The Washington State Patrol is 100 years old this year. Demographically it doesn’t look a whole lot different than when it started. The vast majority of troopers patrolling the state’s highways are still white and male. In recent years, one stage in the hiring process has drawn particular scrutiny: the psychological evaluation.
