Hmm, I'm not sure so whats the ratio of intelligence to imbecility? something like 1 intelligent per 9 imbecile ones seems rather arbitrary. The author makes an interesting argument that imbeciles take advantage of the intelligence of others, and therefore intelligence actually makes everyone dumber. However, I find this theory to be flawed. In my view, when intelligence achieves something new, it simply leads to more questions and new challenges, the process never ends.

The author does make some valid points, about how evolution prefers imbeciles, such as how imbeciles tend to have higher reproductive rates, and how the Neanderthals, who were the "most intelligent" hominids due to their larger cerebral volume, ultimately went extinct because their bigger heads made childbirth riskier for females, while other hominids with smaller heads had more successful reproduction.

But as I read this, I can't help but feel the author is trying too hard to make the data fit his overall theory.
