  "standard normal distribution" is a normal distribution with mean 0 and s.d. 1. To talk about whether intelligence follows a (one-dimensional) normal distribution we have to assign a number to it. That number is usually IQ, but by design the raw score is transformed to make IQ scores follow a normal distribution. So it is trivially true. If we want to go beyond that, what does it even mean to say, for example, "twice as smart"?
