Gettier

A Gettier is a correct buzz on a question made by a player who arrived at the answer through an incorrect thought process of a certain sort: they correctly determined that a clue corresponded to the right answer, but were mistaken about how. The term is named for the "Gettier problem" of American philosopher Edmund Gettier, who introduced them to challenge the definition of knowledge on "justified true belief". Making a Gettier is called Gettiering.

Gettiering is not to be confused with fraud, which relies on binary word association and poor clue selection but ultimately relies on accurate deductions. Gettiering specifically describes getting a question right through an incorrect thought process.

Justified true belief and the Gettier problem

Prior to Gettier's work, knowledge could be defined as "justified true belief". In this framework, a subject can be said to know a piece of information P if:

1. P is true
2. they believe that P is true
3. and they have a justification for believing that P is true

The Gettier problem is an example of a situation where a question refers to getting the question right through an incorrect thought process that observers may not necessarily consider 'knowledge.'

Examples

An example of Gettiering a question may be buzzing on a question on "birds" on a clue on the Sibley-Ahlquist Taxonomy based on the knowledge that there is a famous Sibley bird guide. While this would be a good buzz, the Sibley of the taxonomy (Charles Sibley) is not the same as the Sibley of the bird guide (David Allen Sibley). In the case of this question, the player has a justified true belief about the name Sibley and its association with birds, however they have knowledge of the incorrect Sibley. Thus, despite getting the question right and getting the points, they have been rewarded for false knowledge.

Nevertheless, the most common reason for Gettiers is faulty reasoning on the part of the player.
