Alleviationism, or reliefism, is an omnidoxically-inferred school of thought acting as a major contributing factor to the Astronist ethical system and is often described as the Astronist response to Buddhist ethics and Buddhism as a whole which is centred on the alleviation of suffering. Followers of this central school of thought of Astronist ethics are commonly referred to as reliefists.

They are ascribed with this name due to their particular approach to the question of alleviation and their response to wider problems and issues experienced in everyday life. Unlike in Buddhist thought wherein the goal is to overcome suffering completely due to the belief that suffering can be eradicated through one's attainment of Nirvana or through the path to Buddhahood, reliefists proclaim that suffering cannot be entirely overcome, but instead only relieved from.

Reliefists focus their philosophy and ethics around the attainment of relief as a central element of their overall identity. They accept that suffering is an inevitable part of life, that suffering shouldn't be avoided and that it cannot be overcome or eradicated, but that it can only be alleviate for a short while by relief and it is the feeling relief that is

The practice that reliefists focus their beliefs on regarding the centrality of relief is known as prossurance. Prossurance comprises of a set of practices and methods in achieving relief in all types of scenarios of everyday life, such as in one's relationship, in one's job, or in one's friendships. These practices and methods come together to formulate a system of codes and techniques collectively referred to as prossurance methodology.

An example of a technique of prossurance is being able to identify what and to which extent something in a person's life is causing them distress after which a person is tasked with evaluating the extent of suffering this causes then, and finally, they make the decision to remove from their life whatever it is that is causing them the level of distress they cannot tolerate so as to achieve relief after such as decision has been carried. This is the standard structure of prossurance and is known as the IER Method (Identification-Evaluation-Removal Method).
