Variety is good for evolution, so I guess having only ideas being fit when they are close to a majority cultural aspiration would actually limit the applicability of the gene-meme analogy in this context. I am actually afraid that the error correction mechanism is this oligoculture we witness which to me indicates that memevolution is short lived and will have to evolve itself. Wondering whether oligo culture and the move of Overton windows is for memeevolution to use physical survival in the context of conflicts as a means to error correct.
