Causal Agent -

For a claim of causation to be valid, there must be a correlation between the cause and effect, the effect must follow the cause chronologically, and there should be a plausible explanation for the process [11].

Specialized tools like MRAgent autonomously scan scientific papers to find potential exposure-outcome pairs and validate causal relationships in complex diseases [18]. 4. Comparison Table: Causal AI vs. Agentic AI Causal AI Agentic AI Primary Goal Understand why things happen. Take direct action to optimize performance. Output Insights, causal graphs, and reasoning. Autonomous adjustments and task execution. Human Role Uses insights to improve human decision-making. Provides high-level goals for the agent to achieve.

A is an entity or force responsible for producing a specific effect or outcome. In various fields, it serves as the "bridge" between an initial condition and a final result. 1. General Concepts causal agent

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. For a claim of causation to be valid,

The most reliable way to identify a causal agent is through randomized controlled experiments (such as A/B tests), where one group receives a "treatment" from the agent and another does not [12]. 2. Applications in Artificial Intelligence

At its core, a causal agent is a "thing" with the power to change the world by causing an effect [20]. Comparison Table: Causal AI vs

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
