Trial by social media : how do you find the jury, guilty or not guilty?

Social media makes it easier than ever to access information and opinions associated with criminal proceedings, and viewing or discussing these pre-trial could reduce juror impartiality. This study explored whether viewing biased social media comments would influence mock juror verdicts. Seventy two participants formed twelve 6-person 'mock juries' and all participants received information regarding a murder trial. Nine groups were exposed to social media comments, manipulated to be negative, positive or neutral towards the defendant. Three groups only received trial information (control condition). The results showed that prior to group discussion, exposure to negatively-biased comments led to more guilty verdicts, however these effects disappeared after group discussion. Therefore, although jurors may be unable to remain impartial before a trial, jury discussion can remove these prejudices; supporting previous research. Further research is suggested where participants interact actively with social media, rather than passively viewing comments.
