Jury bias refers to the tendency of jurors to make decisions based on preconceived notions or personal beliefs rather than the evidence presented in a trial. This bias can stem from various factors, including media coverage, cultural background, or personal experiences. When jurors allow these influences to affect their judgment, it can lead to unfair trial outcomes. To mitigate jury bias, courts often implement measures such as jury selection processes and instructions to jurors. These steps aim to ensure that jurors remain impartial and focus solely on the facts of the case, promoting a fair legal process for all parties involved.
