Sam Harris Responds

Probably you find yourself as am I, baffled by the recent spat of Twitter hate emanating from NNT towards @SamHarris, @sapinker and many others. The Steven Pinker spat goes back to a 2009 NYT book review by Pinker of Malcolm Gladwell’s “What the Dog Saw”, where Pinker beats up on Gladwell (see also). Taleb, featured in the book, by then a friend of Gladwell, comes to the rescue. Pinker is surprised, Taleb doubles down. From Maclean’s 12/10/2012:

So, when the renowned Canadian-born Harvard psychologist Steven Pinker penned a critical review in The New York Times of fellow Canadian Malcolm Gladwell’s novel, What the Dog Saw, Taleb rushed to Gladwell’s defense. “I got furious. I feel loyalty for someone who does something nice for you, when you are nobody.” Taleb wrote a scathing critique of Pinker’s research in The Better Angels of Our Nature: Why Violence has Declined. In his critique, titled “The Pinker problem,” Taleb claims Pinker’s book is riddled with errors in sampling and doesn’t “recognize the difference between rigorous empiricism and anecdotal statements.” Pinker responded with his own paper in which he writes, “Taleb shows no signs of having read Better Angels.”

NNT’s beef with Sam Harris is a little harder to track.

The debate Harris talks about, which seems to be the nexus of NNT’s beef with him, happened in 2009.
In a recent podcast, Sam Harris responded to NNT’s Tweets and shared some context.

The entire debate, from La Ciudad de las Ideas 2009, full and unedited, can be found here. What follows are relevant clips from NNT and then Sam Harris.

The neuroscience papers Sam Harris refers to are:
Neural Correlates of Religious and Nonreligious Belief
Functional Neuroimaging of Belief, Disbelief, and Uncertainty (pdf)

Statistics of Violence as Special Case of Fat Tails

A lecture summarizing the paper on violence with Cirillo to MIT and NECSI data scientists, mostly explaining to data scientists how to work with fat tails and only indirectly addressing Pinker by responding to those fooled by the illusion of drop in violence:

A lunch discussion at MIT with computer science-data science researchers from MIT and NECSI. The talk is mostly about the methodology for dealing with fat tails, with application to violence.
We show which claims can be made, and which ones cannot be made, from data, and “violence has dropped” is not one of them. We do not focus directly on Steven Pinker’s popular science book (owing to some deficiencies), only indirectly as some people in political science made reference to it.

This is a one-page answer as the journalist-passing-for-scientist Pinker has been working the press to show that violence has “dropped” since 1945, citing political science bloggers innocent of fat tails, who seem clueless about the difference between data and information. How to separate anecdote from evidence, sampling error from truth, journalism from science? Well there is something called a “test statistic”.
This also illustrates how to do rigorous statistics in the absence of a textbook recipe for a fat-tailed process, by means of Monte Carlo analyses.
I will be teaching a course called “Extreme Risk Analytics” at NYU-Engineering this fall and will have to produce an 80-p lecture notes booklet, which I will write progressively from interaction with the class. SILENT RISK is too advanced, so I need a more introductory book.

E.O. Wilson, Nowak et al. wrote a paper on altruism…

E.O. Wilson, Nowak et al. wrote a paper on altruism that triggered a huge angry reaction (particularly by science journalists Steven Pinker and Richard Dawkins). The paper (linked) contained words with a mathematical backup.

More than 100 biologists signed a petition asking for retraction. And the math was not remotely addressed. Yet if the paper is wrong, math should be 1) wrong (which can be shown incontrovertibly) or 2) inadequate for the task, which is trivial to show by expansion of functional/parameter space, as I’ve been doing with economics. (But here the math was addressing flaws in the math that was behind the theories supported by Dawkins and others). Neither of these 2 were done. Having seen the bitter attacks on Edge.org & elsewhere, including comments by biologists that Wilson was “senile”, I spent some time scrutinizing the math: it is impeccable, though unsophisticated by mathematical finance standards. The beauty of mathematics is that it is *impossible* to be misunderstood.

They were attacked in a verbalistic manner. In other words, with BS. I view Richard Dawkins with intellectual revulsion as the perfect bullshit artist on the planet.

The lesson is obvious. Fughedabout supplemental material and backup. Put the math in the front, words in the back, particularly when the words are only there to explain the mathematical reasoning. Alas, it is necessary. Math is distortion-free, which repels the distorters…

(Note the earlier idea came from Yaneer Bar Yam and his idea can be related to the one in antifragile that averages miss Jensen’s inequality. A function of a mean is different from the mean of a function).

PS- I am publishing a paper about the Pinker fallacy with his verbalistic/BS interpretation of risk of war and “drop” in violence. The math comes first, words later. The same with the 2nd version of the precautionary principle.

PPS- When I wrote Antifragile, which is defined as a locally convex reaction to a nondegenerate stressor, the technical material was in another paper. It turned out to be a mistake as BS artists were arguing about “resilience” (which is nonconvex), etc. The math is first, even if it repels readers.

I have to give credit where credit is due. I was at dinner with two people who said that Steve Pinker stood by them at a difficult moment, when it was very unpopular to do so, when other academics abandoned them. And he went out of his way to do so. Very honorable. So one should respect the man, without setting aside the statistical problems, or perhaps look at the statistical problems as good news: here is a man worth fighting against.
