I think I would agree with this in part. Where I think the places it becomes problematic for me are the part about “what people accept as true,” and “unavoidable conclusions.” The first is a bit too loose of a criteria for me. Especially with theories I’m of the opinion that there should be some way to rate the objectivity to avoid misrepresenting a theory in a way that isn’t intellectually honest.
To make statements in a way that suggests that a particular position is beyond dispute when in fact it involves a theory with a significant degree of subjective elements to it that seem heavily biased toward a particular paradigm, as I see it, is a current problem in science. And I think the only way to address it is to have a way that gives a general assessment of the degree of subjectivity involved in any particular theory in order for informed decisions to be made about scientific claims, and for helping to facilitate and move forward discussions centered around such claims.
And if by the second part you mean deduction, as far as I can tell, that’s not always possible. I think the most difficulty occurs with things like events in the far distant past, areas that are generally empirically inaccessible, measurements of vast amounts of distance in deep space, etc. There’s generally just too much that has to be assumed to get to a point where deduction becomes possible. In most cases it seems at best the degree of probability can be determined, and even that I would think would be problematic.
