Great Myths about Human Behavior

From 50 Great Myths of Popular Psychology, which I just read, comes some myth-busting that will make you happier. Turns out, many of these myths and misconceptions err on the side of assuming people are worse than they are. Below is the truth.

1. We use more than 10 percent of our brains. This one is a big pet peeve of mine. Up to 60 percent of people believe that we only use 10 percent of our brains. No, we use it all. We know this because we have a ton of cases where someone gets some specific part of their brain mauled and subsequently has trouble performing a certain task. And because we can map the brain and watch it light up when people think about different things. And because the authors trace the root of the myth to the 1936 saying "People only use 10% of their potential", a more plausible but still made-up statistic.

2. Our teen years aren't that turbulent. Studies show that only about 20 percent of teens undergo the turmoil attributed to the stereotype of their age. Most teens report generally happy moods and harmonious relations with their parents.

3. Neither are our mid-life crises, a standard movie cliché that occurs much more often in fiction than in real life.

4. Similarly, "Empty Nest Syndrome" is also an uncommon disorder, and not to be expected as a rule.

5. Amnesia is also rare. (And the loss of past memories particularly so; most amnesiacs have trouble forming new memories.) That's the good news. The bad news about amnesia is, if you have it, a second bump on the head will not cure it. Hard knocks to the head, as a rule, only make things worse.

6. Modern society is not that stressful. The idea that living in modern, Western society is more stressful than living in undeveloped countries is a myth. Turns out, it's very stressful to live in a poor country.

7. Men don't think about sex an average of every 7 seconds. I've heard this one a lot over the years. It's an urban legend, which should be obvious, since it sounds tremendously impractical. It would mean that if I gave a half-hour presentation at work, for example, I would have thought of sex 257 times during it. Quite a feat.

8. Men and women are both from Earth. The authors break down the idea that men and women (Mars & Venus) communicate in totally different ways into several more specific questions. They find that the differences, while some exist, are mostly statistically insignificant.

9. Many childhood victims of sexual abuse grow up well-adjusted. There's a myth that childhood sexual abuse invariably leads to psychological problems as an adult, but thankfully, while this does happen in some cases, it is far less common than we might think. Fortunately, children are much more resilient than we tend to give them credit for.

10. Subliminal messages aren't real. They don't work. If they did, advertising companies would try to use them, I'm sure, but they don't. Our brains are smarter than that. Sorry, plot of Josie & the Pussycats.

11. Crimes don't increase during the full moon. Nor does mental illness, etc etc. Can you think of any easier urban legend to measure and debunk? This one has been straightforwardly disproved time and time again but refuses to go away.

Turns out when we stop relying simply on "common sense" and stories we see on TV, and instead look at decades of hard research and statistics, we find most of humanity's not that bad, after all.
