Inductive reasoning refers to drawing conclusions based on patterns or trends in observed data points rather than relying on a comprehensive set of facts. It involves making generalizations starting from specific individual cases. While inductive arguments can vary in strength based on how well the premises support the conclusion, induction alone does not constitute a valid proof because the conclusion may not apply to all cases, even if it has been observed to apply in many specific examples. The document provides examples of inductive reasoning arguments regarding characteristics that could be assumed about individuals based on common patterns or trends observed in their professions or activities.
