Seems like IQ tests are designed as an ego boost. You are good at math, have solid reading comprehension, and you have some common sense you are going to score well.
Everyone who takes one seems to score 130-140. Then again these are the online "fake" IQ tests. Or perhaps it's due to the sample of people taking these tests online, who knows.
All I know is that everybody thinks they have above average intelligence.
Except me though, I for one KNOW I have above average intelligence.
As for those other people...
