In mathematics, an unsubstantiated armchair opinion is called a "conjecture", and can be subsequently proven or disproven by the same person or another person.

If scientists of yore had "remain silent until you find a reason for your opinion" we'd probably still think the sun revolves around the earth.

Mathematicians clearly label their conjectures, but this was phrased as a statement. Surely you are not suggesting that mathematicians go around publishing their guesses with language indistinguishable from their knowledge.

Strictly speaking, as you suggest, it wouldn't be wrong to write, "I thought about it, and although I don't have any reason to believe it, the notion that women don't form groups for the sake of comradeship settled in to my mind, and with a gust of wind, floated from there to this paper." However nobody would ever write that! Passing off guesses as knowledge only works as a career if you try to dress up your guesses as knowledge, for example by phrasing them in a way that makes it sound like they're already commonly known.

What he wrote was essentially common knowledge at the time, not a novel theory that needed defending. That’s why elsewhere in this thread it is pointed out that you can’t judge it by today’s standards. We have different common knowledge today that people use as justifications for their opinions without feeling any need to cite a paper. Some of that knowledge is right and some wrong.

For a modern example, you could take a look at a comment that says his conclusions were wrong without citing any evidence.

From a social standpoint, uncritically repeating what everybody thinks is acceptable. From a scientific standpoint, it is not.

You seem to be making a lot of arguments about science and how things have to happen without citing any papers or evidence.
