Answer:
groupthink
Step-by-step explanation:
Based on the information provided within the question it can be said that Henry, Bekah, and Marcella are engaged in groupthink. In the sociological perspective, this term refers to when individuals in a group tend to agree with each other in order to preserve the harmony/peace within the group. This leads to bad decision making and unprecedented outcomes. Which is what is happening in this scenario since Bekah and Marcella agree with Henry without doing any research on the decision that they were making.
