The other problem with right I forgot to mention is that Rigor generally means: 1: Refusing to make a firm affirmative statement on an issue, when that's what people want 2: Correcting what you have claimed in the past, which makes you look gullible and indecisive With the example of bloodletting, people wanted to believe a doctor knew how to cure them, and once somebody had done bloodletting even if they had doubts later, they would look like fools if they convinced people they had been harming their patients all along. It's easier and often more rewarding to be a fraud.
