I passed a mensa test. It was suggested I do it about 12 years ago.
It doesn't test creativity to a good level. Creativity is the real test of intelligence. The idea of thinking outside the box and not within predefined parameters like the mensa iq test.
Unfortunately I'm not creative. I wish for that more than my logical skills.
If you wanna get creative you need a lot of silent time alone:)
Not Reading, Not watching anything, Not talking.
Then try to fill the space with yourself:)
