Final answer:
A leader who appeals to emotions rather than rational arguments is known as a charismatic leader, which can inspire fervent support during crises and form personality cults around their perceived special qualities. Andrew Jackson and Adolf Hitler are historical examples of such leaders.
Step-by-step explanation:
A leader who doesn't focus on making a good argument or having good ideas, but rather uses their ability to get a crowd emotionally charged is often referred to as a charismatic leader. Charismatic leaders rely on their personal appeal and ability to connect with people's feelings—such as fear, sympathy, or anger—to inspire and mobilize them. This form of leadership becomes particularly prominent in times of crisis, where leaders like Andrew Jackson or during more darker periods someone such as Adolf Hitler, have risen to power by offering radical solutions and new visions for the world order. These leaders often form a personality cult, gaining devotion from their followers based on perceived extraordinary qualities.
This type of appeal to emotions rather than rational arguments can be seen in various areas, including political campaigns and national emergencies, where presidents may use inspiring speeches to comfort and unite the population. The 'rally 'round the flag' phenomenon is an example of how a leader's charisma and ability to appeal to emotions can lead to increased approval ratings. Regardless of the evidence, populist politicians are known to manipulate the emotions of the populace to influence their opinions and actions for personal or political gain.
