Laboratory power-differential experiments can isolate structural causes of intergroup behavior.

Evidence

The experimental paradigm offers an efficient, controlled way to simulate and manipulate key structural attributes and measure the human response. Experiments engineering power or status differentials in the lab (e.g., Molm, 1988; Ridgeway, 2001) have been productive and offer great promise. — , Rudman, Laurie A - On the Nature of…, 686
