Final answer:
A person with a collaborative mindset is unlikely to believe that working alone is more efficient, as collaboration is generally associated with generating innovative ideas and attaining successful outcomes.
Step-by-step explanation:
A person with a collaborative mind is not likely to believe that 'Working alone is more efficient' as this contradicts the foundational principles of collaboration which emphasize that sharing ideas and teamwork can lead to innovation and contribute to success. The effort to build a collaborative team involves excellent communication skills, creating trust, and being open, forthcoming, and transparent. Despite the challenges that teams may face, the collaboration is seen as a way to foster creativity and achieve greater outcomes, as suggested by both practical experience and psychological research.
