Josue wants to know which bathroom stall people are most likely to use. He asks his school’s IRB if he can set up a camera in the bathroom to secretly record the users’ behaviors. Why should the IRB deny Josue’s request?

Josues is violating the participants' privacy.

Explanation:

In scientific research, several requirements must be considered to protect the rights of the participants, which is why there is an institution in charge of examining and approving these requirements when presenting a study by an investigator.

This institution is called the Institutional Review Board (IRB), it is an association of doctors, scientists and other professions that aim to analyze, approve and monitor research involving people. The IRB protects the welfare and rights of the participants. They make sure that investigations do not violate people's privacy and cause them any harm.

For example in the case of Josue's study, it would not be accepted by the Institutional Review Board (IRB), because it violates the privacy of people, and this could cause other damages, this reason will cause the IRB to deny Josue to continue with your investigation.

I hope this information can help you.
