Were the humans experts or just random people though? The real question is whether the tool can beat a lookup table of age, race, and gender probabilities. The tool isn't going to be winning points of phrenology here. Weight, hair color, and hairstyle would also likely tell you a lot. I don't have any particular reason to believe this tool wouldn't work, but let's not pretend it's getting their by phrenology-esque to…

It further notes: > Accuracy remained high (69%) even when controlling for age, gender, and ethnicity.

How does one calculate a metric like that?

Does anyone know what the accuracy of a prediction is if you use only those three factors -- age, race, and gender?

All numbers are Biden-Trump in 2020: People under 30: 60-36. White men: 38-61 Black women: 90-9 So there are definitely some strong predictors there. Source: https://www.businessinsider.com/2016-2020-electoral-maps-exi...

If only the researchers were as smart as you apparently think you are and somehow remembered to control for these very obvious factors. Oh yeah, they did.

you think its a joke?

What on earth makes you think calling anyone anything is off limits?

I'll call a spade, a spade. Any day of the week, week of the month, or month of the year. Not being willing to do so is a disservice to everyone around you, and even to the person in question, who may be caught in the Nietzchean transformation into the very monster they putatively fight; something even the people of Israel may be served well to remember. It's one thing to be besieged on all sides, it's another to ante up atrocity on top of atrocity.

You don't get to claim you aren't the monster when you're doing the Same. Bloody. Things. It isn't different this time. You aren't justified doing it, and we've all seen where this movie goes before, your attempts to control the narrative aside.

An African American executive espousing abusive workplace policies targeting a disadvantaged or otherwise unable to realistically defend themselves group of workers is a fair game target for being called out as a slave driver or plantation owner. A people espousing the employment of phrenological methods for the purposes of undesirable population control are a dead on ringer for the Nazi political regime circa 1940. No it doesn't dilute the message. It reinforces that evil is often seductive and insidious in it's tendency to convince even good people that they are doing the right thing when by all objective definitions they most certainly are not.

You, sir, would be well advised to think through the consequences of your pleading. To minimize the usability of highly disambiguously responded to subject matter is to unfasten society's overall moral compass by atrophying the ability to sense the fundamental ways in which the evil that drove that atrocity was itself a composite of goods to the people doing it.

I hear you, and I in no way do not feel sympathy for the victims of those atrocities. Quite the opposite. I have a near all-encompasding moral mandate to ensure that the confluence of circumstances, and lack of accountability holding, or voices of reason that led to such vile rhetoric taking root never happens again. I will call out BLM for their civilly destructive tendencies, and lack of restraint of those that step out of line at their protests; I will call out the woke movement for doing the same thing you espouse, thus ensuring a fields of ignorance and uncommemorated infamies evils for previously experienced to grow and burst forth out of.

If people weren't so prone to doing evil things thinking they were doing the right thing, nobody would have to call them out.

Evil, just as hope, springs eternal. It is our duty as the gardeners of our species collective morals to be on top of it. That does not happen by locking the ugly away in a box or by ignoring it. What you ignore has just as much of a positive consequence as what you willfully do. The act of willful ignorance is the one great unforgivable intellectual sin.

I don't really buy this study. If humans can't get a better accuracy than 55%, I'm convinced this vector is leaking some obvious (maybe high-frequency) information that doesn't have anything to do with the face. E.g location of the person.

When I read a paper like this I'm looking for four things: (1) the data, (2) the benchmarks, (3) the architecture, (4) the controls/ablation. 1. The data: "We used a sample of 1,085,795 participants from three countries (the U.S., the UK, and Canada; see Table 1) and their self-reported political orientation, age, and gender. Their facial images (one per person) were obtained from their profiles on Facebook or a popu…

What stood out to me was

> Their facial images (one per person) were obtained from their profiles on Facebook or a popular dating website

so of course the first thing to comes to mind is "how good of a predictor is just knowing which of those two sites the image came from?"

I was not commenting on the main article about the research, but instead on the comment by user karaterobot that I am responding to which -- if I am interpreting it correctly -- asks the question how good one can guess purely based on those 3 demographic axes.

As you note, the researcher's predictor appears to do better than random even controlling for these obvious demographic skews, which is fascinating.

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 (the U.S., Canada, and the UK), environments (Facebook and dating websites), and when comparing faces across samples.

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

So even filtering for the extremely limited number of things that you allow us to find problematic, by their own admission : - they know that it's actually probably "working" (lol 72%) because of other biases they didn't take into account - Ultimately it puts people into 2 bins which are both huge and disparate and reduce complexe multi-dimensional elements to a meaningless binary.

cool cool cool.

This is the exact question I came to the comments to find. The abstract states: >Accuracy remained high (69%) even when controlling for age, gender, and ethnicity. To give some context, chance is 50%, human guess is 55% and a 100-question questionnaire is 66%. Personally, I am surprised that the accuracy remained that high when controlling for the three variables I would have considered most telling in the determinat…

In fact, I'd put it another way. I'm surprised the accuracy was not higher when you ADDED IN the three variables to the 69%.

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.
