Thanks JC. I would clarify that the CoE requires that scientists "not present themselves as experts outside their areas of expertise". Nothing to prevent them from commenting on other matters with reference to published science - but that is of course true for everyone.

I certainly think of privilege as a responsibility, but think it is important to acknowledge the privilege we have.

Thanks for your points above - they are all very good.

Hi Geoff - no, it isn't universal at all (as Felix says) which is where the suggestion that CRI boards could sign up to support the Code came from. I also agree that it isn't a panacea or a substitute for thinking about those grey areas. I do think that more awareness of the existence of the Code - even more criticism of it, where justified - can only be a good thing.
