I was intrigued when learning about the super-memories only a small fraction of the population is born with. Today, there are four known people with super-memories in America. The attached link is an interview with Bob Petrella. Petrella is one of the four Americans' who has a super-memory. He explains how the memory is truly a blessing and a curse.
Having an average memory capacity, I would love to vividly remember playing at the state tournament for basketball or playing with my cousins during Christmas gatherings. Being able to call upon these memories would truly be a blessing. In this sense, Petrella is lucky to have this gift. However, I am thankful that I can forget certain memories, such as embarrassing or sad events that took place in my past. Petrella is one of the few who cannot let go of these memories, even if he wanted to. Holding onto every life experience can be seen as the downside, or curse, of the gift.
Petrella explains how his memories actually are like videotapes, and can vividly report on every past occurrence; sports especially. It this sense, it would appear that every person who has a super-memory is more prone to recall a certain aspect of life. These four Americans do have a few things in common. For example, all three of the four expressed left-hand dominance, while the fourth has "...strong tendencies to be left-handed." However, we cannot say that this trait causes super-memories or visa-versa.
Reading this article, I was curious if people with super-memories would make better life choice or could more accurately guess future happenings. People can base decisions off of past experiences. Since there are people that can remember everything about their past, wouldn't they make the best choices? It would appear as this would be the case, but I could not find scientific research to back up this hypothesis. Hopefully someone else will have insight on this idea?
