These were promised, but I've not seen them fulfilled. I'll be glad to look at your data, though. The studies you cited, were limited in scope, and short term. Most were single season, and new plantings. Is it conceivable, that planting a novel crop might also initiate other practices that could affect yield? Moreover, this precludes observing the effects of mutated pests and weeds. More moreover, these studies are overwhelmingly on Bt producing crops, so it's not surprising that the cost of pesticides are reduced, since these plants are pesticides, and especially before resistant organisms can proliferate. Consider that the cherry picking was done before I got there. The study may be useful, but it's hardly definitive.

My understanding of golden rice was that it did not yield enough vitamin A to make it effective. (And I am not arguing that "science is wrong..." It always is. I am arguing that any validity of "science" that comes from think tanks is questionable. In my experience, they want to fool us.)

AFAIK, GMO seed companies do not make their seeds available to independent researchers. Therefore no controlled experiments. BTW, do you really think it's unreasonable to have GMOs labeled, and to have some independent testing?
