Jonah Lehrer of The New Yorker argues for the existence of a common phenomenon in science called “the decline effect”, which is that large effects observed in an experiment tend to become smaller and smaller in subsequent replications.

Sokal’s Hoax – the posterior version. Embryologist John McLachlan has proposed a new form of reflexology – on the buttocks. As a treatment technique, he suggested applying “gentle suction” on parts of the buttocks that are associated with different areas of the body. He sent an abstract of his theory to the Jerusalem International Conference on Integrative Medicine, which was accepted. In a letter to the British Medical Journal he later explained that this had been a hoax intended to expose the absurdity of alternative medicine. In a talkback comment on the Israeli news site Ynet, conference organizer Avraham Fried wrote1 that the actual problem in this case was McLachlan’s willingness to lie and infringe the scientific norm of trust to make his point, and he resented that the BMJ did not ask for his response.
