Incentivization very weakly improves theory of mind
Loss aversion is not robust
From strong exceptions to parameter spaces
The effect of incentivization on the conjunction fallacy in judgments
Revisiting the effect of incentivization on cognitive reflection
The effect of performance‐based incentives on judgment biases is a controversial issue. A recent extensive meta‐analysis of Brañas‐Garza et al. (2019, https://doi.org/10.1016/j.socec.2019.101455 ) found no effect of incentives on performance in the cognitive reflection test (CRT), a test commonly used for assessing heuristic versus deliberative judgments. We conducted a meta‐analysis of studies that directly compared an incentive versus no‐incent…
Choice rates are independent from perceived patterns (when patterns are not obvious)

Who's biased? A meta-analysis of buyer-seller differences in the pricing of lotteries
The Seller's Sense
Previous work comparing pricing decisions by buyers and sellers has primarily focused on the endowment effect, the phenomenon that selling prices exceed buying prices. Here, we examine whether pricing decisions by buyers and sellers also vary in sensitivity to differences between objects' expected values (EVs). Both a loss‐aversion account (which posits that losses are weighted more heavily than gains) and a loss‐attention account (which posits i…
Super‐Underweighting of Rare Events with Repeated Descriptive Summaries
Field studies suggest that providing summarized information concerning the prevalence of risks can increase risk taking when the hazard is rare. We study a simple experimental model of this phenomenon based on repeated descriptive summaries of past outcomes. Under cumulative prospect theory and experience‐sampling models, descriptions of rare events should increase the weighting of rare events. On the other hand, if individuals are sensitive to t…
Losses as modulators of attention
It has been shown that in certain situations losses exert a stronger effect on behavior than respective gains, and this has been commonly explained by the argument that losses are given more weight in people's decisions than respective gains. However, although much is understood about the effect of losses on cognitive processes and behavior, 2 major inconsistencies remain. First, recent empirical evidence fails to demonstrate that people avoid in…
Obesity and risk taking. A male phenomenon
Losses Induce Consistency in Risk Taking Even Without Loss Aversion
It is posited that because of the attentional effect of losses, individuals would show more behavioral consistency in risk‐taking tasks with losses, even in the absence of loss aversion. In two studies, the consistency of risky choices across different experience‐based tasks was evaluated for gain, loss, and mixed (gain loss) tasks. In both studies, losses facilitated the consistency across tasks: the correlation between risk‐taking choices in di…
Loss aversion in the eye and in the heart
The common view in psychology and neuroscience is that losses loom larger than gains, leading to a negativity bias in behavioral responses and Autonomic Nervous System (ANS) activation. However, evidence has accumulated that in decisions under risk and uncertainty individuals often impart similar weights to negative and positive outcomes. We examine the role of the ANS in decisions under uncertainty, and its consistency with the behavioral respon…
Similar processes despite divergent behavior in two commonly used measures of risky decision making
Performance on complex decision-making tasks may depend on a multitude of processes. Two such tasks, the Iowa Gambling Task (IGT) and Balloon Analog Risk Task (BART), are of particular interest because they are associated with real world risky behavior, including illegal drug use. We used cognitive models to disentangle underlying processes in both tasks. Whereas behavioral measures from the IGT and BART were uncorrelated, cognitive models reveal…
On the robustness of description and experience based decision tasks to social desirability
We compared the sensitivity of two classes of decision tasks to social desirability: description‐based tasks and experience‐based tasks. Participants completed a battery of decision tasks in two conditions: a Control condition in which they were asked to perform their best, and an Impression condition in which they were required to impress judges in the context of hiring decisions. The Impression condition was predicted to elicit relatively lower…
Loss aversion, diminishing sensitivity, and the effect of experience on repeated decisions
Three experiments are presented that explore the assertion that loss aversion and diminishing sensitivity drive the effect of experience on choice behavior. The experiments are focused on repeated choice tasks where decision makers choose repeatedly between alternatives and get feedback after each choice. Experiments 1a and 1b show that behavioral tendencies that were previously interpreted as indications of loss aversion in decisions from experi…
The effect of foregone payoffs on underweighting small probability events
Foregone payoffs add information about the outcomes for alternatives that are not chosen. The present paper examines the effect of foregone payoffs on underweighting rare but possible events in repeated choice tasks. Previous studies have not demonstrated any long-lasting effects of foregone payoffs (following repeated presentation of a task) when foregone payoffs do not add much information. The present paper highlights the conditions and the co…
Individual differences in the response to forgone payoffs
This study evaluates the effect of forgone payoffs in decision-making tasks used for studying individual differences. We investigate whether the disclosure of forgone payoffs (defined as payoffs associated with un-chosen alternatives) has selective effects for drug abusers. Evidence suggests that drug abusers are hypersensitive to signals of positive reward. Accordingly, because the forgone payoffs of risky high-variability options include reward…
The Role of Personal Experience in Contributing to Different Patterns of Response to Rare Terrorist Attacks
An examination of the behavioral effect of repeated terrorist attacks reveals that local residents (of the attacked area) appear to be much less sensitive to this risk than international tourists. Furthermore, the limited sensitivity on the part of local residents seems to diminish with time, even when the attacks continue. An experimental study shows a similar pattern in a laboratory experiment that focuses on a basic decision task: when making …
