Crackpot index

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. While the indices have been created for their humorous value, their general concepts can be applied in other fields like risk management.[1][2]

Baez's crackpot index

The method, proposed semi-seriously by mathematical physicist John C. Baez in 1992, computes an index by responses to a list of 36 questions, each positive response contributing a point value ranging from 1 to 50. The computation is initialized with a value of −5.[3] An earlier version only had 17 questions with point values for each ranging from 1 to 40.[4]

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[5] which is a field with many famous unsolved problems that are easy to understand for amateur mathematicians.

Gruenberger's measure for crackpots

An earlier crackpot index is Fred J. Gruenberger's "A Measure for Crackpots"[6] published in December 1962 by the RAND Corporation.

gollark: Or some sort of non-permission-enforcing boot mode for the same OS, sure.
gollark: But anyway, you can't do it without booting into another OS unless you have a macOS zero-day or something which you don't.
gollark: I generally avoid trusting people who specifically claim they can be trusted because X.
gollark: Unless you're one of those people who doesn't do backups.
gollark: Meh, it's not that bad with computers since stuff can mostly be fixed with no cost except time.
