I find it hard to believe you have never seen social signaling 'in the wild'.

A lot of behaviour that otherwise seems nonsensical can be explained by social signaling.

Why do rich people often spend tons of money on things they don't need or use? To impress other rich people.

You are describing a theory of "some things are signalling", which is pretty different from "everything is signalling"

Yes I know. The person I was replying to seemed to not believe in signaling in general though.

I find it hard to believe you have never seen the flying spaghetti monster 'in the wild'.

This is not equivalent since it is reliant on the existence of the FSM, which is not usually taken to be proven, unlike (hopefully) the existence of other people.

How is the existence of other people proof of signalling theory? I believe you exist. Signalling theory could, for example, say I am holding up this argument on the internet because I want to show others how persistent I am. How does your existence prove or disprove why I am saying what I am saying?
