Re: Facial recognition can predict person’s political orientation with 72% accuracy

This isn't a study that shows that people's faces indicate their political leanings. It's a study which shows that pictures that people select to represent themselves publicly have features that indicate political leaning.

Exactly. There was some fuss a while back about a similar classifier for sexuality. It turned out to be guessing mostly based on head tilt, personal hygiene and whether the person was wearing glasses. The physiognomy component was ~nonexistent even though it was publicized as though it weren’t. People intentionally if at times subconsciously present themselves in a way that signals information to kindred spirits. You…

I think that conclusion is at least as interesting as physiognomy. It's remarkable that a computer could be more sensitive to it than people.

According to Wikipedia only 51.3% voted for Biden/Harris.

The dataset was not restricted to voters.

Do you have data that includes non-voters? I haven't seen any; most polls are limited to voters.

I wonder if the study accurately reflects the lack of political common ground in the population. Are only 28% of us “moderates”? It’d be interesting to do the same analysis with photos of people taken 10, 20, 30, 40,... 100 years ago to see if the intersection (28%) grows/shrinks historically. Were we always so easily politically separable by our appearance alone? Has our appearance always revealed our political lean…

There's no definitive definition of "moderate". People who want to argue most people are moderate say the political middle is the 75% middle of the bell curve, while people who want to argue most people are partisan say the political middle is only the middle 20% of the bell curve. What is accurate to say is that political views in Congress have bifurcated (not a bell curve), and that people in America have "sorted"…

There is no bell curve. Political orientation is largely a self-referencing phenomenon. Outside the political elite, who have a high degree of ideological coherence, knowing a person's views on one issue is a loose predictor on their views on another. Gun-toting anti-abortion lesbians and pro-immigration free-market feminists are real, and they aren't some striking minority.

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.

A lot has changed, including nutrition. I would not be surprised if 17th century skeletons and body builds were observably different from the contemporary ones. In fact, at least height and weight of an average person is fairly different compared to the past.

And those are all non-genetic factors along the lines of other non-controversial things like "how wealthy you are will influence your political views," versus things supporting the "all political views are sacrosanct and can't be judged, because people can't help themselves" direction that 'plutonorm was suggesting.

Reality please don't bite me. This will probably be an Oxymoron :)

An interesting question, to me, is: how would you (personally) react if such an controversial and stigmatized factoid would be proven true at more than 5 sigma?

Would you be shocked? Or would you accept the outcome? And which of both would tell what of yourself?

There's a bell curve on each issue independently. This has been well established by surveys.

And therefore however you want to aggregate issues into an axis, you'll invariably find the political distribution to be normal.

It doesn't have anything to do with how coherent or not you find each party's platform to be.

So yes, it is fair to say that political views are bell curve-shaped. It's not an artifact of political parties.

I'd be curious to see the data. Measuring agreement is challenging. (Strongly Agree versus Agree mean different things to different people.) And polarizing issues tend to be multi-modal, thereby defying normal characterization.

Where one can create an objective x-axis, e.g. with increasing strength of regulation on a topic, one frequently sees non-normal preference patterns.

Good points and summary. Adding on to that, the following was from the abstract about 2 sentences in. Seems like some users do enjoy jumping straight to the comments! * 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%). * Accuracy was similar across countries…

"controlling for ... ethnicity" There's significant signal buried in here that is likely not controlled for, depending on how granular their controls are. White-German and White-Italian are much more (10-13 percent) likely to be conservative leaning than White-Irish or White-British. Hispanic-Cuban are more likely to be conservative leaning than Hispanic-Mexican.

In the US or generally?

I assume there's no way to actually verify how someone may choose to vote, assuming there's no record of that? I think there's huge value now that everything is being sent into a "machine" or "the algorithm" in fucking with it. Order sex toys from Amazon, show them you're into outrageous books and fool them into creating a fake profile of "you", based on your spending, browsing and other data you generate. I'd love t…

From Amazon's perspective you have not poisoned the well... you are someone who is likely to buy those things. Amazon does not care if you really like or even use them, it only cares if you buy them.
