"No one knows what science doesn't know."

This sort of anthropomorphic bias leads to conceptual errors. 'Science' is the method of acquiring knowledge and the collection of acquired knowledge to which the method is rigorously applied. It is incapable of knowing anything independently of what individuals know; in fact, it can't know anything at all without some knowing individual to practice it. And to be sure, we can know things 'science doesn't know': we know we are in love, that we are happy or sad, that we played baseball for the first time when we were 6 years old at the park in Glens Falls, etc.
