If I understand it correctly, the claim is not that personal experience narration is a superior form of objective information to facts, it's that sharing personal experience is more likely to create a feeling of relational connection, which in turn is more likely to lead to a shift in position.
Tossing facts in an argument where people don't feel any personal connection is a bit like throwing stones at each other. Maybe the one with more and bigger stones gains a temporary advantage, but it leads to a retrenchment of positions, which doesn't help in the long run.
