Mariela Jaffé is a PostDoc at the University of Basel in Switzerland. Her main research interests are decision making aids (e.g., using a coin flip to make a decision), diversity preferences (e.g., when do we prefer to work with different or similar others), judgments of truth (e.g., when are we more likely to judge an ambivalent statement as true), and dishonest behavior (e.g., when are we more likely to present ourselves as slightly better than we actually are).

I am currently very interested in studying the impact of random decision-making aids (such as a coin flip) in experimental settings. You can find an article on this topic here (English) and here (German).
Furthermore, I am also investigating the effects that decision procedures have on the diversity of groups and how diversity experiences may impact individuals' subsequent behaviour. You can find more information about one of my projects here (English) and here (German).
I also study judgments of truth and the interpersonal consequences of sharing secrets.
If you have any questions regarding my work, please don't hesitate to contact me.
