Biases in casino betting: The hot hand and the gambler’s fallacy
Journal Title: Judgment and Decision Making - Year 2006, Vol 1, Issue 1
Abstract
We examine two departures of individual perceptions of randomness from probability theory: the hot hand and the gambler’s fallacy, and their respective opposites. This paper’s first contribution is to use data from the field (individuals playing roulette in a casino) to demonstrate the existence and impact of these biases that have been previously documented in the lab. Decisions in the field are consistent with biased beliefs, although we observe significant individual heterogeneity in the population. A second contribution is to separately identify these biases within a given individual, then to examine their within-person correlation. We find a positive and significant correlation across individuals between hot hand and gambler’s fallacy biases, suggesting a common (root) cause of the two related errors. We speculate as to the source of this correlation (locus of control), and suggest future research which could test this speculation.

Using hierarchical Bayesian methods to examine the tools of decision-making
Hierarchical Bayesian methods offer a principled and comprehensive way to relate psychological models to data. Here we use them to model the patterns of information search, stopping and deciding in a simulated binary com...
Causal explanations affect judgments of the need for psychological treatment
Knowing what event precipitated a client’s abnormal behaviors makes the client appear more normal than if the event is not known (Meehl, 1973). Does such knowledge also influence judgments of the need for psychological t...
Does telling white lies signal pro-social preferences?
The opportunity to tell a white lie (i.e., a lie that benefits another person) generates a moral conflict between two opposite moral dictates, one pushing towards telling the truth always and the other pushing towards he...
Processing of recognition information and additional cues: A model-based analysis of choice, confidence, and response time
Research on the processing of recognition information has focused on testing the recognition heuristic (RH). On the aggregate, the noncompensatory use of recognition information postulated by the RH was rejected in sever...
