Hyper-specialization in a skill or behavior may develop asymmetric neural circuits as a trade-off.

“And that's what happens when you take young kids and you shape them around a certain behavior, academic or or athletic. So, it's easier to look at those examples and say, "Oh, yeah. I don't want to deal with that." And so let's demonize them. I think we should celebrate those people if that's what they genuinely wanted. And we should pay attention to the fact that they became asymmetric in their wiring literally. And most of us probably don't want that or aren't willing to make those sacrifices.”
