Once they have observed information, hindsight-biased agents fail to remember how ignorant they were initially; “they knew it all along.” We formulate a theoretical model of this bias, providing a foundation for empirical measures and implying that hindsight-biased agents learning about volatility will underestimate it. In an experiment involving 66 students from Mannheim University, we find that hindsight bias reduces volatility estimates. In another experiment, involving 85 investment bankers…

New technologies for visualizing and understanding data sets may have the unintended consequence of heightening hindsight bias, but an intervention that encourages people to consider alternative causal explanations for a given outcome can reduce hindsight bias.
Second-order Beliefs and the Individual Investor
In a panel survey of individual investors, we show that investors’ second-order beliefs—their beliefs about the return expectations of other investors—influence investment decisions. Investors who
Loss Averse Preferences, Performance, and Career Success of Institutional Investors
Using survey-based measures of mutual fund manager loss aversion, we study the effects of institutional investor preferences on their investment decisions, performance, and career outcomes. We find
On the Failure of Hindsight-Biased Principals to Delegate Optimally
It is shown that the hindsight bias can lead to inefficient delegation decisions and that hindsight-biased subjects more frequently fail to delegate optimally than subjects whom the authors have classified as not hindsight biased.
The Effect of Investor Bias and Gender on Portfolio Performance and Risk
We survey 84 finance and accounting majors to determine the behavioral factors that males and females exhibit when making investment decisions. The survey results are linked to student performance in
Behavioral biases in economic and financial knowledge: Are they the same for men and women?
Contemporary research documents various psychological aspects of economic thought and decision-making. The main goal of our study is to analyze the role of the hindsight bias (Fischhoff [20]) and the


Hindsight Bias and Investment Performance
Once they have observed information, hindsight biased agents fail to remember how ignorant they were initially. This bias has been amply documented by the psychological literature. To study its
Hindsight bias in economic expectations: I knew all along what I want to hear.
The results support the notion that hindsight bias is a reconstruction bias in which self-serving tendencies can influence the reconstruction selectively for favorable and unfavorable outcomes.
Do Biases in Probability Judgment Matter in Markets? Experimental Evidence
Microeconomic theory typically concerns exchange between individuals or firms in a market setting. To make predictions precise, individuals are usually assumed to use the laws of probability in
Judgmental Overconfidence, Self-Monitoring and Trading Performance in an Experimental Financial Market
We measure the degree of overconfidence in judgment (in the form of miscalibration, i.e., the tendency to overestimate the precision of one’s information) and self-monitoring (a form of attentiveness
The Curse of Knowledge in Economic Settings: An Experimental Analysis
In economic analyses of asymmetric information, better-informed agents are assumed capable of reproducing the judgments of less-informed agents. We discuss a systematic violation of this assumption
First Impressions Matter: A Model of Confirmatory Bias
Psychological research indicates that people have a cognitive bias that leads them to misinterpret new information as supporting previously held hypotheses. We model such confirmatory bias in a
Do professional traders exhibit myopic loss aversion? An experimental analysis
Two behavioral concepts, loss aversion and mental accounting, have recently been combined to provide a theoretical explanation of the equity premium puzzle. Recent experimental evidence suggests that
Information Projection: Model and Applications
This paper introduces the concept of such information projection and provides a simple but widely applicable model that describes a novel agency conflict in a frictionless learning environment and applications to defensive medicine are discussed.
Motivational interpretations of hindsight bias: An individual difference analysis
When individuals learn the outcome of an event or the correct answer to a question, they overestimate its prior predictability: that is, they tend to believe they “knew it all along.” Cognitive and
Overconfidence and trading volume
Theoretical models predict that overconfident investors will trade more than rational investors. We directly test this hypothesis by correlating individual overconfidence scores with several measures
