  • giving full info may alter the way they behave this is called deception
  • not knowing aims may upset some participants
  • some experiementers need to deliberately decieve participants

to minimise harm:

  • avoide using deception unless necessary
  • avoide other problems such as embarasment
  • explain real purpose asap
  • allow to withdraw

experiments shoiuld try to represent real life as much as possible.
