The link to Assistant Village Idiot's piece on signaling and politics, in which he proposes, just for the sake of discussion:

Let’s pretend for purpose of discussion that all our religious, political, and social beliefs are entirely hollow. They have no intellectual content to speak of, and are mere social signals. We use them as birds use song, marking territory, calling attention to ourselves, attracting mates. We use a particular vocabulary of values to keep some people away and draw others in, to attempt to assign ourselves a certain status in the world.

Bumper stickers, what is displayed in your office, and choice of avatars are essentially just social signaling.

I decided to try to learn just a little about Signaling Theory, but first I had to make sure the word didn't have two "l"s, so as to avoid signaling that I am a dunce. (It's one of those many words that the Brits spell wrong.)

Moving ahead, I learned that the sociological/economic/game theory notion of signaling comes out of biology and animal behavior. I found a good introductory piece on the subject, Honest Signalling Theory (I noted that this American Bio prof likes to use two "l"s.)

It's an interesting multi-page piece which begins:

The gazelle's leaping behavior, the nestlings' begging, the expensive suit - all of these things are signals. All are intended to convey information about a signaller, to a signal receiver. For humans, the fancy suit - like a fast car, an expensive bottle of wine, or a precious gemstone - indicates some property or quality of the signaller. In this case, that property might be the relative wealth of an individual.

I realized that maybe I do more signalling than I would like to think. Then I stumbled into a piece by Econlog's Caplan after reading some brief essays about education and signaling (Would you rather have a Berkley Diploma and No Education, or Education and No Diploma? and Jane Galt's Who are we signalling? and Tyler Cowen's Why Education is Productive - a parable of men and beasts) about the signaling value of education. Is education purely about social signalling? Of course not, but partially, yes.

Caplan, in Mixed Signals asks:

Which would do more for your career: A Princeton education, but no diploma, or a Princeton diploma, but no education?

All my personal experience (30 years in school!) tells me that there is a lot of truth in the signaling model. I don't use most of my schooling in my job, and I'm a professor, for God's sake! But would I have my current position if I had failed high school Spanish? No way.

Well, this was all fun, but one is quickly reminded of how often people who have cool ideas tend to get reductionistic about them: Man is all about economics, man is all about gender, man is all about libido, man is all about adapting to his environment, man is all about signaling, etc, etc. So if you look at the world through a "signaling" lens, all you will see is signaling. And now I am out of time and getting too long anyway.
