The limit to one's intelligence


Recommended Posts

The brain works by making neural connections, to make more connections, use it more. Making these connections is easier when your brain is still growing. Some people find it easier to make new connections than others. There may be a maximum amount of connections it is possible for one head to hold, I imagine this would be lots.

With the onset of puberty, the number of neural connection actually gets reduced. The brain starts pruning it's connections, yet we get smarter.


So it si not simple the number of connections in the brain, but the quality of those connections (what they connect to and the organisation of them).


So, to get smarter, we first need to increase the number of connection, and then prune them, leaving the ones that are necessary.


We can still do this later in life, but at a much reduced rate (and so it is harder to learn new things). If we could "engineer" our brains so that we could make and break these connections at the same rate we did when we were children, then we might be able to dramatically increase human intelligence.
