I submitted a request for clarification to firstname.lastname@example.org for the following policy:
Indicate that a URL for a publication list is optional and, if provided, must be to a government website (.gov) like My Bibliography.
This was in response to recently updated instructions for preparing the biosketch and some discussion on Twitter initiated by @crytogenomicon.
After about a week, I got the following reply:
With broader rules for including links we could not protect the anonymity of our reviewers.
It took me a few minutes to process this result, and then it hit me. I could link, for example, to the publication list on my personal lab web page. I use Google Analytics, and thus I can see where traffic to my site originates from. It would be very simple to figure out who reviewed my grant in this scenario. Turns out @thatdnaguy was right!
