One of the proof of a good scientific experiment is the ability to reproduce the steps leading to the results obtained from the experiment.
To proof the validity of the claims of an experiment by other scientists:
- Every experiment must be reproduceable by other scientists.
- This will enable the experiment to be rid of any bias.
- For the conclusions of an experiment to be validated by other scientists, such experiment should be tested by others.
- If the results are the same, then the hypothesis can be advanced.
- If not, the experiment is redesigned or discarded.
