What does growing grit mean? Are there ways to learn how to develop grit?

Growing grit means that you can learn to have grit. Grit is not fixed but is changeable, and you can grow and adjust grit over time.

Growing Grit

All behavioral traits have contribution from genetics and from the environment. When a trait changes rapidly in a population over time, this suggests environment is the major cause, since genetics hasn’t had the time to change much.

  • The average male height increased from 5 feet 5 inches in 1850 to 5 feet 10 inches today. Since our genetics haven’t changed much since then, environmental influences like nutrition are responsible.
  • The Flynn effect finds that the average IQ today, calibrated to 1900 standards, would be somewhere around 130. Our brains aren’t necessarily biologically smarter – better, faster education may be responsible.

Duckworth tries to apply this logic to show that grit has some portion due to environment and is thus malleable. (Shortform note: Because if grit were purely genetic, the book would be self-defeating – you either have grit or you don’t! Time to go home.)

In unpublished twin studies, the heritability of perseverance is estimated to be 37%, and passion 20%. Supposedly, the rest of the contribution is from the environment. This show how growing grit works.

Also, in a survey of US adults, grit rises steadily over age:

Here are possible explanations for this:

  • Maturation could be genetically programmed – evolutionarily, grit may not be as beneficial in early years when seeking mates, and may be more helpful later when caring for a family.
  • Older people could have endured more hardship throughout their lives (e.g. by surviving through World War 2 and the Cold War) and thus trained grit.
  • Maturation happens naturally over time as people learn that grit is a successful strategy for accomplishing goals, and that the opposite – quitting plans, shifting goals, starting over – leads to failure and is unsatisfying. Furthermore, life experiences – like getting a job, having children, caring for parents – require us to mature and adopt more grit.

Because we don’t have longitudinal studies of grit, we can’t distinguish between these explanations, but the third is Duckworth’s favorite. Anecdotally, people change when new expectations are thrust upon them – imagine the teen who sleeps in daily, but then enlists in the military and is punished for waking up past 6AM. Grit can be grown, and you can learn how to develop grit.

Carrie has been reading and writing for as long as she can remember, and has always been open to reading anything put in front of her. She wrote her first short story at the age of six, about a lost dog who meets animal friends on his journey home. Surprisingly, it was never picked up by any major publishers, but did spark her passion for books. Carrie worked in book publishing for several years before getting an MFA in Creative Writing. She especially loves literary fiction, historical fiction, and social, cultural, and historical nonfiction that gets into the weeds of daily life.
