Final answer:
The statement that more intelligent people generally make better decisions than less intelligent people is false. Intelligence is just one of many factors that contribute to decision-making, including access to data, experience, and social factors.
Step-by-step explanation:
The belief that more intelligent people generally make better decisions than less intelligent people is false. Intelligence can influence decision-making, but it's not the sole factor. Better decision-making often involves a mix of factors including access to relevant data, experience, critical thinking, emotional intelligence, and more. In the context of political science and social studies, political scientists are more likely to make accurate predictions when they have lots of data (choice b) and when the group has expertise (choice d) or when the answer is unclear (choice b) as in the conditions under informational social influence. This shows that decision-making and predictions are multifaceted and not just a result of high intelligence alone. Moreover, factors such as environment, socialization, and community interests play significant roles in decision-making which adds to the complexity of the process beyond sheer intelligence (choices c and d from question 24 and 7, respectively). Additionally, majority rule can indeed fail to produce a single preferred outcome when there are more than two choices (statement 5), further illustrating the complications in decision-making.
