One of the key tenets of the scientific method is that the experiments we design must
be reproducible, so that others can convince themselves of the validity of the hypothesis.
Hypotheses must also be falsifiable, so that we can know for sure when a given hypoth-
esis is wrong (and thus needs revision). As Einstein famously is reported to have said
(“No amount of experimentation can ever prove me right; a single experiment can prove
me wrong”), we can never know for sure that any hypothesis is absolutely correct; we
can only validate that it is consistent with our observations.
