Final answer:
The scenarios can be matched with different social influence terms including bystander helplessness, group polarization, and deindividuation.
Step-by-step explanation:
One of the scenarios described in the question is an example of bystander helplessness. In this scenario, Samuel notices a man collapsed next to a bench, but he is not concerned because other people in the park continue with their business. This demonstrates the bystander effect, where people are less likely to help during an emergency when there are other bystanders present. This is often due to diffusion of responsibility, where individuals feel less responsible because others are present.
Another scenario relates to group polarization. At the dinner table, once everyone realizes they belong to the same political party, they feel free to joke and insult the other party. This is an example of group polarization, where group members strengthen their original attitudes after discussing them within the group. In this case, the group members become more extreme in their opinions about the other political party.
The third scenario is an example of deindividuation. The state-controlled media encourages worship of the dictator by publishing lofty stories about his achievements. This type of social influence can lead to deindividuation, where individuals feel a sense of anonymity and reduced accountability when in a group. In this case, the state-controlled media encourages conformity and discourages individual thought.
