Common mistakes in Philosophy and critical thinking
Six reasoning traps and how to spot them.

Reasoning mistakes appear in politics, consumer choices and family conversations. Recognizing them is more useful than memorizing fallacy names as labels for opponents.
Mistake 1: treating popularity as proof
Thousands of shares do not establish the accuracy of a claim. A video may spread because it provokes fear, surprise or laughter. Locate its original source and check whether the evidence supports what the caption says; reach is not reliability.
Mistake 2: attacking a person instead of a claim
A questionable history does not by itself disprove someone’s proposal. Source credibility may matter, particularly for testimony, but data, assumptions and consequences still need analysis. Respond to the actual argument.
Mistake 3: imagining only two possible choices
“Work longer hours or the company will fail” may ignore changes to process, scope or pricing. List plausible alternatives before accepting the dilemma. Not every alternative will be feasible, but that must be investigated rather than assumed.
Mistake 4: confusing correlation with causation
Two trends can move together by coincidence, because of a shared cause or because one affects the other. Before claiming causation, examine timing, plausible mechanisms and factors that have not been controlled.
Mistake 5: selecting confirming examples
Once a view feels settled, supporting stories become easier to notice than counterexamples. Deliberately seek the strongest case against your hypothesis. If no conceivable evidence could change your mind, the inquiry may have stopped.
Mistake 6: demanding impossible certainty
Some decisions must be made before complete evidence exists. That does not make every guess equally sound. Compare likely harms and available evidence, state the unknowns and avoid presenting confidence as a substitute for reasoning.
Application: price and quality
Imagine someone claiming the most expensive product must be best. Its price is measurable, but “best” needs criteria such as durability, service, features and purpose. Compare products that solve the same problem and acknowledge that different users can reasonably prefer different options.
Discussion improves when people test the reasoning before judging the person who disagrees.
