Final answer:
Predicting what friends will think is not part of standard decision-making processes, which involve critical thinking and considering opportunity costs of different choices.
Step-by-step explanation:
Thinking about and listing one's options in the process of decision making includes various steps such as identifying possible alternative outcomes, determining what is most important, and thinking about what choices could be made. However, it does not typically include predicting what friends will think. The answer to the question is that predicting what friends will think is the option that is not part of the decision-making process.
Critical thinking is crucial in this process as it involves analyzing different perspectives and arguments to reach an informed conclusion. The opportunity cost is also an important concept to consider, as it informs the value of the best alternative foregone in the decision-making process.
