Sibling Rivalry
Posted by Alex Palmer on February 19, 2008This American Life had a segment a few weeks ago about a mother fed up with the fighting between her two daughters: 12-year-old Kennedy and 5-year-old Zadie. Zadie pesters Kennedy for attention, which the older sister finds annoying, and what begins as quick snaps at each other turns into all-out bickering, leading Lisa, their mom, to intervene.
The way Lisa went about fixing this tension which plenty of families deal with offers some pointers about employee motivation and incentives. Seeking to encourage a more harmonious relationship between the two, Lisa begins a "behavior modification experiment" using monetary incentives. She pays Kennedy $100 over a month to play with her sister an hour every day. Lisa convinces Kennedy that it's an experiment on her sister: they're seeing if she can get Zadie to get less worked up when her overtures for attention are ignored. In fact, Lisa explains, it's an experiment on both girls.
