The point is that trusting two is not better than trusting one when both of them have equal chance to be malicious.

May be, but we can try to call a spade a spade and not pretend that something is more trustworthy than it is.
Is A has a p chance of being malicious and B has a q chance of being malicious then the chance of them both being malicious is pq. pq <= p and p*q <= q.
I'm honestly not sure why its so hard for you to understand that TWO people being malicious at the same time is less likely than either being mailicous on their own.
> both being malicious is pq.
Not if p -> q. If p is malicious, a malicious q is most probably maliciously picked by p to review this study.
