Here are two nice videos that constitute empirical tests of the efficacy of woo.

The Ouija board study, presented by National Geographic, is a nice example of how a simple experiment, using only blindfolds, can completely trash a widespread (but not very harmful) form of woo.

And from deadstate.org, we have a video in which “Scibabe” tests homeopathic claims:

The Science Babe, or “SciBabe” for short, wanted to expose this practice for the bullsh*t that it is — by gulping down 50 homeopathic sleeping pills. She’s also started a petition on Change.org calling for companies like CVS Health and Walgreens to take homeopathic medicine off their shelves. “People will still buy products from your stores,” the petition states, “but instead they’ll buy products that actually work with proven claims.”

I’ll have more to say about the phenomenon of “science babes” tomorrow.
