Inductive Flashcards
FALLACIES OF EXCEPTION // Accident
arguing from the general to the particular and failing to apply a relevant exception
“A fruit salad should be made with fruit;
tomato is a fruit;
therefore tomato can go in a fruit salad”
FALLACIES OF EXCEPTION // Converse Accident
arguing from an particular exception to a general principle; apply an exception to the rule inappropriately
“Lawyers are allowed to practice law, therefore anyone should be allowed to practice law!”
FALLACIES OF EXCEPTION // Overwhelming Exception
a valid generalisation, with an exception so broad it undermines the general rule
“‘i’ before ‘e’, except after ‘c’.”
FALLACIOUS CONCLUSION SCOPE // Hasty Generalisation
Jumping to Conclusions
drawing conclusions from an insufficient sample/evidence
A = P
B = P
therefore C, D, E… = P
“Every German I’ve met has blue eyes, therefore all Germans have blue eyes.”
FALLACIOUS CONCLUSION SCOPE // Hasty Generalisation // Anecdotal
Fallacy of Misleading Vividness
drawing a conclusion from an anecdotal experience
“My uncle smoked 20 a day and lived to 95, so clearly it’s not as bad as they say.”
FALLACIOUS CONCLUSION SCOPE // Slothful Induction
failing to acknowledge a justified generalisation; explaining away by other, improbable explanations
“Michael has had ten car crashes in the last six months, yet refuses to accept the conclusion that he’s a bad driver”
