This thread is about Intelligence Quotient (IQ) as in whether it can determine the true potential of a person and the reliability of such test or other similar psychometric tests.

Also, I'd like to discuss whether the "born" genius is better than the hard worker.

I've never been tested myself for IQ but I've met people who have and they don't quite match what you'd expect from them. One of my friends got about 150 but he's a person who cannot do anything by himself.

So, have you been tested? How reliable do you think it is?
