Gimme 30

Dave Asprey, the Bulletproof Executive, claims that his IQ was raised 30 points by taking creatine and going through Dual N-Back training exercises.

This is one of my smaller pet peeves: talking about IQ scores as though the scale was linear. Increasing IQ from 100 to 130 means an increase from 1 in 2 to 1 in 44, whereas increasing it from 130 to 160 means a jump from 1 in 44 to 1 in 32,000. Another 30 points and you're 1 in a million.
