If truth is about repeated experimentation or journalistic records (a very new concept in history of writing - less than 500 years), then perhaps this is of concern.
I accept both definitions, but when they’re in conflict, the former tends to be more end-to-end, while the latter tends to overfit to the moment. Mostly because data is scarce and life is a very complex distributed system. On the other hand, the former changes slowly while the latter perhaps keeps up with the pace of change.
Except the point of life is probably to thrive more than to collect a list of facts. So when in conflict, I lean towards the former. Personal choice tho. I expect most of HN leans the other way.
