While some authors, such as Shane (2009), argue that the innovative startup model should be prioritized in entrepreneurship research and public policy because of its growth potential and consequent economic impact, other scholars who are references in the field take a different position. This is the case, for example, of Aldrich and Ruef (2018), Kuratko and Audretsch (2022), and Kuckertz, Scheu, and Davidsson (2023). These authors express concern about the bias that entrepreneurship research has developed by leaving aside most ventures and entrepreneurs while emphasizing startups and high-growth firms. In this sense, it is timely that this issue of RELISE addresses the diversity of types of entrepreneurship and entrepreneurial learning. Considering diversity means recognizing that entrepreneurship manifests itself in forms other than the creation of technology-based startups. In the next section, some expressions of this diversity are presented, followed by an exploration of the possible social and scientific costs of ignoring diversity in entrepreneurship.
