What is a common assumption about pygmalion-prone coaches?

Pygmalion-prone coaches are often characterized by their fixed beliefs about athlete traits. This notion stems from the Pygmalion effect, which posits that higher expectations can lead to improved performance due to the belief in an athlete's potential. However, these coaches may overlook the adaptability and growth of their athletes due to their rigid perspectives. They might assume athletes are inherently capable or incapable based on preconceived notions, thus failing to recognize individual progress or the need for tailored coaching approaches.

In contrast, other options highlight characteristics such as belief in improvement, flexibility, or encouragement of diverse methods, which do not align with the narrow viewpoint typically associated with Pygmalion-prone coaching. Such openness to change or variation in training would indicate a more growth-oriented mindset rather than the fixed mindset suggested by the correct choice.
