So Jordan Peterson was giving a talk about IQ testing. This question came up and the “correct” answer was 3. Many people including myself went with 7.
So I discovered that both answers are correct depending on how you choose your answer.
3 is correct if you like even distribution so tgere are an equal number of everything in the whole square. Ie 3 side bar colour, 3 triangle colour, 3 vertical colour.
7 is correct if you like pattern recognition. 2 colour bars repeating per row in both up down and left right directions.
I am curious what that says about intelligence and problem solving for the groups who chose one way or the other.
