We conducted replications of 100 experimental and correlational studies published in three psychology journals using high-powered designs and original materials when available. Replication effects were half the magnitude of original effects, representing a substantial decline. Ninety-seven percent of original studies had statistically significant results. Thirty-six percent of replications had statistically significant results; 47% of original effect sizes were in the 95% confidence interval of the replication effect size; 39% of effects were subjectively rated to have replicated the original result; and if no bias in original results is assumed, combining original and replication results left 68% with statistically significant effects. Correlational tests suggest that replication success was better predicted by the strength of original evidence than by characteristics of the original and replication teams.</dcterms:abstract> <dc:creator>Stieger, Stefan</dc:creator> <bibo:uri rdf:resource=""/> <dc:contributor>Kuhlmann, Tim</dc:contributor> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dc:date rdf:datatype="">2016-02-17T07:18:02Z</dc:date> <dc:creator>Nosek, Brian A.</dc:creator> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dspace:isPartOfCollection rdf:resource=""/> <dcterms:isPartOf rdf:resource=""/> <dcterms:available rdf:datatype="">2016-02-17T07:18:02Z</dcterms:available> <dc:contributor>Stieger, Stefan</dc:contributor> <dcterms:title>Estimating the reproducibility of psychological science</dcterms:title> </rdf:Description> </rdf:RDF>
