The Brunswik Lens Model: a theoretical framework for advancing understanding of deceptive communication in autism.
Map every deception task onto four stages to see exactly where your autistic adult client needs help—creating, reading, weighing, or trusting cues.
01Research in Context
What this study did
Blackhurst et al. (2024) built a map, not a lab test. They took the old Brunswik Lens Model and gave it a new job: explain how autistic adults both tell and spot lies. The map has four stops—cue generation, cue recognition, cue utilization, and final judgment. The authors show where social-cognitive research already sits on the map and where future work should look next.
What they found
The paper itself reports no new numbers. Instead it sorts past findings into four clear boxes. The sorting shows that most autism work has focused on cue recognition—spotting shifty eyes or voice cracks—while almost no work tests how autistic adults decide to trust or doubt a speaker after they see those cues.
How this fits with other research
McGarty et al. (2018) ran a lie-detection game and found autistic adults were fooled far more often than neurotypical peers. Blackhurst’s lens model puts that result in the ‘cue utilization’ box, telling us the gap is not in seeing cues but in weighing them.
Keintz et al. (2011) showed autistic children can lie, yet their stories fall apart later. The model places this under ‘cue generation’—kids create weak cover stories that leak details. Together the child and adult studies trace a life-span path: production problems early, detection problems later.
Schuwerk et al. (2015) found a quick peek at the right answer improved autistic adults’ eye-tracking Theory-of-Mind scores. The lens model predicts the same brief exposure could boost ‘cue utilization’ during deception tasks, a testable idea the authors call for.
Why it matters
If you assess social skills in autistic adults, stop labeling the whole domain as broken. Use the four-stage lens to find the exact stage where each client stalls. Then write goals that build that stage—maybe cue weighing drills after you teach them what a shaky voice means. You turn a vague social deficit into a pinpointed skill plan.

03Original abstract
Due to differences in social communication and cognitive functioning, autistic adults may have greater difficulty engaging in and detecting deception compared to neurotypical adults. Consequently, autistic adults may experience strained social relationships or face increased risk of victimization. It is therefore crucial that research investigates the psychological mechanisms that are responsible for autistic adults’ difficulties in the deception process in order to inform interventions required to reduce risk. However, weaknesses of extant research exploring deception in autism include a heavy focus on children and limited theoretical exploration of underlying psychological mechanisms. To address these weaknesses, this review aims to introduce a system-level theoretical framework to the study of deception in autistic adulthood: The Brunswik Lens Model of Deception. Here, we provide a comprehensive account of how autism may influence all processes involved in deception, including: Choosing to Lie (1), Producing Deception Cues (2), Perceiving Deception Cues (3), and Making the Veracity Decision (4). This review also offers evidence-based, theoretical predictions and testable hypotheses concerning how autistic and neurotypical adults’ behavior may differ at each stage in the deception process. The call to organize future research in relation to a joint theoretical perspective will encourage the field to make substantive, theoretically motivated progress toward the development of a comprehensive model of deception in autistic adulthood. Moreover, the utilization of the Brunswik Lens Model of Deception in future autism research may assist in the development of interventions to help protect autistic adults against manipulation and victimization.
