Dr. Philipp Sprengholz

Philipp Sprengholz received his M.Sc. in Cognitive Neuroscience and Cognitive Psychology from Friedrich Schiller University Jena in 2018. In his dissertation project, he investigated the effects of coercive and rewarding measures for increasing vaccination uptake. He is interested in applying state of the art technology as well as implicit methods in his research. Before becoming a psychologist, Philipp Sprengholz graduated in engineering and gathered several years of professional experience in the IT industry.

Areas of expertise: societal polarization, psychological reactance, policy acceptance and resource allocation preferences in health contexts
