I don't know a lot about psychology. The only things I've read are pop-psych articles like this about "traits", "D-factors" and "personality types", which you got to admit do sound a bit much like pseudo-science, or at least not telling the full story. It's useful, for sure, but I'd like to know more about the formal methods employed in modern psychology today. I imagine statistics, surveys and telemetry perhaps being key, but like all methods based in data - You have to be very careful; testing methodology and interpretation biases can heavily influence the results.

I think psychology could bring valuable insight into the future of AI as well. It's a shame that most psychologists involved in tech are in HR/communications or at best tasked with keeping people addicted to whatever social platform they are building.
