Abstract We study the behavioral link between NFL players’ off-field misconduct and their on-field infractions by matching a comprehensive dataset of players’ off-field arrests with detailed record of on-field penalty calls. Results from Poisson regressions indicate that players with arrest record are likewise observed to have significantly higher tendencies for aggression-related penalties, implying their inherent preferences toward risks or aggression. Such association is particularly salient among repeat offenders. We also find that repeat offenders boast stronger overall career performance and longer career span compared to non-offenders and one-time offenders, suggesting that the related behavioral traits can be instrumental to job performance in professional football.

The relative state model posits two nonindependent pathways to risk. The need-based pathway suggests people take risks when nonrisky options are unlikely to meet their needs. The ability-based pathway suggests people take risks when they possess resources or abilities making them more capable of successfully “pulling off” risk-taking. Growing laboratory and field evidence supports need-based risk-taking. However, little is known about ability-based risk-taking. We examined whether three indicators of embodied capital (attractiveness, cognitive ability, and physical dexterity) were associated with risk-related personality traits, risk-attitudes, behavioral risk-taking, and outcomes associated with risk-taking. Among 328 community members recruited to maximize variance on risk-propensity, we demonstrate that embodied capital indices predict various instantiations of risk-propensity consistent with the relative state model.

Abstract. The Balloon-Analogue Risk Task (BART; Lejuez et al., 2002 ) is one of the most popular behavioral tasks suggested to assess risk-taking in the laboratory. Previous research has shown that the conventionally computed score is predictive, but neglects available information in the data. We suggest a number of alternative scores that are motivated by theories of risk-taking and that exploit more of the available data. These scores can be grouped around (1) risk-taking, (2) task performance, (3) impulsive decision making, and (4) reinforcement sequence modulation. Their theoretical rationale is detailed and their validity is tested within the nomological network of risk-taking, deviance, and scholastic achievement. Two multivariate studies were conducted with youths (n = 435) and with adolescents/young adults (n = 316). Additionally, we tested formal models suggested for the BART that decompose observed behavior into a set of meaningful parameters. A simulation study with parameter recovery was conducted, and the data from the two studies were reanalyzed using the models. Most scores were reliable and differentially predictive of criterion variables and may be used in basic research. However, task specificity and the generally moderate validity do not warrant use of the experimental paradigm for diagnostic purposes.

Abstract. The study reports results regarding the dimensionality and construct validity of a newly developed, objective, video-based personality test that assesses the willingness to take risks in traffic situations. On the basis of the theory of risk homeostasis developed by Wilde, different traffic situations with varying degrees of objective danger were filmed. During the test the respondents are asked to indicate at which point the action that is contingent on the described situation will become too dangerous to carry out. Latencies at the item level were recorded as a measure for the subjectively accepted degree of a person's willingness to take risks in the sense of the risk homeostasis theory by Wilde. In a study on 274 people with different educational levels and gender, the unidimensionality of the test as corresponding to the latency model by Scheiblechner was investigated. The results indicate that the Vienna Risk-Taking Test - Traffic assesses a unidimensional, latent personality trait that can be interpreted as subjectively accepted degree of risk (target risk value).
