Dr Campbell can explains some difficult research papers fairly well but he has one major shortcoming - he does not explain study limitations. For example he may say that this paper found that some drug works for something but he does not stress that it was in vitro study (in the lab) and this is very early to say if it even works when tested on animals. Even worse, he have done the same for results in silico i.e. computer simulations that are not even close to the real world.
