Decoding Intentions: Artificial Intelligence and Costly Signals

Private sector companies lead much of the innovation in AI, but their motivations and incentives may diverge from those of the state in which they are headquartered. As governments and companies compete to deploy evermore capable systems, the risks of miscalculation and inadvertent escalation will grow.

Costly signals are statements or actions for which the sender will pay a price —political, reputational, or monetary—if they back down or fail to make good on their initial promise or threat.
