Which of the following best defines a pioneer?

A pioneer is best defined as a leader in a field. This term refers to individuals who are the first to explore new territory or who are at the forefront of innovation and progress in a particular area. They are characterized by their initiative and willingness to take risks to create or discover new concepts, practices, or technologies.

In contrast, a supporter of existing theories would not fit the definition of a pioneer, as they tend to uphold and promote established ideas rather than forge new paths. Similarly, a critic of new ideas does not align with the concept of pioneering, as they typically focus on challenging or opposing innovations rather than leading and innovating themselves. Lastly, being a follower in a specific career implies a passive role, which stands in stark opposition to the active, trailblazing nature of a pioneer. A pioneer is inherently about leading the way and making impactful contributions to their field.
