Syllabus: How to Read Psychological Science
Trace the comparisons across populations and empirical domains, asking how each supports or limits the overall argument about generalization. The complete target article is journal pp. 61–83; the accompanying commentaries and authors' response are separate, optional works.
Why you’re reading it. Make the population implied by a psychological claim explicit, and inspect whether the evidence supports that generalization.
A question to consider. Return to the bystander experiment. What population and setting does its evidence directly concern, and what would you need before generalizing the finding to emergencies across societies?
Why this reading
Even a well-controlled experiment does not establish how widely its result generalizes. This synthesis makes the population behind a psychological claim part of the evidence to inspect. Its examples challenge the habit of treating convenient university samples as an unexamined stand-in for humanity.
Before you read
WEIRD abbreviates Western, Educated, Industrialized, Rich, and Democratic. It describes a sampling problem, not a set of uniform psychological types. The selected work is the target article; the journal’s accompanying commentaries are separate, optional works.
Read for
- Follow one domain closely: what varies, who was compared, and how comparable were the measures?
- Separate evidence of a population difference from an explanation of that difference.
- Ask which claims require representative sampling and which require a more specific generalization argument.
- Examine the authors' proposed changes to research practice.
Consider afterwards
- Choose a familiar psychological claim. What population does its wording imply, and what sample supports it?
- How would you distinguish cultural variation from differences in task interpretation or measurement?
Editorial context
The paper makes a methodological case for checking generalizability; it does not show that every effect differs across societies. Its broad labels can also hide variation within countries and communities. Use the particular comparisons to evaluate the argument, and avoid substituting a Western/non-Western binary for an explicit account of populations, settings, and measures.
