A recent trend in cable television is paranormal investigation shows. For example, the SyFy channel has Ghost Hunters and A&E has Paranormal State. The point of these shows is to investigate claims of the paranormal and then confirm or debunk them. While certain shows do a fairly good job of at least “trying” to debunk the claims, others make no clear attempt. For instance, many, if not all, of these shows feature a time of “investigation” in which the main “characters” try to communicate with the spirit world. They do so by asking the “ghosts” to make a noise or make themselves appear. Usually they will come up with some sort of noise or evidence and conclude that, “indeed, there is a presence!” The first problem here is that, in order to properly debunk such events, one must not believe in them in the first place, or at least have some education in explaining psychological or natural experiences. However, the main issue is that a truly skeptical person will take the evidence of a random noise in response to a question as chance occurrence that is more likely to be explained statistical randomness. One the other hand, a paranormal believer would dismiss that event as chance and explain it paranormally.
This is what is known as the conjunction fallacy. According to Rogers, Davis, & Fisk (2008), indeed those who believe in the paranormal, are more susceptible to the conjunction fallacy than non-believers. Furthermore, they found that those less educated in math, statistics and psychology were more susceptible as well. Therefore, when two not-so-rare events occur (i.e. talking and a bump in the night), paranormal believers make the error in concluding that both events occurring simultaneously was too improbable to be coincidence. Based on previous findings, Rogers and colleagues suggest that this happens because those that believe in the paranormal have less understanding of chance and randomness. In closing, it is obvious that these shows are for purely entertainment value and most people would not tune in if they didn’t find “evidence” of the paranormal. However, it does seem troublesome to perpetuate a lack of rational and logical reasoning skills.
