One of the most common and lethal of ‘modern’ habits of thought or declaration… note that it can be referred to as ‘insufficient sample’ (which can be taken as: the often intentionally biased extension of a derived quality from some specific sample or situation to all members of a class such as ‘most people’, ‘jobs’, ‘women’ or ‘men’).

“A hasty generalization is a fallacy in which a conclusion is not logically justified by sufficient or unbiased evidence. Also called insufficient sample, converse accident, faulty generalization, biased generalization, jumping to a conclusion, secundum quid, and neglect of qualifications.

By definition, an argument based on a hasty generalization always proceeds from the particular to the general.”
