Cultural values are often used to categorise groups, e.g. individualism versus collectivism. Often when cultural values are measured, etic scales are used without giving attention to cultural value nuances, e.g. different types of collectivism. An example of a nuanced cultural value is found in the interpretation of ubuntu as a context-specific presentation of collectivism in South Africa. In this article, which may be viewed as an instance of experimental philosophy, the concept of ubuntu will be introduced based on the work (...) of the philosopher Thaddeus Metz by focusing on the distinct aspects of harmonious relationships of identity and solidarity. The theoretical basis was used to develop and validate the Metzian Ubuntu Inventory (MUI) with a sample of 316 respondents. This scale consists of nine items, and has reliability and validity in the South African context. In the conclusion, possible applications of the MUI are suggested. (shrink)

A key challenge in experimental social science research is the incentivisation of subjects such that they take the tasks presented to them seriously and answer honestly. If subject responses can be evaluated against an objective baseline, a standard way of incentivising participants is by rewarding them monetarily as a function of their performance. However, the subject area of experimental philosophy is such that this mode of incentivisation is not applicable as participant responses cannot easily be scored along a true-false spectrum (...) by the experimenters. We claim that experimental philosophers’ neglect of and claims of unimportance about incentivisation mechanisms in their surveys and experiments has plausibly led to poorer data quality and worse conclusions drawn overall, potentially threatening the research programme of experimental philosophy in the long run. As a solution to this, we propose the adoption of the Bayesian Truth Serum, an incentive-compatible mechanism used in economics and marketing, designed for eliciting honest responding in subjective data designs by rewarding participant answers that are surprisingly common. We argue that the Bayesian Truth Serum (i) adequately addresses the issue of incentive compatibility in subjective data research designs and (ii) that it should be applied to the vast majority of research in experimental philosophy. Further, we (iii) provide an empirical application of the method, demonstrating its qualified impact on the distribution of answers on a number of standard experimental philosophy items and outline guidance for researchers aiming to apply this mechanism in future research by specifying the additional costs and design steps involved.

The finding that intuitions about the reference of proper names vary cross-culturally was one of the early milestones in experimental philosophy. Many follow-up studies investigated the scope and magnitude of such cross-cultural effects, but our paper provides the first systematic meta-analysis of studies replicating. In the light of our results, we assess the existence and significance of cross-cultural effects for intuitions about the reference of proper names.
