Why 'Do You Have Any Questions?' Is Not Enough — Informed Consent in Practice

Why 'Do You Have Any Questions?' Is Not Enough

Establishes why passive comprehension checks fail, presents research on the comprehension gap, and makes the case for proactive comprehension assessment as an ethical obligation.

20 min

The most dangerous false positive in clinical research

The consent conversation is over. It lasted 40 minutes. The coordinator covered every section of the document -- purpose, procedures, risks, benefits, alternatives, voluntariness, confidentiality. The participant listened. Nodded at appropriate moments. Made eye contact. When the coordinator reached the end, she asked the question that closes virtually every consent encounter in clinical research: "Do you have any questions?"

The participant said no.

The form was signed. The participant left. And somewhere in the walk back to the parking garage, the participant turned to a family member and said: "I am not really sure what I just agreed to, but the coordinator seemed to think it was straightforward."

This is not an unusual outcome. It is the usual outcome. And it represents, in my view, the single most dangerous false positive in our field -- the moment when a coordinator concludes that comprehension has been achieved because the participant said "no" to a question that was never designed to detect comprehension in the first place.

This lesson is about that gap. Not about how to close it -- we will get to that in the lessons that follow. But about understanding, with clarity and evidence, why it exists. Because if you do not appreciate the size and nature of this problem, you will not be motivated to adopt the solutions.

What you will learn4 objectives

By the end of this lesson, you will be able to:

Identify the psychological barriers that prevent participants from asking questions or admitting confusion, including social desirability bias, authority deference, and health literacy shame
Cite the research evidence demonstrating that participants routinely consent without adequate comprehension despite reporting that they understand
Distinguish between verification of comprehension (confirming actual understanding) and verification of assent (confirming willingness to proceed), explaining why both are necessary
Explain the CRC's ethical obligation to proactively assess comprehension rather than relying on participant self-report
