The main aim of the research study: Conspiracy theories in Bosnia and Herzegovina: a psychological study of conspiracy theory beliefs in a post-conflict society is to identify what beliefs in conspiracy theories are held by citizens of Bosnia & Herzegovina, how prevalent these beliefs are, and what other determining factors are at work in the holding of such convictions. A conspiracy theory can be broadly defined as a set of oversimplified and in many cases false beliefs in omnipresent and nefarious groups, that are driven by harmful and evil aims, and that coordinate the activities that they organise.
