In the cognitive triangle, which process helps to maintain or reinforce the initial belief when outcomes align with it?

• A. Events changing thoughts directly.
• B. External feedback alone shapes thinking.
• C. Behaviors reinforcing thoughts.
• D. Feelings erode beliefs.

Answer: (C)

In the cognitive triangle, thoughts, feelings, and behaviors form a feedback loop. When outcomes align with an initial belief, engaging in the behavior that expresses that belief provides concrete evidence that the belief is true, reinforcing it. This is how a self-fulfilling pattern develops: the action yields results that are interpreted as confirmation, making the belief more resistant to change. For example, if someone believes they’re unworthy of friendship, they may withdraw socially; the lack of interaction or neutral responses then reinforces the belief by seeming to validate it, so the pattern persists. The other options miss this loop: changing thoughts directly bypasses behavior-based evidence; external feedback alone doesn’t account for how actions reinforce beliefs; and feelings eroding beliefs would counteract the reinforcement process.
