Report, if you have a problem with this page“ The first finding that jumped out at us was that it is possible to learn too much ! In the tournament, investing lots of time in learning was not at all effective. In fact, we found a strong negative correlation between the proportion of a strategy's moves that were INNOVATE or OBSERVE, as opposed to EXPLOIT, and how well the strategy performed. Successful strategies spent only a small fraction of their time (5-10%) learning, and the bulk of their time caching in on what they had learned, through playing EXPLOIT. Only through playing EXPLOIT can a strategy directly accrue fitness. Hencem every time a strategy chooses to learn new behavior, be it through playing INNOVATE or OBSERVE, there is a cost corresponding to the payoff that would have been received had EXPLOIT been played instead. This implied that the way to get on in life was to do a very quick bit of learning and then EXPLOIT, EXPLOIT, EXPLOIT until you die. That is a sobering lesson for someone like myself who has spent his whole life in school or university. ”
