It might be that I have gotten to cynic but if you measure 6 variables it's more likely that one of them get a statistical significant result then if you first turn those 6 variables into 2 variables via PCA.

My project gives a proof of concept for what I'm talking about in the context of social psychology. I've never seen such an application. So no, it's not just the realization that it could be applied, it's also giving a proof of concept: that's why it took ~1500 hours rather than ~10 hours.

That probably where there's something I don't understand. I don't understand why the analysis took ~1500 hours. Spending that much time with a dataset also instinctively triggers "fishing expedition" in my head. I don't know to what extend that's warranted.

I'm not sure that you have shown that it makes more sense to interpret that factor individual preference is about intelligence and sincerity than that it's about the value of fun.

As far as I can see it could also be that fun&physical attractiveness is simply more valued.

So I'd strongly encourage you to pursue your ideas more. I've been looking some at the General Social Survey data, where I haven't yet found something highly nontrivial (maybe I'm looking at the data the wrong way, or maybe it's just not a good dataset for this). I'd be happy to share my code with you / a cleaned form of the data, if you're interested in exploring factors for political labels.

In the case of the spending effort on the GSS I can't envision what success looks like. It's straightforward to find PCR factors but I don't know how to put them to good use.

A more interesting project would be to explore LW's ideological landscape. It would be very interested in how various rationalist beliefs interact with each other. Does seeing yourself as an "aspiring rationalist" correlates to beliefs on UFAI risk?

Having a project that searches where the main dimensions of disagreement in this community would be valuable. Maybe 300 questions that are answered on a Likert scale. Maybe 150 rationality questions, 100 big 5 questions and 50 autism questions.
