Epiphanies tend to strike like lightning bolts—sudden flashes of insight that reshape how a person sees the world or themselves. Next, they held a “legacy workshop” with 149 MBA students from a diverse European business school, asking them to reflect on the legacy they would like to leave. What they found is that a kind of playful mind wandering sometimes known as “problem-solving daydreaming” is especially good at inducing powerful epiphanies. The researchers defined this problem-solving daydreaming as “imaginatively engaging with [one’s] psychological tensions and focusing steadfastly on resolving them.” They reported their findings in a new paper in the Journal of Management. “Compared to working on problems in a more deliberate, formal manner, problem-solving daydreaming can be especially freewheeling and playful.”Not everyone is prone to problem-solving daydreaming, the team found.
