From the article: The common view is that as we eliminate falsity, what we have left is closer to the truth.  In other words, along with the current theory, we have a list of theories or hypotheses which have been discarded, never to be entertained again.

This is not always the case, though. Consider the gravitational constant. Einstein once called it his "greatest mistake," discarding it. However, now there are new studies coming out in which people are finding it a useful postulate.

That follows without a gap:
>>It is as much of a mistake to think that these "refuted" hypotheses are "false" as it is to think that the "accepted" theory is "true". Popper himself was aware of this.<<
