    Psychology should generalize from—not just to— Africa
    (2022-05-20) Adetula, Adeyemi; Forscher, Patrick; Basnight-Brown, Dana; Azouaghe, Soufian; IJzerman, Hans
    When psychologists attend to Africa, they usually test whether theories and concepts developed in North America and Europe generalize to Africa. Psychology would be enriched by focusing on Africa on its own terms.

    Synergy Between the Credibility Revolution and Human Development in Africa
    (2021-06-21) Adetula, Adeyemi; Forscher, Patrick; Basnight-Brown, Dana; Azouaghe, Soufian; Ouherrou, Nihal; Charyate, Abdelilah; Hansen, Nina; Adetula, Gabriel, Agboola; IJzerman, Hans
    Spurred by a crisis in their confidence in past findings, psychology in North America, Europe, and Australia has been undergoing a credibility revolution, which has spurred the development and popularization of open science practices to improve the research process. Alongside this development, a broad array of stakeholders have noted that African science is at its own crossroads, as investments in this sector can facilitate human development on the continent. Here we argue that these two movements can facilitate each other: psychology in North America and Europe can benefit from stronger psychology research communities on the African continent, while African scientists can benefit from credible evidence generated through open, freely-available open science practices and tools. However, this synergy will only materialize if a wide array of stakeholders invest in African science through providing resources, training, and specially adapted research tools while simultaneously avoiding ethical pitfalls such as corruption and research colonialism.

    Improving the generalizability of psychology findings to a culture requires sampling participants in that culture. Yet psychology studies rarely sample from African populations, even though it represents 17% of the overall world population. This study aimed to conduct an African-led replication study to test whether Rottman and Young’s “mere-trace” hypothesis of moral reasoning (that people are more sensitive to the dosage of harm-based transgressions than purity transgressions) extends to several African communities. We used a training method developed by the Collaborative Replication and Education Project (CREP) to support and train 23 African collaborators. During this process, we conducted a paradigmatic replication of Rottman’s and Young’s test of the mere trace hypothesis in Egypt, Malawi, Morocco, Mozambique, Nigeria, South Africa, and Tanzania. [We did not find/We found] evidence for the main interaction effect (bdomain x dose = xxx) of transgression severity on the moral wrongness judgment of impure and harmful violations. [We did/ However, we did not] replicate Rottman and Young's findings among Africans. This project helped improve the research capacity of our participating African sites and will support other researchers in collaborating with African scholars.
