Well that's a pretty confusing article. As far as I can see all it points out is that the guy had theories claiming cancer and heart-disease were caused in part by certain mindsets. Then it goes on to mention how these theories were apparently very successfully tested by him, by preventing people from falling sick. And so the claims he made are apparently supposed to sound "ridiculous" enough to the reader to discredit his work? Strange.
