Informal Fallacies of Perspective

← Back to Domain-Specific Families

Abstractions that identify reasoning errors arising from mistaken assumptions about perspective or knowledge, including fallacies projecting present knowledge or feeling onto past or hidden events (historian's fallacy, furtive fallacy, psychologist's fallacy), and related principles about introspection and interpretation (KK thesis, virtuality fallacy, fallacy of accent).

6 abstractions in this family — domain-specific abstractions that sit near one another in structural-signature space (k-means over structural-signature embeddings). Each is shown with its short description.

• Fallacy of accent — The fallacy of accent (also known as accentus, from its Latin denomination, and misleading accent ) is a verbal fallacy that reasons from two different vocal readings of the same written words.
• Furtive fallacy — The furtive fallacy is an informal fallacy of emphasis in which historical outcomes are asserted to be the result of hidden (furtive) misconduct or wrongdoing by decision makers.
• Historian's fallacy — The historian's fallacy is an informal fallacy that occurs when one assumes that decision makers of the past viewed events from the same perspective and having the same information as those subsequently analyzing the decision.
• KK thesis — The KK thesis or KK principle (also known as epistemic transparency or positive introspection) is a principle of epistemic logic which states that "If you know that P is the case then you know that you know that P is the case." This means that one cannot know that P is, if one does not know whether one's knowledge of P is correct.
• Psychologist's fallacy — The psychologist's fallacy is an informal fallacy that occurs when an observer assumes that their subjective experience reflects the true nature of an event.
• Virtuality fallacy — Moor in 2001, is a name given to the informal fallacy of asserting that things which exist in a virtual context are not real, or do not have real effects.
