Results showed that some people showed more wisdom than others. But this difference between some people’s wisdom was smaller than the difference between wisdom in particular situations.
Research also showed that people display more wisdom when they are with other people.
Furthermore, keeping a diary also improves wisdom levels. Perhaps a diary helps to improve self-reflection.
Researchers also checked gender, education level, and age. It turned out that only age impacted the level of wisdom. Neither gender nor education level had an effect.
The scientist, Grossman, also stated that measuring wisdom with a single questionnaire item is unreliable. Because a person’s wisdom differs so much from one situation to another, Grossman said you’d really need to test someone on at least nine situations to know their levels of wisdom.
