Modes of visual framing in neuropsychological deception detection research

ABSTRACT In the German context, where legal skepticism toward polygraph-testing intersects with emerging concerns about AI-based deception detection, neuroscientists position their work through methodological restraint and epistemic distancing. Their critical stance toward both visual determinism and applied polygraph-tests serves not only to manage uncertainty, but to claim scientific authority in a contested field. By tracing how visual framing enables both conceptual clarity and epistemic credibility, the analysis contributes to STS debates on the role of visuality in scientific knowledge production. It calls for closer attention to how images, practices, and imaginaries mutually shape what counts as evidence and epistemic possibility in neuroscience.
