Taking risks connects directly to brain structure in ways scientists only recently discovered. A Finnish study published in PLOS One revealed that individuals comfortable with new challenges and risk-taking possess more white matter in their brains. White matter is the region of the brain associated with cognitive function. This biological difference gives risk-takers a cognitive advantage when processing complex information quickly.
Finnish researchers did a study on 34 young men. They employed a driving simulator game where participants were awarded points for the level of risk they were willing to take. YParticipants who made risky decisions during testing showed significantly higher white matter integrity than those who drove cautiously. Risk-takers showed better-developed neural networks, suggesting taking calculated risks stimulates brain growth.
The findings indicate curiosity and willingness to face challenges promote mental development. This challenges the common assumption that careful deliberation produces smarter outcomes. Instead, strategic risk-taking strengthens cognitive abilities and learning capacity. These results have important implications for education and understanding how brains develop during adolescence.
Intelligent risk-taking combines cognitive ability with willingness to explore the unknown. Whether pursuing adrenaline-pumping activities like skydiving or overcoming nerves to pursue personal goals, smart risk-takers merge their love of learning with the thrill of new experiences. Research on adolescent brain development found that white matter integrity in mid-adolescence predicted risk-taking behaviors measured 18 months later, suggesting this trait develops early and persists throughout life.
5. Deep listening
Highly intelligent people are sometimes the quiet ones in a group, attentively listening. This is not due to a lack of opinions but rather to gather insight and tracking meaning, emotions and non-verbal clues to formulate effective responses. This blends metacognition with emotional intelligence, keeping discussions productive by prioritizing understanding over being right. Skilled listeners monitor their own impulses and refine questions to uncover structure in problems and people.
Deep listening promotes better diagnoses of issues, clearer understanding of perspectives, and fewer miscommunications. It also encourages self-checks like “Do I want to be useful or just be right?”.
6. A Preferences For Cats
A frequently cited study of 600 undergraduates reported that “cat people” scored higher on intelligence measures than “dog people”. While dog lovers tend to be more outgoing and happier, cat lovers are more intelligent. This is not only academically but rather their openness and nonconformity tendencies often linked with curiosity and cognitive exploration. However, these results should be interpreted with caution given the sampling limitations.
Pet preference does not determine intelligence, however, it may reflect broader lifestyle and temperament patterns correlated with cognition. Participants who preferred cats scored higher on an intelligence index in one study, while dog-preferring peers scored higher on liveliness measures. Personality differences may shape environments and habits that favor either quiet study or social activity, not raw ability per se.
7. Swearing (a lot)
Common knowledge suggests that the use of profanity is stereotypically linked to someone who has a limited vocabulary or poor education. However, research contradicts these claims and actually indicates that people with a high IQ swear more often than the average person. A 2015 study published in Language Sciences demonstrated that people who use profanity possess larger vocabularies than those who avoid cursing.
The connection lies in verbal fluency according to researchers. Researchers used controlled word association tests to measure both standard vocabulary and taboo word knowledge. Participants who generated more profane words also produced more regular words starting with the same letters. This correlation reveals that swearing ability reflects overall linguistic skill rather than vocabulary deficits. People who know more words simply know more words of every type, including profane ones.
Swearing predominantly engages the right hemisphere, often called the creative brain. Patients who suffer right-side strokes lose their ability to tell jokes and may stop swearing entirely, despite previously using profanity frequently. This suggests that curse words carry strong emotional significance learned in childhood and stored differently than other vocabulary.
