Could you elaborate on that?

Consider the question: "Where did that viral video come from - why that video and not another video?" - That's the colloquial use of meme, but it's not a very useful question because the answer often "Random chance at the intersection of timing and relevance."

Consider the different question "When did it become unacceptable for males to have intimate friendships with other men?" Looking at the source of that, including with other ideas supported its creation and continuance - is essentially the only useful aspect of analysis of memes.

2timtyler8yMemetics consists of terminology and framework for cultural evolution. Cultural evolution covers a lot of hypotheses. For instance there's the hypothesis that the human brain swelled up to accommodate memes [http://on-memetics.blogspot.com/2011/09/tim-tyler-big-brain-as-meme-nest.html] or the hypothesis that memes made humans sociable [http://on-memetics.blogspot.com/2011/06/memes-and-human-ultrasociality.html] - since they need social contact between their hosts in order for them to reproduce - or they hypothesis that memes were implicated in the high frequency of speciation among our ancestors - just as songbirds speciate frequently [http://cfpm.org/jom-emit/1997/vol1/vaneechoutte_m.html]. There's quite a lot of associated hypotheses - no doubt some are correct and some are not.

Memes?

"All models are wrong, but some are useful" — George E. P. Box

As a student of linguistics, I’ve run into the idea of a meme quite a lot. I’ve even looked into some of the proposed mathematical models for how they transmit across generations.

And it certainly is a compelling idea, not least because the potential for modeling cultural evolution alone is incredible. But while I was researching the idea (and admittedly, this was some time ago; I could well be out of date) I never once saw a test of the model. Oh, there were several proposed applications, and a few people were playing around with models borrowed from population genetics, but I saw no proof of concept.

This became more of a problem when I tried to make the idea pay rent. I don’t think anyone disputes that ideas, behaviors, etc. are transmitted across and within generations, or that these ideas, behaviors, etc. change over time. As I understand it, though, memetics argues that these ideas and behaviors change over time in a pattern analogous to the way that genes change.

The most obvious problem with this is that genes can be broken down into discrete units. What’s the fundamental unit of an idea? Of course, in a sense, we could think of the idea as discrete, if we look at the neural pattern it’s being stored as. This exact pattern is not necessarily transmitted through whatever channel(s) you’re using to communicate it — the pattern that forms in someone else’s brain could be different. But having a mechanism of reproduction isn’t so important as showing a pattern to the results of that reproduction: after all, Darwin had no mechanism, and yet we think of him as one of the key figures in discovering evolution.

But I haven’t seen evidence for the assertion that memes change through time like genes. I have seen anecdotes and examples of ideas and behaviors that have spread through a culture, but no evidence that the pattern is the same. I haven’t even seen a clear way of identifying a meme, observing it’s reproduction, or tracking its offspring. Not so much as a study on the change of frequency of memes in an isolated population. Memetics today has less evidence than Darwin did when he started out; at least Darwin could point to discrete entities that were changing.

Without this sort of evidence, all the concept of a meme gives me is that ideas and behaviors can get transmitted, and that they can change. And I don’t need a new concept for that. Every now and then I’ll run a search on memetics just to see if anyone’s tried to address these problems — after all, a model describing how the frequency of ideas change in a population could be extremely useful to me — but so far I’ve seen nothing, and I don’t usually have the time to run a truly thorough search.

If any of you have, and if you know of evidence for the concept, please send me a link.
