I would like to describe to you a discourse that I sometimes hear on the interweb. It has the following features.
1) It is dominated by people without training or expertise in the matter under discussion.
2) When people with training or expertise in the matter under discussion observe that what is being said is highly problematic those without training or expertise in the matter under discussion invariably act as if they have better knowledge on the matter under discussion.
3) Every statement made by those without training or expertise on the matter merely confirms to those with such training and expertise that in point of fact these persons without training or expertise on the matter are ignorant and clueless of the matter.
4) The conviction that their untrained ignorant exceeds trained knowledge is a sure sign of hubris, and has potential to contribute to disastrous policy decisions when it comes to what should be taught in schools. As such all who care about quality of education should be concerned with this discourse.
Now, I am going to list a number of discourses, and will ask you to identify which is the one of which I speak.
A) Young-earth creationism.
C) 9/11 Trutherism.
D) Holocaust denialism.
E) All of the above.
If you answered "E," you pass!
