Today we have Prof. Dr. Ilja van Beest, from Tilburg University, in our SWE colloquium talking on “Ostracism: Financial threats, survival threats, inclusion threats, and religious threats.” Here’s the abstract:

Recently we summarised 10 years of ball tossing in a meta-analysis of ostracism research (Hartgerink et al, PlosOne). We observed that the average effect size of ostracism approaches 1.5 standard deviations. This generalised across structural aspects (number of players, ostracism duration, number of tosses, type of needs scale), sampling aspects (gender, age, country). In the current talk I will provide an overview of the studies on ostracism that inspired us to conduct a meta-analyses. Specifically, I will present research on the relation between ostracism and (1) financial threats, (2) survival threats, (3) inclusion threats, (4) religious threats.
