I think theres some tech sway here. Ex: I wonder how technology changes how we recall events and WHEN we recall them. The plane that flipped upside down being a great example. Likely less than 1% of people use a diary to recount insanely major events of their lives. In the 1980s, lets say 80% of people used diaries/journals to recount the events of their lives. That number today is probably less than 1%. But NOW 100% of people use their phones to recount events via video. They dont try to remember what happened, since its there captured at the time of the event. Diaries recount the event after the information has decayed and there’s a minds-eye element to it, so it has additional subjectivity because reading a diary you have to imagine what happened in the past instead of a visual aid.
