Baking Soda Volcano Bias

The fundamental and arrogant misconception that all fields of science, and indeed the entire pursuit of knowledge, are as simple and easily reproducible as a grade-school baking soda volcano experiment. It’s the bias that leads people to think they can dismiss climate science, epidemiology, or evolutionary biology with the same casual confidence they'd have criticizing a failed baking project. It’s a metabias because it colors how you view the entire process of science itself—as a trivial, one-off trick anyone can do.

Example: "He watched one YouTube video and now thinks he knows more about vaccine development than the entire CDC. Textbook Baking Soda Volcano Bias."
