> I used to think I could recall conversations, but how do I know they actually happened? That seems trivial to verify; just record details about all conversations you have with everyone. I have been doing this since 2009. I have a 5 MB yaml file with details of every conversations (mostly tags), and I might have an above-average memory but yeah I definitely forget things .... (and sometimes I get some of the details wrong even if a conversation happened just minutes ago). Another way to verify (to yourself only) is to writeup your memory of a conversation, PGP sign it, hash it, give the hash to a friend who was originally in the conversation, then have them do a writeup, then reveal the commitment and compare the two accounts of a conversation. The writeup would be better if it was done immediately after the actual conversation, because otherwise social groups have time to mingle and confuse everyone about what actually happened. Another way is to do a public group writeup of a conversation after it happens (or an audio/video recording), then have everyone PGP sign the writeup (to confirm their agreement), then later pick a random conversation where this setup was performed, and write down your memory of the conversation. This doesn't work if the conversations where this setup is performed are all unique; probably has to be a few thousand different setups happen before this starts to test memory in any meaningful capacity.
