Meaning

Self-cleansing; self-purification; the capacity of a system to correct or clean itself without external intervention.

A compound noun originally from ecology, describing a river's or ecosystem's natural ability to break down pollutants. In political and organisational discourse it is used to describe an institution's capacity to detect and correct its own corruption or dysfunction — 自浄作用が働く means 'the self-correction mechanism functions.' Its absence (自浄作用の欠如) is invoked as evidence of deep institutional failure.

Examples

1. 組織に自浄作用が働いていれば、あれほどの不正は起きなかっただろう。 If the organization had a functioning self-cleansing mechanism, such widespread corruption would never have occurred.
2. 川には汚染物質を分解する自浄作用が備わっているが、その限界を超えれば機能しない。 Rivers have a natural self-purification capacity to break down pollutants, but once that limit is exceeded, it ceases to function.
3. 政党の自浄作用が問われる事態が続き、有権者の不信感は高まっている。 With the party's ability to self-correct being called into question, voter distrust continues to grow.
