The bad memes mental model originates from Richard Dawkins' concept of the "meme," which refers to a unit of cultural transmission. A bad meme (or viral meme) is a piece of information that harms its host (humans) by spreading through imitation and replication across minds, ultimately reducing the host's adaptability. The core idea of this model is to encourage people to critically examine the information and cultural ideas they absorb—identifying and avoiding "bad memes" that are misleading, factually incorrect, resistant to evaluation, or detrimental to personal development—so as to navigate a complex world more effectively while maintaining independent thinking and rational judgment.
