That there are still significant audiences for those who promote obvious nonsense – from creationists like Ken Ham and Ray Comfort to anti-vaccination lunatics like Jenny McCarthy and Robert F. Kennedy Jr. or proponents of crazy political notions (take your pick) – is testament to the fact that the human brain is a product of evolution and that evolution does not necessarily produce optimal solutions. That, is the human brain has significant weaknesses.
Scientific methods of investigation have been specifically designed to compensate for the shortcomings of our brains but they are not able to compensate for the fact that some people choose to trust bullshit more than they trust science.
It comes down to values: reason or faith? Pick one.
This is old hat to those of us who have been trying to address young earth creationism for some years but those who have more recently become interested in the subject might find it useful.
Ken Ham‘s Answers In Genesis organization has a Statement of Faith. All who are involved with that organization, whether as staff or as volunteers, including Ham’s pet scientists, are required to agree to this statement.
The Dr. Oz episode* in which he endorses applied kinesiology (not to be confused with kinesiology, which is a legitimate study) to diagnose allergies was re-run again today. Oz appeared to completely buy into it, even though he says he has no idea how it works.
Well, if he consulted with a knowledgeable skeptic or even did a simple internet search, Oz would learn that it’s got a lot to do with the ideomotor effect. He could also quite easily discover that applied kinesiology has been subjected to proper scientific testing and has been found to be no better at diagnosing allergies than random guessing.
