So which is it? Raising IQ or making them more intelligent?
Can't really "raise the IQ" because it's defined:
"For modern IQ tests, the raw score is transformed to a normal distribution with mean 100 and standard deviation 15. This results in approximately two-thirds of the population scoring between IQ 85 and IQ 115 and about 2 percent each above 130 and below 70."
