Final answer:
The phrase mentioned is an example of counterfactual thinking, where one imagines different outcomes based on different actions or decisions.
Step-by-step explanation:
The statement, "If I had only used my 5-iron, I would have put the ball close to the hole," after hitting a ball into a pond is an example of counterfactual thinking. This type of thinking involves imagining alternative scenarios and outcomes that didn't happen but could have occurred if different decisions or actions had been taken. It is not an example of the self-serving bias, which involves making internal attributions for successes and external attributions for failures. Nor is it an example of the availability heuristic, which would be making a decision based on readily accessible examples rather than basing decisions on all information.
