Agnotology is the study of wilful acts to spread confusion and deceit, usually to sell a product or win favour.
Proctor [who coined the word] found that ignorance spreads when firstly, many people do not understand a concept or fact and secondly, when special interest groups – like a commercial firm or a political group – then work hard to create confusion about an issue. In the case of ignorance about tobacco and climate change, a scientifically illiterate society will probably be more susceptible to the tactics used by those wishing to confuse and cloud the truth.
Another academic studying ignorance is David Dunning, from Cornell University. Dunning warns that the internet is helping propagate ignorance – it is a place where everyone has a chance to be their own expert, he says, which makes them prey for powerful interests wishing to deliberately spread ignorance.
“While some smart people will profit from all the information now just a click away, many will be misled into a false sense of expertise. My worry is not that we are losing the ability to make up our own minds, but that it’s becoming too easy to do so. We should consult with others much more than we imagine. Other people may be imperfect as well, but often their opinions go a long way toward correcting our own imperfections, as our own imperfect expertise helps to correct their errors,” warns Dunning.
