Memetic driving works like this. Once imitation arose three new processes could begin. First, memetic selection (that is the survival of some memes at the expense of others). Second, genetic selection for the ability to imitate the new memes (the best imitators of the best imitators have higher reproductive success). Third, genetic selection for mating with the best imitators.

The first step means that new ideas and behaviour begin to spread memetically, from making tools and pots, to dancing, singing and speech. The second step means that the people who are best able to pick up the new memes have more offspring who are also able to pick up the new memes. So everyone tends more and more to imitate the successful memes. The third step means that mate choice is also driven by the memes that are prevalent at the time. The consequence of these processes operating together is that the direction taken by memetic evolution affects the direction taken by the genes. This is memetic driving.

Refraining from thinking is precisely the skill that is taught in meditation. In many traditions too much thinking is discouraged, and with good reason, because people frequently grasp ideas intellectually but fail to put them into practice. They may understand a difficult concept, but not shift their way of seeing the world.
