Information hazards are reasons to withhold knowledge, such as how to build an atomic weapon, the genetic makeup of deadly viruses, etc. The idea is not new.

Anarchist, atheist, buddhist, extropian, libertarian, mormon, singularitarian, technoprogressive ... and cosmist are among the many self-identifications that sometimes accompany transhumanist self-identification.
