Three types of problematic reviewers emerged from our validation process.
We identified three distinct student personas. Lazy Graders select largely the same answer for all questions regardless of whether responses are warranted, or spend minimal time on reviews. Harsh and Happy Graders are students who were unexpectedly strict or lenient on one project compared to others who graded that same project. Misaligned Students consistently rate all their projects significantly more positively or negatively compared to the rest of the class. These personas help us identify which feedback needs re-evaluation to maintain fairness.
