Why it matters
A finding can be credible where it was measured but less useful elsewhere. Before applying it, compare the people, institutions, conditions and time period.
A worked example
A savings reminder tested among salaried workers may have a different effect among workers with irregular income. The context of application matters.
Illustrative example · simplified assumptionsA common mistake
Applying a study everywhere without checking the population and context.
Where the idea needs care
A well-identified effect in one setting need not transfer unchanged to another. This is distinct from identifying the original causal effect.
Apply the idea
Explain this concept using a different example from your spending, work, business or a policy debate. State what stays fixed and what could change the result.
