Research interests


My ongoing thesis is about belief in conspiracy theories in the context of intergroup relations.

In the Identification with All Humanity Lab I have been testing equivalence of the IWAH scale in France, researching the universality of the associations between IWAH and a range of humanitarian measures as well as linking IWAH with conspiracy belief measures.
