Memes and Transmission Pathways

From, Why Cultural Evolution Is Real (And What It Is)

(Because watching other people say that thing you were saying and be like ‘omg I was saying that’ and then they give it their own twist and you are like ‘oh yes I see where this is going and it gets back to the morality model’ and then the joy at how much fun it is.)

(Guys guys we are talking about memes, okay. And the big question brought up by the part I quoted is, of course, What are the long-term effects of changing transmission pathways?)

Quote:

“How Transmission Pathways Matter

In my outline, I mentioned that the transmission pathway – vertical or horizontal – matters a great deal for the content and friendliness of transmitted cultural items.

In biology, there is already support for this model. Parasitic entities like bacteria that are limited to vertical transmission – transmission from parent to child only – quickly evolve into benign symbiosis with the host, because their own fitness is dependent on the fitness of the host entity. But parasitic entities that may accomplish horizontal transmission are not so constrained, and may be much more virulent, extracting high fitness costs from the host. (See, e.g., An empirical study of the evolution of virulence under both horizontal and vertical transmission, by Stewart, Logsdon, and Kelley, 2005, for experimental evidence involving corn and a corn pathogen.)

As indicated in an earlier section, ancient cultural data is very tree-like, indicating that the role of horizontal transmission has been minimal. However, the memetic technologies of modernity – from book printing to the internet – increased the role of horizontal transmission. I have previously written that the modern limited fertility pattern was likely transmitted horizontally, through Western-style education and status competition by limiting fertility (in The history of fertility transitions and the new memeplex, Sarah Perry, 2014). The transmission of this new “memeplex” was only sustainable by horizontal transmission; while it increases the individual well-being of “infected carriers,” it certainly decreases their evolutionary fitness. …”

Okay, right. So your meme-mitochondria will most likely protect you from dying, but don’t much give a shit if you end up killing people who are not-you or at least don’t share your genes. And meme-viruses will try to get you to not kill society at large (which is busy propagating them,) but don’t particularly care if they kill you.

Reflections:

1. Will modern mass-media destroy itself by accidentally destroying the people that use it? Can mass-media be a stable, long-term part of the human cultural/technological toolkit?

2. Does modern mass-media create an actually different moral meme-environment from the vast majority of the human past? Is this good/bad/neutral?

3. Will we evolve to be adapted to this meme-environment, say, by people who believe that Western Education is Sin kidnapping girls, selling them as brides, and then massively out-breeding people who “Lean In”?
