How does the Investment Model explain commitment in casual relationships?

• A. It cannot apply; only serious relationships matter.
• B. It can apply to casual relationships, such as friends with benefits, by assessing satisfaction, alternatives, and investments.
• C. It only applies to long-term marriages.
• D. It ignores investments in casual contexts.

Answer: (B)

The key idea is that commitment comes from a simple calculation: how satisfied you are with the current arrangement, how attractive the alternatives are, and how much you’ve already invested in it. The Investment Model isn’t limited to serious, long-term unions; it can apply to casual relationships too, because people still weigh rewards and costs, compare options, and consider what would be lost if they ended things. Satisfaction in a casual setup comes from the balance of rewards (fun, connection, sexual satisfaction) and costs (time, effort, potential drama). If the rewards feel high and the costs manageable, you’re more satisfied and inclined to stay. Alternatives matter too; if someone perceives appealing options—better matches, less commitment elsewhere—that perception can pull them away from the casual arrangement. Investments—time spent, emotional energy, shared routines, secrecy, or future expectations—make ending the casual relationship more costly, so higher investments tend to bolster commitment even when the relationship is casual. So the model explains why people stay in or end casual arrangements based on these three factors, not just on whether a relationship is labeled as serious. Choices that say the model doesn’t apply to casual contexts or ignores investments don’t fit the framework.
