I think this is a very dangerous line of study. I can easily see these results getting used to forward racism and other appearance based discrimination.

I honestly don't see the danger here. This is an incremental addition to an already very large body of research that's existed for a while. And racism isn't rational. You can't combat racism by suppressing research. If a study came out demonstrating that Alpha Race is smarter than Beta Race, and that Beta Races is smarter than Gamma Race. The racist Betas might use that study to justify their hate for Gammas, but the…

Traditionally, by saying they have the wrong personalities.

I just wish people called it 'correlates' instead of prediction since ML algo's often fall in the correlation category, not the predicting one.

Is there some technical definition of “predict” that you are assuming?

I really hope not. 72% is impressive. But, when you're thinking of making any real world decisions based on it, 72% shouldn't really be considered much better than chance.

You shouldn't make any decisions on it, but it's striking that it works at all. It would be interesting to know why.

I have my suspicions about that, which are that people tend to mimic those they see around them. Which could well extend to how they hold their faces unconsciously. It would be not unlike the way we develop similar accents to those around us, just with different muscles. But that's a hypothesis that would have to be tested.

Sadly, if it holds up, it almost certainly would lead to people making real world decisions.

"Accuracy remained high (69%) even when controlling for age, gender, and ethnicity."

So your race accounts for less than 3% despite 89% of all black people voting left, that seams strange. I did not do the full math but just the ballpark numbers I entered in to my calculator says that it should account for about 11%. * 89% according to numbers from nbc Edit: So say I assume that every African American person I see votes left. 13% of the population is African American 89% of them actually vote left. 1…

The study looked at political orientation (liberal versus conservative or left versus right), not political affiliation (Democrat versus republican). 89% of African Americans vote Democrat for complex historical and sociological reasons. But they have a large diversity of political opinions: https://press.princeton.edu/ideas/the-roots-of-black-politic.... About 30% of Black people today identify as conservative, versus 10% in 1970. But Democratic Party affiliation has been in the 90% range throughout that whole period.

I think the key line is how much better this system is than humans attempting the same task: > Political orientation was correctly classified in 72% of liberal–conservative face pairs, remarkably better than chance (50%), human accuracy (55%), or one afforded by a 100-item personality questionnaire (66%). This isn't a matter of "recognize that old white people are conservative", because people will do that already, a…

As noted by gus_massa in another thread, the 55% figure for human accuracy is from a different study with a different datasets, so it's questionable how comparable the results are.

Sic transit "E pluribus unum"? https://en.wikipedia.org/wiki/E_pluribus_unum https://en.wikipedia.org/wiki/Melting_pot

Former Kaiser of Austria-Hungary, Franz Joseph, had a personal motto of "Viribus Unitis". That means "With United Forces". It was also used by A-H military. In practice, the multicultural empire was greatly weakened by incessant nationalist bickering. Once you have to declare that X is your strength or something similar, it most likely isn't.

Good counter-example.

I would argue that Diversity is necessary, but not sufficient.

("E pluribus unum" is -of course- the motto of the United States of America. Not the least of nations!)

"If we all reacted the same way, we'd be predictable, and there's always more than one way to view a situation. What's true for the group is also true for the individual. It's simple: Overspecialize, and you breed in weakness. It's slow death. "

Obviously it's looking at something . I feel like everyone is jumping to assuming the authors are implying it's somehow in the person's facial structure, but it doesn't say that. If it's looking at the quality of the photo, or the trim of the beard, that's still interesting. Among other things, it means that you know analyses like this might start cropping up everywhere you submit your photo (job application cover le…

Humans might try, but the same study says they're not good at it with only 55 percent accuracy.

Unfortunately people dont have to be good at something to advocate it or force it on others. Just look at all the 'detoxes, random diets, cultural remedies like trying to cure plague with wisky, bloodletting etc.

Our deductive powers havent improved much, they just moved to areas of our lives that are more nebulous. Fundamentally bloodletting and 'looks like a hippie, and hippies shouldn't work for a bank" are about on the same footing
