Compressed Representations Schemas

Say the word "restaurant" and a whole scene rises in your mind: tables, menus, a bill at the end. Nobody taught you the scene as a list. The mind compressed hundreds of visits into one compact pattern, and now the single word unpacks it.

This is how the mind stores almost everything — not as footage but as summaries. A schema, in the plain sense, is a pre-built answer: what a wedding is, what an argument is, what a stranger on a train is.

The gain is speed; the loss is freshness. Meet a new person and the mind does not meet them — it unpacks the nearest schema and meets that. The individual arrives; the template answers.

So check, now and then, whether you are seeing the person or the pattern. The compression is unavoidable — the mind cannot afford raw footage. But the wise hold their schemas loosely, ready to be corrected by the actual human standing there.
