Are we facing a “causality crisis” in acculturation research? The need for a methodological (r)evolution

Acculturation is an inherently causal phenomenon that deals with changes and processes initiated by intercultural contact. However, although more than 13,000 scientific articles to date have been published on a topic related acculturation, only small fraction uses data allow for inferences. As result, our field can be seen as facing “crisis of causality,” where central theories models assume causality between constructs still lack robust empirical support. To address this gap, I provide recommendations the next generation acculturation research, emphasizing primarily need experimental longitudinal studies.
