Failures to replicate evidence of new discoveries have forced scientists to ask whether this unreliability is due to suboptimal implementation of optimal methods or whether presumptively optimal methods are not, in fact, optimal. This paper reports an investigation by four coordinated laboratories of the prospective replicability of 16 novel experimental findings using current optimal practices: high statistical power, preregistration, and complete methodological transparency. In contrast to past systematic replication efforts that reported replication rates averaging 50%, replication attempts here produced the expected effects with significance testing (p<.05) in 86% of attempts, slightly exceeding maximum expected replicability based on observed effect size and sample size. When one lab attempted to replicate an effect discovered by another lab, the effect size in the replications was 97% that of the original study. This high replication rate justifies confidence in rigor enhancing methods and suggests that past failures to replicate may be attributable to departures from optimal procedures.
Research into the authenticity of facial emotion expressions often focuses on the physical properties of the face while paying little attention to the role of beliefs in emotion perception. Further, the literature most often investigates how people express a pre-determined emotion rather than what facial emotion expressions people strategically choose to express. To fill these gaps, this paper proposes a non-verbal zero-sum game – the Face X Game – to assess the role of contextual beliefs and strategic displays of facial emotion expression in interpersonal interactions. This new research paradigm was used in a series of three studies, where two participants are asked to play the role of the sender (individual expressing emotional information on his/her face) or the observer (individual interpreting the meaning of that expression). Study 1 examines the outcome of the game with reference to the sex of the pair, where senders won more frequently when the pair was comprised of at least one female. Study 2 examines the strategic display of facial emotion expressions. The outcome of the game was again contingent upon the sex of the pair. Among female pairs, senders won the game more frequently, replicating the pattern of results from study 1. We also demonstrate that senders who strategically express an emotion incongruent with the valence of the event (e.g., smile after seeing a negative event) are able to mislead observers, who tend to hold a congruent belief about the meaning of the emotion expression. If sending an incongruent signal helps to explain why female senders win more frequently, it logically follows that female observers were more prone to hold a congruent, and therefore inaccurate, belief. This prospect implies that while female senders are willing and/or capable of displaying fake smiles, paired-female observers are not taking this into account. Study 3 investigates the role of contextual factors by manipulating female observers’ beliefs. When prompted to think in an incongruent manner, these observers significantly improve their performance in the game. These findings emphasize the role that contextual factors play in emotion perception—observers’ beliefs do indeed affect their judgments of facial emotion expressions.
Social psychology took an early interest in stereotypes. But it also took a rather narrow interest. Research and theory have been overwhelmingly concerned with negative stereotypes. Positive stereotypes were commonly referenced in definitions of stereotypes, but seldom received any empirical or theoretical attention. We are pleased that a paper on the effects of positive stereotypes, our paper, was chosen for replication in the 2014 special issue of the journal Social Psychology.Our finding that positive stereotypes can boost performance has been documented many times in many laboratories and with many participant groups (e.g., Bargh,
