A comparison table can make a decision easier to examine when several options have different strengths. It helps expose the criteria you are using rather than allowing one attractive feature to dominate unnoticed. List the options and a small set of relevant criteria. Separate essential requirements from preferences. Record evidence and uncertainty for each option. If you use scores, remember that the numbers reflect judgement and should not create false precision. For choosing a study location, criteria might include noise, travel time, opening hours, and available space. An option that fails an essential requirement should not win merely because it scores well on minor preferences. Consider whether a reversible trial could resolve uncertainty. Practice: Compare three options for a low-stakes decision. Identify the most important criterion and one piece of missing information that could change your choice.
