“The dominant ideologies are not necessarily those with the best ideas—they are those with the best survival strategies.”
I’d add that it’s: idologies that survive and reproduce.
In your framework, spreading=reproducing.
Self-sealing and retention=surviving.
If an idea is open to revision or people changing their minds, it will likely “die” quickly. It needs to spread and then have self-protection mechanisms so the ideology doesn’t die when exposed to contradictory ideas.
Agreed about populism. Populism is “us the pure majority against the corrupt elites”, which can apply to all sorts of ideologies.
There’s right wing populism (e.g. “us the poor working class against the corrupt East coast elites”) and left wing populism (e.g. “us the poor majority against the corrupt corporate giants”, think the Occupy movement). There’s also populism in Latin America that’s more focused on fighting political clientelism, etc.
I think you could easily change the article to say “MAGA” instead of “populism” and get the same point across, though it’s not that big of a deal.
