Is there some research you can point out that establishes cases where a lower IQ has been advantageous?
Additionally statistical conclusions are already established. Hardly worth arguing about all together. It is the things that aren't backed by statistical evidence YET, that are more interesting and worth talking about.
Honestly, I detect a thinly veiled personal ire in your response. Perhaps the bias is with you. Perhaps you write clean code and you use it to justify your supposed intelligence. If so, you wouldn't even know it. Such is the nature of bias.
