Truth in science is always determined from observational facts.

Indeed, scientific truth by consensus has had a uniformly bad history.

If the facts are contrary to any predictions, then the hypothesis is wrong no matter how appealing.

One finds the truth by making a hypothesis and comparing observations with the hypothesis.

The more facts one introduces, the more truth one shows, the more determined the bigot is to cling to his belief.

For every fact there is an infinity of hypotheses.
