How Expert Advice Influences Decision Making

Abstract

People often use expert advice when making decisions in our society, but how we are influenced by this advice has yet to be understood. To address this, using functional magnetic resonance imaging, we provided expert and novice advice to participants during an estimation task. Participants reported that they valued expert advice more than novice advice, and activity in the ventral striatum correlated with this valuation, even before decisions with the advice were made. When using advice, participants compared their initial opinion to their advisor's opinion. This comparison, termed the "opinion difference", influenced advice utilization and was represented in reward-sensitive brain regions. Finally, the left lateral orbitofrontal cortex integrated both the size of the opinion difference and the advisor's level of expertise, and average activity in this area correlated with mean advice utilization across participants. Taken together, these findings provide neural evidence for how advice engenders behavioral change during the decision-making process.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Knowing that advice is coming from an expert rather than a novice increases ventral striatum activity prior to actually receiving advice.

    “Specifically, knowing that advice is coming from an expert rather than a novice increases ventral striatum activity prior to actually receiving advice 52.”
  • Value signals in the striatum appear to reflect how we evaluate advice itself (e.g., valuing an expert's opinion).

    “Value signals in the striatum appear to reflect a) how we evaluate the advice itself (e.g., valuing an expert's opinion) 52”
  • Ventromedial prefrontal cortex appears to integrate information concerning advice from others, the validity of the advice, and the value of decision options.

    “Finally, ventromedial prefrontal cortex appears to integrate information concerning advice from others, the validity of the advice, and the value of decision options 3, 52.”

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.
