Dark patterns
Dark patterns are defined as being “a user interface that has been carefully crafted to trick users into doing things,” but I think the idea can and should be expanded to include any pattern of behavior or design intended to take advantage of people’s cognitive biases.
There’s a Netflix documentary series called “How to Become a Tyrant” that is a good example of patterns that make the world worse as a rule.
I also think that Donald Trump used patterns of behavior intended to trick people into believing his lies.
