not vary.

But what are the messages? This took me quite a few months to figure out. I finally realized that the messages were conditional probabilities in one direction and likelihood ratios in the other.

we cannot assume that everything interesting is at the same scale as ourselves.

some form of complexity theory is required if we are to understand many of the intimate, and patently uncertain, interactions found in modern society.

instead of representing probability in huge tables, as was previously done, let’s represent it with a network of loosely coupled variables. If we only allow each variable to interact with a few neighboring variables, then we might overcome the computational hurdles that had caused other probabilists to stumble.
