ABSTRACT
Much psychological research involves people. This makes the conduct of research much
more complex than work in the natural sciences. If you mix copper sulphate and
sulphuric acid the molecules do not sit in the test-tube wondering why you have done this
and what you are hoping to prove. If you deprive a plant of light it doesn’t think:
‘A-ha!…photosynthesis experiment. What shall I do this time?’ People are
reflexive-they consider what you are doing and why.
