Although I concluded that the psychological concept emphasizes privacy as
control over or regulation of or, more narrowly, limitations on or exemption from
scrutiny, surveillance, or unwanted access (Margulis 1977), there have been (e.g.,
Pennock and Chapman 1971) and continue to be legal and philosophical analyses of
the meaning of privacy, some of which, as noted (e.g., Tavani 2007), would have us
go beyond the limited-access perspective (Allen 1988) or raise questions about the
boundaries of privacy (e.g., Davis 2009). In the final analysis, privacy remains an
elastic concept. Therefore, if you intend to use a behavioral theory of privacy, you
should determine whether its definition of privacy meets your requirements.
