The following suggestions will help you avoid common pitfalls in the risks and benefits section. Avoid underestimating risks: a rule of thumb to follow is "if the experiment exposes the subject to risks greater than what might be expected during the course of a normal day, state it." Do not state that risks are "unknown" because this is interpreted as "none." State that "the risks are not knownat this time" or use another qualifier. Avoid overestimated benefits and lofty statements, such as "the betterment of humanity, advancement of science or knowledge."
