1. What constitutes a wrong answer?
2. Who is providing them?
1. Well, if there are multiple conflicting answers, then at least some of them must be wrong.
As I said before, the purpose of the Q&A is to educate people regarding FET. There is more than one FET. Naturally there will be conflicting answers coming from people who believe differently. John Davis will tell you there is no conspiracy, while Tom Bishop simultaneously cries about it, and the newbs watching in awe will come out of it with more knowledge of both theories.
The only type of answer that could be wrong, in this case, is one that doesn't agree with any known FET model; and answers like that are usually corrected pretty quickly by others.
