Replacing Bohr's model with Schrodinger's equation is one example. Or Newtonian physics with relativistic physics. These were proven to be better models, of course, but if great physicists applied Occam's razor to everything like some on HN, Einstein/Schrodinger would have never bothered investigating further.

Perhaps the Catholic church invoked Occam's razor when Galileo suggested the orbits of celestial bodies are more complex. Occam's razor is a good way of advocating that the existence of one single god is the default answer we should all accept, because you and I have no evidence for or against anything else and any other explanation for existential questions is going to be more complex.

The point is that bringing up Occam's Razor on every thread adds no value, does not need to be verbalized on a forum of smart people like HN, and frankly seems to be a way to justify intellectual laziness/closed-mindedness (which might be useful in high stakes/low time situations, but not in an 'intellectual' internet forum where people have plenty of free time to make better arguments).

Newtonian physics is the easiest example to criticize, because it’s precisely what I said: special relativity was a new model to fix blatant flaws with the previous model. Occam’s razor only concerns comparing two theories which account for the same phenomena. Special relativity was a new model that accounted for more phenomena, so it’s really not surprising (and certainly not a violation of Occam’s razor) if it was less simple.
