I think that many people who are anti-science, or even just anti-my-pet-theory, have trouble not with the science itself but with their own inability to re-evaluate their position. You might remember a post I made awhile back called Cognitive Disfunction. It was about the inability to accept evidence contrary to one’s own belief regardless of the reason. As an example I used the Plane on a Conveyor Belt episode of Mythbusters. As I thought about it more I came to the realization that the major problem there was an inability to re-evaluate the original conclusion that they reached.
In part the problem arose because of that way that it was worded (which was most likely by design). Here again is the actual description of the problem.
[N]ormally a plane sits on the runway, spins up its engines, moves forwards gets enough air over its wings and takes off. But in this case, the plane is sitting not on the runway, but a huge conveyor belt that is matching the planes forward speed in reverse, and the grand question is can the plane take off? The myth is that it can’t
On first hearing it, the mental image that you might form is one of the plane standing still because the faster it moves, the faster the conveyor belt moves, thereby nullifying it’s forward speed and preventing it from getting any airflow over the wings so it can fly. It just remains stationary. I admit that this was my first impression and I was one of those people who were fooled by the wording.
The breakthrough moment comes when you realize that this conclusion is based on the false premise that the wheels are powering the forward movement of the plane. They aren’t. The forward movement comes from the propellers (or possible the jet), which is independent of the wheels. Therefore it doesn’t matter how fast the conveyor belt moves, the plane will move forward.
I think many of the people who were arguing against the Mythbuster’s conclusion were stuck with their first impression of the problem. Arguments that the wheels didn’t affect the forward movement of the plane weren’t even relevant to them because as far as they were concerned the description said that the plane was stationary, and a stationary plane cannot take off. The fact that you were arguing against that simple premise demonstrated that you didn’t actually understand the original description.
A similar problem seems to affect people who are dead set against the Theory of Evolution. I’ve been in many debates with anti-evolutionists who obviously had a great misunderstanding of how evolution works. For example they would say that mutations can only be detrimental, meaning that natural selection could only allow organisms to survive which couldn’t survive because of the mutations. The absurdity of that proves that evolution is false. Or they would question exactly who it is that is deciding which organisms live or die. Without someone to make that decision evolution simply cannot work. These are obviously profound misunderstandings of how evolution works, but of course from their point of view I am the one that doesn’t understand. And just like the stationary plane they are based on initial misunderstandings that they either can’t or won’t re-evaluate.
