> What does the interview process look like for a craftsperson?
Welcome to my shop. Here's some wood. Make a chair!
In most of the interviews I conduct, I get the candidate to write follow a spec we've written and some code. And I get the candidate to debug a program with some failing unit tests. About half of the candidates I interview fresh out of school have no idea how to get started debugging a program they didn't write. You need to do that just about every day at work, and its usually not even mentioned at school.
But I've worked as a teacher too. I will move heaven and earth for my students, but in my darkest moments I think taboo thoughts. Maybe IQ is a real thing, and maybe some people just don't have the neural hardware to ever be good at programming. If thats true, we do those people a huge disservice. We steal years of their lives and tens to hundreds of thousands of dollars training them in a skill they can never master. I'd love to see the stats on how many people graduate from a CS program, try but never find reliable work in our industry. I worry the numbers might be damning.
A few months ago a candidate I interviewed asked for feedback at the end of the interview. He wanted to know I recommended that he practice so he could improve. I said he should pick an opensource project on github - preferably something thats not too big and look through the issue tracker. Pick a simple looking bug and try and fix the bug and submit a PR. His whole manner changed after I said that - the idea of doing that was so incredibly daunting to him. But that right there? More or less, thats the hiring bar. As an interviewer I'm trying to answer the question "If I hire you, can you do the work?". Read, think, understand, modify, write code, communicate it to your team. Thats the work and thats the bar.
We maintain a queue of beginner-friendly tasks, and someone familiar with the codebase sits down with the new hire to orient them to what's needed, why, and the relevant files/modules to make the change. Then they're available for questions and patient with a laborious code review. You do 3 or 4 of these before you're expected to be independently productive.
Approaching an open source project cold is a bit higher than the bar.
Both of your "taboo thoughts" seem blatantly obvious to me, and not especially taboo. Intelligence obviously exists and some people have more of it than others, even if the metric "IQ" doesn't perfectly capture it. And yeah, some people are not cut out to be programmers. Why are we pretending otherwise?
I find that there's a borderline self-contradictory aspect of hacker culture. While we romanticize the concept of the 10x programmer, which is an individual of genius, our culture also stresses the concept of autodidacticism. Teach yourself to code. Just use MOOCs. Build it yourself. Hack on an open source project. So there's this tension between valorizing the inborn superhuman and the belief that it's possible to reach greatness- though perhaps not 10x greatness- by pulling yourself up by your bootstraps.
In a way, this is mirrored by the organizations themselves. Startups who make the right moves, and work hard through grit and 60-hour weeks, can become unicorns. Also some startups are led by visionary founders and cannot fail.
So all of this, buttressed by real world labor demands, create incentives for people to try to become programmers. Even those who aren't "cut out to be programmers." Our increasingly cutthroat and unequal society also incentivizes people shifting to programming as a safe career choice. "Learn to code."
I don't know how we can stop "pretending otherwise." Tech companies continue to complain about the engineering talent shortage. Bootcamps and online courses continue to promise people that they can become that talent. There aren't any agreed-upon industry standards by which to exclude people who truly aren't fit for it. FAAMG has infinite money and power in the industry to continue their entrenched practices. Most startups cargo cult the leading megacorps' processes. So instead, candidates are encouraged to continue grinding Leetcode and apply, apply again.

Those seem like orthogonal aspects. If we stressed the idea that you had to do (say) a 4-year degree at a great university, or something akin to the bar exam, would that be any more compatible with the idea that some people are 10x better than others? If anything I'd say the opposite: we'd expect most of the Harvard graduating class to be on roughly the same level, it seems a lot less wild that some self-taught people could be 10x better than others.

This happens in every field though? You get people who are desperate to become a doctor and apply to med school year after year, despite being completely unsuited to it. You get people who insist they're gonna make it as an actor/musician/comedian and spend decades working crappy day jobs so they can live where the action is, when really they'd be better advised to pick a career they're good at.

Well, if we told people outright that programming is a matter of IQ, and gave an actual IQ test rather than an IQ-like test in interviews, that might help some people realise it's not for them. You're right that what catches on in the industry is largely a function of what the most successful companies pick, but ultimately that list of top companies is not static and we'd hope that companies with better hiring practices will (eventually) rise to the top.

That's not the point I was trying to make- I'm saying that in programming we both prize talent born of nature, and skill honed by nurture. (Though admittedly that may exist in many other disciplines.) Because of the latter emphasis on grit, hacker culture encourages self-improvement and going beyond the capacities one started with. That dogma of self-improvement goes against the notion that people are not cut out to be programmers.
Though of course, this could also be a marketing ploy for recruitment on behalf of management: "Anyone can code, you should learn to. But we only hire from the best." By encouraging an increase in talent, they have a larger labor pool to choose from (and potentially undercut wages), while plucking out the few that can pass their interviews.
> This happens in every field though?
To some degree, but the details vary. Medicine or law used to be seen as safe secure careers into the (upper) middle class, but doctors are limited through the AMA, and currently law is a notoriously difficult and costly profession with dwindling prospects. Entertainment and the arts is universally known as a risky proposition. We're talking about software, which has had the reputation of being the current surefire path to a stable, even successful, career, for at least the past two or three decades.

Leaving aside the legality of using IQ tests to exclude candidates, that opens up the questions of if there is a direct correlation between programming good software and IQ, why programming out of all STEM fields should focus so heavily on IQ, and why all of those other technical and engineering professions don't need to resort to IQ tests for hiring.
