What happens if new research is found to conflict with existing scientific theory?
What happens if new research is found to conflict with existing scientific theory? The theory is changed to fit with the new
information.

What is the purpose of a control group in an experiment? Group that serves as a standard of
comparison with another group - both groups are the exact same except for one factor.
