I obviously don’t share your religion–and expect many of you disapprove of my particular brand of qtheism[*]–but I recognize that you derive comfort and cultural cohesion from yours and hope that Canada continues to provide a safe and welcoming environment for all peaceful, law-abiding citizens, regardless of how wacky their personal beliefs may be.

[*] Not a typo, although I just invented the term and will expand on it at a later date.

Power Too Cheap to Meter

There has been some not-entirely-unjustified skepticism about Lockheed-Martin’s recent announcement of a novel fusion reactor configuration. This post is intended to explain why I’m hopeful about this, rather than simply dismissive.

I’m a technological optimist.

But you knew that.

Timelines, etc

I don’t believe that the LM timeline is likely to pan out, but that’s simply because I know from practical experience how hard it is to get a new technology to market. Even the iterating process will take longer and cost more than expected.

However, the ability to iterate on a design rapidly is a huge, huge benefit to technology development. The kind of massive, multi-decade project that is ITER, for example, has many fewer chances to try out new things or course-correct if an assumption or calculation doesn’t prove out in reality. Despite it’s name, ITER doesn’t actually allow for iteration.

Some people are suspicious that LM is approaching this as a closed, commercial, engineering project rather than an open, scientific one. This is a bit odd, as LM is a closed, commercial, engineering company. They appear to be seeking partners to a) lay off financial risk; b) bring in additional expertise; and c) keep fundamental secrets, secret. They may be wrong in taking this approach, but there is nothing particularly untoward about it.

Details Matter

Which leaves us with the plasma physics, but then again, what doesn’t?

There are features of the high-beta design that are promising, and they say they have stolen ideas from Bussard’s variant of the Farnsworth machine and elsewhere. None of these things on their own are capable of coming close to commercial break-even, but in combination?

Details matter.

In the aerospace museum in Ottawa there is a copy of an early Bleirot monoplane built by an Ontario farmer after seeing one in France. He didn’t get a very good look, though, and didn’t understand the importance of dynamical stability (which was one of the Wright Brothers’ bigger discoveries) so while it looks like an airplane, it doesn’t actually fly because it doesn’t have ailerons (Bleirot) or warpable wings (Wrights).

If that plane had been built first, the person who built it would be an expert in the field. Although it’s a question as to what that field would actually be. There were plenty of experts in “aviation-before-anyone-had-actually-flown” (pre-aviation? failed-aviation?) but despite Edison’s famous dictum that “we have not failed, we have merely discovered a thousand ways that do not work”, having expertise in how not to do something–while valuable–is an imperfect guide to judging how do to something, especially in the absence of details.

Clarke’s First Law is a reflection of this reality: “When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.”

Let me temper this by saying, as an expert in a few things myself, I certainly appreciate that laypeople often fail to see what is wrong with certain approaches. It is easy for non-experts to go down false trails that have already been thoroughly explored by experts. But in this case, the lead researcher, Thomas McGuire is not a neophyte. It is reasonable to assume he is aware of the landscape of failure in this field, and has avoided the known false trails.


Neither I nor anyone else who knows what they are talking about has said this is anything like a sure thing. But it’s hopeful. We used to say, “practical fusion power is thirty years in the future and always will be”. Now, I’d say the time-scale in that joke has come down to a decade, and it will likely be sometime this century that it comes down to a year. Shortly after that, “tomorrow” will finally be here.

Fear in a Time of Ebola

I’ve seen a number of people in the past few days attempting to spread fear about the possibility of Ebola “becoming airborne” and thought it worth saying a few words about that. Although I’m a physicist by education, I’ve spent a good part of the past decade working in various health disciplines, including a lot of time related to bacterial detection, and I was an adjunct in the Department of Pathology and Molecular Medicine at Queen’s for some years (mostly working on cancer genetics.) I’ve even written a speculative novel about the outer limits of evolutionary theory that turns on a new kind of pathogenic evolutionary relationship. So I’ve spent a lot of time thinking about pathogens and evolution.

The Ebola virus is an RNA virus, like the rhinoviruses that give us colds. They are about 19 kilobases long, which is small. There are plenty of human genes over 100 kilobases, and they just have to code for one lousy protein, not manage a whole life-cycle of infection and propagation.

Rhinoviruses are tuned up for “airborne” propagation, which is more properly “aerosol” propagation. Aerosols in this context are tiny droplets of (mostly) water with a diameter of less than five microns. Droplets much bigger than this have a hard time getting into the upper respiratory tract, and so don’t propagate the virus. Aerosols also are small enough to remain suspended in the air for many minutes, creating more opportunities for inhalation and therefore infection, if they contain a virus capable of aerosol propagation, which Ebola is not.

One of the (many) tricks that rhinoviruses use to get into our bodies is to bind to a specific molecule (variously known as ICAM-1 and CD54 in the charming tangle of nomenclature that is modern biochemistry). It finds this molecule on the surface of epithelial cells in the upper respiratory tract. Rhinoviruses also have a preferred temperature that is 32 C, not the 37 C of the human body’s core. This makes them well-adapted to upper respiratory infection, and nothing else. Ever caught a cold through a cut on your hand? Me neither. Being adapted to one path of infection makes rhinoviruses maladapted for others.

There is a reason for this that goes beyond the specifics of any particular virus, which is the evolutionary realities of pathogen/host relationships. Pathogens are incredibly specialized. This is true across all kinds: viruses, bacteria and parasites are all aimed and extremely narrow niches in their host’s defenses. These niches are narrow almost by definition: if they were wide, the host species would have died out.

Most parasites and pathogens are adapted to a single host species. A few rarities like rabies and influenza have more general tricks, but that is because they’ve found a biochemical flaw that is shared across species, not because they’re especially versatile. Pathogens don’t do versatile. They can’t afford to: any genetic material taken up by one function is lost to all others, and to slip through the host’s immunological armor they need all the bases they can get.

So bugs like rhinovirsuses have a whole range of specialized adaptations that allow them to get into our bodies via aerosol propagation and upper respiratory infection. Ebola does not. Nor is there anything like an easy pathway for it to adapt to aerosol infection. It would have to alter its structure to bind to an appropriate molecule on the surface of epithelial cells. It would have to adapt to operate at a much lower temperature than normal. It would have to pull off a dozen other biochemical tricks that could only be performed at the cost of giving up some other function, and therefore would most likely become much less deadly in the process.

So while it’s true that given enough time “Ebola could become airborne” it is also true that given enough time “hydrogen could become people” (supernovae are required as an intermediate step in the latter case). While not quite on the same timescale as “evolution of life as we know it” such profound changes in an infection pathway would require vast amounts of time, and over such enormous periods almost everything else poses a far greater danger to us: coronal mass ejections, giant asteroid strikes, cows, coconuts, you-name-it. An influenza pandemic is far, far more likely to kill us all than Ebola: we know this because we know that in 1918 it damned near did. The flu really is a few mutations away from a 10% mortality rate.

Physically, Ebola can be carried into the air in aerosol droplets, but it simply isn’t very good at getting into the body via the upper respiratory tract, which is what is required for a virus to pose a significant airborne transmission risk. Still, if someone with the disease were to cough on an open cut on your skin you’d be at risk, so you probably want to avoid that, which… shouldn’t be too hard?

The odds that someone reading this will die from being trampled by a cow in the next year are many orders of magnitude greater than the odds that anyone reading this will die from an airborne Ebola infection. The odds that *everyone* reading this will die from a pandemic flu in the next year are orders of magnitude higher than anyone reading this will die from an airborne Ebola infection.

So if you see someone spreading panic along the lines of “Ebola could become airborne”, feel free to ask them why they are concerned about Ebola, but not about cows, coronal mass ejections, or the flu?

What a Difference a Data-Point Makes

I just recently found out about a nice bit of work from a few years ago, involving the tracking down, digitizing and processing of Nimbus satellite images from 1964 that include the poles, so sea-ice estimates could be made.

I was a bit disappointed in the graph showing the new Arctic data in context, as it doesn’t give a sense of how far back in the past this extends our record of Arctic sea ice, so I made my own:

Effect of Nimbus 1964 Data Point on Arctic Sea Ice Minima Fits

Effect of Nimbus 1964 Data Point on Arctic Sea Ice Minima Fits

This single data point resolves a significant ambiguity in the modern record: how long as the sea-ice extent during the summer minimum been falling? You can get an OK fit to the modern data (1979-2000) with a straight line, as shown, and if you add a second-order term so the line can be curved the overall quality of the fit gets slightly worse. So are we seeing a long linear decline, or something that “turned on” sometime in the the past twenty years?

The fits to the graph shown here indicate clearly it is the latter: September sea ice in 1964 was about 6.9 million square kilometres, and if you fit with that point included up to anywhere between 1990 and 2000, you get a line that is flat. Fit the later data and you get a line that is sloped downward as shown.

There is a cautionary tale here for people who want to point to a decade or two of data and make claims about the world. Unless we have comparably good data from a lot further in the past, there is little basis for wild extrapolations. The climate is non-linear and noisy, and that means climate data must be approached with enormous caution. If they are not, there is a significant risk of making wild predictions that turn out to be completely false, which does not do your reputation any good.

How News Stories Ought to be Written

The government of Iraq is requesting American troops to defend Baghdad from ISIS attacks.

Here is information the story omits.

President George W. Bush signed a “Status-of-Forces Agreement” with the Iraqi government in 2008 that specified a December 31st 2011 final withdrawal date for all American troops from the country.

President Barack Obama slowed the withdrawal of combat troops–extending the duration of their stay by ten months–but maintained the final withdrawal date of December 31st 2011 that President Bush set.

In a major diplomatic failure, the Obama Administration failed to reach agreement with the government of Iraq on maintaining bases in the country. This failure occurred in October 2011, two months before the final withdrawal of about 39,000 American troops who remained in the country to assist and train Iraqi security forces.

All of this information is relevant to the current context, and it leaves very little room over for partisan sniping.

1) The December 2011 withdrawal date was set by President Bush and implemented on a delayed schedule by President Obama.

2) The failure of negotiations to maintain American bases in Iraq was a serious failure on the part of the Obama Administration, but you’d have to be insane to suggest that the seeds of that failure hadn’t been sown by the Bush Administration’s mismanagement of the Occupation, particularly with regard to mercenaries but also failures like Abu Ghraib. “Hi! We invaded your country, freed you from a brutal dictator, then reduced the place to armed chaos, killed and tortured your friends and neighbours, and we’d like to keep somewhere between one and four huge military bases in your country but we aren’t ‘extending the occupation’ or anything! Really!”

Unfortunately, the story in the National Post contains none of this information, which took me about five minutes to track down.

Sampling Fossils

Sometime in the late 80’s or early 90’s I read an article in Nature that argued we should expect “first discovery” dates in the sciences that involve digging up fossils to take periodic leaps backward.

The argument is compelling: because fossilization and preservation of fossils are rare processes, they sparsely sample the living population. Under these circumstances the odds of us discovering the earliest of any instance of a thing are very low.

As near as I can tell, people who work in these fields don’t read Nature, because the argument still doesn’t seem to have much currency. So I thought it would be fun to put together a simple computational example that roughly models the human population. I made most of the numbers up, but the results are nicely illustrative of the phenomenon.

Consider a simple model where the human population grows exponentially from two people–call them “Madam” and “Steve”–a million years ago to three million people 12,000 years ago (which is the best estimate for the pre-agricultural human population)

Fitting this to an exponential, this gives us an e-folding time of about 70,000 years, so the population looks like 2*exp(years/70178) with time zero being a million years ago and 12000 years ago being time 998000.

Now assume that fossil preservation is a linear ramp that starts with zero probability a million years ago and ramps up to a one-in-ten-billion chance 12000 years ago: 1E-10*years/12000

If we instantiate this as a few lines of Python and randomly sample the mean number of preserved fossils each year, we get the following code:

import math
import random

fA = 0.998E6/math.log(1.5E6)
print fA

def g(fT): # population growth
	return 2*math.exp(fT/fA)
def f(fT): # fossil preservation
	return fT*1E-10/998000
# sample from a million years ago to 12000 years ago
for nI in range(0, 998000):
	fAvg = f(nI)*g(nI) # average number of fossilized remains
	if random.random() < fAvg: # actual number
		print 1e6-nI, fAvg # date of first discovery (years past)

Running this code produces dates for the oldest discovered fossils that vary nicely around the age of the oldest know fossil for anatomically modern humans, which is about 195,000 years.

But here is the distribution of results, which is unsurprisingly broad.


The red line that peaks around 200,000 years ago is for a fossil preservation probability of one in ten billion, the green line that peaks around 300,000 years ago is for a fossil preservation probability of one in a billion. Or rather, those are fossil preservation and discovery probabilities, as a fossil that has not been discovered may as well not exist in this calculation.

It should be clear on this basis that to assert, as the Wikipedia page linked above does, that "Anatomically modern humans evolved from archaic Homo sapiens in the Middle Paleolithic, about 200,000 years ago" when the oldest known anatomically modern human fossils date from 195,000 years ago is to reject some pretty basic mathematics. However many anatomically modern humans there were to begin with, the number was bound to be small, so the odds of the earliest discovered fossil being dated to a few thousand years after the evolution of a species is very small.

That "about 200,000 years ago" should really read, "sometime before 200,000 years ago, quite likely earlier than 500,000 years ago" unless the number of modern human fossils is really very high starting 200,000 years ago. And it is not: we find the earliest anatomically modern human fossils only in a few sites dating from 75,000-130,000 years before present (Klasies River Mouth), 92,000 ybp (Qafzeh) and 90,000 ybp (Skhul). So we are genuinely dealing with a sparsely sampled population.

On this basis we can and should expect that as we search more diligently for anatomically modern human remains, we will find "surprising" leaps back into the distant past. It wouldn't shock me, based on this simplistic model, if our earliest anatomically modern ancestors were a million years old. It would, however, shock the people who work in this field, just as they were apparently shocked by the Omo remains, which took things back a mere hundred thousand years earlier than previously known.

This is a all a bit sad. As I said, I read an article about this phenomenon in Nature over twenty years ago. We should have robust models of fossil survival probabilities and discovery probabilities now, which would allow us to use the actual data to make valid Bayesian inferences about how old our earliest ancestors are likely to have been, rather than innumerate statements that claim fossils that are 195,000 years old support origin dates of less than 300,000 years old, when in fact they almost certain make far older dates much more plausible, and dates of less than 300,000 years before present very, very unlikely.

To claim otherwise is to claim either that the early human population wasn't growing much over hundreds of thousands of years, but became almost immediately high and stayed high for the rest of pre-history--which doesn't seem very plausible--or it is to claim that fossil preservation and discovery is a common process, which also doesn't seem very plausible.

Although the model presented here is exceedingly simple-minded, it significantly increases the plausibility of the proposition that early anatomically modern humans existed for much longer than would be naively inferred.

As sampling becomes less sparse--as we move more closely toward the present day--this phenomenon will become smaller, but it wouldn't shock me if our evidence for the peopling of North America turns out to underestimate the antiquity of that process, for example.

To refute the argument I'm making here requires that one create a plausible model of population growth, and fossil preservation and discovery that allows in the typical case for the date of the earliest discovered fossil to be very close to the date of earliest appearance of the fossilized species. I can't think of such a thing, but perhaps someone else can, which would be fascinating indeed.

The Institute of Evil Studies

The Institute of Evil Studies doesn’t actually exist, but it should. Philosophers and theologians have wittered on about evil for thousands of years without making any progress beyond irrelevant arguments about angels and demons and “deep” questions about whether humans are “naturally evil” or “basically good” or some such gibberish.

For all the ink–and blood–spilled in the name of philosophic and religious views of evil, they have unsurprisingly provided very little actionable insight into the primary practical problem of evil: how do we move toward a world where there is less of it?

In fact, a quick review of the history of projects to eliminate evil suggests that they are a primary cause of evil. To anyone sane this is a suggestion that philosophers and theologians are doing it wrong when it comes to studying evil. After all, if a medical treatment resulted in more deaths than the conditions it was supposed to treat we would, with the advent of scientific medicine, likely reject it. But philosophy and theology are designed to be resistant to mere facts, and have for those same thousands of years claimed the study of evil as their exclusive domain because no one else was doing it.

Fortunately, that is no longer the case. Evil by psychologist Roy Baumeister is an excellent review of empirical data on evil, with particular reference to what causes it and how it comes to dominate some human landscapes but not others. Throw away your Bible, Quran and Little Red Book, if you want actually do something to reduce the amount of evil in the world, and read this book.

Baumeister starts with by identifying “the myth of pure evil” (MPE) that is the canonical model of evil dominating discourse across history and cultures. The MPE views evil as unmotivate attack on a pure innocent that is enjoyed by the perpetrator. Regardless of homilies about banality, this is the image of evil we are fed again and again in fiction and the news (insofar as the news is distinct from fiction.)

Baumeister goes on to study actual instances of evil, from the Holocaust to serial killings to the Cultural Revolution and shows they almost never conform to the MPE. So if you want to understand evil as it actually exists rather than the myth, you need to restrict yourself to the data, not fictional representations of evil.

Using this approach, Baumeister identifies four primary causes of evil:

  • Fragile egotism
  • Material gain
  • Utopian idealism
  • Sadism

The data shows that the last of these accounts for about 5% of actual evil acts, although it is the only one consistent with the myth of pure evil.

Challenges to one’s high self-regard are a common motivator for interpersonal violence, which suggests the “self-esteem” movement has likely led to more evil rather than less. People with low self-esteem tend to be passive, not evil. To have a meaningful challenge to one’s ego one must have a fair-sized ego to start with. Secure self-esteem is not much of an issue, because challenges will be shrugged off. But insecure self-esteem is a big problem, according to the actual data.

Material gain–often further enabled by group dynamics that diffuse responsibility, which Baumeister discusses at length–is a motivator for much evil. This should shock no one. Nor should the role of utopian idealism in the perpetration of evil, to the extent that anyone who says we must change everything via revolutionary overthrow of the existing order should be immediately ostracized from polite society before they start spewing conspiracy theories.

Baumeister examines the way we justify evil, and particularly the different lenses through which perpetrators and victims view evil. Evil acts are frequently distorted, and research has increased the plausibility of the proposition that both victims and perpetrators distort events to their own advantage by about the same amount when its at all possible to do so, as particularly happens in cases of interpersonal violence.

The role of self-control in preventing evil is a big focus, and how guilt acts to enable self-control is treated in detail. I found Baumeister’s observation that guilt is the mirror-image of self-esteem quite insightful: self-esteem benefits the individual at the cost of the community; guilt benefits the community at the cost of the individual. But of course we are social primates, so what benefits the community also benefits us. There is a sociological dimension to these ideas that needs to be more deeply explored.

Needless to say, I’m a fan of the book. This is the kind of thing the world needs more of if we are going to get a grip on evil and actually do less of it. Is there anything more important, really? Many people claim to be interested in “fighting evil”. This is what the fight actually looks like.

One of the big practical pieces of advice that comes out of this kind of study, which is consistent with what advocates of non-violence have been saying for decades: if you want to stop evil, look for ways to deescalate. Because victims see evil acts as much worse than perpetrators do, what look like just and proportionate responses to victims look completely disproportionate to perpetrators. This is hard advice to follow, but if we can attach our feelings of efficacy and power to the knowledge that by deescalating we have promoted good and fought evil maybe it will become easier. Why, after all, would anyone be proud of doing something that they know won’t work?

Another useful bit of advice is: reserve judgment, and be explicit about it. If you’re given an order to do something evil, feel free to put it off for pragmatic reasons, but explicitly say, “I’m not sure about that. I can’t do it right now because of [some practical issue]. But once that’s solved I may still not do it because I don’t think it’s right. So I’m using the practical issue to get some time to think. Moral issues can take some time to work out.”

And finally: be aware of your capacity for evil. Everyone has it, in the eyes of our victims at the very least. The most dangerous, vile, disgusting, creepy person on Earth is the one who is convinced that they are incapable of evil. Such individuals have been the foot-soldiers in the armies of evil since the beginning of time, and if the pragmatic study of evil teaches us anything it is believing in our own righteousness, uncritically and unquestioned, is an important enabler of evil.

Paradoxically, self-doubt is also be an enabler of evil, so there is a fairly broad middle path of moral self-awareness we must walk, between the extreme of disproportionate reaction to perceived slights on the one hand and the opposite extreme of passively accepting genuine evils on the other.

Even More Things that Are Not Arguments

Canada is sending about 600 members of the RCAF and a dozen aircraft of various types to support Iraqi and Kurdish forces in their war with ISIS.

Here are some things that are not arguments:

1) “ISIS are EVIL! They are committing GENOCIDE! They are RAPING and MURDERING and ENSLAVING PEOPLE!”

This fails the test of argument because while all of these–with the exception of the claim regarding genocide, which is questionable–are true, they do not imply “therefore we must bomb them!” or “therefore bombing them will stop them!”

What follows from these statements of fact is, “Decent people are opposed to such things. Therefore we should consider what is the most practical means of stopping them.”

As even the most casual student of military history knows, bombing people does not always work to stop and organization like ISIS. Examples abound. Here are two.

As recently as a few years ago bombing in Libya, whose purpose was:

“an immediate ceasefire in Libya, including an end to the current attacks against civilians, which it said might constitute crimes against humanity” … “imposing a ban on all flights in the country’s airspace – a no-fly zone – and tightened sanctions on the Qadhafi regime and its supporters.”

resulted in an outcome that has been described as:

The country has been subject to ongoing proliferation of weapons, Islamic insurgencies, sectarian violence, and lawlessness, with spillovers affecting neighboring countries including Mali.

And in Kosovo in 1999, where the outcome was marginally better but not necessarily closely related to the bombing:

Yugoslav President Milošević survived the conflict and declared its outcome a major victory for Yugoslavia. He was, however, indicted for war crimes by the International Criminal Tribunal for the Former Yugoslavia along with a number of other senior Yugoslav political and military figures. His indictment led to Yugoslavia as a whole being treated as a pariah by much of the international community because Milošević was subject to arrest if he left Yugoslavia. The country’s economy was badly affected by the conflict, and a year later, popular disillusionment with the Milošević regime led to his overthrow in October 2000.

Thousands were killed during the conflict, and hundreds of thousands more fled from the province to other parts of the country and to the surrounding countries. Most of the Albanian refugees returned home within a few weeks or months. However, much of the non-Albanian population again fled to other parts of Serbia or to protected enclaves within Kosovo. Albanian guerrilla activity spread into other parts of Serbia and to neighbouring Republic of Macedonia, but subsided in 2001. The non-Albanian population has since diminished further following fresh outbreaks of inter-communal conflict and harassment, and veterans of the officially disbanded KLA are threatening renewed violence if their demand for secession is not fulfilled.

So anyone who claims “ISIS is evil, therefore we must bomb them” needs must give some account as to why they think bombing them will be particularly effective in stopping them. They also need to explain why it won’t have the opposite outcome: external assault generally increases support for unpopular state organizations, thereby plausibly increasing their lifespan, and resulting in more murders, more rapes, more enslavement than if they had been left alone.

This is the cold, appalling truth. It may well be in the case of ISIS the forces in play argue for the kind of military intervention that is now in progress, but that case has not been made, and certainly is not made by anyone who simply says, “ISIS is evil” as if that was in any way an argument for it.

2) Are you a member of the armed forces? Got family in uniform? So shut up!

People who deploy this non-argument apparently feel that militaries ought not to be under civilian control, or that only the 600 members of the RCAF (and their families) are legitimate voices in this debate.

In reality, our armed forces are staffed by volunteers. They knew they would be under civilian, democratic control when they signed up. To suggest that those of us not in uniform have no say in how they are deployed is to engaged in an assault on Canadian democracy itself… perhaps such people are actually in league with ISIS, which appears to be no fan of our democratic institutions.

3) The government didn’t allow a debate!

It is the constitutional role of the government to decide when war is appropriate policy. People who make this non-argument are apparently confused as to the roles of the government and the Commons.

For myself, I am obviously unconvinced that the strategy of airstrikes being planned is likely to be effective in its stated goal, which is to degrade the ability of ISIS to make war. Tactical airstrikes, as have already been used to good effect in the evacuation of the Yazidis and in other cases, are demonstrably effective at winning specific battles, but as overall strategic policy airstrikes are at best highly problematic. It may be all we can do, politically, but I am not alone in thinking it won’t do the job, and I genuinely worry that it will lengthen the brutal reign of the ISIS.

To make an argument for bombing ISIS you have to do the following:

1) Show ISIS is evil (not difficult)
2) Show that bombing is more likely to prevent them from doing evil by either disrupting individual operations, destroying basic capacities, or changing their minds about the wisdom of being evil than any of the cheaper, less deadly alternatives.

It is the latter issue that has not been debated. Clearly humanitarian aid, nation-building, etc are not going to stop ISIS from being evil in the short to medium term, although some of those things may have their own benefits that make them worth the cost.

But are there other approaches? And on the evidence how likely is it that bombing them will help rather than make things worse by hardening their local support in areas where they might otherwise be unpopular?

Advocates of bombing appear to me to be like people who are facing a large crowd of refugees on the far side of a deep and dangerous canyon. “We must do something!” they scream, and immediately start felling trees to build a crude bridge, whilst ignoring the wreckage of bridges past that bestrew the canyon floor, complete with bleaching skeletons of those who were on them when they collapsed.

In such circumstances we might like to talk to an engineer to see what can be done to make our new bridge more effective, rather than insisting that we must rush off and do the very first thing that comes to mind.

There are actually people who study the effectiveness of war and various tactics, and while such studies are still in their infancy the general answer regarding the effectiveness of limited military intervention is “not much”.

In the present case, we have the opportunity to do a case study. Prime Minister Harper has said clearly that objectives of the current mission are:

Let me be clear on the objectives of this intervention.

We intend to significantly degrade the capabilities of ISIL.

Specifically, its ability to either engage in military movements of scale, or to operate bases in the open.

This will halt ISIL’s spread in the region and greatly reduce its capacity to launch terrorist attacks outside the region.

To be clear, this will not eliminate ISIL nor automatically ensure that alternative governance is able to occupy its space in Iraq or Syria.

It will, however, open the opportunity for others to do so.

But again to be clear, while ISIL will not be eliminated, the risks presented from the territory in which it operates will be significantly reduced to those of other similar ungoverned spaces in the broader region.

I count these six objectives:

  1. significantly degrade ISIL’s ability to engage in military movements of scale
  2. significantly degrade ISIL’s ability to operate bases in the open
  3. create opportunity for unspecified parties to occupy current ISIL-held territory and impose non-ISIL governance on it
  4. reduce the risks presented from ISIL territory to those comparable to other ungoverned areas in the region
  5. acting now precisely to avoid a situation that was clearly headed to a wider, protracted and much more dangerous conflict
  6. avoiding a long-term quagmire in the region

I assume by “other ungoverned areas in the region” he means things like Pakistan’s tribal lands?

He is clear that degrading and containing ISIL is the goal, not eliminating it, although if Iraq or Syria want to follow up they are clearly encouraged to do so.

These objectives are measurable, and in the next few days I’m going to see if I can dig up data on a) what kind of mass movement of troops ISIL is currently engaged in, b) how many and what size bases ISIL has in the region, and c) what measurable risks ISIL poses to adjacent states (notably Iraq and Syria, but also Turkey, Kurdistan, Jordan, Saudi Arabia and even Iran.)

If our opposition parties were any good, they would be doing this kind of thing instead of engaging in pedantic nitpicking, expressing a desire to micro-manage the deployment, and making juvenile jokes.

Guns, Drugs and Laws

What is the role of law in a free and democratic society?

Consider the data in the following areas:

In each case, there is a clear argument to be made that laws restricting popular activities have very little effect.

Prostitution and alcohol are both completely illegal in Saudi Arabia, and subject to extremely harsh penalties. There is no difficulty in getting access to alcohol, and little difficulty in getting access to prostitutes. During prohibition in the US you could buy Canadian booze more cheaply in Detroit than Windsor.

Russia has the highest per capita abortion rate in the world–almost ten times that of Canada. Russia restricts non-medically-necessary abortions to the first 12 weeks of pregnancy and imposes a several day waiting period to allow women to “reconsider their decision.” Canada has no laws restricting abortion whatsoever. None.

Portugal decriminalized possession of moderate amounts of drugs (about 10 days normal usage, although I’d love to know how they determined that) and has seen a modest decline in use. The US continues to keep its place as the most incarceration-friendly jurisdiction on Earth, beating out China, Cuba and North Korea in no small part thanks to its extremely harsh and pervasive drug laws. Despite this, drug use in the US has not changed significantly since the beginning of the “War on Drugs” in the 1970’s.

Firearms ownership in the US was 43% in 1964 and 43% in 2012, and never varied much in the intervening decades despite various changes in federal firearms regulation. In Canada, the much-loathed long-gun registry never had much impact on gun ownership and had no measurable effect on gun crime.

Today, it is possible for anyone to build a working AR-15 using a $1200 micro-mill to finish an 80% lower receiver. Will this and similar technologies like 3d printed guns have any material effect on the availability of firearms in the Canada?

I doubt it.

As near as I can tell from the data, laws have very little effect on otherwise popular activities. This is not to say that laws are unnecessary: they codify the boundaries of acceptable behaviour, define due process when someone is suspected of getting out of bounds, and specify punishment or other responses when someone is found to have gotten out of bounds. These are all good and valuable things. In the case of some crimes–white collar crimes in particular–laws may actually be effective in regulating behaviour.

In the case of access to widely popular goods and services–drugs, prostitutes of either sex, pregnancy termination, alcohol, and firearms–it is reasonably clear that no matter what the law says, people will find ways to access them.

In Canada, we have pretty robust gun laws, and its basically impossible for anyone who is not a police constable, a member of the armed forces, or a member of a licensed gun club to own a handgun. That’s because Canadians don’t have much interest in gunning ourselves down in the street. Americans–at least a significant sub-population of Americans–do, so no amount of gun regulation is going to change that.

To be clear: this does not mean that Canada does not need laws against gunning ourselves down in the streets. It means that those laws are an effective realization of our popular will, and without the popular will the laws would be ineffective in changing our behaviour. The laws are effective and useful because we don’t want to gun ourselves down. In the US the laws are ineffective because enough Americans believe in the freedom to gun Americans down in the streets that it continues to happen no matter how much the majority decries it.

Nor does the minority in favour of something have to be all that big before it becomes able to subvert the law in this way. The Socialist German Workers Party was only about 5% of the German population in 1932, but they were ridiculously effective at influencing the overall course of German history using tools of propaganda to lead the battered populace to accept and support policies that were later passed into law. In the modern world, in part thanks to widespread access to information, it has been more difficult for any group of murderous nutjobs to gain a similar degree of control, but they have still been able to impose crazy laws on the rest of us and to subvert sane laws when they have been passed.

This works both ways: a minority of Americans or Canadians are drug users, but that minority is large enough that drug laws are ineffective no matter how draconian. A tiny minority of Americans support unrestricted gun ownership, but that minority has been effective in using propaganda tools to stymie any serious attempt at regulation. A minority of Canadians (one hopes) employ sex workers, but that minority has never been much troubled by laws against prostitution. And so on.

All of which is to say: a remarkably high degree of consensus regarding what constitutes acceptable behaviour seems necessary before the practice of codifying it into law is particularly effective, and advocates of laws to control or limit behaviours they don’t approve of consistently under-estimate this effect, and frequently speak as if passing a law against something was somehow related to lowering the incidence of something in the general case.

The data show clearly this is not so: laws against widely popular behaviours are ineffective at lowering the incidence of those behaviours, and generally detrimental to society in other ways. Anti-drug laws ruin more lives than drugs. Anti-abortion laws make abortion unsafe rather than impossible. Anti-prostitution laws endanger prostitutes rather than eliminating them. Prohibition enabled organized crime far more than it disabled access to alcohol. And so on.

It follows from this that 3D printed firearms will have an impact in the US, but not much in Canada. Criminals in Canada can get hold of guns now, but mostly don’t because they aren’t worth the trouble. Burglars in Canada are rarely armed because homeowners in Canada are rarely armed. This gives us a higher burglary rate but a much lower rate of armed burglars: you are twice as likely to have an armed burglar come into your home in the US than Canada, even though Canada’s burglary rate is 1.6 times higher than that in the US.

This is a prediction then: we will see a rise in the US of 3D printed and home-machined guns by criminals in the US, and we will not see a comparable rise in Canada even though Canada’s gun laws are completely ineffective at preventing such a rise. Come back in a few years and see if I’m right.

How Bad is the Porn Industry?

Some quotes (a few words have been changed or omitted to hide identities):

  • I am overwhelmed with sadness, panic, fear, despair. I know I want to quit, but at this point it’s been 9 years.
  • I am so sick of being poor and pathetic. My life sucks.
  • My coworkers are mean, bitter people, with even more controlling dictatorial people who lead them. It is a toxic place. As soon as I am able, I am leaving.
  • The worst decision of my life. And pay isn’t even that great.
  • I lacked the feeling of connection that I needed to survive. Outwardly I seemed content, but I was dying inside.
  • I finished ten years ago and still wonk around feeling bad
  • But to be honest, I have disliked it for a very long time, and just kept thinking that if I stuck it out things would improve and I would work out the nerves, etc. Also, I have had a really hard time admitting that I may not be cut out for it.
  • I’m learning a lot about myself and about the whole fucking process. Just when I think that my eyes have been opened and I’m finally aware of what a sham all this stuff is and what I need to do to get the hell out of here, I have another realization.
  • So I LEFT MY ABUSIVE MANAGER for another, significantly less abusive one. He was a bigshot and I was terrified he would shut me out and my career would be over because he was unpredictable and I’d heard of similar things happening to other people. NOTHING BAD HAPPENED and my new manager is much better. I feel like I took action, and generally freer. A bit sad that ‘not experiencing direct violence but still anxious and depressed’ counts as ‘much better’, but I wanted to share something slightly hopeful.
  • Over a year ago I told my managers I was suicidally depressed. They told me not to worry because you couldn’t tell from my work. Then none of us ever mentioned it again.
  • …an exercise in managing crushing anxiety and fear, and trying desperately to make them look like passion or talent. I could literally taste the adrenaline in the back of my throat for whole month. My gums bled spontaneously throughout the day.
  • My faith in my abilities and in myself at this point is almost nonexistent.

Awful, eh? Dreadful. Destructive. Inhumane. Clearly a domain that screws people up, or that attracts screwed up people. Harassment, violence, humiliation.

The thing is: it’s not porn. All those quotes are taken from blogs about academia.
