Challenges of studying visual expertise

Re Mark's assertion that there is a low rate of errors by the visual
experts, I would say that this could vary dramatically in readings of some
rarer cancer readings. In a recent meeting of a network of oncologists,
discussing clinical trial inclusion by cancer subtype, there was a report
of a 50% 'discordance' in the slides provided.  Is there any study to
indicate more broadly how frequently this problem is raised in clinical
trials?

A recent pathology report sent to me, quite lengthy and detailed as to the
description of the cells, nevertheless noted that the cancer was papillary
renal cell carcinoma.  However, there are Type I and Type II papillary
RCCs, each with different prognosis and treatment options.

This is an essential part of diagnosis in cancer, so is a major issue to be
addressed.  Hoping that others might offer resources or insight into this.
