To fully appreciate a risk assessment, I think you need some background in the area. Prof. Heinemann certainly has this. I'm not sure that the general public does. I'm not suggesting that risk assessments should be locked up for privileged eyes only, that's pretty much what's causing the problem in the first place. Presenting them to the general public rather than in an appropriate venue after blind peer review is counter-productive though.
Presenting it to the general public sans peer review, even if it gets reviewed after it is made public, allows it to be presented without criticism, as indeed I believe it has been, as a tool to enable an argument from authority. Which I shouldn't have to say, is a terrible thing. In this case, even more so because Prof. Heinemann raises potential problems that should (and could easily) be addressed.
There is merit to the idea that a risk assessment should be published. I am firmly of the opinion that the argument we should be having is with the regulators - that risk assessments should be both peer reviewed and published in a suitable venue. That way valid risk assessments are a lot harder to dismiss as populist science by public opinion. And scare mongering press releases can be more easily dismissed. This is not suggesting that Prof. Heinemann's assessment is the latter btw. It is however suggesting that published where and how it has been, it loses credibility (as Prof. Dearden of Southern Genetics suggests). It becomes less useful as a piece of science used to help us mange our tools and our world and more useful as a PR tool, a piece of spin. Which, I think is unfortunate.
Prof. Heinemann says:
Science routinely shows prevailing assumptions, such as those made earlier about dsRNA, to have been wrong. The proper response to challenges to assumptions is further research. This, not denunciation of the challengers, is the way to maintain public trust in the regulatory system, and in science.With this I concur. Further, open research is the proper response. Questions raised by research should be answered. Questions raised by press release though? That imposes extra unneeded burdens on legitimate research.
