My research is focused on understanding the similarities and differences between human, animal and machine minds. At the heart of my research program is an experimental framework I term the signature testing approach. This uses the information processing errors, biases and other patterns agents exhibit to make inferences about the content of different minds. This approach generates powerful intelligence tests that strongly constrain the possible cognition an agent is using and allows for the comparison of both biological and artificial intelligences. I also have a keen interest in understanding the role information processing errors and biases play in human decision-making, and particularly whether it is possible to debias the judgements human make.
