What is a caveat about the Investment Model's scope?

• A. It was developed and validated primarily on people in monogamous romantic relationships.
• B. It only applies to platonic friendships.
• C. It ignores satisfaction and investments.
• D. It was tested exclusively in non-romantic contexts.

Answer: (A)

The main idea tested is how far the Investment Model’s findings can be applied beyond the situations it was studied in. The strongest caveat is that this model was developed and validated mainly with people in monogamous romantic relationships. That means its predictions about commitment and staying together are most reliable for monogamous, often long-term couples, typically in Western contexts. Because the original research focused on those kinds of relationships, applying the model to casual dating, non-monogamous setups, same-sex relationships, or friendships stretches beyond the data that backed it. The other statements don’t fit as well: the model explicitly incorporates satisfaction, investments, and alternatives as key factors; it is not limited to platonic friendships, and it isn’t tested only in non-romantic contexts.
