On top of the hour: Preference for scheduling and starting tasks at the beginning of the hour

Choosing when to start tasks can be an important aspect of task management in daily life. Do people prefer to start tasks at the beginning of the hour, that is, using clock time as a cue for their scheduling preferences? A first study showed a strong preference to start tasks on the hour, even in scenarios involving a cost to starting on the hour, in scenarios involving no other people, and across several forms of start preference measurement. A second study examined reports of real-life tasks: Participants identified next-day tasks ahead of time and then reported on these exact tasks 2 days later. Starting tasks on the hour was not linked with benefits for individual task progress, but starting a higher percentage of tasks on the hour over the day was linked with judging the day overall as having been spent more efficiently. In sum, these studies identify a preference for scheduling and starting tasks on the hour but show mixed evidence that this preference is beneficial for task achievement.
