You must appreciate that at the highest level of practice all experts in the same specialty know each other. Leading experts have to mingle at conferences. They move in the same professioanl circles all their life. Think of politicians, presidents of countries. They have personal opinions of each other, positive and negative. They form alliances and they hold grudges. Science is a cuthroat business underneath the surface. Experts may have patent disputes. They may be affiliated with competing technologies or drugs developed by competing pharmaceutical companies. Leading experts move between top-tier hospitals throughout a long career and may have personal and professional disputes. If one expert knows what another expert [with name attached] thinks of the same patient, all the above factors may come into play. They may subtly influence the degree of agreement or disagreement regaridng the interpretation of a patient's situation. Therefore, each expert on a panel that we assemble to review your situation, studies your situation independently of other experts. This further ensures the objectivity of review.
