For instance, concerning the delusions in the Science and Factual knowledge areas he writes:
The delusion here is that a society can progress -- or even hold it's own -- by embracing an anti-science position and glorifying ignorance. The delusion consists of the belief that denying scientific evidence or knowledge of facts in general is a good basis for making decisions that affect the public. Whether in the halls of Congress, in the media or on Boards of Education, the delusion of the anti-science/pro-ignorance crowd have increasing influence and impact, as polls indicate. It includes denial of evolution, rejection of the evidence for human-created rise of carbon emissions that creates ongoing climate change, and a general embrace of ignorance as a virtue; that it trumps the usefulness of empirical facts.Interesting although I would add that what seems to be mystifying about the area of factual knowledge is not so much the rejection of such knowledge as the overwhelming nature of the sheer volume and detail of such knowledge. Sources for accurate and trustworthy summarization without distortion could perhaps serve to remedy knowledge rejection......this is as opposed to the "spin" practitioners who pick and choose bits of knowledge to support a position while deliberately ignoring both context and meaning.
I think what I am driving at is that too much information can be as ignorant making and delusion nurturing (in a different way perhaps) as not enough information. There is some sort of Goldilocks principle at work here.
