This project aims to understand individuals' preferences for information about feedback on their own performance. In particular,
our goal is to learn how preferences over information about own performance are shaped by the presence of strategic incentives, subjective judgement by others and revelation of one's feedback to others. We will then also test the differences in these preferences by gender and its implications for belief formation about one's own performance.

Experimental Details
The treatment conditions that we will implement are:
1) Presence or absence of the public versus private feedback
2) Presence or absence of extreme subjective judgment from others.
3) Presence or absence of strategic incentives to be chosen to be partnered with.
We test for the impact of these treatments by gender of the partcipants on their choice of more versus less informative feedback.

Primary Outcomes
Primary Outcomes (end points)
-Choice of more informative feedback versus less informative feedback
-Prior and posterior beliefs about one's own performance in a task. (that is, probability with which participants think that they are in the top 50% of the performance distribution)

Secondary Outcomes
Secondary Outcomes (end points)
1) Beliefs about one's partners ability in the task. (that is, probability that their partner is in the top 50% of the performance distribution)

Experimental Design
Experimental Design
First, at the outset of the experiment, participants will perform a task. Following the task, participants will be asked to report their prior belief about their relative performance. After that, they will be randomly matched in groups of two and be asked to choose between more informative and less informative feedback while varying the presence of strategic incentives, subjective judgement by others and revelation of one's feedback to others.

In summary, according to their experimental group, participants are asked to choose between either more informative or less informative feedback. We vary the costs and benefits for the more informative feedback to understand whether apart from preferences for more information, choice of feedback is affected by our proposed treatments. These costs and benefits are explained in the intervention section.
