Just try and convince me humans have not already crossed the same threshold.
In 1995 the Murder rate in the US was 8.2 per 100k with a population of around 260 million. In 2012 the Murder rate in the US was 4.7 per 100k with a population of around 313 million. In 1980 the rate was 10.2 with a population of 225 million. Shall I now correlate internet usage with troll activity, and erroneously conclude that internet trolling reduces the murder rate? Or should I conclude the Humans are the opposite of rats, and they become calmer in over populated situations? Also Erroneous.
