If these 11 things apply to you, you may be smarter than you think

Bright, clever, witty and knowledgeable are just some ways people define smartness. Some might even throw the word genius into the mix. Doctors have their own definitions, too. A genius is traditionally someone with extreme intellectual skill with high IQ test scores, says Judy Ho, PhD, a triple board-certified clinical, forensic and neuropsychologist, and author of Stop Self Sabotage. Although, she says these tests don’t always offer the full-picture because some genius skills, like creative problem-solving, are harder to measure.

Defining smartness, as well as genius, might not be clear-cut, but overall, most people agree that smart people have a high level of thinking. You might be one of them if these things apply to you.

A study published in the Journal of Human Resources suggests that firstborns might have a “mental edge” over their younger siblings as they tend to have higher IQs. According to researchers, this is because parents often offer older kids more mental stimulation, they breastfeed, and they take fewer risks like drinking and smoking during the first pregnancy. So smart older children aren’t necessarily a result of genetics.

Research in the journal Intelligence suggests that geniuses, or people with higher IQs, report more mood and anxiety disorder diagnoses than the national average. Dr Ho says this could be because geniuses often overthink everything since they try to achieve perfection. This level of high self-reflection, plus a more neurotic personality, links to a higher risk for anxiety and other mental health distress, according to Dr Ho.

Anyone who is a bit different is also susceptible to suffering from social challenges, according to Catherine Franssen, PhD, a professor of psychology and director of neurostudies at Longwood University. “That includes those who are different because of something that seems like a positive trait, like a genius,” Dr Franssen says.

Many geniuses are physically active, according to Dr Rahul Jandial, PhD, the author of Neurofitness, and a dual-trained brain surgeon and neuroscientist. “There is clear evidence showing physical activity sharpens the mind and allows for unique connections in concepts and thoughts,” Dr Jandial says.

This boost in brain function is because stress of all kinds supplies neurons with more blood, so they can grow, connect, and enhance the brain, Dr Franssen adds.

A study from the London School of Economics and Political Science suggests that people who tend to go to bed later have higher IQs. The researchers believe this is because of evolution. Nighttime meant danger, so our ancestors who chose to stay up and out late instead of sleep needed to be smart.

Dr Franssen adds that working late or outside the typical nine to five workday allows for more innovation and creative thought as there are fewer interruptions or demands, and different expectations. “A genius might choose to work at odd hours to improve creative thought,” she says. “Or more time spent on creative thought at odd hours might develop genius.”

Being adaptable means having the intelligence and awareness to see things from a fresh perspective, according to Dr Jandial. “That means being able to see connections or solutions that others can’t,” he says. New problems and challenges require new, novel solutions, something smart people and geniuses are comfortable with, Dr Ho adds. Psychologists also say adaptation requires other cognitive processes, too, such as reasoning, perception, problem-solving and memory.

If you appreciate “sick” jokes, you might be a genius. According to a study published in the journal Cognitive Processing, your reaction to dark humour may indicate your intelligence. The psychologists defined dark humour as, “humour that treats sinister subjects like death, disease, deformity, handicap or warfare with bitter amusement and presents such tragic, distressing or morbid topics in humorous terms.” Fans of these jokes might have higher IQs along with less aggression. Researchers claim processing dark humour jokes is more work for your brain.

Practising music at a young age helps develop young minds in a few ways. One 2018 study in the journal Frontiers in Neuroscience found that kids who took structured music lessons tested higher on quizzes for verbal intelligence, planning and inhibition. Another study in the Journal of Psychological Science found music lessons for 4- and 6-year-olds enhanced their verbal intelligence.

Check out these 21 hidden benefits of music.

Being judgmental isn’t the best trait to have, but a study in the Journal of Experimental Psychology: General suggests that smart people may be more prone to stereotyping thanks to their ability to detect patterns.

Creativity is thought to be a hallmark of most geniuses, according to Arif Dalvi, MD, MBA, of the Palm Beach Neuroscience Institute. If you’re messy, this could be a sign of creative genius. A study from the University of Minnesota asked participants to come up with atypical uses of a ping pong ball. The 24 people with neat rooms had less creative responses than those with messier rooms.
