> Their facial images (one per person) were obtained from their profiles on Facebook or a popular dating website. Not sure I’m entirely comfortable with that.

Perhaps conservatives and liberals upload different kinds of face images to the internet.

Not the issue.

The issue is potentially being included in a study unintentionally, that is impossible to anonymize, without prior knowledge or consent.

So... now, is it because people that came from the same regions a long time ago all happened to tend towards a certain political leaning and that just has stayed within families for that long?! Like a culture thing, but within families? In general, though, its amazing how little control we have over who we are despite the feeling that we are in control of it.

Could be but not across the board true. My parents are deeply liberal to the point of the Constitution be damned so long as their views are enacted in some way. I am just the opposite - a constitution conservative. I am aware of several friends families that are the same or opposite.

I think the key to you last comment is how much intellectual control someone has over their emotional response. I like to think I am pretty good with that at this present time. That was not always the case and may not always be the case.

> These self-selected, naturalistic images combine many potential cues to political orientation, ranging from facial expression and self-presentation to facial morphology.

I was going to ask how they controlled for the presence of compound bows & deer, trucks, and tank tops in the photos, but this implies they did not. Another one would be lighting palette, since that's going to be biased to regions as well. There is something to be said for it, as I'd say I have a %72 chance of guessing someones political orientation by looking at them as well, which someone once explained to me as being the effect of testosterone levels on the region around their eyes, but that sounded like folksy bro science.

Skin color. Features resulting from inbreeding. Features due to your gender. Features resulting from gender change.

Inbreeding?

I'm not sure where GP is going with this, but for example the Habsburger lower lip [1] is a easily identifiable feature from inbreeding in Western European nobles. If you can identify it it gives you a good clue about the socioeconomic class of the person, which gives you a good clue about their political orientation.

I'm sure many more subtle examples also exist.

Can you explain to me how that’s a bad thing? Differences among people do not make them more United and their bonds stronger. Literally the opposite is true.

Because the commonalities that exist between people help them overcome their differences, understand each other better and reflect on themselves.

I’m positing that more differences = weaker relationship. Are we agreeing?

> Their facial images were obtained from their profiles on Facebook or a popular dating website So, this seems to be doing profile picture recognition, not facial recognition. It's not like they're saying there are physical features in your face that give away your political affiliation - that is to say, putting two people's bodies under the same photographic conditions would probably not create this kind of signal.…

This meme[0] comes to mind. Is this AI picking up on the same types of cues represented below?

They tested this question specifically: > Both in real life and in our sample, the classification of political orientation is to some extent enabled by demographic traits clearly displayed on participants’ faces.

From there, it would seem that cues might come from how 'kempt' they appear, whether the head shot was from a party or for a resume, perhaps color and style of clothing, ... I.e., maybe not strictly the face.

If they’re wearing a face mask, if they’re carrying a tiki torch or storming the capitol building...

"To minimize the role of the background and non-facial features, images were tightly cropped around the face"

Though cropping can only do so much.
