1998 John Baez
Crackpot index - Wikipedia, the free encyclopedia: "The crackpot index is a number that rates scientific claims or the individuals that make them, in conjunction with a method for computing that number. The method, proposed (most likely as a joke) by mathematical physicist John Baez in 1992, computes an index by responses to a list of 37 questions, each positive response contributing a point value ranging from 1 to 50. The computation is initialized with a value of −5. Presumably any positive value of the index indicates crankiness. Though the index was not proposed as a serious method, it nevertheless has become popular in Internet discussions of whether a claim or an individual is cranky, particularly in physics (e.g. at the Usenet newsgroup sci.physics), or in mathematics. Chris Caldwell's Prime Pages has a version adapted to prime number research which is a field with many famous unsolved problems that are easy to understand for amateur mathematicians."
