- Poisoning the well
Poisoning the well (or attempting to poison the well) is a
logical fallacy where adverse information about a target is pre-emptively presented to anaudience , with the intention of discrediting or ridiculing everything that the target person is about to say. Poisoning the well is a special case of argumentum ad hominem, and the term was first used with this sense byJohn Henry Newman in his work "Apologia Pro Vita Sua ". [ [http://www.philosophicalsociety.com/Logical%20Fallacies.htm Philosophical society.com - Logical Fallacies] ]In general usage, poisoning the well is the provision of "any" information that may produce a biased result. For example, if a woman tells her friend, "I think I might buy this beautiful dress", then asks how it looks, she has "poisoned the well", as her previous comment could affect her friend's response.
tructure
A poisoned-well "argument" has the following form::1. Unfavorable information (be it true or false) about person A (the target) is presented by another. ("Before you listen to my opponent, may I remind you that he has been in jail."):2. Any claims person A then makes will be regarded as false, or taken less seriously.
