VIA NEGATIVA IN INTELLIGENCE: GENETIC LOAD CAUSES STUPIDITY
A somewhat popular post from ’12 that made the rounds. It follows my understanding that the size of the brain largely determines its capacity for intelligence and that the accumulation of defects causes stupidity, rather than, intelligence being a specific modification. This would mirror the data in that intelligence seems to be produced by many sequences. Or conversely, that many sequences can inhibit intelligence.
