THINKING FOR YOURSELF: CH 11 INDUCTIVE REASONING AND INDUCTIVE FALLACIES





TFY: CH 11 INDUCTIVE REASONING AND INDUCTIVE FALLICIES

Inductive reasoning is a reason to a conclusion about all members of a class on the basis of an examination of a few members of a class. Induction reasons from the particular to the general. Method for researching from personal observation is call empirical or scientific method. The different types of inductive reasoning are:

· Sensory observation: awareness through basic senses of sight, taste, touch, smell, and hearing.

· Enumeration: range of simple counting to gathering statistics.

· Analogical reasoning: a form of comparison, similarities between things that seem different.

· Discovering patterns: look for patterns, note their characteristics, and draw conclusions.

· From and about causes: probable causes of events

· Hypotheses: preliminary conclusion derived from inductive reasoning.

· Statistics: mathematics of the collection, organization, and interpretation of numerical data.

· Probability: the ratio of the number of actual occurrences of a specific event to the total number of possible occurrences.

Inductive fallacies are inductive reasoning gone wrong. Some inductive fallacies are:

· Hasty generalizations: fallacy of over generalizing, drawing a conclusion without enough sampling.

· Either-or fallacy or false dilemma: only two choices when there are actually other options.

· Questionable statistic: fallacy of offering statistics that are unknowable, faulty or misleading

· Contradicting and inconsistencies: making claims or offering evidence that contradict the conclusion.

· Loaded questions: using a biased question in order to obtain a determined result

· False analogy: basing an argument on a comparison of two things that has some similarities, but also have a lot of difference that are ignored.

· False cause: a claiming a connection between events without supporting evidence.

· Slippery slope: arguing without sufficient proof
