RS 'fatheads' 1

I have a question for the anonymous fellow who said Susan Greenfield's possible appointment to the Royal Society was "an insult to the world-class scientists who are still on the waiting list" ("Royal Society fellows threaten to resign if Greenfield joins their club", February 6). If her work is so limited, why won't you make your criticisms explicit and sign your name?
