Yeah, but it's an important point that taking risks without a model can lead to solutions that would not be found otherwise. Suppose there are ten options for survival and 100 people who are under threat. If they try to develop a theory and all fail, and do not act without hope of success, then they all die. If they develop a theory and follow it, and it is wrong, then they all die. But if at least one option is correct, and they simply try them at random, disagreeing with each other, then about ten people will survive and pass on their genes and/or knowledge.

People are not 100% rational, and being 100% rational is not evolutionarily optimal.
