Explanation

A real advantage of online surveys is that participants may quit whenever they feel uncomfortable.

This freedom to withdraw strengthens respect for participant autonomy.

Debriefing and clarification remain necessary, not reduced, in web research.

Online formats do not improve participants' grasp of informed consent.

Easy withdrawal supports the ethical principle of voluntary participation.
