Critical Thinking
Critical thinking contributes to a satisfying existence.
Principles of critical thinking include:
• independent confirmation of information
• substantive debate by knowledgeable proponents of all points of view
• in science, there are no “authorities” who are infallible
• test fairly and quantitatively more than one hypothesis
• if two hypotheses explain the data equally well, usually the simpler is correct
When discussing issues avoid:
• ad hominem comments
• argument from authority
• argument from adverse consequences
• appeal to ignorance
• special pleading
• begging the question (aka assuming the answer)
• observational selection (counting the hits and ignoring the misses)
• misunderstanding of statistics
• non sequitur
• post hoc, ergo propter hoc — “It happened after, so it was caused by”
• meaningless question
• false dichotomy — considering only the two extremes in a continuum of possibilities
• confusion of correlation and causation
• straw man — caricaturing a position to make it easier to attack
• suppressed evidence or half-truths
• weasel words
