So, "everything" is compression! What do you mean by "everything"?

From what I see here, every cognitive process generates complexity drop. I don’t see why.

So it seems that probability, aesthetics, creativity, relevance, responsibility, even humour, and many more, correspond to compression. Maybe it is just due to the way our brain functions.

Or maybe one could say that any computation leads to information compression. I disagree. For instance, your brain is processing the syntax of what I’m saying, and...

and you mean that there is no complexity drop when processing a sentence? Indeed! At least not at the syntactic level.

And yet, once you get the syntactic structure, words fall in place, and the sequence of words becomes less complex. OK. Now I see your point. But that form of complexity reduction is quite different.

You mean, it’s not a difference between expected complexity and observed complexity? That’s it.

Maybe we should say that we are more concerned about "explicit" complexity drop here? Yes. The kind of compression you can experience... and talk about!

This "explicit" form of compression is what determines surprise. To me, it’s the amazing side of complexity drop.

As in fortuitous encounters: you expect to meet someone complex and you see your neighbor. My favorite is the story about Larry Kagan’s structures: you expect a complex shadow and you see something familiar projected on the wall.

Did you see the next topic? It’s about emotion. Yes, I wonder what complexity drop has to do with emotion.
