As a good practice, conducting a replication study of any form should begin with a rigorous selection process of the study to be replicated (Brandt, et al., 2014). So many recipes make for a successful replication, and for a project as such CREP study for Africa (CPA), selecting a study to replicate should be a rigorous process. Hence, we provide detailed description of the CPA study selection process. Onset of this selection process, our search for the CPA study begins with identifying recently published 28 articles, 27 of which are found in Psychological Science and one from PsyArxiv based on a number of selection criteria, we considered studies with nonAfrican sample or reported few African samples, Altmetric score rating (although this criteria counts for little), study pre-registered (all studies considered are pre-registered), studies with p value < .01, feasibility (if it is ethically acceptable, especially for African population), at least moderately generalizable and relevant, and preferably with less complex study design. Although most of the 28 articles initially identified met some of these criteria, we ended up with top 4 articles. To further scrutinize the feasibility of these top 4 articles, we sourced for these articles’ research materials available online and reached out to the corresponding authors for other materials we could not find. All the corresponding authors were magnanimous enough to provide some of the material requested. Research materials and information collected include: links to OSF pages, test instruments, analysis plan and scripts, instrument administration sequence, programming software(if applicable), hypothesis and method adopted, and data file. With all research materials obtained, we dropped one of the articles. Although, it must be noted that this article was dropped not for lack of research materials but to allow for a more efficient assessment of the remaining three articles (see uploaded “Effects search” document). The three shortlisted articles were: Article 1: Beyond Purity: Moral Disgust Toward Bad Character Article 2: Specks of Dirt and Tons of Pain: Dosage Distinguishes Impurity From Harm Article 3: Experiential or Material Purchases? Social Class Determines Purchase Happiness To allow our African collaborators contribute to the decision making process for the CPA replication study selection, we then conducted a study assessment survey (see uploaded Qualtrics format of study assessment survey) in which our African collaborators responded to some of the key measures which include Study familiarity, Study interest (as per the researchers, countries and Africa), study relevance (as per the researchers, countries and Africa), study adaptability, effect applicability, and choice of study for replication. Responses were collated for analysis (see uploaded analysis script) and a written report was presented for final selection (see uploaded study assessment report document). Reference Brandt, M.
