In her book "Brainwashing: The science of thought control", Kathleen Taylor describes 5 (FACET) factors that can help to prevent totalist and dogmatic thinking:
- Freedom (of speech etc.)
- Agency (freedom of action)
- Complexity (the varied mix of human opinion, values and decisions; avoiding cliched thinking)
- Ends-not-means (individuals, not cogs within a larger machine)
It seems to me that Interactive Democracy reinforces and encourages these factors. Maybe that's a small thing given that Parliamentary Democracy also requires these elements (to a lesser degree) but history shows us that dogmatic beliefs, whether religious or political, have a tendency to emerge and re-emerge, often with detrimental effect, so any extra antidote could be good.
