Bravo !
Excellent concept. And I suggest it might be improved and put to practical use right here on the OCT forum.
Instead of looking at collective statistics, look at age (as a range) of each individual who posts here. We already are shown avatar (worthless), number of posts, number of stars, etc. But age range is certainly far more useful as a possible gauge of wisdom. Not guaranteed correlation, but more useful than avatar or stars from "likes". Make stating age optional. In 5 year ranges. (The highly paranoid could simply lie.)
There are already some indicators of age available here. If I see a post or private message that begins, "Hey, Bro. How's it goin'," I start moving my mouse to the "ignore user" feature. Likely little wisdom from that user.
Another indicator -- widespread, but far more subtle -- is thinking in terms of collectives. "What does everybody here think about ..." Thinking in terms of collectives started to come in vogue in the 1980s and has been trending upward ever since.
There are more clues along those lines. But what I'd like to see -- in line with
@wellington's idea -- is a positive clue here to the wisdom of age.
Alas, for me, the poll at the top of this thread does not go high enough. I'm older than the highest age range. It is difficult to find anyone senior to me, who is still functioning in life: not in a nursing home, not dementia, etc. Sad, eh?
No, not so sad, because having no one senior to ask for guidance and advice, I've learned to depend even more than before on my own judgement.
To finish this post, I will pass along one bit of such wisdom that I learned at a young age, from people of a much older age. It is a German Idiom (but I have no German, so I must use English): "We grow so quick old, but so slow smart."
