The Hawthorne Effect in Election Studies: The Impact of Survey Participation on Voting

Movements of the heavenly bodies are not affected in any discernible way by the fact that there are people on earth recording the apparent movement. Similarly it is almost inconceivable that the planets would alter their orbits because of Kepler's discovery and publication of the laws of planetary motion. The social and behavioural sciences are different in that the objects under investigation may behave differently as a result of the research process. This is particularly true when the method involves naturalistic observation, surveys or experiments. When people behave differently because of being research subjects, this is called a Hawthorne effect.
