Your username suggests computer science ? <| sep |> I do this all the time . My teenage son hates when I crack myself up in public . I laugh so hard I have to stop in my tracks and cross my legs until I can collect myself after having multiple kids it ' s easy to pee a little . He gets a red faced and shifty and tells me I look crazy . My husband is just amused by me . I do this often , whether in public or not . I ' m the funniest person I know <| sep |> I ' m a simple man . I see '' I see shing , I upvote '', I downvote . <| sep |> That ' s actually simply not true . If you actually did research into the human brain ' s capabilities , you would learn that iconic songs and movie lines are exactly where the brain is NOT pretty solid . Because those aren ' t , to a brain that is trying to constantly search for and alert you to things that might get you killed , ALL THAT IMPORTANT . So perhaps you might , in turn , wish to consider that SOME OF US actually do study these things for a living and in order to teach them . Some of us actually know exactly what we ' re talking about . Second , and equally important , society DOES share quotes and stories and pieces in ways that are EXACTLY equal to the kids ' game telephone . If you ' ve never played it , go look it upand try it . Just once . Go ahead , we can wait . Then see how quickly information shifts even within a group sitting IN ONE LOCATION , AT ONE TIME . The same exact thing happens to large groups over time . It ' s NOT that special . It ' s NOT that unique . And it ' s NOT that incredible . It ' s actually very , very , VERY common . Third , even if your brain is recalling things perfectlyif you hear an incorrect quote MORE times than you hear the correct one , your brain WILL BEGIN TO BELIEVE that the incorrect one is the accurate one . This is how brainwashing works , actually . It ' s also how wrong movie quotes become ingrained in the societal consciousness . Again , REALLY common and not unique . Or unusual . At all . It is responses like yours that are so incredibly frustrating , because while you believe in your certainty so strongly , you ' re actually denying SOLID research , KNOWN effects and a very large body of knowledge on how stories and information spread . Which you are perfectly welcome to dobut please don ' t expect people like me to simply allow that to happen without at least TRYING to point out that your dogged determination to believe in perfect human recall is , itself , based on no research but your own belief .
