My research

aims at analyzing the impact of messages of science denialism on individual’s health decision-making as well as designing interventions to reduce its influence.

Science denialism is an approach that has the ultimate goal of rejecting a proposition on which a scientific consensus exists. In the age of mass media science denialism has multiplied its reach and availability, which threatens the acceptance and lifesaving use of health-treatments and prevention behavior – e.g. HIV-treatments or vaccines. Deniers use different techniques, such as conspiracy theories or false logic, to promote their messages of science denial.

In order to understand the influence of these messages on individuals’ health decision-making I apply an empirical judgment and decision-making perspective. Furthermore, I use literature from the areas of debunking, inoculation and rebuttal to design and test promising interventions. I aim at generating basic research results, which are applicable for recommendations and guidelines for health authorities.
