Understanding Uncertainty in Forensic Science and the Law - Dr Kristy Martire

What is this research about?

Uncertainty is an unavoidable part of science and science communication. It is also a central element of decision making in the law. However, the expression and interpretation of uncertainty can be challenging.

What does it mean to believe someone is ‘guilty beyond a reasonable doubt’? How much weight should be given to evidence that is described as providing ‘strong support’?

In this project lay, legal and scientific perspectives on the formulation and comprehension of uncertainty are explored in order to improve science communication and criminal justice outcomes.
