You get what you give: children's karmic bargaining.

Do children believe in karma - the notion that life events occur to punish or reward our moral behavior? In three experiments, we investigate 4-6-year-old children's willingness to endorse and engage in the practice of performing good acts in order to secure an unrelated future desired outcome, so-called 'karmic bargaining'. Most children agreed that performing a morally good social behavior, but not a morally negative or morally neutral non-social behavior, would increase the chances that future desired outcomes would occur, in both first-party and third-party contexts. About half of children also engaged in karmic bargaining behavior themselves. We conclude that a belief in karma may therefore reflect a broad, early-emerging teleological bias to interpret life events in terms of agency, purpose, and design.
