The experiment poses the question: Are people willing to provide additional information in
situations where some will make better and some will make worse decisions based on the
information? It adds to our understanding of inequality acceptance.

Experimental Design
The experiment is a online-survey where participants make decisions over outcomes that matter for others. For that purpose, a representative sample of the US adult population was recruited. They answered basic demographic questions and then made a decision with real-outcomes for mTurk-workers.
