Your evidence is wrong, because I disagree!

By, Adam K. Fetterman
After the Senate passed a bill to repeal the unpopular “Don’t Ask, Don’t Tell” (DADT), it was up to President Obama to sign the bill. He did so on December 22, 2010. This was one of his many campaign promises that he has either completed or attempted to complete. For quite some time, it was uncertain whether this bill would be passed. While many found the DADT policy unjust and prevented dedicated individuals from serving their country, many others opposed repealing it for many reasons. For some it was just plain ignorance and prejudice. Others still thought that it would reduce morale in the military and would be dangerous for those LGBT individuals serving. Presidential candidate John McCain was one of those opposed to the repeal. However, he gave the impression that his mind could be changed by a study showing that a majority of those in the military approved of or saw little problems with the repeal. Indeed, a Pentagon study found just that. McCain rejected the study stating that it was flawed. This seems to happen quite often, but why?

According to research by Munro (2010), when presented with belief-disconfirming scientific evidence, individuals tend to disbelieve the efficacy of the research. That is, when presented with evidence to the contrary of one’s opinions or beliefs, many individuals will reject the evidence. This is what Munro refers to as the scientific impotence discounting hypothesis. Individuals want to believe that they are correct and therefore need to find a reason to discount disconfirming evidence. An easy way to do that is to reject the evidence. This is particularly easy to do when it comes to scientific evidence, as most people do not fully understand scientific methods. This appears to be what happened with the study conducted by the Pentagon. McCain had an opinion and many of his supporters agreed with his opinion. Therefore, it was probably pretty beneficial and easy for McCain to reject the evidence so that he could maintain his opinion. The question becomes, then, could anything change his or others’ opinions on this and other issues? How about in more controversial issues, such as reconciling science evidence with one’s religion?
