A new paper argues that using behavioral economics to ease families’ fear of change could help convince them to switch up their children’s routines, reports The Atlantic.

While few question the scientific evidence supporting later start times, many parents and administrators argue that starting school later isn’t the best solution to kids’ sleep-deprivation problems, citing practical concerns. They wonder what later school end times would mean for sports and after-school activities, for example, and how much additional money districts would have to spend on transportation. Because many districts stagger their transportation in order to use the same buses for all of their students, pushing back middle and high-school start times could mean paying for more buses.
