Interesting! Without going into personal details, can you explain what sort of incongruence he found between his diary and his memory?
I sometimes keep a diary, for example when I go on long trips that are different from my day-to-day life. I try to be as accurate as possible, but sometimes i notice what i write isn't fully representative of my state of mind at the time, simply because when you're writing stuff down (especially when you're writing with a pen and paper (slow!)), you can never fully capture all the concurrent thoughts and emotions you're experiencing, so its impossible for a diary to be fully accurate. Undoubtedly, e.g. Elizabeth Loftus has done a lot of prominent research in that field, our memories tend to be fallible, but maybe that's part of the reason?
When I was writing a paper on the history of D, I had kept a lot of records, such as emails. I was often surprised when the details didn't quite line up with my memories.
This is one reason why one cannot get a fair trial 40 years after the fact, if any of it relies on eyewitness testimony.
