Anyone know if there's any truth to his statement about the IQs? Hard to believe that only roughly 7% of the population has an IQ of over 105.
I don't know what the exact statement was about IQs because I didn't read the thing, but saying only 7% of the population has an IQ over 105 shows a complete misunderstanding of what IQ is.
IQ is a measure of the average intelligence one has in comparison to other people. 100 is
always the average. If you have an IQ of 100, you are always (on average) directly in the middle of everyone currently.
Not only that, it is always equalized so that it is forced into a bell curve shape.
Here is the distribution of IQs:
Note: that is always the distribution of IQs. Even if average intelligence rose by 10 IQ points, the new average wouldn't be 110, but still 100, because that is how it is designed. To claim otherwise means a misunderstanding of the system used.
