> the relative universality of the conservative–liberal spectrum Grey tribe members may beg to differ https://www.gsb.stanford.edu/insights/rise-liberaltarian

Anyone not living in a two-party system begs to differ, especially those living in countries where liberals are conservatives (in a sense the term conservative is used within the US).

Not really. Other country's liberals are the USA's Libertarians. They're much different than neocons.

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.

Truth doesn't really care about your sensibilities. It seems there is actually an art to finding the mind's construction in the face! What this is really telling us is that we should not be judging others on their political, sexual, ideological, whatever-ical affiliations. A person is a person and we should value them for that and only that. These other qualities may be more or less useful in some sense, but not in t…

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, ver…

There's evidence of inheritability of political orientation, since it is tied to personality traits. Given that, it makes sense that it is possible to predict political orientation through looks alone. After all, looks are also inherited traits. The article gets into this a little bit. They are able to predict traits like intelligence and honesty by looks alone.

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.

There's no such thing as a dangerous line of study.

Do you think people hundreds of years ago with different common political views - some of which we'd find abhorrent now - had different faces too? Someone should test this classifier on old images. Maybe it's just identifying fashion, not facial structure.

No, what would change is that you'd get people from hundreds of years ago expressing conservatism or liberalism _for the time_. It's neither fashion nor facial structure, it's more or less intensity of facial scrunch vs. innocence, or wariness vs invitation. This is going to hold true for all humans and indeed for similar enough animals so long as they have the ability for comparable postures and expressions (dogs and cats would have the capacity for posture but I think dogs are more capable of brow expression/mobility, and of course monkeys and apes are close parallels to human expression)

So you could, in a limited sense, tell whether you've got a hippie cat or one who wants the hippies to get off its litterbox :) the latter will give you more side-eye, and more of a narrowed gaze.

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…

Presumably some humans are terrible at this and others are as good or better than the machine. Of course, even someone who was very good (say 80% accurate) would be wrong about 1 person in 5.

Being honest about this equips a person with a useful hunch capability that will provide a long-term edge (perhaps as a detective, or in sales, or any of many other contexts where people-reading can help); less honest practitioners might become con artists, or consultants/coaches whose methods are not reproducible or even formalized such as Dave Grossman: https://www.insider.com/bulletproof-dave-grossman-police-tra...

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 wo…

I think people are already making those real world decisions, with or without being able to automate the process. The real implication here is that political ideology owes more to raw emotional biases than it does to analysis and introspection. It echoes a person's general attitude toward life in the absence of specifics. I would say this is not a revolutionary observation, but it's a confirmation through experimental means.
