“In every job that must be done, there is an element of fun. You find the fun, and snap, the job’s a game!” So says Julie Andrews’ character in the Disney film Mary Poppins before she launches into the famous musical number “A Spoonful of Sugar.”

In this episode of Choiceology with Katy Milkman, we look at the science behind the intuitive strategy of making difficult or boring things easier by adding that “element of fun.” But while Mary Poppins was focused on making the tedious task of cleaning a room a bit more enjoyable, you’ll see that this approach isn’t limited to housework.

You’ll hear Nancy Stahl’s dramatic story of a life-threatening medical event. Her prognosis was grim, but thanks to grit, determination, and some pioneering work in gamifying rehabilitation by Professor Lynne Gauthier, Nancy made a remarkable recovery.

Next, Dan Ariely recounts an incredibly difficult long-term treatment that he was able to endure and complete, thanks to a strategy known as temptation bundling (a term coined by Katy Milkman through her research into the phenomenon).

Finally, Ayelet Fishbach joins Katy to discuss research into myriad ways that adding enjoyable elements to difficult or tedious tasks can improve outcomes in everything from math education to exercise to job satisfaction.
