Thinking through uncertainty: Nonconsequential reasoning and choice

  title={Thinking through uncertainty: Nonconsequential reasoning and choice},
  author={Eldar Shafir and Amos Tversky},
  journal={Cognitive Psychology},
When thinking under uncertainty, people often do not consider appropriately each of the relevant branches of a decision tree, as required by consequentialism. As a result they sometimes violate Savage's sure-thing principle. In the Prisoner's Dilemma game, for example, many subjects compete when they know that the opponent has competed and when they know that the opponent has cooperated, but cooperate when they do not know the opponent's response. Newcomb's Problem and Wason's selection task… Expand
Nonconsequential Reasoning and Its Consequences
According to consequentialism, which underlies the rational theory of choice, decisions should be determined by an assessment of the potential consequences. People, however, do not always considerExpand
Uncertainty and the difficulty of thinking through disjunctions
Decision situations that lead to violations of Savage's sure-thing principle are examined, and a variety of simple reasoning problems that often generate confusion and error are reviewed. Expand
Pragmatic approach to decision making under uncertainty: The case of the disjunction effect
The disjunction effect (Tversky & Shafir, 1992) occurs when decision makers prefer option x (versus y) when knowing that event A occurs and also when knowing that event A does not occur, but theyExpand
Nonconsequential Reasoning and Its

The “vanishing” of the disjunction effect by sensible procrastination
The disjunction effect (Tversky and Shafir in Psychol Sci 3:305–309, 1992) occurs when decision makers prefer option x (versus y) when knowing that event A occurs and also when knowing that event AExpand
Evidential reasoning in the prisoner's dilemma.
It is suggested that cooperation can be explained in part by expectations of reciprocal behavior, that is, by the belief that players facing the same situation probably will come to the same decision. Expand
The Disjunction Effect: Does It Exist for Two-Step Gambles?
The findings show that people do not violate the sure thing principle in repeated gambles, and the validity of alleged violations in other paradigms is discussed. Expand
Memory and Anticipation
The introduction of memory imperfections into models of economic decision making creates a natural role for anticipatory emotions. Their combination has striking behavioural implications. The paperExpand
Magical thinking: A representation result
This paper suggests a novel way to import the approach of axiomatic theories of individual choice into strategic settings and demonstrates the benefits of this approach. We propose both a tractableExpand
Focussing in reasoning and decision making
Focussing underlies individuals' attempts to imagine an alternative scenario that avoids an unfortunate ending to a story, and is shown how the focussing bias can be reduced by certain experimental manipulations. Expand


The Disjunction Effect in Choice under Uncertainty
One of the basic axioms of the rational theory of decision under uncertainty is Savage's (1954) sure-thing principle (STP) It states that if prospect x is preferred to y knowing that Event AExpand
Rational choice and the framing of decisions
Alternative descriptions of a decision problem often give rise to different preferences, contrary to the principle of invariance that underlines the rational theory of choice. Violations of thisExpand
Counterfactuals and Two Kinds of Expected Utility
We begin with a rough theory of rational decision-making. In the first place, rational decision-making involves conditional propositions: when a person weighs a major decision, it is rational for himExpand

Newcomb's Problem and Prisoners' Dilemma
The relationship between Newcomb's problem, which involves an apparent paradox of prediction, and Prisoners' Dilemma is explicated. After describing a resolution to Newcomb's problem, due to John A.Expand
Natural Reasons: Personality and Polity
This book is about the rationality of decisions. Hurley argues the position that the philosophy of mind is strongly relevant and connected both to ethics and jurisprudence. The book constitutes aExpand
An experiment was performed to determine whether the use of realistic materials would improve performance in a deceptive reasoning problem. The task involved selecting from a set of envelopes thoseExpand
Causal versus diagnostic contingencies: On self-deception and on the voter's illusion.
Abstract : Two experiments were conducted to test the notion that people select actions that are diagnostic of favorable outcomes even though the actions do not cause those outcomes. In the firstExpand
Extensional versus intuitive reasoning: the conjunction fallacy in probability judgment
Perhaps the simplest and the most basic qualitative law of probability is the conjunction rule: The probability of a conjunction, P (A&B) cannot exceed the probabilities of its constituents, P (A)Expand
Facilitation of reasoning by realism: Effect or non‐effect?
A series of five experiments was performed comparing abstract and thematic materials in Wason's (1966) selection task. The first was designed to test the effect of negated rule components on theExpand
