Is our intellligence heavily relying on our ability to communicate.
This is going to depend on what you mean by "intelligence". We don't have very good definitions. The ways that we
assess intelligence depend on the ability to communicate.
In
Message 4 I commented on the Flynn effect (the rise of average IQ over time). James Flynn, who discovered that effect, does not believe that intelligence rises. Rather, he takes the rise in IQ as an indication that IQ is not actually measuring intelligence.
Many believe that IQ and other measures of intelligence are culturally biased. The wolf boy was raised in the culture of wolves. The ways that we assess intelligence are biased toward our own culture and do not adequately reflect the ways that intelligence would be expressed in a wolf culture.
I guess we are drifting a little off topic for this thread.
