I never said people shouldn’t need facts to back up their statements. I am trying to say that there are other ways to make assertions without having to cite peer reviewed studies.

And, that when people get stuck in a mindset of dismissing any idea that doesn’t have a citation to justify it, when subjects come up that aren’t easily studied empirically you end up with a blind spot. In my example the blind spot was infant pain. In my mind, any rational person would look at a crying baby and come to the conclusion that the little baby feels pain. But, if you demanded I bring a fact to back that assertion up, for the longest time I couldn’t provide you with one.
