The relationship between performance and ability is a central concern in the social sciences: Are the most successful much more able than others, and are failures unskilled? Prior research has shown that noise and self-reinforcing dynamics make performance unpredictable and lead to a weak association between ability and performance. Here we show that the same mechanisms that generate unpredictability imply that extreme performances can be relatively uninformative about ability. As a result, the highest performers may not have the highest expected ability and should not be imitated or praised. We show that whether higher performance indicates higher ability depends on whether extreme performance could be achieved by skill or requires luck.regression to the mean | randomness | social learning | performance evaluation | ecological rationality E xtreme performance attracts people's attention. People tend to believe the most successful are the most skillful and that failures lack skill (1, 2). A tendency to imitate the most successful has also been argued to be a basic universal trait that is shaped by evolution and promotes adaptiveness (3, 4). However, is success necessarily an indication of skill and worthy of praise and imitation and failure an indication of lack of skill?Clearly, observed performance is not always a reliable indicator of skill. Chance events outside the control of individuals often influence performance (5-7). Moreover, such chance events rarely average out over time. Instead, due to "rich-get-richer" dynamics and "Matthew effects" (8), success usually breeds success and failure breeds failure. For example, individuals with early success might be given more resources and instruction, or consumers may favor products with a high market share (9, 10). Prior research has shown how such processes can amplify chance events and produce a weak association between performance and ability (11-13), leading to a distribution of outcomes that is both unpredictable and highly unequal (14). In such settings, extreme success and failure are, at best, only weak signals of skill. The highest performers may be more able than others and the lowest performers less able than others, but one should not expect their skill level to be very far from the mean (15).These prior contributions show that performance and skill may be weakly associated due to noise and rich-get-richer dynamics, but they do not challenge the idea that higher performers are likely more skilled and worthy of imitation. Even if the highest performers are only marginally more skilled than others, it makes sense to imitate them. In this paper, we show that noise and richget-richer dynamics can have more counterintuitive implications that go beyond the conventional understanding of regression to the mean. Noise and rich-get-richer dynamics not only introduce unpredictability but also change how much one can learn from extreme performances and whether higher performance indicates higher skill. In particular, we show that when noise and rich-getricher dy...
W e propose that random variation should be considered one of the most important explanatory mechanisms in the management sciences. There are good theoretical reasons to expect that chance events strongly impact organizational behavior and outcomes. We argue that models built on random variation can provide parsimonious explanations of several important empirical regularities in strategic management and organizational behavior. The reason is that random variation in a structured system can give rise to systematic patterns at the macro level. Here, we define the concept of a chance explanation; describe the theoretical mechanisms by which random variation generates patterns at the macro level; outline how key empirical regularities in management can be explained by chance models; and discuss the implications of chance models for theoretical integration, empirical testing, and management practice.
It is not insignificant that seminal contributions to management scholarship have highlighted luck as an alternative explanation for performance differences between individuals and organizations. Yet it has rarely taken center-stage in scholarship. The principal purpose of this paper is to provide a systematic review of the application of luck in the management literature and in such foundation disciplines as economics, sociology, and psychology. Our analysis finds five common perspectives on luck: (a) luck as Attribution; (b) luck as Randomness; (c) luck as Counterfactual; (d) luck as Undeserved; and (e) luck as Serendipity. We outline various ways in which research on luck may be advanced along each of these perspectives, and develop an underexplored, sixth, perspective on (f) 'luck as Leveler' to provide a possible solution to such issues as social inequality and (unwarranted) executive compensation.
Objective: This study aims to explore the multilevel mediation effects of cognitive emotion regulation strategies (CERS) on the link between neuroticism and depressive symptoms among Chinese adolescents. Method: A total of 1,265 Chinese adolescents were surveyed using the Chinese version of the Cognitive Emotion Regulation Questionnaire (CERQ-C), the neuroticism scale of the Chinese children's version of the Eysenck Personality Questionnaire (EPQ-Ck), and the Chinese Children's Depressive symptoms Inventory (CDI-C). Partial correlation analyses, multigroup confirmatory factor analyses, and structural equation modeling were used. Results: (1) Neuroticism had significant, positive correlations with maladaptive CERS strategies (self-blame, acceptance, rumination, catastrophizing, and other-blame) and depressive symptoms (ps < 0.001). Adaptive CERS strategies (positive refocusing, refocus on planning, positive reappraisal, and putting into perspective) had significant, negative correlations with neuroticism and depressive symptoms (ps < 0.001). (2) Neuroticism and CERS strategies significantly predicted depressive symptoms. CERS strategies played partially mediating roles in the relationship between adolescents' neuroticism and depressive symptoms. Conclusion: CERS strategies have partial multilevel mediation effects on the link between neuroticism and depressive symptoms.
