The ratchet effect is a concept in sociology and economics illustrating the difficulty with reversing a course of action once a specific thing has occurred, analogous with the mechanical ratchet that allows movement in one direction and seizes or tightens in the opposite. The concept has been applied to multiple fields of study and is related ...
Ratcheting. In continuum mechanics, ratcheting, or ratchetting, also known as cyclic creep, is a behavior in which plastic deformation accumulates due to cyclic mechanical or thermal stress. [1][2] In an article written by J. Bree in 1967, [3] the phenomenon of ratcheting is described as "Unsymmetric cycles of stress between prescribed limits ...

Other terms used to describe this concept include ratchet womanism as used by Georgia Tech professor Joycelyn Wilson or ratchet radicalism used by Rutgers professor Brittney Cooper.

Muller's ratchet. In evolutionary genetics, Muller's ratchet (named after Hermann Joseph Muller, by analogy with a ratchet effect) is a process which, in the absence of recombination (especially in an asexual population), results in an accumulation of irreversible deleterious mutations.

Along with these traits, humans possess much reliance on social learning. [12] [13] This cumulative cultural change or cultural "ratchet" separates human culture from social learning in animals. In addition, a reliance on social learning may be responsible in part for humans' rapid adaptation to many environments outside of Africa.
Dual inheritance theory (DIT), also known as gene–culture coevolution or biocultural evolution, [1] was developed in the 1960s through early 1980s to explain how human behavior is a product of two different and interacting evolutionary processes: genetic evolution and cultural evolution. Genes and culture continually interact in a feedback ...
