A weakness of the study of followership is ______.

A) leadership scholars and followership scholars will never see eye to eye
B) its extreme focus on predictive statistical models
C) followers are not important in real world organizations
D) little empirical research has been conducted on the topic

The given options suggest that the best answer is D, as it is the only choice that reflects a weakness of the study of followership. The option D indicates that little empirical research has been conducted on the topic, which means that there is a lack of scientific evidence and research-based knowledge regarding followership. Hence, it could be considered a weakness of the study of followership. The other options are not valid, as they do not correctly reflect the limitations of the study of followership. For instance, option A is a general statement that may not be true in all cases, and option C is incorrect as followers are crucial for organizational success. Option B's explanation does not relate to followership but rather to statistical models.
