An anecdote combined with anomalies and symbols grounds an inference. Personal experiences mean more than polls or numerical charts. Symbols portray subconscious projections. We project our own needs, experiences and feelings. Symbols have a way of predicting.
People often follow their own projections.

When a discovered trend has anomalies and symbols, it is twice as exciting because there is an added emotional commitment in the subconscious that is going in this direction. The demographic technique traditionally is a number game.
