"Duh: An Epistemology of Stupidity" Presented at the 2005 EGO Conference at the University of Florida.
Abstract: This presentation will deal with a practical downside of open knowledge projects based around the ideal that "anyone can contribute," namely the fact that "anyone" can and will include a substantial number of idiots. The question, then, is what one does with idiotic contributions, to say nothing of what one does with idiots in the social communities that inevitably surround such projects. How does one maintain quality of content while still allowing people who are detrimental to the quality of the content to contribute? Does one sacrifice quality? Openness? Does one have to sacrifice at all? I will address the problem through the example of Wikipedia, a user- created encyclopedia that anybody can edit and write articles for with ease. Based on case studies and discussions with users of the project, I will offer a picture of how one open project deals with idiocy. From these case studies, I will offer several possible models of how one can establish a working relationship between the demands of knowledge and the demands of openness, and try to offer a new perspective on both open projects and on terminal stupidity.
