What is it about?

Feedback is used by policymakers all the time to improve the judgements of individuals. Yet we show that when judgement is about one's own self, people will update their judgements in an irrational way and will not take the whole information in the feedback into account. They will disregard the information about the competition and focus on "irrelevant" aspects of the feedback.

Why is it important?

Educators, managers, and politicians can use feedback to improve the decisions of students, staff and citizens. Yet they should know that some forms of feedback may not work as well as other forms. To design working feedback systems, policymakers should know about the biases people posses in their judgements.

Perspectives

This was a very interesting project for me personally - since working with feedback is a ubiquitous part of my daily work life as an educator. Knowing that students change their judgements in certain ways that are not rational following my feedback makes me to rethink what I expect of them and how I should deliver feedback.
