Which principle is essential for ethical Silent Library task design?

• A. Coercion.
• B. Deception without disclosure.
• C. Informed consent.
• D. Ignoring participant welfare.

Answer: (C)

Informed consent is the essential principle because it centers on respect for a person’s autonomy and safety. When participants understand exactly what the Silent Library task will involve—the potential surprises, any risks or discomfort, what data or observations will be collected, and how confidentiality will be handled—and they agree to participate freely, they can make a real, voluntary decision about taking part. This also implies they know they can withdraw at any time without penalty, which protects their right to control their own involvement.

This approach matters because it builds trust between organizers and participants and establishes a baseline of safety. Even if the activity seems light, people should never be put in a situation where they feel pressured or misled about what they’re agreeing to.

Coercion, on the other hand, removes voluntary participation by pressuring someone to take part. Deception without disclosure breaches trust and can cause distress if participants later feel misled about what happened. Ignoring participant welfare fails the fundamental duty to protect people from harm. In all these respects, informed consent best aligns with ethical practice and the goal of running a responsible Silent Library task.
