Distinguishing Science from Pseudoscience

Aug 31, 2024

Lecture Notes: Science vs. Pseudoscience

Introduction

  • Presenter: Dr. Johnson Hoss
  • Topic: Differentiating science from pseudoscience

Characteristics of Science

  • Willingness to Change:

    • Science adapts to new evidence, refines views to match reality.
    • Example: Adjustments in physics with Einsteinian relativity.
  • Peer Review:

    • Essential and ruthless; ensures accuracy and thoroughness.
    • Science builds reputation on evidence and results, not bluster.
  • Accountability to New Discoveries:

    • Open to all evidence, not just favorable results.
    • Adjusts previous models rather than dismissing them entirely.
  • Inviting Criticism:

    • Science thrives on open criticism and discussion.
    • Criticism is seen as an opportunity to refine and improve.
  • Verifiable Results:

    • Results must be reproducible by others.
    • Science relies on solid, measurable evidence.
  • Specificity in Claims:

    • Science makes careful, specific claims based on evidence.
    • Medicine and scientific research require rigorous testing.
  • Accurate Measurements:

    • Quantifiable and precise data is essential.
    • Example: Measurement of gravitational acceleration.

Characteristics of Pseudoscience

  • Fixed Ideas:

    • Relies on dogma, resistant to change despite evidence.
    • Example: Homeopathy and its magical thinking.
  • Lack of Peer Review:

    • No rigorous examination by others; resembles ideology.
  • Selective Evidence:

    • Only favorable findings are highlighted.
    • Example: Marginal effects in acupuncture studies.
  • Resistance to Criticism:

    • Criticism seen as conspiracy against beliefs.
    • Personalization of criticism, lack of openness to being proven wrong.
  • Non-repeatable Results:

    • Claims often based on results that can’t be reproduced.
    • Examples: Healing based on aura or chi.
  • Widespread Claims:

    • Often claim broad effectiveness without evidence.
    • Example: Alternative medicines like shark cartilage.
  • Fuzzy Measurements:

    • Ambiguity and lack of precise data.
    • Dependence on concepts that evade quantification.

Conclusion

  • Science and pseudoscience differ fundamentally in approach and methodology.
  • Emphasized importance of evidence, adaptability, and rigorous testing in science.
  • Pseudoscience is characterized by dogma, lack of transparency, and unverifiable claims.
