Costly Signaling Theory
Explaining altruism through costly signaling
Costly Signaling Theory is a framework that explains how altruism can evolve through costly signaling. It is based on the idea that individuals can signal their quality or resources through costly acts, such as donating to charity or helping a stranger.
- Costly acts can signal quality or resources.
- Others can use these signals to assess the individual's quality or resources.

Donating to a prestigious charity is an example of a costly act that can signal quality or resources. The donor may signal their wealth or status through the donation, and others may use this signal to assess the donor's quality or resources.
Costly Signaling Theory was first proposed by evolutionary psychologists as a mechanism for explaining how altruism can evolve. It is based on the idea that individuals can signal their quality or resources through costly acts, and that others can use these signals to assess the individual's quality or resources.
