There is ongoing debate about whether extrinsic rewards undermine intrinsic motivation. Some research has found that extrinsic rewards like money can decrease intrinsic motivation for an activity. However, other studies have found that rewards do not always undermine motivation and that factors like how the rewards are administered and an employee's sense of competence can impact the effect on intrinsic motivation. Overall, the research in this area has produced mixed results, and more work is still needed to fully understand how extrinsic rewards impact intrinsic motivation in different contexts and situations.
