The military has been interested in the so-called "spidey sense" or intuition for at least 200 years. In his classic treatise "On War," von Clausewitz (first published in 1832) spoke of intuition and its importance in decision making in tactical situations. Recently, studying and identifying characteristics of intuitive behavior has become popular because having and using this "spidey sense" could be advantageous for identifying threatening situations. To study the behavior, we must first define it. A widely accepted definition is that intuition is a subconscious preliminary perception of a pattern or meaning, most commonly experienced as a gut feeling that biases thoughts and decisions (Volz & von Cramon, 2006). Researchers have studied intuition from many perspectives. Some researchers are looking for behavioral indicators of intuition to test intuitive decision making abilities (Frederick, 2002; Bowers, Regeher, & Balthazard, 1990). Other researchers use self-report inventories to assess preference for using intuition (Pacini & Epstein, 1999; Betsch, 2008). A weakness of this work is the lack of integration between these various methods of assessing intuition. In this study, we combine the behavioral and preference measures of intuition along with individual differences measures (i.e., working memory capacity task, personality inventory, and a test of observation and clear thinking) to examine characteristics of people who display intuitive behaviors. Intuitive individuals in our study performed better on the test of observation and clear thinking, had a lower degree of "agreeableness" as a personality characteristic, and indicated that they were more rational when making decisions. While this is a preliminary investigation into capturing the essence of "spidey sense," these results help us to understand the underlying characteristics of intuition and more investigation into this topic may help us to train our war fighters to sense when danger is lurking.
