When given a desirable item, people have a tendency to value this owned item more than an equally-desirable, unowned item. Conversely, when the endowed item is undesirable, in some circumstances people have a tendency to swap it for an equally undesirable item, a phenomenon known as the reversed endowment effect. The fact that the endowment effect can reverse for undesirable items has been taken as evidence against loss aversion being the underlying cause of the endowment effect. This study represents the first time that the reversed endowment effect has been observed for choices with real consequences. However, we find that the reversed endowment effect occurs only when participants’ ability to compare the available choice options is limited. We further show that these endowment reversals can also be induced for choices between desirable options and removed for choices between undesirable options by manipulating the expectations participants have when making a choice. Finally, we show that our data, including endowment reversals, can in principle be explained by loss aversion.

People are more likely to endorse statements of the form "A is more than B" than those of the form "B is less than A", even though the ordinal relationship being described is identical in both cases -– a result I dub the "more-credible" effect. This paper reports 9 experiments (total N = 5643) that probe the generality and basis for this effect. Studies 1–4 replicate the effect for comparative statements relating to environmental change and sustainable behaviours, finding that it is robust to changes in participant population, experimental design, response formats and data analysis strategy. However, it does not generalize to all stimulus sets. Studies 5–9 test the proposition that the effect is based on the greater ease of processing "more than" statements. I find no meaningful effect of warning people not to base their judgments on the fluency of the sentences (Studies 5 and 6), but do find associations between comparative language, credibility, and processing time: when the more-credible effect manifests, the more-than statements are read more quickly than the less-than statements, and this difference partly mediates the effect of comparative on agreement with the statements; in contrast, for a set of comparisons for which changes in the more/less framing did not affect truth judgments, there was no meaningful difference in the time taken to read the more- and less-than versions of the statements. Taken together, these results highlight the importance of comparative language in shaping the credibility of important socio-political messages, and provide some limited support for the idea that the effect of language choice is partly due to differences in how easily the statements can be processed -– although other mechanisms are also likely to be at work.

This article argues that we need to move beyond the “Atlantic” and “formal” bias in our understanding of the history of slavery. It explores ways forward toward developing a better understanding of the long-term global transformations of slavery. Firstly, it claims we should revisit the historical and contemporary development of slavery by adopting a wider scope that accounts for the adaptable and persistent character of different forms of slavery. Secondly, it stresses the importance of substantially expanding the body of empirical observations on trajectories of slavery regimes, especially outside the Atlantic, and most notable in the Indian Ocean and Indonesian Archipelago worlds, where different slavery regimes existed and developed in interaction. Thirdly, it proposes an integrated analytical framework that will overcome the current fragmentation of research perspectives and allow for a more comparative analysis of the trajectories of slavery regimes in their highly diverse formal and especially informal manifestations. Fourth, the article shows how an integrated framework will enable a collaborative research agenda that focuses not only on comparisons, but also on connections and interactions. It calls for a closer integration of the histories of informal slavery regimes into the wider body of existing scholarship on slavery and its transformations in the Atlantic and other more intensely studied formal slavery regimes. In this way, we can renew and extend our understandings of slavery's long-term, global transformations.

This essay traces the development of China–India studies from the mid-nineteenth century to the present in order to take stock of the field, which has witnessed a surge in publication over the past two decades. The assessment presented here weaves the main shifts in China–India political relations with the emergence of various strands of China–India scholarship, since the two aspects often intersect. The major lacuna in the field, this essay argues, is a framework needed to analyze the complex connections and the pertinent comparisons between China and India. It contends that research on China–India topics should ideally attempt to combine comparative and connective frameworks with analyses that transcend geographic, temporal, and disciplinary boundaries to address this lacuna.

This paper addresses how to think about the permissibility of introducing deadweight costs (so-called ‘ordeals’) on candidate recipients of goods in order to attain better outcomes. The paper introduces some distinctions between different kinds of value dimensions that should be taken into account when such judgements are made and draws from the literature on comparisons across different value dimensions in order to canvas what sort of situations one might arguably face when evaluating ordeals. In light of the distinctions drawn and the possibilities canvassed, the paper proceeds to outline what circumstances indicate which of the possible situations one is in.

On the basis of dissociated and scattered skull bones and several types of scutes and scales of a single, large-sized individual, a new species of dercetid is recorded from the lower to middle portion of the Maastricht Formation (upper Gronsveld, Schiepersberg or Emael members) as formerly exposed at ’t Rooth quarry near Bemelen, east of Maastricht, the Netherlands. This new taxon, Pelargorhynchus grandis n. sp., the fifth dercetid recorded to date from the type area of the Maastrichtian Stage, is characterised by the presence of both large, smooth scutes and small ornamented scales, by the degree of curvature of skull bones, the presence of unfused premaxillae and the lack of teeth.
