Curiosity is often included as one of several attributes comprising the entrepreneurial mindset. While research on curiosity has been conducted in the field of psychology for many decades, applied research on the construct in the entrepreneurship and entrepreneurship education settings has been lacking.

Many unanswered questions remain about how the various dimensions of curiosity apply to the entrepreneurship education context.
