This is a prudent policy. Much harm has been done to unwitting research subjects. The danger may be Less in the social, sciences, but here, too, scholars must be honest with their subjects. And while there may be little privacy to violate in an elevator, given the frequent use of surveillance cameras, that does not eliminate this duty.

Conley says consent is not required when it is impossible to obtain and the expectation of privacy is low (filming a crowd at a baseball game, for example), or when the research is sufficiently important (studying prisoner-guard interactions, say] and deception is necessary to...
