I consider giqtest.com also professional/scientific, despite being taken online.
(I understand the general aversion towards online tests, and don't mind the current wording.)
Respondents with high IQ seem more likely to have taken official tests, though; doesn't this overestimate LW's mean?
So, how did it go? I might come the next time...
Another lurker that took the (full) survey and signed up...
I discovered LW last year through gwern.net
My biggest barrier to registration was the risk of more procrastination. So, thanks in advance for any encouragement!
Thanks for organizing! I'm looking forward to meetup.
