Being able to replicate scientific findings is crucial for scientific progress. We replicate 21 systematically selected experimental studies in the social sciences published in Nature and Science between 2010 and 2015. The replications follow analysis plans reviewed by the original authors and pre-registered prior to the replications. The replications are high powered, with sample sizes on average about five times higher than in the original studies. We find a significant effect in the same dire...

Intelligence test scores and educational duration are positively correlated. This correlation could be interpreted in two ways: Students with greater propensity for intelligence go on to complete more education, or a longer education increases intelligence. We meta-analyzed three categories of quasiexperimental studies of educational effects on intelligence: those estimating education-intelligence associations after controlling for earlier intelligence, those using compulsory schooling policy ch...

ABSTRACTMany global settings lack indigenous measures of child development, making the adaptation of available instruments necessary. The aim of this study was to reliably adapt the core subtests of the Wechsler Preschool and Primary Scale of Intelligence-III (WPPSI-III) to assess cognitive abilities in young children in rural Pakistan. A systematic adaptation protocol was followed and psychometric properties were tested after completing data collection on a cohort of 1,273 children at 4 years o...

Abstract It has been argued that Raven's tests are problematic in the context of Sub-Saharan Africa. No discussion of Raven's in South Sudan, one of the least developed countries in Africa, has been presented. We present all known administrations of Raven's to South Sudanese samples. We find that Raven's in South Sudan is problematic. The scores are so low that they may imply that the subjects had little understanding of the test and simply guessed the answers. It is argued that the undeveloped ...

ABSTRACTWe developed a test battery for use among children in Bangladesh, Ghana, and Tanzania, assessing general intelligence, executive functioning, and school achievement. The instruments were drawn from previously published materials and tests. The instruments were adapted and translated in a systematic way to meet the needs of the three assessment contexts. The instruments were administered by a total of 43 trained assessors to 786 children in Bangladesh, Ghana, and Tanzania with a mean age ...

There is a large amount of evidence that groups differ in average cognitive ability. The hereditarian hypothesis states that these differences are partly or substantially explained by genetics. Despite being a positive claim about the world, this hypothesis is frequently equated with racism, and scholars who defend it are frequently denounced as racists. Yet equating the hereditarian hypothesis with racism is a logical fallacy. The present article identifies ten common arguments for why the here...
