Answered the survey, including the bonus questions. Took me 32 min altogether. Comments:

How many people are aware of their IQs? I'm from Germany and have never taken an IQ test. Is knowing about one's IQ common enough in the US that not making that question a bonus question made sense?

There were quite a few questions (e.g. estimate weekly internet consumption, estimate how often you read about ideas for self-improvement) which felt pointless - how could you possibly get accurate estimates from people, given how ambiguous these questions were, and how difficult these estimates are?

The money question: After I failed to come up with a unique passphrase, I chose cooperate and left the rest blank. This kind of stuff tempts my perfectionism, and that's a lose-lose situation for me.
