Inference, Experience, and Genetics

Some or many lessons learned through experience may be genetically encoded over time and this may be why infants can draw many valid inferences before they have any experience. Cf. Nicholas Wade, In Tiny Worm, Unlocking Secrets of the Brain, NYTimes (June 20, 2011):
Dr. Bargmann sees the arrangement in evolutionary terms. “The more reliable a piece of information is, the more it will be shifted into the genome,” she says. That way, an organism does not have to risk learning what is good or bad; the genes will dictate the right behavior by wiring it into the nervous system. Worms are wired up to know that diacetyl means good eating.

And the primary and secondary wiring of the worm's little brain is constantly being rewired by a network of neuropeptides. Id. Now there's learning from experience for you, learning that becomes instinctive and reflexive!

This research touches on a thesis about factual inference. Almost all students of factual inference agree that "experience" in the form of generalizations plays a key role in inference. Yet in many instances the persons drawing the inference have not themselves had the experience they invoke. One must assume that many generalizations are culturally transmitted, perhaps genetically transmitted, and perhaps transmitted by both methods.
