Sitcoms often take advantage of a very simple fact about human psychology to make us laugh. The set-up will go something like this: main character tells their partner: “I would never compromise my ethical principles for money!” Then that very same character is offered an opportunity to compromise their ethical principles for money…and they take it.
The joke is not just about hypocrisy but also about the main character’s complete unawareness of his or her hypocrisy.
Watching this we might assume it isn’t intended to be diagnostic of human psychology; rather it’s just a way of making a joke at the expense of the main character. But really it’s a perfectly realistic example of how people avoid the truth about themselves.
In a recent paper in the Review of General Psychology, Sweeny et al. (2010) outline the three main reasons that people avoid information:
- It may demand a change in beliefs. Loads of evidence suggests people tend to seek information that confirms their beliefs rather than disproves them.
- It may require us to take undesired actions. Telling the doctor about those weird symptoms means you might have to undergo painful testing. Sometimes it seems like it’s better not to know.
- It may cause unpleasant emotions.
You can see all three of these motivations in play in the sitcom example. Weighed against them—motivating us to find out the truth—are all the reasons you’d expect like curiosity and hope for positive information. Whether we try to find out the truth or avoid the information depends on the following:
- Expectation. Most obvious and maybe most powerful. The more we expect bad news, the more effort we make to avoid it.
- Lack of control. Less obvious but it explain a lot. When we feel we have less control over the consequences of information, we are more strongly motivated to avoid it. Like when you could be getting news about a life-threatening disease. Because there may be little you can do about it, it may be better not to know.
- Lack of coping resources. When people feel they can’t handle distressing information at the moment then they’re more likely to avoid it.
- When the information is difficult to understand. The harder it is to interpret information, the less we want to know about it.
So people often do their best to avoid learning about themselves and sometimes this makes perfect sense. For example genetic testing may tell you that you have an increased risk of atrial fibrillation after the age of 70. Is that useful information or just one more thing to worry about? If there’s nothing you can do about it then perhaps it’s information that only worsens your quality of life.
Other times we hurt ourselves by avoiding information. Like when we refuse to get that strange mole checked out and end up delaying treatment for cancer.
The trick is to know which information to avoid and which to seek out. But we can’t know this without knowing what the information is. But once you’ve learnt the information you can’t unlearn it. It’s a problem.
I offer no answers, merely to point out that avoiding information is a much more rational strategy for dealing with the complexities of a frightening world than it might at first seem. There’s a good reason we value the innocence of youth: when you don’t know, you’ve got less to worry about.
When we laugh at the hypocrisies of a sitcom character, it’s also a laugh of uncomfortable recognition. As much as we’d prefer to avoid the information, in our heart of hearts we know we’re all hypocrites.
