Obesity Denial

It seems that for every established science there is an ideological group who is motivated to deny it. Denialism is a thriving pseudoscience and affects any issue with the slightest political or social implications. Sometimes, even easily verifiable facts can be denied, as people seem willing to make up their own facts as needed.

Denialists have an easy job – to spread doubt and confusion. It is far easier to muddy the waters with subtle distortions and logical fallacies than it is to set the record straight. Even when every bit of misinformation is countered, the general public is often left with the sense that the topic is controversial or uncertain. If denial is in line with a group’s ideology, then even the suggestion of doubt may be enough to reject solid science.

We see this when it comes to the effectiveness of vaccines, the evolution of life on earth, and anthropogenic global warming. A recent Pew poll shows that the campaign of global warming denial has been fairly successful – while the science becomes more solid around the consensus that the earth is warming and humans are contributing to this, the public is becoming less convinced.

“I Reject Your Reality” – Germ Theory Denial and Other Curiosities

Note: This article was originally published in Skeptic magazine. Space limitations resulted in omitting some of what I wanted to say. I’m taking advantage of having a blog to publish the entire article as originally submitted.

On an episode of Mythbusters, Adam Savage was shown a video clip that contradicted his memory of something he had said. He responded, “I reject your reality… and substitute my own.” He was joking. Unfortunately, the world is full of people who reject reality and who are not joking.

James Randi tells a story about a TV program that featured Uri Geller doing his standard trick of bending a key. Afterwards, the program’s host said it couldn’t possibly have been a trick because Uri had “never touched” the key. The host was then shown the recorded program, which proved that Geller clearly had the key in his hands, for two-and-a-half minutes. Instead of admitting having been wrong, the host exclaimed, “Well, that’s not how it happened.”

One of my own ancestors was a pro at this kind of thing. I’ll call her Aunt S (for stubborn). She had once tried tinned sardines, hated them, and refused to ever touch sardines again. One day she came into my grandmother’s kitchen when she was frying up some large fresh sardines a friend had brought her. Aunt S ate some, proclaimed them tasty, then asked, “What kind of fish were those, Mary?” My grandmother told her they were sardines. She protested, “No they weren’t! I don’t eat sardines!”
