Which type of consent requires no action from the individual to be assumed as given?

The type of consent that requires no action from the individual to be assumed as given is known as implied consent. This means that consent is inferred from the actions, facts, or circumstances of a particular situation rather than being explicitly stated.

For instance, if a patient goes to a doctor and opens their mouth for an oral examination, this behavior signifies that they have given implied consent for the examination to take place, even though they may not have verbally agreed to it. Implied consent is often used in situations where it is reasonable to assume that the person would consent based on their expressions or behaviors.

In contrast, express consent implies that an individual has explicitly agreed to a process or treatment, typically through verbal or written confirmation. Informed consent involves providing a person with information about the risks and benefits of a procedure, allowing them to make an educated decision. Opt-out consent refers to a scenario where individuals are presumed to have consented unless they take specific action to decline participation. These other types of consent necessitate a more active form of agreement than implied consent does.
