When a scientist serves in an advisory role to society, he or she must

be careful to present only objective facts

Explanation:

Human beings have a natural tendency towards bias. It us often difficult to guarantee absolute objectivity even in scientific parlance because of the natural tendency of individuals towards bias.

Hence, when a scientist is invited to serve in an advisory role in society, it is necessary for him or her to ensure absolute objectivity at all times. Only reliable and verifiable facts should be the basis for decision making and he or she must never lean on any kind of subjective bias.
