We talk about this in one dedicated section (6). Here there are 2 questions that are conflated, one concerns error-control and the other evidential readiness. Values clearly apply to the second question but should not influence how we answer the first.

But important to note is that convergent evidence can also be misleading in the way consensus can be misleading - if convergence is not robust, namely if the errors of different lines of inquiry are not independent. Convergent evidence then strenghtens bias.

I may have missed the whole context, but the term convergent evidence is more reflective of the inquiry process exactly because it does not misleadingly focus on the social aspect of it, which is a consequence not a cause. When ppl say science is a 'consensual' activity they miss its epistemology.

25/We believe these arguments undermine the epistemic insufficiency thesis. But even if one remains unconvinced, there are further critical problems with legitimate value encroachment, which we explore separately. We'll address those issues in the next thread.

24/Such judgments are fallible—but they are aimed at epistemic values like coherence or accuracy, which are thought to be reliable guides to better hypotheses - while social values have no such property.

23/When scientists judge that one piece of evidence is more compelling than another, or that one method better tracks truth, they exercise epistemic discretion. So, rational disagreement in science is possible.

22/Science progresses because it remains open to challenge and revision. Letting social or ethical concerns lead to premature acceptance or rejection of scientific claims threatens this process, leading to epistemic stagnation masked as social legitimacy or moral progress.

21/The 2nd problem is that when values influence thresholds, they can force scientific questions to settle prematurely, foreclosing debate, testing, and revision. This undermines science’s core virtue: its openness to self-correction.

20/Adjusting the need for scientific rigor based on social value-judgments risks wishful thinking, because one would systematically lower the standards for pet hypotheses and increase them for alternatives.

19/Thus, fallibility presents an ever-present challenge for science—but it is a challenge best met by reinforcing epistemic norms, not by opening inference to moral or social encroachment. Otherwise, we risk 1) wishful thinking and 2)premature closure.

18/ On the contrary, the fallibility of scientific knowledge increases, rather than weakens, the need for epistemic discipline. If science is prone to error, introducing non-epistemic values into evidential reasoning only amplifies risks of distortion and misjudgment.

17/Instead, they merely reaffirm what **fallibilism** already implies: scientific reasoning involves uncertainty, vagueness, and the need for judgment. But good scientific judgment need not involve extra-scientific considerations.

16/Therefore, appeals to arbitrariness fail to establish IRA’s stronger claim: that non-epistemic values must systematically influence the internal inferential standards of science.

15/In fact, **fallibilism** about scientific knowledge already prepares us for this: scientific judgments can be uncertain and revisable, but they can still be disciplined by epistemic norms alone.

14/Vagueness simply means that **reasonable people may disagree** near the margins. It does not mean that there is no right answer, nor that decisions must be guided by external, non-epistemic considerations.

13/Similarly, scientific evidential thresholds ("sufficient evidence") can be vague but they are by no means arbitrary. They are guided by epistemic standards, while open to rational contestation, and they usually reflect a strong disciplinary consensus.

12/The paradox suggests that vagueness leads to indeterminate boundaries, but it doesn't imply that these concepts are arbitrary. In fact, there are many proposed solutions to this paradox, showing that vagueness doesn’t require arbitrary judgments.

11/The Sorites Paradox highlights a problem with vague predicates: if one grain of sand isn’t a heap, and adding one grain doesn’t change that, when does a heap actually form? It challenges how we define thresholds for vague terms like "heap" or "significant effect”.

10/Now, some might argue that because evidential thresholds involve vagueness, threshold-setting must be arbitrary. The classic Sorites Paradox is invoked: when is evidence "enough"? But vagueness alone does not entail arbitrariness.

9/Second, there is **constrained arbitrariness**, where the precise location of threshold is somewhat vague or flexible but it is justified by clear epistemic norms (e.g., reproducibility, accuracy). Scientific thresholds often fall into this second category.
