Many of the NSA’s ISTJs were eclectic geeks just this side of Rain Man. One was known to park his car in exactly the same spot in the agency parking lot every day—no matter whether the lot was empty—and then walk precisely the same steps from that parking spot to his office. Another would buy secondhand pants, wear them every day to work for two weeks, and then throw them out and buy another pair, so that he never had to do laundry. In addition to this disarming weirdness, there was a dark side to the predominance of this singular personality type within the agency. The introverts at the NSA never questioned authority. They kept to themselves and remained silent about the agency’s secrets, for good or ill. Many NSA employees were married to other NSA employees, and often their children came to work there as well, reinforcing the agency’s insular nature, enhanced by its geographic isolation at Fort Meade in suburban Maryland, far from the rest of official Washington.
