Science Disconfirms; Pseudoscience Confirms

Defining Features of Science vs. Pseudoscience

• Science disconfirms

  • Central attitude: actively look for evidence that could potentially falsify or challenge a hypothesis.
  • Embodies Karl Popper’s principle of falsifiability: a claim is scientific only if it can, in principle, be proven false.
  • Example scenario: A biologist proposes a new drug lowers blood pressure. She designs experiments seeking data that might not show an effect, such as placebo-controlled trials across diverse populations.

• Pseudoscience confirms

  • Core tactic: interpret any new data as supporting the already-held belief.
  • Employs confirmation bias—selects, remembers, or re-interprets evidence so it always appears favorable.
  • Example scenario: An astrologer explains a failed prediction by adding a new planetary “retrograde” clause, re-aligning the outcome with the horoscope.

Methodological Contrast

• Evidence Handling
  • Science: “What would disprove my claim?”
  • Pseudoscience: “How can I fit this new fact into my claim?”
• Iterative Revision
  • Scientific theories evolve or are discarded when conflicting data accumulate.
  • Pseudoscientific claims accumulate ad-hoc exceptions to avoid rejection.
• Epistemic Goal
  • Science seeks truth-tracking; welcomes being wrong as a path to refinement.
  • Pseudoscience seeks belief preservation; being wrong threatens the ideology.

Practical & Ethical Implications

• Misplaced trust in pseudoscientific practices can yield harmful real-world outcomes (e.g., medical quackery).
• Scientific willingness to be proven wrong underpins technological and medical progress.

Connections to Prior Knowledge

• Builds on earlier discussions of critical thinking and logical fallacies—especially confirmation bias.
• Reinforces the foundational scientific norm: hypotheses must be testable and falsifiable.
