Given the current COVID-19 scenario, this is the right time to measure the mental strength of companies and individual members.
Here is a good video to understand why mental strength matters.
While it is fun to make such adorable videos, that is not the core reason for this experiment. The researchers studied these children years later as a follow-up study.
In follow-up studies, the researchers found that children who were able to wait longer for the preferred rewards tended to have better life outcomes, as measured by SAT scores, educational attainment, body mass index (BMI), and other life measures. A replication attempt with a more diverse sample population, over 10 times larger than the original study, showed only half the effect of the original study. The replication suggested that economic background, rather than willpower, explained the other half.https://en.wikipedia.org/wiki/Stanford_marshmallow_experiment
There is one plausible reason why the children who were able to delay gratification were able to go well in life. These children were able to say no to alcohol, drugs, and sex during their college days.
That brings us back to this topic. I believe the lockdown is the marshmallow test for the entire world. Lockdown over a long period is stressful. This mental model helps me go through the stress of this lockdown much better.
Hopefully, we all come out of this fine.
