Finkelstein & Fishbach (2011) examined the effect of expertise on what type of feedback people seek and respond to. They argued that novices who attempt to achieve certain goals are usually still uncertain in their commitment for those goals while experts are usually more stable in their commitment. That is why these authors expected that there would be a shift in the type of feedback people seek and respond to while they gain more expertise with respect to the goal. Their prediction was that novices seek more and respond more to positive feedback and experts seek more and respond more to negative feedback. Finkelstein & Fishbach's hypothesis was that individuals who view themselves as novices primarily want feedback in order to establish whether the goal is valuable and their chance of success is sufficient (the commitment function of feedback). People who view themselves as experts were expected to seek feedback mainly because they want to determine whether they make enough progress (the progress function of feedback).
Finkelstein & Fishbach (2011): expertise shifts the type of feedback which is sought
UsefulnessBecause experts and novices are interested in different types of feedback, it is important to be sensitive to how people view their own expertise when you want to give them feedback. If people view themselves as experts (regardless of whether this is justified) they are probably more interested in constructive negative feedback. Novices, or individuals who view themselves as such, are probably more interested in and motivated by positive feedback.
It is also important to realize that the perception of expertise is subjective and relative. The experiments by Finkelstein & Fishbach demonstrated that this perception can be rather easily manipulated. Answering a list of easy questions can create a perception of expertise while a list of hard questions can do the opposite. In specific situations, like in training programs, in which people wrongly view themselves as having much expertise (this is a realistic scenario considering the Dunning-Kruger effect), it may be useful to correct this perception slightly by using such an intervention.
