Admittedly, the article defines itself as a list of things which have been labelled as pseudoscience at one point or another, and obviously the lines aren't always clear as some things make the list because of quacks' overenthusiasm and/or twisting of what is a small localised benefit into much more than it is.

Lunar effect – the belief that the full Moon influences human behavior.
If my anecdata does not count, it sure is proven that
