This research describes the results of a national survey of entrepreneurial mindset conducted with 3,194 randomly selected individuals in a representative national sample. Several other measures of entrepreneurial personal characteristics appear in the literature. These include the Entrepreneurial Attitude Orientation measure (cf. EAO, Robinson, Stimpson, Huefner, & Hunt, 1991), the General Enterprising Tendency (cf. GET2, Caird, 1990), the test of Entrepreneurial Self-efficacy (cf. Chen, Greene, & Crick, 1998), and the Entrepreneurial Mindset Profile (cf. EMP, Davis, Hall, & Mayer, 2016). Valuable as these measures are, each has important limitations. This comprehensive study successfully addressed nearly all of those limitations.
