7 scientific traits of highly intelligent people… This is shocking

2. Swearing

If someone is cussing you out, it may not feel as if they’re super-intelligent, but science says otherwise. In a study published in Language Studies found that people who swear have larger vocabularies (a trait associated with high intelligence) than those who don’t.

3. Risk-taking

A recent study completed in Finland found that individuals who are open to new challenges and who aren’t afraid to take risks tend to be more intelligent. The study used a driving simulation, and they found that participants who made riskier decisions during the test had more white brain matter — an area of the brain associated with cognitive function.
