As soon as Putty's article was published, it attracted a lot of criticism. In addition to the small sample size, his statistical method is still not recognized. Some laboratories tried to do some similar experiments, but they didn't get the results of Puztai. In 2007, Danish scientists fed mice with genetically modified rice for 90 days and found no side effects. In view of Puztai's violation of academic norms, the Lovett Institute expelled him. At that time, Pu Zitai was 69 years old and really reached the retirement age. However, this does not prevent many people from taking this incident as an example of the persecution of conscientious scientists in academic circles.
