I don't think it is just bias, as if changing a setting somewhere would fix it. There's no easy fix, like the pill in Limitless, if that's what you are thinking. It is more an energy management issue. The human brain consumes 20% of our energy intake if we are resting. And about 28% of our energy intake if it is performing some effort. And all this work also generates waste, which needs to be moved to the blood and this takes time.
