Memory is a fickle thing to begin with, and to add another manipulative factor can cause us to believe things that may not be true. Loftus talks about how manipulative an active imagination can be in deciding whether we believe a certain event occurred. In experiments they conducted, they noticed that people who had an active imagination may remember events that didn't occur. They also were more inclined to believe things incorrectly. She ends with the conclusion that one can avoid making these mistakes by educating themselves.
However, while this may be true, i think that just plain education will not remedy this error. People will always remember things that they didn't actually witness. Different individuals place different importance on certain things. Whatever we consider important, its amplified, while other details fade.
