Generational Framework Methodology
Twenge's distinctive research method — comparing psychological traits across nationally representative cohorts using consistently-administered longitudinal surveys — which makes visible patterns that individual studies cannot detect and provides the empirical foundation for her arguments about technology's developmental effects.
The generational framework methodology is Twenge's signature research contribution: the systematic comparison of psychological traits, attitudes, and behaviors across American cohorts using large-scale surveys administered consistently over decades. The surveys include Monitoring the Future (administered to high school seniors annually since 1975), the Youth Risk Behavior Surveillance System (administered biennially since 1991), the American Freshman Survey (administered to incoming college students since 1966), and the General Social Survey (administered to adults since 1972). Each survey includes hundreds of thousands of respondents across years. The method's power lies in its breadth and consistency: by comparing responses to identical questions across generations, Twenge can identify when cohorts diverge from historical patterns, and the divergences — when sharp enough and consistent enough across multiple independent datasets — point toward causes.

What distinguishes the generational framework from most psychology research is its scale and temporal depth. Individual studies capture snapshots —
