It says something new and specific about paradigm shifts in particular (not just about model-building as a scientific habit of thought)?
In terms of the spectrum of cognitive change, I think her references do recategorize what is commonly called "paradigm shifts" by placing them at one end of a spectrum of cognitive change in a manner that is new and specific, yes.
Whether this is "about" paradigm shift specifically seems less certain, and I think both yes/no positions defensible.
If so, are you quoting that as a claim of Nersessian's, made more or less explicit in "Creating Scientific Concepts", or is that your synthesis of what you read?
I'm uncertain what referent is meant by "that".
Nobody believes this claim of yours...
Within an infinitesimally small corner of the internet chosen for it's potential for hostility? That's partially correct.
Many claims did receive support which seemed as irrational and poorly-informed as most of the criticism. The support seemed about average for criticism in this venue regarding interest in accuracy for my position. This level of interest is far below any with which I've previously interacted. One of the Starship Vlog episodes has the head of NASA education asking me to put the presentation online for later reference. Being invited to present and JSC and in Huntsville, you'll understand my taking your assertion with a grain of salt.
...you've provided no convincing arguments that the claim is correct,
You yourself simultaneously seem to claim that my position is unexplained and without merit - an obvious fallacy.
This is like skeptics who claim pseudo-scientists' propositions are both unfalsifiable and proven to be wrong - when they clearly can't be both.
My available evidence (starting with the thread title) is that participants in this group are interested in coming up with narratives in which others are inferior "crackpots"...thus their crackpot ideas. There is an obvious psychological payoff of being "in the know" and having "special knowledge" common to any conspiracy theorist community.
Investing time in understanding claims runs at cross purpose to such priorities, so I disagree with your presumption that in this venue "convincing" is a reasonable expectation. I wouldn't go to a 9/11 conspiracy thread and try to convince members of improvements to structural engineering for example.
If we can summarize what we think someone claims, in a manner they agree communicates their intent, then I think our criticism has some minimal level of credibility.
Want me to take criticism seriously? Either get lucky (which has happened here) or state a position I endorse as accurate and criticize that.
...scraps of concrete proposals that were flatly counterproductive...
I'm having a house built right now. Workers taking time to do taxes is flatly counterproductive and costly to me, but I don't have a choice between production with admin overhead and production without it. Production without administrative overhead simply can't get done. The choice is between progress incurring "counterproductive" overhead vs. no progress. For the house to get built, loads of time, money, and effort go into other things. That's life in the real world where we have to accomplish stuff.
At the Sloan school, they call this overhead "facilitating processes", and every MBA has to demonstrate familiarity with them prior to graduating.
Physics research is not only disembodied minds working to tease out the mysteries of the universe, (which it includes) it's also facilities, budgets, schedules, office politics, taxes, personalities, and dealing with management and administrative facilitating processes to keep the science going.
We would have to be extremely provincial and naive not to see that facilitating processes are needed, and I tend to doubt this is not understood on some level. Might this be enough to provide a foundation for finding my claims "convincing"? Doubtful.
Good thing I'm not depending on convincing anyone my claims are correct. I do hope I can convince critics to attack with well-informed objections to accurate understanding of my ideas, however. That holds the potential for both me and my critic to learn and improve.
