Declinism is a perception, often seen in societies or individuals, that there is a continuous, irreversible decline in the current status of society, culture, or civilization.
It typically involves a negative outlook on the future or a belief that progress is coming to an end or reversing.
Declinism can manifest in various ways, such as pessimism about economic, political, or social conditions, dissatisfaction with cultural values or morals, or even apocalyptic fears.
Some argue that declinism can lead to a self-fulfilling prophecy, as the belief in decline can discourage action towards progress and improvement.
