It's false to YOU. Don't be confusing your opinions on second looks to actual fact that there are a lot of programs who care. If there is someone who only had a few interviews this year, it's mean and misleading to tell them not to go on a second look because the programs they interviewed at won't care either way when they potentially would. YOU could be costing someone a bump up on a programs ROL that would come with a second look and possibly cost them a residency and them having to SOAP.
And obviously you're not keen on details, as I have said that many ACP conference PDs I talked to, including the ones on the panel, and every other PD I personally know or that my colleagues have asked have said that it will more times than not get you bumped up on the ROL. Conrad Fischer was just an example, but you obviously believe you're way smarter than him.
I'm going to assume with the attitude from those saying second looks NEVER have an impact on a programs ROL that you're from programs in the Northeast or West Coast. In my experience, and frankly just the known reputation, most medical professionals in these regions are arrogant, borderline narcissistic.
