Neurons, synapses, electrochemical receptors, and a compromised immune system.
I use the metaphor of a compromised immune system to describe the effects of propaganda, the polluted information ecology in which we are swimming.
Ultimately, the cognitive distortions are the disease of modern life, where we can no longer understand ourselves or our world, because the disinformation campaigns have impaired our ability to think rationally when we are in a constant state of stress, anxiety, and fear. We become stuck in the lizard brain, the limbic system, where we make emotional decisions and subsequently justify our actions with rationalizations.
