Final answer:
The absence of interest groups representing a group of people with shared policy goals can occur due to free riders, disagreements over the details of goals, and individuals' reluctance to join certain groups.
Step-by-step explanation:
In situations where there is a group of people who share policy goals but no interest group representing them, it is often because of various reasons.
- One reason is the presence of free riders who benefit from the collective goods provided by an interest group without actively participating or contributing to the group's efforts.
- Another reason is the disagreement among members over the specific details of the shared goals. For example, in the context of climate change policy, members may have different opinions on whether to ban gas-powered cars or provide incentives for electric cars.
- Additionally, some individuals may not realize or accept that they have shared interests with others, while others may be unwilling to join a group representing controversial or unpopular views.
