Most theories in the social sciences are verbal and provide ordinal-level predictions for data. For example, a theory might predict that performance is better in one condition than another, but not by how much. One way of gaining additional specificity is to posit many ordinal constraints that hold simultaneously. For example a theory might predict an effect in one condition, a larger effect in another, and none in a third. We show how common theoretical positions naturally lead to multiple ordinal constraints. To assess whether multiple ordinal constraints hold in data, we adopt a Bayesian model comparison approach. The result is an inferential system that is custom-tuned for the way social scientists conceptualize theory, and that is more intuitive and informative than current linear-model approaches.

A key goal in research is to use data to assess competing hypotheses or theories. Analternative to the conventional significance testing is Bayesian model comparison. The mainidea is that competing theories are represented by statistical models. In the Bayesianframework, these models then yield predictions about data even before the data are seen.How well the data match the predictions under competing models may be calculated, andthe ratio of these matches—the Bayes factor—is used to assess the evidence for one modelcompared to another. We illustrate the process of going from theories to models and topredictions in the context of two hypothetical examples about how exposure to media affectsattitudes toward refugees.

Many Labs projects have become the gold standard for assessing the replicability of key findings in psychological science. The Many Labs 4 project recently failed to replicate the mortality salience effect where being reminded of one’s own death strengthens the own cultural identity. Here, we provide a Bayesian reanalysis of Many Labs 4 using meta-analytic and hierarchical modeling approaches and model comparison with Bayes factors. In a multiverse analysis we assess the robustness of the results with varying data inclusion criteria and prior settings. Bayesian model comparison results largely converge to a common conclusion: We find evidence against a mortality salience effect across the majority of our analyses. Even when ignoring the Bayesian model comparison results we estimate overall effect sizes so small (between d = 0.03 and d = 0.18) that it renders the entire field of mortality salience studies as uninformative.

The need for a relevant and instrumental body of knowledge that can secure the taskof historical reconstruction in Muslim societies originally inspired the da’wa for the Islamizationof knowledge. The immediate targets for this da’wa were the social sciences for obvious reasons.Their field directly impinges on the organization of human societies and as such carries intothe area of human value and belief systems. The fact that such a body of knowledge alreadyexisted and that the norms for its disciplined pursuit were assumed in the dominant practiceconfronted Muslim scholars with the context for addressing the issues at stake. How relevantwas current social science to Muslim needs and aspirations? Could it, in its present formand emphasis, provide Muslims with the framework for operationalizing their values in theirhistorical present? How instrumental is it in shaping the social foundations vital for the Muslimfuture? Is instrumentality the only criteria for such evaluations? In seeking to answer thesequestions the seeds are sown for a new orientation in the social sciences. This orientationrepresents the legitimate claims and aspirations of a long silent/silenced world culture.In locating the activities of Muslim social scientists today it is important to distinguishbetween two currents. The first is in its formative stages as it sets out to rediscover the worldfrom the perspective of a recovered sense of identity and in terms of its renewed culturalaffinities. Its preoccupations are those of the Muslim revival. The other current is constitutedof the remnants of an earlier generation of modernizers who still retain a faith in the universalityof Western values. Demoralized by the revival, as much as by their own cultural alientation,they seek to deploy their reserves of scholarship and logistics to recover lost ground. Bymodifying their strategy and revalorizing the legacy they hope that, as culture-brokers, theymight be more effective where others have failed. They seek to pre-empt the cultural revivalby appropriating its symbols and reinterpreting the Islamic legacy to make it more tractableto modernity. They blame Orientalism for its inherent fixations and strive to redress its selfimposedlimitations. Their efforts may frequently intersect with those of the Islamizing current,but should clearly not be confused with them. For all the tireless ingenuity, these effortsare more conspicuous for their industry than for their originality. Between the new breadof renovationists and the old guard of ‘modernizers’, the future of an Islamic Social Scienceclearly lies with the efforts of the former.Within the Islamizing current it is possible to distinguish three principal trends. The firstopts for a radical perspective and takes its stand on epistemological grounds. It questionsthe compatibility of the current social sciences on account of their rootedness in the paradigmof the European Enlightenment and its attendant naturalistic and positivist biases. Consistencedemands a concerted e€fort to generate alternative paradigms for a new social science fromIslamic epistemologies. In contrast, the second trend opts for a more pragmatic approachwhich assumes that it is possible to interact within the existing framework of the disciplinesafter adapting them to Islamic values. The problem with modern sciene is ethical, notepistemological, and by recasting it accordingly, it is possible to benefit from its strengthsand curtail its derogatory consequences. The third trend focuses on the Muslim scholar, rather ...
