He claims to be an autodidact, as am I.
However, NDD doesn’t realize you can still be a poor student. He lacks open-mindedness, and the ability to look at everything with a healthy dose of skepticism. He’s too passionate and bound to the political basis of his arguments and his philosophical ideologies to learn anything new in an “honest-with-himself” way.
He doesn’t have the ability to shed himself of his biases and bigoted notions, so he’s limited himself to only accept the sources that confirm his biases. He can’t see this, because he also has no understanding of how the scientific method works in the general sense, let alone its much finer points.
In fact, he may be anti-scientific which has zero place in academia, or any legitimate school of thought.
Only in a very cursory manner has he familiarized himself with logical fallacies, but doesn’t completely understand them, nor know when to apply them: First examine your own thinking or arguments for these fallacies, as in the case of Special Pleading, you are never expect from any these.
He’s not careful or rigorous in his research, and can’t distinguish between reports or studies of high or low veracity. His interpretation of data has been shown to be egregiously faulty.
But most of all, he has a God Complex, and lacks humility. He starts from the assumption he’s right, and knows the truth, so this automatically filters his perspective and he shoe-horns data and “facts” into his world-view to force it to align with his preconceived notions.
He’s a bigot and an anti-intellectual, and the people he comes into direct interaction will be the worse for it, and he will die that way never to be aware.
So, from one autodidact to another, I grade NDD an F+.
