Final answer:
Ineffective leaders typically have poor communication skills, lack integrity, and cannot motivate others, but having strong decision-making abilities is not a characteristic of ineffectiveness in leadership. Understanding that leadership effectiveness may vary with the followers' needs and the context is crucial.
Step-by-step explanation:
Ineffective leaders, according to research, commonly exhibit several negative traits, but strong decision-making abilities are not one of them. The characteristics of ineffective leaders, except for one, include poor communication skills, lack of integrity, and an inability to motivate others. Conversely, strong decision-making abilities are a characteristic of effective leadership.
It is important to understand that leadership styles may vary depending on the followers' individual characteristics, such as their degree of extroversion and individual need for growth. Different leadership styles include democratic, laissez-faire, and authoritarian, each having its own potential effectiveness depending on the context and individuals involved. Recognizing the right style to employ in a given situation is a key aspect of successful leadership.
