	Direct group (n = 54)	Waiting group (n = 52)
Distrust in information gathering relative to the cost of waiting	0.93	–
Remaining uncertainty regarding an attack	0.15	–
Minimizing the risk with a better operational picture	–	0.79
Acceptable to take a cost for additional information	–	0.27
Other reasons	0.30	0.12
