Falsifiability

Mental models

Popper's boundary between knowledge and story: a genuine thesis specifies the evidence that would prove it wrong. Write the kill criteria at purchase - the numbers or events that would mean you were wrong - and hunt for them harder than for confirmation. A thesis you cannot kill is not strong, it is untestable.
