They can say it is scientific because it used scientific techniques.
I'm saying that it can't be trusted. It's not that "science can't be trusted". It's that "not everything can be trusted to be scientific".
Any study paid for by Monsanto goes in my "untrustable" book until it can be independently verified by competent scientists who do not have a conflict of interest and do not rely on any party for funding or publication that has a conflict of interest.
Some studies have leaned away from Monsanto and demonstrably been tampered to lean back towards Monsanto.
So if you're trying to weed out the noise and get down to real science, things don't look good for Monsanto. They don't look terrible for Monsanto until you see how much Monsanto works to bury, obscure, or tamper with real scientific findings. At that point, you bring the hammer down.
