Idle speculation on a source of new memes.

I was just idly peeling an egg this morning, and breaking up the shells to throw into the compost for recycling, when I remembered an old childhood tale about eating hard-boiled eggs. It says that witches can only cross water riding in eggshell halves, so if you want to prevent a shipwreck caused by a witch, you should always crush your eggshells when done with them.

Now, the interesting thing is that these two memes:

1) Whole eggshells don't compost well -- fragments do; and
2) witches need whole eggshells

compete to cause the same behavior. I can even see how, a few hundred years ago when family farms were the norm and composting was common, they may have had a sort of symbiotic relationship.  You see, if a parent was infected with #1, he may well wish his huge brood of kids to share his behavior. The trouble is, telling them that it helps the compost is not going to have a lot of sway on kids. Kids are fairly immune to meme #1. On the other hand, meme #2 causes the desired behavior with far more reliability.  As the kids age, a signifigant portion (although probably far less than 100%) will slowly become immune to meme #2. Now, they may then ask their parents why they were told such an outlandish thing, and thereby get infect by #1, or they could simply pick up meme #1 from the local farming community, once they are old enough to care about the quality of their compost. What is likely though, is that once infected with meme #1 and having kids of their own, they may well deliberately infect their kids with meme #2 to get the desired effect.

So, now we have a mechanism whereby one can start with a population of rational and sensible adults and end up with the propagation of a nonsensible and irrational meme.  Now, there is no way of knowing if the above scenario ever actually happened, but its plausible enough that I'm sure similar things have happened.
