What is a common characteristic of a demagogue in politics?

A demagogue is typically characterized by their ability to manipulate public sentiments and emotions to gain support and influence, rather than relying on logical reasoning or factual evidence. This approach often involves stirring up feelings such as anger, fear, or pride, which can mobilize a crowd and create a strong emotional connection with constituents. Demagogues may employ rhetoric that resonates with the fears and desires of the populace, appealing directly to their emotions rather than engaging in rational discourse.

In contrast, the other options highlight qualities that are generally not associated with demagogues. Reliance on academic backgrounds and education suggests a fact-based approach, which demagogues typically avoid. Similarly, focusing on factual and scientific data in arguments is opposite to the demagogic style, as it prioritizes logical reasoning over emotional appeal. Advocacy for non-violence and peace does not align with the aggressive and often incendiary tactics used by demagogues, who may incite conflict to achieve their goals. Thus, the correct choice accurately reflects the essence of demagoguery in politics.
