In scientific research, identifying the causal agent is critical for developing interventions.

Researchers look for causal agents to determine if an intervention should be applied to the subject (like a vaccine) or the agent itself (like boiling contaminated water) [17].

In modern technology, "Causal Agents" refer to specialized AI systems designed to understand and act upon cause-and-effect relationships rather than just simple patterns.

By encoding causal links into their decision-making processes, AI agents can navigate complex environments more safely and handle "distribution shifts" (changes in environment rules) more effectively [22, 10]. 3. Causal Agents in Health and Science
