It’s funny; smart people tend to sell themselves short while those with slightly less-than-ideal IQs overestimate themselves. This is a real phenomenon known as the Dunning-Kruger effect, the result of a Cornell University study. If you’re not too sure about your own brainpower, then have a look at these subtle signs that you’re actually a genius waiting in the wings.
You took music lessons
Studies in 2004, 2011 and 2013 found that children of varying ages had IQ rises after music lessons compared to kids who had no music lessons at all. However, interestingly, the 2013 study suggested that the kids that were most likely to take music lessons were already high-achievers. Basically, this means that instead of boosting intelligence, music lessons may only enhance preexisting cognitive differences.
You’re the oldest
We’ve already reported on this, but as a recap: the first-born children get an IQ boost from having to teach their younger siblings. Receiving undivided attention also benefits the IQ.
Dr Julia Rohrer said to the Daily Mail: “One theory is that following children “dilute” the resources of their parents.”
“While the firstborn gets full parental attention, at least for some months or years, late-borns will have to share from the beginning.”\
This isn’t intended as fat-shaming, but studies have found that adults who weighed more were more likely to score lower in intelligence tests. The studies also indicated that children who scored lower on verbal and nonverbal tests at age 11 were more likely to be obese by their 40s. Another link was that a lower IQ contributes to a higher BMI. These authors said that environmental factors came into play, as the BMI/smarts relationship was mediated by socioeconomic status.
You have a cat
Okay, dog lovers, hold on a sec. A 2014 study of 600 college students found that “dog people” were more outgoing than “cat people”, but the same test found that the cat people scored higher on the part that measures cognitive capability.
