Why are most eyewitness testimony are inaccurate?

Most eyewitness testimonies are inaccurate due to factors such as the malleability of memory, stress during the event, and the influence of leading questions or misinformation after the event. Stress and trauma can impair an individual's ability to accurately recall details, while the brain may fill in gaps with incorrect information. Additionally, biases and assumptions can distort what a witness believes they saw, leading to further inaccuracies. Overall, the reliability of human memory is often overstated in legal contexts.
