My Dad was an academic and that sounds more like his life than how @MrsNorthie described it.This isn't my experience. Questions are the daily bread and butter of an academic. Getting published in a refereed journal requires one to write something that passes the scrutiny first of the editor, then, if it passes that hurdle, of however many referees s/he sends it to for comment (and those referees are other academics, some of whom will ask very difficult questions about it just to show how much they know and how clever they are ), then back to the editor with the referees' comments, for a final decision after however many revisions have been made, and then it goes through a copy editor who picks up any remaining flaws, faux pas and stylistic infelicities. The best journals have very skilled people doing each and every job on this journey that a paper published in it has to take. Journals are ranked by how hard (or not) it is to get published in them, since there is this quality control (unlike the internet, where any old rubbish can get published - without the platforms actually admitting it is publishing such nonsense to the world).
And getting to be an academic is such a long, hard and expensive journey, nobody gets into it without a passion for their work. That passion may be killed by the journey, or the people met on the journey of course. Few make it to a permanent post, which is rarely achieved before they get to 30.
After he died I went through endless correspondence much of which was questions about his papers or him questioning other people’s work.
To me a non-academic it all seemed quite adversarial and nit-picking, but here I am now relying on academic work to have really solid foundations in order to trust the findings for decision making.
Maybe it depends on the field.
Here are some chickens sheltering from the downpour (as was I).
