research_objective: Test cross-culturally whether high vs low stakes affect knowledge ascription in a Bank-case
vignette, and assess whether null results are due to ineffective stakes manipulation or protagonist projection.

objective: Test whether stakes affect knowledge attribution in a Bank-case vignette across 19 cultural/linguistic
sites; site-level estimates are extracted as effects.
