I have a habit of using autobiographical stories to make points in discussions and arguments online. I do them because it is the only stories I believe I truly have a proper right to tell: they are me, from me and of me, and no one else can tell them properly from that perspective but me.
Traditionally, this is considered “anecdotal evidence” and for some reason anecdote is not as important as statistical or a logically consistent theoretical stance. Not only that, many say “it is invalid evidence” because it is anecdotal.
But I find that absurd. They each serve a purpose in the process of determining truths and a good true personal story will convince in a way that a bare set of numbers on a graph cannot.
In a sense, it serves the same purpose as a good headline, just a little longer.
