Did the survey, except digit ratio due to lack of precision measuring devices.

As for feedback, I had some trouble interpreting a few of the questions. There were some times when you defined terms like human biodiversity, and I agreed with some of the claims in the definition but not others, but since I had no real way to weight the claims by importance it was difficult for me to turn my conclusions into a single confidence measurement. I also had no idea weather the best-selling computer game question was supposed to account for inflation or general growth of the videogame market, nor whether we were measuring in terms of copies sold or revenue earned or something else entirely, nor whether console games or games that "sell" for 0$ counted. I ended up copping out by listing a game that is technically included in a bit of software I knew sold very well for its time (and not for free), but the software was not sold as a computer game.

Also, a weird thing happened with the calibration questions When I was very unsure which of a large number of possible answers was correct, and especially if I wasn't even sure how many possible answers there were, I found myself wanting to write an answer that was obviously impossible (like writing "Mars" for Obama's birth state) and putting a 0 for the calibration. I didn't actually do this, but it sure was tempting.
