Why do experiments?
Compare experiments on identical twins:
- What is your experiment for?
- I want to find out if twins reared apart to those reared together and nonidentical twins too.
- Why?
- We can get estimates of the genetic and social contributors to performance
- Why?
- Because the role of genetics in behavior is one of the great unsolved questions.
Experiments should address research questions
- otherwise they can just be “track meets”
