Sprague-Dawley rats have a lifespan of about two years and have a high tendency to get cancer over their lifespan (one study found that over eighty percent of males and over seventy percent of females got cancer under normal conditions).[37][38][39] The Séralini experiment lasted the normal lifespan of these rats, and the longer the experiment goes, the more statistical “noise” there is - the more rats get cancer naturally, regardless of what you do to them.
So for the experiment to have adequate statistical power, all the groups - control groups and test groups - would have to include at least 65 rats per group in order to sort out any experimentally caused cancers from cancers that would occur anyway - but the Séralini study had only ten per group
since Sprague-Dawley rats are susceptible to mammary tumors when food intake is not restricted, data should have been provided about how much food the rats were fed (as well as the presence of fungus in the feed, another confounder). Sanders also wrote of this study, “The statistical methods are unconventional ... and it would appear the authors have gone on a statistical fishing trip
Genetic modification of plants has been used for a long time. I guess people have to have a monster under the bed and a conspiracy around every corner. This time it’s GMO.

We have seen what happened when people with an agenda scared people into not vaccinating their children. This kind of hysteria causes real harm.
