defection

Abandoning one's allegiance

Defection is the act of abandoning a cause, country, or allegiance—typically to join an opposing side.

The word implies betrayal: a spy's defection to an enemy nation, a politician's defection to a rival party.

Several members defected to the opposition after the scandal.

In game theory, defection means choosing self-interest over cooperation.
