Overview
Background
Supported by over 20 external grants - including an ARC Laureate - 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. My most recent work focuses on understanding (and reducing) people’s motivations to reject scientific consensus, including the psychology of climate inaction. Matthew is currently leading the Net Zero Observatory at the University of Queensland, a multi-disciplinary group of academics and practitioners who design strategies to accelerate industry action and community support for rapid decarbonisation.

Research interests
-
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.
-
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
