An Institutional Review Board (IRB) or Independent Ethics Committee (IEC) ideally should consist of at least five members. This number is significant because it ensures that the board is adequately diverse in terms of expertise, perspective, and opinion, which contributes to a thorough evaluation of research protocols involving human subjects.

A minimum of five members helps in achieving a balanced and fair assessment of the ethical implications and risks of proposed research. It allows for a variety of viewpoints, including those from different disciplines, backgrounds, and gender, which is crucial when considering the welfare of participants. This diversity aids in minimizing biases that could arise with a smaller group, promoting a more comprehensive review process.

Moreover, having at least five members helps in meeting regulatory requirements, as many guidelines specify this number to enhance the quality of oversight and decision-making. The presence of multiple perspectives ensures that the board can effectively discuss and deliberate on complex ethical issues, which is essential for protecting the rights and welfare of research participants.
