Autism is characterised by differences from non-autistic people in social communication and interaction, alongside repetitive, stereotyped and restricted behaviours, activities and interests (American Psychiatric Association, 2013). One specific area of social cognition in which autistic people1 differ from non-autistic people is their preference and performance in reasoning and decision-making (Morsanyi & Byrne, 2020; Rozenkrantz et al., 2021; van der Plas et al., 2023).
