Step 3d:
How to Cancel an Experiment

The cancellation deadline is 24 hours before the start of the experiment. For example, you should cancel out before Thursday at 1:00pm if your experiment is on Friday at 1:00pm.

Why should I cancel?

  • Accruing 3 no-shows automatically disables you from signing up! By canceling, you will not receive a no-show.
    • Arriving after the experiment start time may also result in a no-show
  • Consider others - Canceling out in a timely manner opens up a spot for another participant and helps the researchers run a successful experiment.
  • Learn how to be a responsible adult. Most offices (dentists and doctors) have a 24 hour cancellation policy.
