Do you guys think human society is more complex, or less complex, than an individual human brain?
To be honest, I don't know. Complexity is the science of chaos. We are mapping the brain and can actually program computers to mimic thought to a degree. The signal to noise ratio is higher in the brain than society. Society is really pretty simple if you filter out statistically insignificant error. I prefer to think of us as family. After all, we all evolved from the same ancestors. We're just a very dysfunctional family.
"The signal to noise ratio is higher in the brain than in society"
What makes you say that? Also, what do you mean by "signal" and "noise" with respect to each? Further, what are you referring to when you say statistically insignificant error?
