Some scientists have expressed reservations about quantum theory because of its counterintuitive consequences. But despite rigorous attempts to show that quantum theory' s predictions were inaccurate, they were shown to be accurate within the generally accepted statistical margin of error. These results, which have not been equaled by quantum theory' s competitors, warrant acceptance of quantum theory.
The principle 'A scientific theory should be accepted if it has been subjected to serious attempts to disprove it and has withstood all of them' most helps to justify the reasoning above.
