Overview

Since graduating in 1999 I have published over 200 papers, and in 2018 I was elected a Fellow of the Academy of Social Scientists in Australia. Supported by over 20 external grants, I am known for developing insights around three themes: (1) rejection of science and technology, (2) pro-environmental behaviour, and (3) intergroup relations. In each domain I have developed unique models designed to understand the logic behind supposedly “irrational” behaviour, and used them to facilitate attitude and behaviour change.

Research Interests

  • Prejudice and intergroup relations
    I examine the psychology of why hostility emerges between nations, religions, ideologies etc. I then use these insights to examine what can be done to ease intergroup tensions.
  • Conspiracy theories
    I examine why people believe in conspiracy theories, the consequences of conspiracy theories, and strategies for reducing their negative impacts
  • Rejection of science
    I examine the psychological motivations for people to reject scientific consensus, with a particular emphasis on the psychology of climate change skepticism and vaccine hesitancy.
