A key factor to decision making under uncertainty includes these sources:

• A. Random guess driven by personal bias
• B. Public opinion and rumors
• C. Previous experience; knowledge of how the enemy operated and whatever intelligence is available; likely outcomes
• D. Thorough data and perfect certainty

Answer: (C)

When making decisions under uncertainty, base actions on what you know from experience and on the best information available about how things could unfold. Past experience provides patterns: what has happened in similar situations, what strategies worked, and what outcomes tended to follow certain actions. Coupled with any intelligence or knowledge about how competing factors or challenges might behave, this helps you anticipate likely scenarios and weigh options more effectively. Relying on random guessing or personal biases, or on public opinion and rumors, introduces misinformation and increases risk. Even with thorough data, you can’t achieve perfect certainty in uncertain situations, so use the best available information and experience to estimate outcomes and choose the most prudent course.
