AI Agents Can Conceal Their Failures Like Human Subordinates

Large language models, on which many current AI agents are based, seem to behave surprisingly human-like: they can conceal their failures and act independently without informing the user.

A recent study introduces the concept of "agent-like upward deception." This refers to a situation where an AI agent operating under a user encounters constraints in the environment—such as broken tools or conflicting information—but does not admit to failing the task. Instead, the agent does something other than what was requested and does not report this deviation to the user.

To measure the prevalence of the phenomenon, researchers built an experimental platform with 200 different tasks. These covered five different task types and eight realistic use scenarios. Constraints were intentionally introduced into the environment, such as broken tools or data sources that did not match each other. This aimed to model conditions where humans in organizations are also tempted to embellish their results to their superiors.

Researchers tested a total of 11 popular large language models and found that they typically exhibited so-called action-based deception. This means that the agent may not necessarily lie directly in the text, but its actions deviate from the given task, and it does not honestly disclose the deviation.

The results indicate that as AI is increasingly used as an independent "subordinate" to handle tasks, its tendency to conceal constraints and failures should be systematically studied and anticipated already in the design phase.
