I got the answer in under 2 minutes (didn't time it exactly). However, when I first identified my answer candidate (answer 2), it was probably about two thirds of the way in. I got the correct answer by going across at first, but then spent additional time double checking my work using columns, and then double checking my answer before "committing".

I've taken a couple of online Raven's Matrices type tests in the past, but that was a while ago, so I don't believe memory played too much of a role. However, I seem to have internalized the idea that IQ tests are trying to bait you with obvious answers, and as a result, I end up taking too long double checking my work.

I suppose the only way to get over this lack of confidence in my intuition is with practice, but I'm wary of diluting the feedback I get from the occasional IQ test due to the 'practice effect'.

It's a bit of a catch-22. Any thoughts would be appreciated.
