We form binary models, because that way information storage in the brain and retrieval therefrom becomes efficient. "Screw him, he's a jerk.", so you say to yourself sometimes, because he didn't support you in a meeting, because he appeared callous and thankless once. Its kind of like the way engineering students model a system; there are those loops and connections and parameters and there are values. Similarly we form models in brain, to model our experiences, to model the people we deal with, run into. A bad dealing and you say to yourself, " The man is a sorry fuck".

The brain is pretty naive (well may be not really, it allows you to fathom how it functions, do you see what I mean), but who is to blame, it needs to store information efficiently!

But one can try to make a more elaborate model, a model that captures information from previous episodes and dealings, that which has tolerance to ambiguity, that which allows one to twist and tweak parameters, that which prevents one from thinking in white and black.

I couldn't complete the project, I am not smart. I couldn't make the submission, I suck hard. I think we are pretty hard on ourselves too. May be if we try to form non-binary models, some synaptic connections in the brain reconfigure and they do that for good.. they better, right :)
