Agreed and this is where I think that the comparison between us and medicine breaks down a bit. I think that most of the corpus of medical knowledge resides in significantly closer proximity to the 'bedrock' of the natural sciences (around which there is near universal consensus in medicine) and, thus, may be more reliably assessed (even at higher levels of complexity and specificity). The "convergent" nature of the process of demonstrating adequate understanding of the Krebs Cycle on a multiple-choice item, for example, is different than the 'divergent/creative' and highly context-dependent nature of demonstrating masterful application (in context of practice) of agreed-upon (roughly) theories in clinical psychology. Not saying it's impossible...but it will be challenging.
