Diversity of epistemic practices: toward solving the puzzle

My prior post about metacognitive diversity pointed to the difficulty of reconciling invariance in procedural and analytic metacognition with the high variability in predictive practices. In this post, I attempt to address the puzzle itself. How can the coherence between the three sets of data be restored? My strategy will be to explore the procedural underpinnings of both B and C type of evidence, and show that the same kind of basic process explains them. Let us first consider the universality of Gettier and similar epistemic intuitions.

About epistemic intuitions

A standard way of explaining universality in intuitions consists in drawing on Chomsky’s own argument: Universality in syntactic intuitions is claimed to derive from the existence of a universal grammar that is hard-wired into the brain. A nativist theory about how children use and develop their concepts similarly claims that all humans rely on an intuitive mental lexicon when forming their spontaneous inferences in a variety of domains, such as folk biology, folk psychology (mindreading), numeracy, in addition to folk epistemology. My present goal is not to discuss the validity of a nativist conception of any of the core domains of knowledge.

What should be pointed out is that intuitions are not identical to spontaneous inferences. As discussed in the first post, intuitiveness is a metacognitive feeling, and hence, does not properly belong to the content of the first-order inference that feels intuitive. Intuitiveness is rather generated by the comparatively higher fluency of the processing sequence underlying the inference. Higher fluency, however, does not exclusively belong to  innate informational processes. Various types of experimental manipulations of fluency such as implicit learning, repetition, experimental priming, have been shown to selectively increase intuitiveness of a judgment as well as one’s confidence in its validity. (Topolinski & Strack, 2009). Metacognitive feelings based on fluency, then, determine our preferences for using specific concepts, our dispositions to detect the semantic value of a definition, or the coherence between several claims.

Truth evaluation across cultures

How do people proceed to discriminate whether P is true? According to the eminent metacognitive scientist Norbert Schwarz, people ask themselves one or more of the following questions: (1) Do others believe it? (2) Is there plenty of evidence to support it? (3) Is it compatible with what I believe? (4) Does it tell a good story? (5) Does it come from a credible source? (Schwarz et al. 2016). In other words, people primarily assess consensuality, evidentiality, coherence, relevance, and source credibility. If P scores high on several of these dimensions, a thinker will tend to believe it is true; if P scores low, it will be held false. Note that the case of the “consensually wrong”, studied by Koriat (2008), does not contradict Schwarz’s view: both speak about what constitutes sensitivity to truth, not about truth. (Keep in mind this observation, we’ll need it later.)

How does this analysis affect the nature of epistemic intuitions? It appears that the epistemic judgments elicited by the experimental philosophers are generated by a heuristic combination of features 1 to 5. These features have been selected, not (I venture to claim) because we share an innate folk epistemology, but because we all converse, and learn converging standards of evidentiality and relevance when we do. In this process, we assess our own subjective confidence in what others tell us, using a polar scale of intensity and valence (from no confidence to full certainty.) According to the conversational normative patterns of our group, we will tend to weigh, for example, consensuality higher than evidentiality (or reciprocally). Even when trusting consensus and testimony, we will have had enough experience to know that they may occasionally fail to be reliable. For example, when you’re told that your wife is at the hospital, it’s likely to be true: why would people lie to you? But there might indeed be several Mrs Jones. Wait until you see her to be certain she is in this hospital, to report that you know where she is.

To summarize this point: we need only to assume that the same informational constraints apply to conversation across populations for explaining that the pattern of reporting/attributing knowledge should tend to converge at the limits of the evaluative scale (knowledge/ignorance). Hence they might converge when attributing a positive value to a true utterance and a negative value to a false utterance. Convergence does not need to extend to the desired level of informativeness. Human groups have different rules concerning who deserves to be informed, and who does not. How then, can this analysis solve the puzzle of the diversity in epistemic practices?

The Azande’s oracle  and truth

Recall that the Poison Oracle in Azande claims to form predictions “beyond doubt.” Practitioners find the oracular practice to fulfill all the demands that laypeople from the West place when attributing reliability in a method aiming to truth: (1) it is consensual (2), it is based on evidence, (3) it is coherent with what people believe, (4) it is relevant (i.e. highly informative about an important matter) and (5) its source – “the Poison” is trustworthy. Note that these conditions always apply as a function of a specific social and epistemic pattern of practices. As proposed by Bloch (2008), divinatory practices are trusted in many traditional societies because, in contrast with testimony, their outcome can be perceived, and cannot be easily manipulated. Coming back to my former question in post 3: why do people consider a lethal outcome as caused by the response of the oracle rather than by poison alone? It is quite likely that there is no observable regularity between the quantity of substance ingested and the consequent death, because the effect of the poison depends both on the plants harvested – toxicity is likely to differ widely across samples – , and on the age and health condition of the victim. The Azande, furthermore, notoriously superimpose an intentional to a causal account for each significant event of their lives. Yes, the poison is lethal, but this does not suffice to explain this particular death at this particular moment. Hence, the poison is treated intentionally, in coherence with a local consensus. A final aspect of the epistemic process can only be mentioned here, although it deserves more space. Why does it seem important for the assumed reliability of the poison oracle that both the questioner and the practitioner should respect sexual abstinence several days ahead of time? Sexual abstinence might be a factor of trust; sexual abstinence might constitute both a salient and a fluent social rule for elevating confidence in social practices endowed with an epistemic authority. Westerners might fall prey to a similar pressure of a salient social rule when applying an equality rule in epistemic decision making, irrespective of the variable expertise of participants. (Mahmoodi et al., 2015). Both rules (sexual abstinence and equality) reflect consensual patterns of practices, which, being fluent, seem to be truth-conducive. But they both instantiate a case where people are consensually wrong. As shown by Koriat,  however, consensuality about wrong rules, correlates with the participants being highly confident of being right to apply them.

In summary, I have argued that feelings of fluency play a major role in eliciting in participants a sense of the truth-conduciveness of the oracle. When a social predictive practice is based on locally accepted concepts, often consulted, difficult to manipulate, easy to understand, rich in affect, relevant to individual and social welfare, backed up by local social rules or taboos, its outcomes tend to be assessed as true. This heuristic allows for quite diverse practices to be trusted across cultures. This diversity, however, does not suggest that the concept of truth itself varies across practices. Nor does it exclude that ways of collecting evidence should not, when education and knowledge develop, be subject to more precise epistemic scrutiny.

  1. Hi Joëlle,

    Thanks for these very engaging posts! As you know, I very much agree with your view that intuitions are non-propositional metacognitive feelings and with your interpretation of the data that would support this view. (For people who haven’t seen it, Marcus McGahhey and I have a new paper coming out that touches similarly on Gettier intuitions, which can be found here: https://www.academia.edu/26087602/Interpreting_Intuitions .)

    I did have one question about how to interpret the Azande practice of divination by chicken poisoning. Could it be that the social function of this practice is not genuinely *epistemic*? Here’s my thought. Often, we humans are in a situation in which we have to make plans about an uncertain future. And in these situations, it may make sense to form what Michael Bratman calls an *acceptance in a context*–basically, an assumption about how things will be that doesn’t rise to the level of belief–which can then be the cognitive input into action choice. Furthermore, for joint actions, it can help coordination to accept the same things as fellow actors. With this in mind, it is possible to see divination as a social mechanism for producing joint acceptance, even if at first glance it *appears* to be an epistemic practice. One might put it like this: “We don’t know what to assume about the future for purposes of action, so let’s just go with what the Oracle says.”

    I realize this approach would involve interpreting differently a number of the utterances made by the Azande in the course of the divination practice. I am also no expert on the Azande. But it does appear to me that the approach I just proposed has certain theoretical advantages. In particular, it alleviates (at least in one instance) the tension between topics A and B, on the one hand, and topic C, on the other. A and B suggest epistemic and metacognitive similarity across cultures, while C suggests radical diversity. So if some of the apparent radical diversity turns out not to be in epistemic practice at all, that would alleviate some of the tension with A and B, which are about genuine epistemic and metacognitive practices.

    Does this approach seem promising?

    All the best,
    Neil

    Hello Neil,

    Let me first tell you how much I like your new paper with Marcus McGahhey on Gettier intuitions. Your way of deriving both the invariant and the variant parts of these intuitions from their non-propositional character is quite convincing.
    Thank you for providing a comment offering an alternative proposal to the diversity puzzle. To the extent that your proposal seems to dissolve the inconsistency, it is prima facie quite attractive. At a closer look, it seems to bring with it its own puzzles. It decomposes into two premises and a conclusion, which I will briefly discuss.
    a) “Azande’s divination practice might be a form of “accepting in context””.
    This is a propositional attitude that you are supposed to hold merely for the benefit of action, “even if you know it to be false” as Stalnaker proposes. In chapter 8 of The Philosophy of Metacognition, this notion of acceptance is objected to for failing to offer a coherent picture of the mental action of accepting and of its role in practical reasoning. Blurring the distinction between epistemic and instrumental norms is an epistemic disaster: imagine a map that you use, across contexts, either because it’s true or in spite of its being false! Clarification of this notion, I think, requires distinguishing an epistemic from a strategic form of acceptance.
    b) “Accepting in context is not a genuine epistemic practice.”
    Understood in a narrow sense, “epistemic” means: “accepting as true” (a belief is involved); understood in a wider sense, “epistemic” means: “aiming at knowledge acquisition.” On this sense, procedural metacognition is epistemic (even with no belief about the evaluative process involved). In which sense of “epistemic” is this premise needed to alleviate the tension between A & B, on the one hand, and C, on the other?
    You’re right to claim that an epistemic practice may not be used in a fully reflective sense of “epistemic”. It is difficult to maintain, however, that the Azande do not expect their divinatory practices to generate knowledge at least in the wide sense of “epistemic”. Mere coordination of the kind “Let’s go with what the oracle says” amounts to throwing dice about matters of life and death. It does not fit what Evans-Pritchard reports about the Benge practice.
    c) Conclusion: “Divinatory practices do not need to conflict with procedural metacognition or epistemic intuitions because they are not epistemic, or at least they are not perceived as epistemic by their practitioners.”
    One can perfectly admit that there are many ritualized practices that, even when they look epistemic from an external viewpoint, are merely ways of coordinating with others. For example, reciting “Credo” does not need to involve credence, confidence etc.. It is difficult to claim, however, that the Poison oracle is merely “the thing to do”, with no epistemic justification for its being consensual. If divinatory and other irrational practices did not have an epistemic goal, there would be no point to questioning their epistemic reliability. They would never be seen as conflicting with other predictive methods.

  3. Thanks for the response, Joëlle. For me, the last sentence of your response contains the telltale sign that a practice is (probably) more than just a means of producing acceptance in a context. If the divination were merely a means of producing acceptance in a context in a situation of uncertainty, other predictive methods would most likely trump the output of the divination, as opposed to being seen to conflict. I personally have a hard time imagining doing such a thing as an epistemic practice, but that’s why it’s good to read anthropology!
