A recent study has shown that jurors who are shown surveillance video, in slow motion, of criminal acts committed by defendants often suffer from ‘intentionality bias’. Even when reminded that the footage was artificially slowed down, unanimous juries were four times more likely to convict when they viewed slowed-down video than juries who did not. The study shows that jurors ascribed greater premeditation and intent to these defendants, despite the reminders, resulting in higher conviction rates as well as more severe sentences.
