Memes Model Proposal

From MemesAreDigital:

I recently considered simulating meme propagation. I wondered what constitues a meme and how to encode it (to simulate it). I considered the following parts:

These parts can be related in the usual higher order logic ways (existential/all quantification, conjunction). As well as associated with a trust indication (individuals can pass on that some actor trusts some meme).

I suggest you start with a simpler set of primitives. BreitenburgVehicles? are quite instructive here - they can express a meme through a simple matter of sensor placement and latching. The primitives above are way too high level to be ontologically null.

I postulate a length/complexity limit for a meme as well as a maximum number of memes held simulatneously (this could be set quite low for a simuation).

What memes can we build from such parts?

We see, that there is no need to explicitly introduce the concept time, because it is possible to refer to processes (someone or something reliably moves objects someplace). I assume, that a sufficiently complex simulation would quickly evolve time memes (as our ancestors did).

Why do you assume that? See http://ucsdnews.ucsd.edu/newsrel/soc/backsfuture06.asp for an obvious counterexample.

Now what are examples of these kind of memes?

If your memes began at a much lower level - down in distinctions (WhatsaDistinction) - then you might have something here. But as it is you just have some high level definitions defined in terms of some other high level definitions imho.

These memes can be correct (the statement made is correct) independent of there usefulness (a meme may say, that an indivudual trusts X which it doesn't, but if many individuals trust this mem it may be useful as a group effect).

How would you design experiments to test these hypotheses?

I would program a simulation environment, that has a limited set of locations (organized in some graph or fully interconnected). A very limited set of objects (say one type of 'food', one type of 'weapon', possibly also a predator or prey (to test coordination of individuals). The individuals have some hardwired set of behaviours which should include a desire to eat and maybe reproduce (we don't want to simulate coevolution of memes and genes yet). The individuals may hold a very limited set of memes or rather there should be a limit of the total meme size. Individuals keep only those memes, that they trust most. To track the trust we also have to associate each known individual with a trust value. This value is updated if memes got from that individual turn out to be useful or not. Also the trust in a meme is composed of the passed on trust assignments and the relative trust of the mentioned individuals. Trust is initialized on start or by reproduction (say). Individuals have an inference engine to derive actions from desires, memes and current environment (location, held objects, other individuals at this place). Obviously there should be some energy source (providing new food) and some way for mutation (otherwise the simulation may converge too fast).

Given a sufficient simulation of this kind I guess that
