Which expert advice
They'll tell you what can't be done, and why. Then do it. Yet it remains true that every great innovation has occurred precisely because someone ignored the experts and went their own way.
You find what we write valuable. I know I find the words of my peers on Management Issues inspiring, informative and helpful. You could drive yourself crazy trying to follow every piece of advice you get. And often the experts disagree. So how is a rational, intelligent and diligent human supposed to take all this advice without their craniums imploding? It was shown that the next day after viewing a celebrity paired with a product, the greater the perceived expertise of the celebrity, the greater the intention to purchase the product and the greater the memory for the product.
This study provided evidence for the implicit influence of expertise on decision making, and although in the present study we focused on the explicit influence of expertise, our results agree with their behavioral findings, showing that people are more influenced by individuals whom they perceive to have more expertise.
Furthermore, conformity to group opinion has previously been shown to recruit the intraparietal sulcus, temporoparietal junction, insular cortex, anterior cingulate, ventral striatum and the lateral orbitofrontal cortex [15] — [17] , [39] , [40]. Importantly, in the most recent study by Campbell-Meiklejohn et al. Thus, our results concerning advice utilization, taken together with this recent publication on conformity, strongly suggest a role for the lateral orbitofrontal cortex in the computation of social influence.
Previous neuroimaging research has investigated aspects of advice taking that are different from the present study. Neural correlates for receiving advice, compared to not receiving advice, have been demonstrated in the dorsomedial prefrontal cortex and the temporoparietal junction [13]. Furthermore, when making repeated decisions with the same advisor and receiving feedback on decision outcomes, the dorsomedial prefrontal cortex and the temporoparietal junction are active during the outcome period [12].
In this second study, these regions computed a social prediction error allowing a person to learn the trustworthiness of their advisor. The septal area demonstrated a greater signal change after both positive and negative feedback from recommended choices compared to non-recommended choices.
The current study did not demonstrate involvement of similar brain regions. However, this is not surprising because we focused on the differences between using expert and novice advice, and not the differences between making decisions with or without advice. Furthermore, we investigated brain activity at the time participants received advice and related it to behavioral change via the weight of advice index. Examining brain activity at the time we receive and utilize advice and relating it to the behavioral change caused by the advice is crucial to understanding how we integrate advice into the decision making process.
In conclusion, with the present report, we demonstrate how people use advice when making decisions. We show that advice-taking consists of three neurocognitive processes: the valuation of advice, the assessment of the opinion difference, and the process of combining valuation and the opinion difference resulting in actual advice utilization.
This last process was shown to occur in the left lateral orbitofrontal cortex, where the average activity correlates with the mean use of advice across participants.
This result establishes the lateral orbitofrontal cortex as a region of the brain responsible for the behavioral influence of advice. As a whole, our findings provide neural evidence for how advice engenders behavioral change during the decision making process, and advance the overall understanding of how humans use advice.

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.
Introduction Many important decisions are made while under the influence of expert advice, from a politician receiving counsel when deciding whether to raise taxes, to a cancer patient being advised by their doctor when deciding whether to undergo chemotherapy.
Experimental Cover Story Participants were told that they would be estimating the monthly rental price of apartments in New York City for a monetary reward. Stimuli Descriptions and price information of real apartments offered for rent in New York City were obtained from www. Procedure Before scanning, each participant was given two training sessions. Open in a separate window. Figure 1. Experimental task.
Figure 2. Behavioral data illustrating the utilization of advice. To address our hypotheses concerning the valuation of advice, the assessment of the opinion difference, and a region of the brain representing the behavioral influence of advice, a general linear model was fit to the data with the following 14 regressors: R1. For the periods of first estimation in the task. For the periods when the advisor was revealed in the task Time 1 : R2. An expert advisor was revealed. A novice advisor was revealed.

Neuroimaging Results The value of advice We hypothesized that the same areas which represent value and reward expectation when receiving money and objects, such as the ventral striatum [6] , also represent value when receiving advice.

The influence of advice We tested the hypothesis that changes in BOLD signal in areas integrating both the expertise level of the advisor and the opinion difference would correlate with the behavioral influence of advice.

Discussion In the present study, we designed a task to emulate real world decision making situations where people form an initial opinion, discover they will be receiving advice along with the expertise level of their advisor , receive advice and then adjust their opinion to make a final decision.
