We live in a world where everyone is trying to prove they’re better than everyone else. So, it’s no surprise that some folks want to know how their intelligence stacks up to others. The last thing anyone wants is to have an average intelligence. It’s why a lot of us turn to IQ tests to figure out just how smart we are, but these tests aren’t perfect. In fact, some would say that the tests don’t measure an individual’s intelligence with a lot of precision. But you don’t need an IQ test to tell you if you’re smart or not. All you have to do is look for these signs that could reveal you’re smarter than average.
This might be heavily debated but if you’re taller, you might be smarter, too. A Princeton study found that taller children do a lot better on cognitive tests than their shorter counterparts. This indicates that intelligence might be a genetic trait, but the study wasn't able to verify that.
#2. Monogamous Men
You’re not the kind who sleeps around on their partner. We get it! Temptation is right around the corner. For some men, it is ingrained in their biological DNA to “spread their seeds” around. But those who fight the urge to cheat on their partners, and choose to stay in a committed relationship with just one person are generally smarter than your average Joe. They’re acting against historical human ways, which is a huge sign of intelligence. The same does not seem to apply to women and monogamy, according to CNN. "This makes sense because having one partner has always been advantageous to women, even thousands of years ago, meaning exclusivity is not a ‘new’ preference”.
According to research, if you’re a heavy smoker, you probably have a low IQ. The study found that young 18 to 21 year olds who smoke everyday generally have an IQ of 94. Meanwhile, non-smokers who are around the same age have been found to have an IQ of at least 101. But that’s not all! The study was conducted on 20,000 people at the Sheba Medical Center at the Tel Hashomer Hospital in Israel. And while IQ numbers don’t lie, Dr. Mark Weiser, (who was in charge of leading the study) said he’s still unclear whether people who are naturally smarter are less inclined to smoke, or if smoking causes someone’s IQ to lower.
#4. Pointy Chins
Every man is different, but apparently, having a pointy chin might be a sign that you’re really smart. Don’t judge a book by its cover, or in this case, a man by their chin. According to a study that was published in NCBI, people are able to perceive intelligence just by looking at a man’s face, but this doesn't work with women’s facial structures. In the study, researchers used 40 pictures of men and 40 pictures of women. Then, they measured the intelligence of the 80 participants by implementing standard IQ tests. They then proceeded to show these images to other folks who were able to almost accurately guess a man’s IQ just by looking at his facial features. According to this fascinating study, men with longer faces, far apart eyes, larger noses, and pointy chins were perceived almost instantly as being smarter. Best of all? They hit the nail on the head, as researchers claimed their IQ tests ranked high.
#5. BMI of 20 or Less
If you’re not overweight and enjoy a healthy BMI index, then you’re most likely to have a higher IQ than those who struggle with obesity. That doesn’t necessarily mean that obese people have low IQs. But being overweight does have a detrimental effect on your overall health, and yes, that includes your brain! A test was conducted on over 2,200 adults and after 5 years, the study successfully linked obesity with a person’s decline in cognitive function. "The researchers found that people with a Body Mass Index – a measure of body fat – of 20 or less could recall 56 percent of words in a vocabulary test, while those who were obese, with a BMI of 30 or higher, could remember only 44 percent.” This meant that subjects who were extremely overweight reported a higher rate of cognitive decline. Researchers retested the subjects five years later, only to discover that their recall dropped a whopping 37.5 percent. But those who had a healthy BMI “retained their level of recall."
