Then the participant's wife, who has been sitting quietly in the corner, speaks up: "What if the drug makes his kidneys worse? He already has stage 3 kidney disease. His nephrologist has not said anything about this study."

The coordinator pauses. The question is medically specific -- it will need the investigator's input. But the participant is watching, and his wife's eyes have filled with tears. She is not asking for a pharmacokinetic analysis. She is asking whether her husband is safe. And the coordinator realizes, in that moment, that they do not have a prepared way to handle this -- not the clinical escalation, which they know how to manage, but the emotional weight of the question itself.

This is the lesson about the work that happens before that moment.

The participant will have questions. That much is certain. In over three decades of watching consent conversations, I have never once seen a prospective participant sit through a discussion of study procedures, risks, benefits, randomization, and data collection without asking something. The questions vary in specificity, in emotional intensity, and in whether they fall within the coordinator's scope of practice. But they come. Always.

And the worst time to figure out your answer is while the participant is sitting across from you.
