How would you describe a person who inhibits others from sharing their ideas?

A person who inhibits others from sharing their ideas is best described as authoritarian. This term refers to a leadership or interpersonal style where control is exercised over individuals or groups, often leading to an environment where open communication and collaboration are stifled. In an authoritarian setting, the individual tends to make decisions unilaterally and does not encourage input or feedback from others, which directly impacts the sharing of ideas.

While a cooperative atmosphere fosters teamwork and idea exchange, and a democratic approach actively involves everyone in discussions and decision-making, an authoritarian stance restricts such interactions. Being flexible typically suggests adaptability and openness to new ideas, which contrasts with the behavior of inhibiting contributions. Thus, the correct descriptor for someone who stifles idea-sharing aligns with the characteristics of an authoritarian style.
