Scott Fraser studies how humans remember crimes -- and bear witness to them. In this powerful talk, which focuses on a deadly shooting at sunset, he suggests that even close-up eyewitnesses to a crime can create "memories" they could not have seen. Why? Because the brain abhors a vacuum. Editor's note: In the original version of this talk, Scott Fraser misspoke about available footage of Two World Trade Center (Tower 2). The misstatement has been edited out for clarity. Talk by Scott Fraser Learn more about your ad choices. Visit megaphone.fm/adchoices
