Soft Skills

300Cognitive skills are what schools and testing tend to measure. Cognitive skills are things like attention span, memory, logic and reasoning, and processing speed. If you have strong cognitive skills, you tend to do well in school. You also tend to get a lot of positive validation.

Having strong cognitive skills is great and can help a person be successful in life, however, some people think non-cognitive skills, or soft skills are as important or more important for a person to live a good, successful life. Standardized tests are a good way to measure cognitive skills, but grades are a better predictor of success in life, because earning good grades involves more of a combination of cognitive and non-cognitive skills.

Delayed gratification is a soft skill that greatly impacts a person’s ability to manage their finances. A person without delayed gratification wants what they want and they want it now. A person without delayed gratification tends to be more impulsive, and may be more likely to do things that they later regret.

The marshmallow experiment that was conducted at Stanford University was a study in delayed gratification. Lydia Dallet has written about how delayed gratification can impact a person’s financial success. This American Life did a Back to School show and Ira Glass talked to Paul Tough about schools and soft skills (at 13:45). Paul Tough is the author of “How Children Succeed: Grit, Curiosity and the Hidden Power of Character“.
