I'd like to assign social science undergraduate students an article, short part of a book, or even a blog post about causality and counterfactual logic that is easy to understand.
It seems that most articles and books are too advanced for undergraduate students unfamiliar with advanced philosophy, formal logic, or statistics.
The class is a research methods course for undergraduates, mostly in their first and second years of college, in the social sciences. My background is in econometrics rather than philosophy, so my knowledge of causality and counterfactuals is mostly within the statistical causal inference framework (e.g., Morgan and Winship, Judea Pearl, and Donald Rubin).
For undergraduates with little knowledge of statistics, however, I would not assign the work of these authors. Perhaps instead it would be better to introduce them to causality through a philisophical lens, which itself can become difficult.
Summary: I'm looking for a discussion of causality that is approachable for a more popular audience.
