- Half-life_of_knowledge abstract "The half-life of knowledge is the amount of time that has to elapse before half of the knowledge in a particular area is superseded or shown to be untrue. The concept is attributed to Fritz Machlup (1962). For example, Donald Hebb estimated the half-life of psychology to be five years.The half-life of knowledge differs from the concept of half-life in physics in that there is no guarantee that the truth of knowledge in a particular area of study is declining exponentially. It is unclear that there is any way to establish what constitutes "knowledge" in a particular area, as opposed to mere opinion or theory. This is similar to the concept of a half-life of facts coined by Samuel Arbesman, a Harvard mathematician and scholar at the Kaufmann Foundation.Because scientific knowledge is growing by a factor of ten every 50 years, this means that half of what scientists may have known about a particular subject will be wrong or obsolete in 45 years.".
