Amélie Mummendey and colleagues empirical findings as well as a number of new theoretical models developed by them have been published in numerous books and prestigious journals.

[4] Together with Michael Wenzel, Amélie Mummendey developed the ingroup projection model (IPM).

Consequently, outgroup members are derogated and discriminated because they appear to deviate from the desired characteristics of the superordinate category.

A number of empirical studies support the main claims of the model and recent developments of underlying motivational and cognitive processes contribute to a deeper understanding of ingroup projection.

[6] Current research investigates, among other things, new pathways for the reduction or avoidance of ingroup projection and therefore possibilities to foster intergroup tolerance.
