No, it's not quite Bayesian.
Somehow I feel like we've hashed over this before, but should "Bayesian" be normative? The word seems to have a rather idiosyncratic usage around these parts, and its choice as the name for Doing Rationality Right seems to come from a silly historical accident (Eliezer happened to have a silly conversation with someone about probability, and thus associated wrong thinking with "frequentist").
The use may be somewhat idiosyncratic, but the point stands. Bayes' rule is correct, provable from basic axioms of probability.
The "naive" scientific method (advocated in the clip) doesn't account for probabilistic evidence. Even the slightly more sophisticated "statistical significance"/hypothesis testing method doesn't do it right.
Alt-rockers They Might Be Giants explain/advocate empiricism in a record aimed at young children.
No, it's not quite Bayesian. The bridge ("A fact is just a fantasy, unless it can be checked") is more or less simply wrong. Still, I find the fact that the Ancient Art of Rationality is getting play at all pretty exciting. What do you all think? And what can we do to get more rationalist -- or even proto-rationalist -- ideas to youngsters?
