Article summary
This article examines why secret police units are staffed by surprisingly mediocre agents, arguing that career incentives in hierarchical security bureaucracies push underperforming officers toward clandestine work. Using biographic records for 4,287 Argentine officers (1975–83), the authors show that low-achieving officials, stuck in lower ranks and facing discharge risk, were more likely to join the secret police—an association tied to career preservation rather than ideology.
