In actuality, a person can approach a paradigm shift apart from the community. Kuhn worried that people conflated the "paradigm" with the "scientific community." I believe you may be doing just what he warned against in his postscript here. In this instance, Graham's paradigm which included his understanding of Mormonism was changed by anomalies. A paradigm shift can- nay almost always- involves an individual first before the views spread. In fact, such shifts are generally resisted by the larger scientific community. I believe you have missed this distinction
This will take some work. Let me quote myself a couple days ago, for starters:
Now things get really fascinating here, because a paradigm is supposed to be inspired or based on some kind of famous experiment or discovery.
Now Godfrey-Smith,
In structure, the term is used in several different ways; one critic counted as many as twenty-one different senses. Kuhn later agreed that he had used the word ambiguously, and throughout his career he kept fine-tuning this and other key concepts. To keep thinks simple, though, in this book I will recognize two different senses of the term "paradigm."
The first sense, which I will call the broad sense, is the one I described above. Here, a paradigm is a package of ideas and methods, which, when combined, make up both a view of the world and a way of doing science...But there is also a narrower sense. According to Kuhn, one key part of a paradigm in the broad sense is a specific achievement, or an exemplar. This achievement might be a strikingly successful experiment, such as Mendel's...So paradigms in the broad sense...include within them paradigms in the narrow sense. In Structure, he defined it in the narrower sense. But in much of his writing, and in most of the work written after Structure using the term, the broad sense is intended.
By equating Kevin's changes in opinion with the "narrow sense" would make it virtually worthless to do the work Kuhn wants it to do. People are different, people change over time, but for there to be such a thing as a "normal science", then all these differences have to cancel out to some degree in order to acheive the agreement, the paradigm for the community, the paradigm in the broad sense. In other words, a paradigm reaches deep enough to allow for a lot of opinion changing, self-discovery, originality, and whatever else without actually "shifting a paradigm".
So you are right that a change in paradigm first has to begin with an individual. But you are trivializing the degree to which the individual, in his famous experiment or model, breaks with the status quo. Since shifts in paradigms involve incommensurability, it would make "normal science" impossible if all the Kevin Graham, Scottie, and David B scientists were constantly shifting their paradigms, it's absurd, if "narrow paradigms" shift that easy, then normal science would be impossible as no one would be able to communicate with each other.
From the SEP:
In the postscript to the second edition of The Structure of Scientific Revolutions Kuhn says of paradigms in this sense that they are “the most novel and least understood aspect of this book” (1962/1970a, 187). The claim that the consensus of a disciplinary matrix is primarily agreement on paradigms-as-exemplars is intended to explain the nature of normal science and the process of crisis, revolution, and renewal of normal science.
To quote my earlier self again:
Now things get really fascinating here, because a paradigm is supposed to be inspired or based on some kind of famous experiment or discovery.
So unless you are refering to another "postscript" (not that I remember it distinctly after 6 years anyway) I haven't missed any distinctions.
