Complex Question (Plurium Interrogationum)

Also Known As: Plurium Interrogationum Many Questions Fallacy Fallacy of Presupposition
Informal Fallacy ID: complex_question

Definition

The complex question fallacy (plurium interrogationum) bundles two or more questions into one, with an embedded presupposition that constrains possible answers. Unlike a simple loaded question which presupposes one fact, a complex question entangles multiple issues so that answering any single one implicitly addresses others. The respondent cannot address the components separately.

Examples

"Where did you hide the money you stole from the company?" (This bundles three presuppositions: that money is missing, that the respondent took it, and that the respondent hid it.)

A reporter asks a politician: 'When did you stop accepting bribes from lobbyists?' The question presupposes that the politician accepted bribes and that they have stopped — both unestablished claims embedded in a single unanswerable yes/no question.

A survey asks consumers: 'How much has our revolutionary new product improved your daily routine?' This presupposes the respondent uses the product, that it has improved their routine, and that the improvement is notable — all bundled into one leading question.

Verification Steps
Verification Steps
Binary yes/no questions that an AI must answer to detect a reasoning pattern in a text.
Each of the 452 aspects has verification steps — simple yes/no questions designed to systematically detect whether a pattern appears in a text. For ad hominem: "Does the argument attack a person rather than their claim?" For false dichotomy: "Are only two options presented when more exist?" This ensures consistent, reproducible analysis.

Binary (yes/no) questions an LLM must answer to identify this aspect:

  1. 1

    Does the question assume the truth of an unproven claim?

    Type: binary
  2. 2

    Are two or more questions being combined into one?

    Type: binary
  3. 3

    Can the question be answered without implicitly accepting the presupposition?

    Type: binary

The Deep Dive section provides in-depth information about each aspect: a real-world example showing the pattern in action, an explanation of why it works psychologically, practical advice on how to counter it, alternative names, and links to related aspects.
