This study investigates researcher variability in computational reproduction, an activity for which it is least expected. Eighty-five independent teams attempted numerical replication of results from original policy preferences and immigration. Reproduction were randomly grouped into a ‘transparent group’ receiving code or ‘opaque only method description no code. The transparent group mostly verified (95.7% same sign p -value cutoff), while the opaque had less success (89.3%). Second-decimal...
Economics journals with reproducibility policies are cited more often than others. For the minority of a mandatory and enforced policy, this is significant when controlling for time journal effects. To cope large variety software used to develop standards replicability, joint efforts could ensure each empirical study published data, code, instructions on how use them together. Individual reviewers take initiative by asking replicable results. The American Journal Political Science sets an...
In empirical social sciences research, only a small minority of study material is publicly available, therefore allowing full replication. The number replication studies published in academic journals even smaller. Our wiki documents the results more than 300 replications, so far mainly economics. It includes database 2,600 studies. For each we provide information about availability for This helps instructors to identify practical examples courses focusing on methods or particular topics....
The replication crisis in political science and other social behavioral sciences spawned a credibility revolution, calling for new open research practices that ensure greater transparency, including pre-registrations, data code access. Replications of published are an important element this revolution as part the self-correcting process scientific knowledge production. Simultaneously, replications can be pedagogical tool improving student method skills introducing them to best via...
Introduction The replication crisis in the behavioral and social sciences spawned a credibility revolution, calling for new open science research practices that ensure greater transparency, including preregistrations, data code, access. Statement of Problem Replications published are an important element this revolution as part self-correcting process scientific knowledge production; however, teaching value replications is still underutilized thus far. Literature Review Pedagogical points to...
This paper reports findings from a crowdsourced replication. Eighty-five independent teams attempted computational replication of results reported in an original study policy preferences and immigration by fitting the same statistical models to data. The involved experimental condition. Random assignment put participating into either transparent group that received code, or opaque receiving only methods section, rough description no code. mostly verified numerical with sign p-value threshold...
In an era of mass migration, social scientists, populist parties and movements raise concerns over the future immigration-destination societies. What impacts does this have on policy solidarity? Comparative cross-national research, relying mostly secondary data, has findings in different directions. There is a threat selective model reporting lack replicability. The heterogeneity countries obscures attempts to clearly define data-generating models. P-hacking HARKing lurk among standard...
The Community of Open Scholarship Grassroots Networks (COSGN), includes 120 grassroots networks, representing virtually every region the world and research discipline. These networks communicate coordinate on topics common interest. We propose, using an NSF 19-501 Full-Scale implementation grant, to formalize governance coordination maximize impact establish standard practices for sustainability. In project period, we will increase capacity COSGN advance community goals participating...
