Takeaways

Memory is not reliable, and false memories can have serious consequences. Eyewitness testimony, although persuasive, can be misleading and faulty. Memories are not like recordings; they are reconstructive and can be influenced by external factors. Independent corroboration is crucial to verify the accuracy of someone's memory. Understanding the fragility of memory can help us be more tolerant of memory mistakes and prevent unjust outcomes like Steve Titus' case.
