Natural selection’s trial-and-error process allows improvement without anyone understanding or guiding it. The same can apply to how we learn. There are at least three kinds of learning that foster evolution: memory-based learning (storing the information that comes in through one’s conscious mind so that we can recall it later); subconscious learning (the knowledge we take away from our experiences that never enters our conscious minds, though it affects our decision making); and “learning” that occurs without thinking at all, such as the changes in DNA that encode a species’ adaptations. I used to think that memory-based, conscious learning was the most powerful, but I’ve since come to understand that it produces less rapid progress than experimentation and adaptation. #principleoftheday#
