Error cascade: a definition and examples

Eric S. Raymond - "error cascade" is medical jargon. Eric defines and gives some examples of what he calls "scientific error cascade", e.g. Anthropogenic Global Warming (AGW).

There an important difference between the AGW rathole and the others, though. Errors in the mass of the electron, or the human chromosome count, or structural analyses of obscure languages, don’t have political consequences (I chose Chomsky, who is definitely politically active, in part to sharpen this point). AGW theory most certainly does have political consequences; in fact, it becomes clearer by the day that the IPCC assessment reports were fraudulently designed to fit the desired political consequences rather than being based on anything so mundane and unhelpful as observed facts.

When a field of science is co-opted for political ends, the stakes for diverging from the “consensus” point of view become much higher. If politicians have staked their prestige and/or hopes for advancement on being the ones to fix a crisis, they don’t like to hear that “Oops! There is no crisis!” — and where that preference leads, grant money follows. When politics co-opts a field that is in the grip of an error cascade, the effect is to tighten that grip to the strangling point.
