Although replication is a central tenet of science, direct replications are rare in psychology. This research tested variation the replicability 13 classic and contemporary effects across 36 independent samples totaling 6,344 participants. In aggregate, 10 replicated consistently. One effect – imagined contact reducing prejudice showed weak support for replicability. And two flag priming influencing conservatism currency system justification did not replicate. We compared whether conditions...
We conducted preregistered replications of 28 classic and contemporary published findings, with protocols that were peer reviewed in advance, to examine variation effect magnitudes across samples settings. Each protocol was administered approximately half 125 comprised 15,305 participants from 36 countries territories. Using the conventional criterion statistical significance ( p < .05), we found 15 (54%) provided evidence a statistically significant same direction as original finding....
Many methods for reducing implicit prejudice have been identified, but little is known about their relative effectiveness. We held a research contest to experimentally compare interventions the expression of racial prejudice. Teams submitted 17 that were tested an average 3.70 times each in 4 studies (total N = 17,021), with rules revising between studies. Eight effective at preferences Whites compared Blacks, particularly ones provided experience counterstereotypical exemplars, used...
Implicit preferences are malleable, but does that change last? We tested 9 interventions (8 real and 1 sham) to reduce implicit racial over time. In 2 studies with a total of 6,321 participants, all immediately reduced preferences. However, none were effective after delay several hours days. also found these did not explicit reliably moderated by motivations respond without prejudice. Short-term malleability in necessarily lead long-term change, raising new questions about the flexibility...

Interpreting a failure to replicate is complicated by the fact that could be due original finding being false positive, unrecognized moderating influences between and replication procedures, or faulty implementation of procedures in replication. One strategy maximize quality involving authors study design. We (N = 17 Labs N 1,550 participants, after exclusions) experimentally tested whether author involvement improved replicability classic from Terror Management Theory (Greenberg et al.,...
<h3>Background:</h3> Total knee replacement (TKR) is a cost-effective treatment option for severe osteoarthritis (OA). While prevalence of OA higher among blacks than whites, TKR rates are lower blacks. Physicians9 implicit preferences might explain racial differences in recommendation. The objective this study was to evaluate whether the magnitude bias predicts physician recommendation black and white patients with assess effectiveness web-based instrument as an intervention decrease effect...
Many Labs 3 is a crowdsourced project that systematically evaluated time-of-semester effects across many participant pools. See the Wiki for table of contents files and to download manuscript.

Replication studies in psychological science sometimes fail to reproduce prior findings. If these use methods that are unfaithful the original study or ineffective eliciting phenomenon of interest, then a failure replicate may be protocol rather than challenge finding. Formal pre-data-collection peer review by experts address shortcomings and increase replicability rates. We selected 10 replication from Reproducibility Project: Psychology (RP:P; Open Science Collaboration, 2015) for which...
Implicit preferences for Whites compared to Blacks can be reduced via exposure admired Black and disliked White individuals ( Dasgupta & Greenwald, 2001 ). In four studies (total N = 4,628), while attempting clarify the mechanism, we found that implicit were weaker in “positive Blacks” condition a control (weighted average d .08). This effect was substantially smaller than original demonstration ; .82). Factors beyond may necessary effect, such as making race accessible during exemplar...
Number of citations and the h-index are popular metrics for indexing scientific impact. These, other existing metrics, strongly related to scientists' seniority. This article introduces complementary indicators that unrelated number years since PhD. To illustrate cumulative career-stage approaches assessing impact across a discipline, 611 scientists from 97 U.S. Canadian social psychology programs amassed analyzed. Results provide benchmarks evaluating career span in disciplines with similar...

While direct replications such as the “Many Labs” project are extremely valuable in testing reliability of published findings across laboratories, they reflect common reliance psychology on single vignettes or stimuli, which limits scope conclusions that can be reached. New experimental tools and statistical techniques make it easier to routinely sample appropriately treat them random factors. We encourage researchers get into habit including multiple versions content (e.g., stimuli...

Many amateur athletes believe that using a professional athlete's equipment can improve their performance. Such be said to affected with positive contagion, which refers the belief of transference beneficial properties between animate persons/objects previously neutral objects. In this experiment, contagion was induced by telling participants in one group putter belonged golfer. The effect examined for perception and performance golf putting task. Individuals who believed they were golfer's...

Abstract Pets play an important role in their owners’ lives and are often viewed as family members. However, research on human-animal relationships suggests that pet owners receive relatively less emotional support when experiencing grief after the death of a beloved pet, phenomenon known disenfranchised grief. In this internet-based survey study, we explored how people experienced surrounding loss pets, experience mirrors emotions result from human loved one. We examined factors such...
In the Human Penguin Project (N = 1755), 15 research groups from 12 countries collected body temperature, demographic variables, social network indices, seven widely-used psychological scales and two newly developed questionnaires (the Social Thermoregulation Risk Avoidance Questionnaire (STRAQ-1) Kama Muta Frequency Scale (KAMF)). They were to investigate relationship between environmental factors (e.g., geographical, climate etc.) human behaviors, which is a long-standing inquiry in...
