Caught on camera. How visual evidence shapes human decision-making, and how this might be regulated.

Footage from cameras that have recorded an arrest, chase, confession or crime scene in real time is also called 'evidence verité'. Many people think that these kinds of images show what really happened; "camera images do not lie". This ties in with naïve realism: the human tendency to believe that images show reality. Thanks to this naïve realism, we often find it unnecessary to discuss the meanings of camera images or a photo: the images speak for themselves. But images don't speak for themselves. The viewers do this, they interpret the image. What an image shows (and what not), how it is presented, and in which context, all affect the viewer's interpretation. The question that arises is when this interpretation is useful, and when it is harmful for the process of fact finding. In this presentation I will discuss insights from two (ongoing) collaborative, mixed-methods research projects for Police and Science, in which we examine this question and explore how the use of camera evidence in investigative policing can be more effective and less biased. Questions that I hope to discuss with the audience are whether, and when AI can be a helpful means to reduce unwanted bias
