Ethics of social psychology

The goal of social psychology is to understand cognition and
behaviour as they naturally occur in a social context, but the
very act of observing people can influence and alter their
behaviour. For this reason, many social psychology experiments
utilize deception to conceal or distort certain aspects of the
study. Deception may include false cover stories, false
participants (known as confederates or stooges), false feedback
given to the participants, and so on.

I wonder how many can see themselves and they part they play
in this exercise, this egotistical pursuit in the name of study.
Judgement based solely on observation, presuming to know just
by watching.

Observation within a limited sphere, with no
thought on what goes on beyond that situation, with no thought
for history. Just occupied on the surface.
