IDeA Lab · Identity, Decisions & AI

How do people decide who someone is?

The IDeA Lab at UNSW Sydney's School of Psychology studies face recognition, memory, and identity decisions in the places where they matter most: policing, digital identity, evidence, and human–AI interaction.

Featured insight

“People are often confident in what they see and remember — but it is only when their ability is tested, that the gaps become clear.”

— Dr James Dunn

What we do

Research for decisions that cannot rely on guesswork.

We study how people perceive, recognise, and remember identity information. Our work connects cognitive science with practical problems in policing, security, legal evidence, and digital systems.

The lab uses behavioural experiments, eye-tracking, computational approaches, and real-world tasks to understand when people are accurate, when they are overconfident, and how human decision-making changes when AI enters the process.

For example, we study how passport officers compare faces, how police remember critical incidents and how people identify AI-generated faces online.

Research themes

How important decisions are made, tested, and improved.

01

Face recognition in the real world

Understanding why some people are unusually good with faces, and how recognition ability can be measured fairly — so the right people can be identified and deployed in high-stakes roles.

02

Memory under pressure

Studying how stress, uncertainty, and context shape what people remember and how confidently they report it — so evidence can be interpreted more accurately and errors reduced.

03

AI-generated faces

Testing whether people can detect synthetic identities, what cues they use, and how AI changes trust online — so we can understand and mitigate risks from increasingly realistic fake identities.

04

Evidence and expertise

Evaluating how expert and non-expert decision-makers compare forensic evidence, interpret information, and avoid error — so identity decisions are more reliable in legal and investigative settings.
