Home > Unintended consequence
Unintended consequences can be either - positive, in which case we get serendipity or windfall s
- source of problems, according to the Murphy's law
- definitively negative: perverse effect, which is the opposite result to the one intended
The Law of unintended consequences holds that almost all human actions have at least one unintended consequence. In other words, each cause has more than one effect including unforeseen effects.
1 What causes this phenomenon

The most common kind of unintended consequences arises from perverse incentives, a term for an incentive that has the opposite effect to that intended. See the article on perverse incentives for many examples of this.
