In this experiment, volunteers were asked to unscramble a series of sentences. Some participants were presented with sentences containing words related to time (e.g., "clock" and "day"), whereas others' sentences contained words related to money (e.g., "wealth" and "dollar").

But Mogilner wanted to test the effect in the real world, seeing how people actually spent their time. So her research team approached people going into a caf
