# Partition-edit-count: naive extensional reasoning in judgment of conditional probability.

@article{Fox2004PartitioneditcountNE, title={Partition-edit-count: naive extensional reasoning in judgment of conditional probability.}, author={Craig R. Fox and Jonathan Levav}, journal={Journal of experimental psychology. General}, year={2004}, volume={133 4}, pages={ 626-42 } }

The authors provide evidence that people typically evaluate conditional probabilities by subjectively partitioning the sample space into n interchangeable events, editing out events that can be eliminated on the basis of conditioning information, counting remaining events, then reporting probabilities as a ratio of the number of focal to total events. Participants' responses to conditional probability problems were influenced by irrelevant information (Study 1), small variations in problem…

Partition Priming in Judgments of Imprecise Probabilities

- Psychology
- 2009

On grounds of insufficient reason, a probability of 1/K is assigned to K mutually exclusive possible events when nothing is known about the likelihood of those events. Fox and Rottenstreich (2003)…

Another chance for good reasoning

- PhilosophyPsychonomic bulletin & review
- 2017

The results strongly disconfirm the hypothesis that natural frequencies are a privileged cognitive representational format for Bayesian inferences and suggest that a significant portion of laypeople adequately handle genuine single-event probability problems once these are rendered computationally more accessible by using numbers of chances.

Between ignorance and truth: Partition dependence and learning in judgment under uncertainty.

- PsychologyJournal of experimental psychology. Learning, memory, and cognition
- 2006

Judged probabilities reflected a compromise between the frequency with which each attribute appeared and the ignorance prior probability cued by the number of distinct values that the focal attribute could take on, and were partition dependent.

Assigning Subjective Probabilities to Event Trees: Partition Dependence and Bias Toward the Ignorance Prior

- Economics

Decision and risk analysts have considerable discretion in designing procedures for eliciting subjective probabilities. One popular approach is to specify a particular set of exclusive and exhaustive…

Using statistical reasoning performance to reveal information parsing preferences in the mind

- Psychology, Computer ScienceQuarterly journal of experimental psychology
- 2015

These results favour an ecological rationality perspective and the associated frequency and individuation hypotheses regarding statistical reasoning (i.e., a privileged status for frequency representations to guide parsing of objects, events, and locations into easily countable units).

How Many Alternatives? Partitions Pose Problems for Predictions and Diagnoses

This paper focuses on one matter that poses a problem for both human judges and standard probability frameworks, namely the assumption of a unique (privileged) and complete partition of the…

Subjective Probability Assessment in Decision Analysis: Partition Dependence and Bias Toward the Ignorance Prior

- EconomicsManag. Sci.
- 2005

This work shows that assessed probabilities are systematically biased toward a uniform distribution over all events into which the relevant state space happens to be partitioned, so that probabilities are "partition dependent" and related research on the "pruning bias" in fault-tree assessment is related.

Sets or frequencies? How to explain the facilitation effect in conditional probability problems

- Psychology

Since the '70s, the Heuristics and Biases Program in Cognitive Psychology has shown that people do not reason correctly about Bayesian or conditional probability problems. In the '90s, however,…

Effects of Temporal and Causal Schemas on Probability Problem Solving

The claim made here is that problem solving in probability is particularly affected by domain-specific knowledge in probabilistic reasoning.

Naive probability: a mental model theory of extensional reasoning.

- PhilosophyPsychological review

The theory predicts several phenomena of reasoning about absolute probabilities, including typical biases, and explains how naive reasoners can infer posterior probabilities without relying on Bayes's theorem.

Partition Priming in Judgment Under Uncertainty

It is shown that likelihood judgments are biased toward an ignorance-prior probability that assigns equal credence to each mutually exclusive event considered by the judge, and systematic partition dependence is observed.
