I'd like to see some hot-shot detective try to get a random number from 1-1000 out of my head by using those techniques. Yeah, he couldn't.

That is because the stakes are too low to make you feel unsettled (in getting a random number). But if you knew you did something that could land you in prison and you were supposed to hide it, that would be a completely different scenario.

People go to jail for things they didn't do all the time, by the time you see those signs on the wall you better be nervous. Unless you like jail.

I'm surprised that "micro-expressions" and the work of Dr. Paul Ekman weren't mentioned given how hyped it was several years ago (there was even a drama series called "Lie to Me" I believe). Has this all been debunked?

"As a Homeland Security official told congressional investigators, “common sense” behavioral indicators are worth including in a “rational and defensible security program” even if they don’t meet academic standards of scientific evidence."

What does that even mean? ... like there is a separate standard of evidence and there is a "we can get by without evidence" standard of evidence?

It's a book, by Malcolm Gladwell. The comment said the audiobook is like a good podcast.

If it's a book by Malcolm Gladwell, I can't anti-recommend it enough. All of the Malcolm Gladwell books I've read have been tripe. Unless he has radically improved his writing and grasp of nuance in the last decade (and published retractions of his earlier books), his books are dangerous anti-knowledge which will make you feel smarter but actually be dumber. Gladwell takes an obvious, folksy thing, adds a bit of a tw…

It can mean no one has done a study of a thing or existing studies are poor.

I don’t know if that’s what the official means, but all kinds of common sense things never end up being studied because they’re commonly believed to be true.

Edit: having read the article more closely, however, it sounds like the official may be referring to things scientists believe they have debunked.

Sounds like code for ‘profiling’ post 9/11, where it took very little due diligence to ship someone off to Guantanamo or pick someone out at an airport. Conjecture based on the department in question, DHS literally exists because of Islamic terrorists.

I’ll add that I think profiling is a necessary evil in tense situations, and terrible as a blanket policy (racial profiling en masse).
