Behavioural Science

Our expertise


The Department of Psychological and Behavioural Science (PBS) brings together international experts at the forefront of behavioural science, to undertake research that seeks to understand, predict and change human behaviour.  

Our work informs policy in the UK and Europe, including ongoing research relating to COVID-19. LSE experts in the field of behavioural science continue to engage with policymakers and private companies to inform and drive measures of happiness, behaviour change, inclusion and sustainability. 

Experts in the department have paved the way for the use of behavioural science research techniques to test cognition and behaviour, including those found in the LSE Behavioural Lab for Teaching and Research.

Work in the department addresses the following broad themes and topics:

  • Climate change 

  • Ethical behaviours and decision making 

  • Happiness and wellbeing 

  • Mental health and economic outcomes 

  • Health and public policy 

  • Technology and data 

  • Workplace culture 

  • Risk-taking behaviours. 

Our research is anchored in a shared evidence-based approach that is theoretically informed and policy relevant.
