Confidence and certainty: Distinct probabilistic quantities for different goals

Open access
Pouget, Alexandre, Drugowitsch, Jan, Kepecs, Adam·2016·Nature Neuroscience

Abstract

When facing uncertainty, adaptive behavioral strategies demand that the brain performs probabilistic computations. In this probabilistic framework, the notion of certainty and confidence would appear to be closely related, so much so that it is tempting to conclude that these two concepts are one and the same. We argue that there are computational reasons to distinguish between these two concepts. Specifically, we propose that confidence should be defined as the probability that a decision or a proposition, overt or covert, is correct given the evidence, a critical quantity in complex sequential decisions. We suggest that the term certainty should be reserved to refer to the encoding of all other probability distributions over sensory and cognitive variables. We also discuss strategies for studying the neural codes for confidence and certainty and argue that clear definitions of neural codes are essential to understanding the relative contributions of various cortical areas to decision making.

  • Propositional confidence can be distinguished from other confidences or uncertainties inherent to perception, cognition, and action, although the latter often inform the former.

    “The most important idea, building on the work of Pouget et al. (2016), is that propositional confidence can be distinguished from a myriad of other confidences or uncertainties that are inherent to perception, cognition, and action, although the latter often inform the former (Meyniel et al. 2015).”

  • The data favors the interpretation that TRI produces a "positivity effect" on user judgement, rather than an "uncertainty-reduction effect".

    “The data favors our interpretation that TRI produces a “positivity effect” on user judgement, rather than an “uncertainty-reduction effect” (cf. [59]).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
