my idea of "false memories" is a movie called The Way We Were.
I see "false memories" in my daily life, and when I hear about what my ex-wife said to my sister five years ago. . . .
I might even try to argue that the term is an oxymoron, especially when it involves money, or lawyers.
but as for your obvious real topic, let's just say people are fragile, though not as fragile as our grasp of reality. . . . . if people can't stretch things, they break them.
People sometimes find unbelievable ways to cope with huge inconsistencies between their "real" vs. "ideal" takes on things. One way to maintain a healthy mind is talking, or writing. It's a good life skill, with rewards in unexpected areas. . . . like dealing with trauma, major accidents, or other horrific crises in life. . . . .
belief in "authority" is imo a major source of "false memory" phenomena. People who are focused on authority issues sometimes really can't connect reality.
