To be effective, experts need to simultaneously develop others (i.e. provide advice and feedback to novices) and advance their own learning (i.e. seek and incorporate advice and feedback from others). However, expertise, and the state of efficacy associated with it, can inhibit experts from engaging in these activities or doing so effectively. We discuss when and why cognitive entrenchment and reduced perspective taking lead experts to hold misperceptions about others. We then explain how these misperceptions lead experts to provide less helpful advice and feedback to novices and to be less likely to seek and take input from others. We offer insights to overcome these barriers, enhancing experts’ ability to provide and propensity to seek advice and feedback.
