Some data points:
IQ (age 7, 14, 20) = ~145-150 S-B
SAT (age 16) − 1590 = ~150 S-B
iqtest.dk (age 29) = 133 S-B
sifter.org/iqtest (age 29) = 139 S-B (159 euro scale)
I don’t use my spacial skills in my daily work they way I used to use them in my daily school work, and both online tests seem to measure only that.
I found the second test much more difficult—there wasn’t enough information to derive the exact missing item, so you had to choose things that could be explained with the simplest/least rules. There were some where I disagreed that the correct answer had a simpler rule-set. The problem style is also highly learnable, and I question the diagnostic value of “figuring out” that you’re looking at a 3x3 matrix where operations occur as you move around it, but various cells have been obscured to make the problem harder. Not including instructions makes it feel like there’s a secret handshake to get in.
