For example, I might compare the benefits of my current job with the benefits I had in a previous job. I would also be comparing what I bring to the job, such as my level of effort, knowledge, or inputs. If both you and your referent have low inputs and low outcomes or high inputs and high outcomes, no tension should be created. However, if you have low inputs and high outcomes and your co-worker has high inputs and low outcomes, you might have some tension. I have known people who made themselves miserable comparing themselves with a sibling, a friend, or a parent—people who otherwise should have been very happy.
