Difficulties in reading others' minds make it difficult to anticipate their future behaviour. It has often been argued that such difficulties contribute to autistic individuals becoming enmeshed in criminal activity. However, supportive scientific evidence is virtually non-existent. We compared the ability of groups of autistic and non-autistic adults of similar intellectual ability to detect dodgy or suspicious behaviour across a wide range of scenarios. Although the autistic group performed more poorly than the non-autistic group on an established measure of mindreading, there were no group differences in the ability to detect dodginess. Nor did we find any evidence that detecting dodgy behaviour was associated with the degree of autistic traits reported by individual participants. However, when we combined the two groups, difficulty reading the minds of others was indeed associated with poorer detection of dodginess, thus highlighting a characteristic of individuals that may well increase the likelihood of becoming involved in crime or exploited for autistic and non-autistic individuals alike.
