The Wikipedia the article you quoted goes on to say:
This has recently been interpreted by a few writers as a sarcastic remark directed against Hooke. This is speculative; Hooke and Newton had exchanged many letters in tones of mutual regard, and Hooke was not of particularly short stature, although he was of slight build and had been afflicted from his youth with a severe kyphosis. However, at some point, when Robert Hooke criticized some of Newton's ideas regarding optics, Newton was so offended that he withdrew from public debate. The two men remained enemies until Hooke's death.
I linked to Google Books' sample of pages 187-188 of Michael White's book Isaac Newton: The Last Sorcerer. The author looks at their correspondence in some detail, and makes an emphatic conclusion which I won't spoil here.
So is his conclusion "speculative"? I don't know. But he certainly wasn't unaware of the context of the quote.
I remain of course, your most humble servant.
Recently I've been considering declaring Crocker's Rules. The wiki page and source document don't suggest any particular time limit or training period, and also don't provide any empirical results of testing it, positive or negative. It sounds good in theory, but how does it affect people in the real world?
It seems like an "obviously cool" idea but the risk to one's reputation is worth taking into consideration. If it is clear that the risk is low, and if the value to be gained is clearly very high, we should probably be doing more to encourage it as an explicit norm.
On the other hand, if it is just one of those ideas that sounds better in theory than it is in practice (because the theory does not correctly model reality), or is just yet another signaling game with a net negative value, that is worth knowing as well.
I haven't seen anyone argue against Crocker's Rules or claim it ruined their life, so my estimation is that the risk is low (although there is a small sample size to start with). Also, I have seen at least one statement from lukeprog implying that it has been instrumental in triggering updates during live conversations he has observed, indicating that the value is high (though its causal role is not firmly established in that example).
Does anyone have further data points to add?
