Mock juror perceptions of credibility and culpability in an autistic defendant 2018

One-hundred-and-sixty-one jury-eligible participants read a vignette describing a male who was brought to the attention of police for suspicious and aggressive behaviours and displayed atypical behaviours in court. Half of participants were informed that the defendant had ASD and were given background information about ASD; the other half received no diagnostic label or information. The provision of a label and information led to higher ratings of the defendant’s honesty and likeability, reduced blameworthiness, fewer guilty verdicts, and more lenient sentencing. Thematic analysis revealed that participants in the label condition were more empathetic and attributed his behaviours to his ASD and external factors, while participants in the No label condition perceived the defendant as deceitful, unremorseful, inappropriate and aggressive.

The study employed a between-participants survey design whereby mock jurors were randomly assigned to one of two label conditions: ‘Label+info’, in which mock jurors were informed that the defendant was autistic and were given further information about the condition and how the individual was affected by it; or ‘No label’ in which no diagnosis or information about ASD was provided. All participants completed the study on the online Qualtrics data system. More information is given in the 'Methods' file.
