Extrinsic Incentive Bias

Extrinsic incentive bias is the tendency to attribute more more power and influence to external incentives (such as physical or monetary rewards) than to internal incentives (feeling good about oneself), especially when other peoples's incentives are being considered and judged.

An example might be a worker thinking "I'm working overtime because I am dedicated to my job but my co-workers are just doing it for the overtime." This attribution may be true or it might be false, but the extrinsic incentive bias is highlighted by attributing external incentive motivations for others while attributing internal incentive motivations for themselves.
