A Method for Fallacy Identification
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
Identifying a fallacy means stating the conclusion and the support offered, asking whether that support bears on it, naming the gap, then checking whether context makes the instance legitimate.
First example. A senator's tax proposal should be rejected because the senator was twice divorced. Step one, the conclusion: reject the proposal. Step two, the support: facts about the senator's marriages. Step three: does that bear on whether the proposal is sound? No — its merits are unchanged by who advanced it. Step four, name the gap: the argument attacks the person, not the position. Step five, the near-miss check: could a person's history ever be relevant? Yes, if the question were whether to trust their unverified testimony. It is not, so the verdict stands. Second example. This medication is safe because a clinical pharmacologist reviewed the trial data and says so. Steps one and two are quick. Step three: does the support bear on the conclusion? Here it does. Step five matters most — an appeal to a genuine expert, speaking inside their field, on a question their field settles, is not a fallacy. Acquitted.
Step five separates analysis from fallacy-spotting as a reflex. Most fallacy names describe a move that is legitimate in some contexts, and skipping the near-miss check turns the catalogue into a way of dismissing arguments by matching their shape rather than assessing their support.
