The study on the ill-effects of consumption of genetically modified potatoes that your writer alludes to was unpublished, and thus not subject to peer review. This latter discipline is important as a safeguard for the trust we put in the results of scientific discovery. The methodology of this study could never have substant-iated the claim made since it did not use genetically modified material. As a scientist who has become an organic grower, I despair at the polarisation and vilification that has characterised this issue. Surely we can find better ways to judge whether there are any merits in scientific innovation?
