Building upon previously developed and more general dual‐process models, this paper provides empirical support for a multidimensional thinking style construct comprised of linear thinking and multiple dimensions of nonlinear thinking. A self‐report assessment instrument (Linear/Nonlinear Thinking Style Profile; LNTSP) is presented and preliminarily tested across three studies with an overall sample of 778 respondents comprised of business students and managers. The results indicate that nonlinear thinking style consists of seven distinct, yet interrelated dimensions: intuition, creativity, values, imagination, flexibility, insights, and emotions. Convergent and discriminant validity estimates vis‐à‐vis a multidimensional creative thinking index and an emotional intelligence measure provide support for further development of the instrument. The implications of these results for future managerial cognition research are discussed, as well as potential practical applications of the LNTSP for management education and business practice.
