herefore, I think memetics is a useful intellectual tool for thinking about cultural transmission of ideas, but a science it is not.
Never said it was a science.
but that is pure nonsense that implies some sort of teleology to human society. I don't think it's true that correct ideas will win out, afterall some god awful ideas have managed to exist for a generations despite the wreck and ruin they have brought eg nationalism, racism, homophobia and sexism.
'Good' and 'bad' don't come into it since they're value judgements on morality, not on the ability of an idea to continue to survive. While I don't want to plug the meme thing too closely to genes, what about parasites and disease carrying organisms which are wholly destructive (e.g. ring worms) to their hosts and environments - they are effective survivors but can be called 'bad' from the perspective of higher order animals.
The application of meme theory ideas of propogation, infection and transmission (I'll get on to epidemiology in a minute) are useful tools to find out HOW and WHY ideas move around society, how they change/can be changed and how to make the best use of 'positive' memes - such as tolerance, egalitarianism, more effective at settling in the mas psyche.
The bit on epidemiology is that in word of mouth 'phenomena' the patterns of knowledge distribution often mirror the patterns seen in viral outbreaks - again, these are
models that can be used for specific purposes.
It's not like I, or anyone else, I making some kind of ultimate claim that meme theories are the be-all and end-all of HOW idea come to be, but they're a useful tool for showing how they spread and so on.
And a I've said, it works in this thing called 'the real world'. I've planned and used marketing strategies that are based on computer models of meme distribution and they've been successful at conveying complex messages to communities that are often ad-resistant (A group conservatives) that have reached the planned coverage numbers 2-3 weeks earlier than planned.
Phil, you might like to say that it's all a load of cock, but I've got real world experience of using the models and seeing them work. AFAIC that's something I'd call 'proof'.
