EXPERIMENT AND THEORY
When we carry out an experiment, we do it because we don't know what the
result will be. If we knew in advance we wouldn't bother. There must be two, or
several, or a large number of possibilities. We may expect one of several outcomes,
or we may not know at all what to expect.
For the experiment, whatever its purpose, to be considered a test of some theory,
the outcome must make a difference. If the experiment has one result, we must be led
to a greater degree of confidence in our theory, if it has another result we must be led
to a greater degree of doubt. If the degree of our belief was unaffected by the result
