Joachim de Posada: Don’t eat the marshmallow!

Speaker

Joachim de Posada is a motivational speaker, best known as co-author of the book Don’t Eat the Marshmallow…Yet.

Summary

In this experiment, a 4 year old child is presented with a marshmallow. If they can stay in the same room as the marshmallow for 15 minutes without eating it, they get a second marshmallow. 2/3 of children ate the marshmallow, while the remaining third were rewarded for delaying gratification. This experiment can be used as a predictor of future success – all of the children who delayed eating the marshmallow were successful at the age of 18. The others were less successful, with lower grades, poorer relationships, and less had plans for future or entry to university.

Joachim repeated the marshmallow test in Columbia. He wanted to see if Hispanic children acted the same way and also found 2/3 of children ate the marshmallow. One girl was interesting – she hollowed out the inside of the marshmallow and ate that, but still left the outside intact (so it looked like she hadn’t eaten it).

My Thoughts

Not the greatest talk – about Joachim taking an experiment and repeating it in a different country. I was also not left convinced that such a simple experiment would predict success – it seems like there would be too many variables. Rather than delayed gratification, it may show the child’s ability to comprehend that 2 marshmallows is more than 1, and understanding of the experiment. Again, the ones who understand the experiment at a younger age are probably more likely to be successful but they would also learn more about delayed gratification as they get older.
