Interesting extracts from my readings for Bioethics and Responsible principles for Engineers module:

"Biophysical characteristics are sometimes associated with
a consumer’s ability to recognize and protect one’s self from
persuasion attempts (Laczniak, Muehling, and Carlson 1995)
and the ability to understand the implications of marketing
messages (Laczniak and Murphy 1993; Rittenburg and
Parasarathy 1997). Sometimes these biophysical characteristics
are used to advance the “dumb consumer model” (Calfee
and Ringold 1992), which posits sellers can deceive consumers
and consumers are helpless to resist. At other times, populations
with these biophysical characteristics are used to
advance the notion of a “smart consumer model” (Calfee and
Ringold 1992), where the consumers recognize that sellers
are trying to stimulate a purchase and they are active agents in
their own consumption decisions. Calfee and Ringold (1992)
believe in the “smart consumer model” more than its alternative,
but the alternative does allow for the possibility that
there may be times when consumers truly are unable to be
“smart.”

Beware of what advertisements could do to you!
