Concerns about the veracity of psychological research have been growing. Many findings in science are based on studies with insufficient statistical power and nonrepresentative samples, or may otherwise be limited to specific, ungeneralizable settings populations. Crowdsourced research, a type large-scale collaboration which one more projects conducted across multiple lab sites, offers pragmatic solution these other current methodological challenges. The Psychological Science Accelerator...

Failures to replicate evidence of new discoveries have forced scientists ask whether this unreliability is due suboptimal implementation methods or presumptively optimal are not, in fact, optimal. This paper reports an investigation by four coordinated laboratories the prospective replicability 16 novel experimental findings using rigour-enhancing practices: confirmatory tests, large sample sizes, preregistration and methodological transparency. In contrast past systematic replication...
According to cognitive-dissonance theory, performing counterattitudinal behavior produces a state of dissonance that people are motivated resolve, usually by changing their attitude be in line with behavior. One the most popular experimental paradigms used produce such change is induced-compliance paradigm. Despite its popularity, replication crisis social psychology and other fields, as well methodological limitations associated paradigm, raise concerns about robustness classic studies this...
Can interventions meaningfully increase intelligence? If so, how? The Database of Raising Intelligence is a continuously updated compendium randomized controlled trials that were designed to intelligence. In this article, the authors examine nearly every available intervention involving children from birth kindergarten, using meta-analytic procedures when more than 3 studies tested similar methods and reviewing too few for meta-analysis. This yielded 4 meta-analyses on effects dietary...

Abstract Given how commonly GPS is now used in everyday navigation, it surprising little research has been dedicated to investigating variations its use and such may relate navigation ability. The present study investigated general dependence, people report using various navigational scenarios, the relationship between these measures spatial abilities (assessed by self-report ability learn layout of a novel environment). dependence an individual’s perceived need usage frequency with which...
We view kids these days unfavorably, especially on traits at which we excel, partly because have a biased of the past.
Our basic beliefs about reality can be impossible to prove and yet we feel a strong intuitive conviction them, as exemplified by insights that imbue an idea with immediate certainty. Here presented participants worldview such "people's core qualities are fixed" simultaneously elicited aha moment. In the first experiment (N = 3000, which included direct replication), rated truer when they solved anagrams also experienced moments. A second 1564) showed statement moment must perceived for this...
Abstract: Background: The Psychological Science Accelerator (PSA) recently completed a large-scale moral psychology study using translated versions of the Oxford Utilitarianism Scale (OUS). However, have no validity evidence. Objective: investigated structural evidence OUS across 15 and produced version-specific reports. Methods: We analyzed data from PSA, which was collected internationally on centralized online questionnaire . also qualitative feedback experts for each version. Results:...
Consent forms are a cornerstone of ethical research, required part nearly any study. Important information about the study and risks given in plain view for participants to read agree before conducting research. In online studies, consent form is not participants, but presented them, Meaning, they can skip it. We test whether likely seven studies across three different panels 7,378 people. Using both conservative liberal criteria, we find between 6 8.9% could plausibly forms, 17.8% have...
Abstract Using modern hunter-gatherers to infer about early Homo sapiens only works if at least (a) represent an unbiased sample of humanity, and (b) act in ways similar the behavior . Both these are false, leading problem whether we can draw conclusions from hunter-gatherers.
Terror Management Theory (TMT) proposes that when people are made aware of their own death, they more likely to endorse cultural values. TMT is a staple social psychology, being featured prominently in textbooks and the subject much research. The implications associated with significant, as its advocates claim it can partially explain conflicts, intergroup antagonisms, even war. However, considerable ambiguity regarding effect size exists, no preregistered replication death-thought...
Big Team Science involves multiple sites of independent research labs from potentially all over the world coming together to run same study. The power with which these studies tackle issues replicability and generalizability are unprecedented in Psychological science. Here, we discuss new places can go on top investigating generalizability. 1) leverage collective intelligence identify that foundational specific theories test them; 2) data collection capabilities numerous collect hard reach...

We attempted to replicate a self-affirmation intervention that produced 40% reduction in the academic achievement gap among at-risk students. The was designed as protection against stereotype threat—, which creates stress and suppresses performance, engagement, learning of students stereotyped intellectually inferior. In previous research, Black Hispanic who engaged values-affirmation exercise significantly improved their performance over course school semester. these salutary effects both...
Measurement involves numerous theoretical and empirical steps—ensuring our measures are operating the same in different groups is one step. invariance occurs when factor loadings item intercepts or thresholds of a scale operate similarly for people at level latent variable groups. This commonly assumed to mean measuring thing those Here we test assumption extending measurement common by randomly assigning American adults ( N = 1500) fill out scales assessing coherent (search meaning life)...
