How does noise generated by researcher decisions undermine the credibility of science? We test this by observing all decisions made among 73 research teams as they independently conduct studies on the same hypothesis with identical starting data. We find excessive variation of outcomes. When combined, the 107 observed research decisions taken across teams explained at most 2.6 of the total variance in effect sizes and 10 of the deviance in subjective conclusions. Expertise, prior beliefs and attitudes of the researchers explain even less. Each model deployed to test the hypothesis was unique, which highlights a vast universe of research design variability that is normally hidden from view and suggests humility when presenting and interpreting scientific findings.

The paper reports findings from a crowdsourced replication. Eighty-four replicator teams attempted to verify results reported in an original study by running the same models with the same data. The replication involved an experimental condition. A “transparent” group received the original study and code, and an “opaque” group received the same underlying study but with only a methods section and description of the regression coefficients without size or significance, and no code. The transparent group mostly verified the original study (95.5%), while the opaque group had less success (89.4%). Qualitative investigation of the replicators’ workflows reveals many causes of non-verification. Two categories of these causes are hypothesized, routine and non-routine. After correcting non-routine errors in the research process to ensure that the results reflect a level of quality that should be present in ‘real-world’ research, the rate of verification was 96.1 in the transparent group and 92.4 in the opaque group. Two conclusions follow: (1) Although high, the verification rate suggests that it would take a minimum of three replicators per study to achieve replication reliability of at least 95 confidence assuming ecological validity in this controlled setting, and (2) like any type of scientific research, replication is prone to errors that derive from routine and undeliberate actions in the research process. The latter suggests that idiosyncratic researcher variability might provide a key to understanding part of the “reliability crisis” in social and behavioral science and is a reminder of the importance of transparent and well documented workflows.

Prior studies have noted several risk and protective factors for school dropout; however, only a few have examined longer-term vulnerabilities alongside temporary risk and protective factors. Consequently, we focused on the role that both stable and time-varying psychosocial risk and protective factors play in dropout intentions and actual dropout, using a 4-year longitudinal design. We investigated to what extent dropout intentions and dropout can be predicted by an interplay between negative life events, general self-efficacy, and perceived social support. We distinguished between time-averaged levels of self-efficacy and social support, and within-person change in self-efficacy and social support over time. This enabled us to establish whether dropout intentions and dropout were sensitive to fluctuations in perceived self-efficacy and social support over time when controlling for person-specific levels of these psychosocial resources. Calculating multilevel models with data from a prospective cohort study (N = 4,956, 43% male), we found that negative life events were significantly associated with an increase in dropout intentions and the likelihood of school dropout. Furthermore, time-averaged levels of self-efficacy and social support, and a within-person (situational) increase in these characteristics relative to their time-averaged levels, were related to lower levels of dropout intentions but did not prevent dropout. The positive relationship between negative life events and dropout intentions was attenuated for individuals who perceived higher levels of self-efficacy than usual. Our findings suggest future research should further investigate time-averaged and situational psychosocial drivers of school dropout in combination. [less ▲]

In an era of mass migration, social scientists, populist parties and social movements raise concerns over the future of immigration-destination societies. What impacts does this have on policy and social solidarity? Comparative cross-national research, relying mostly on secondary data, has findings in different directions. There is a threat of selective model reporting and lack of replicability. The heterogeneity of countries obscures attempts to clearly define data-generating models. P-hacking and HARKing lurk among standard research practices in this area.This project employs crowdsourcing to address these issues. It draws on replication, deliberation, meta-analysis and harnessing the power of many minds at once. The Crowdsourced Replication Initiative carries two main goals, (a) to better investigate the linkage between immigration and social policy preferences across countries, and (b) to develop crowdsourcing as a social science method. The Executive Report provides short reviews of the area of social policy preferences and immigration, and the methods and impetus behind crowdsourcing plus a description of the entire project. Three main areas of findings will appear in three papers, that are registered as PAPs or in process. [less ▲]

Life satisfaction is an important indicator of successful development. However, adolescents’ life satisfaction tends to be relatively unsteady, and environmental influences play a critical role in shaping life satisfaction among adolescents in the transition to young adulthood. Given the paramount importance that education plays in adolescents’ lives, adolescents’ life satisfaction may vary as a function of school-related stress experience. At the same time, coping resources may help reduce adverse effects of stress on life satisfaction. With this in mind, we examined whether, and to what extent, perceived stress in education and general self-efficacy (a resource that facilitates coping) affect the life satisfaction of adolescents in transition to young adulthood. We distinguished between baseline levels of stress and self-efficacy and within-person change in stress and self-efficacy to determine whether life satisfaction is sensitive to fluctuations in stress and self-efficacy when person-specific levels of stress and self-efficacy are taken into account. Estimating growth curve models on data from a panel study on the life trajectories of compulsory-school leavers (n = 5126, 55.3 % female), we found that baseline levels of stress and self-efficacy, as well as within-person change in stress and self-efficacy, affected adolescents’ life satisfaction. Moreover, our results showed that baseline self-efficacy mitigated the negative effect of baseline stress on life satisfaction. These findings improve our understanding of two major psychological determinants of adolescents’ life satisfaction and extend our knowledge of life satisfaction trajectories during the transition to young adulthood.

Drivers of drop-out have been studied extensively over the past years. A number of studies suggest that self-efficacy and social support help reduce adverse effects of significant life events, such as trouble with family and friends, on drop-out intention but also on actual drop- out. However, over-all, evidence as to whether self-efficacy and social support influence drop-out intention and actual drop-out is mixed. We examined whether, and to what extent, perceived social support and general self-efficacy affect drop-out of adolescents in transition to young adulthood. We distinguished between baseline levels of social support and self-efficacy and (within-person) change in social support and self-efficacy in order to determine whether drop-out is sensitive to fluctuations in social support and self-efficacy when person-specific levels of social support and self-efficacy are taken into account. Estimating growth curve models on TREE data, a panel study on the life trajectories of compulsory-school leavers in Switzerland, we found that baseline levels of social support and self-efficacy, as well as within-person change in social support and self-efficacy, affected adolescents’ drop-out intention, but did not prevent actual drop-out. Moreover, our models show effects of a range of significant life events on drop-out intention and actual drop-out. These findings improve our understanding of the role that psychological and social factors play in shaping drop-out intentions and actual drop-out [less ▲]
