Logical Fallacies in Scientific Context

  • Logical Fallacies undermine scientific thinking including scientific method (methodology)
  • Fallacies involve errors in reasoning: lack evidence or logical coherence.
  • Examples of fallacies: Strawman, Appeal to Authority, Correlation vs. Causation , Confirmation Bias, Ad Hominem, Hasty Generalization, Appeal to Emotion, Cherry-Picking, Argument from Ignorance

Common Logical Fallacies

  • Strawman: Misrepresenting an argument for easier attack.
  • Appeal to Authority: Something is true just because an authority figure says so.
  • Correlation vs Causation: Mistaking correlation for causation.
  • Confirmation Bias: Favouring evidence supporting existing beliefs while ignoring contradictory evidence.
  • Ad Hominem: Attacking the person making the claim instead of the claim itself.
  • Hasty Generalization: Drawing a conclusion based on limited evidence.
  • Appeal to Emotion: Manipulating emotions instead of evidence.
  • Cherry-Picking: Selecting only evidence that supports a claim while ignoring contrary data.
  • Argument from Ignorance: Claiming something is true because it hasn't been disproven, or that it's false because it hasn't been proven.

Conclusion and Key Takeaways

  • Critical thinking evaluates the validity of claims, involving skepticism and objectivity.
  • Scientific methods rely on empirical evidence, falsifiability and logical reasoning.
  • Distinguish between science and pseudoscience.

Essential Takeaways

  • Scientific method developed over many centuries. Key transitions moved from pure philosophy to empirical investigation.
  • Modern science combines scientific, mathematical and empirical methods.
  • Logical fallacies undermine scientific arguments.
  • Recognizing fallacies assists in clear scientific reasoning
  • Understanding history of scientific method helps appreciate the current scientific approach.

Science vs. Pseudoscience

  • Science: Falsifiability, empirical testing, peer review, self-correction
  • Pseudoscience: Resistance to testing, lack of self-correction, appeal to authority

Additional Resources

  • List of resources for further study including books and articles
  • These resources are a valuable complement to the course material.

Remember

  • Critical thinking in science is not about knowing all the answers, but asking the right questions and systematically evaluating evidence.
