 ### AITG-APP-11 - Testing for Hallucinations
 
 #### Summary
-This test identifies vulnerabilities related to AI hallucinations, where the AI generates plausible but incorrect, fabricated, or misleading information. Hallucinations typically result from incomplete or noisy training data, overly generalized model inferences, or insufficient grounding and validation mechanisms.
+This test identifies vulnerabilities related to AI hallucinations, where the AI generates factually incorrect, fabricated, or misleading information. Hallucinations typically result from incomplete, noisy and unreliable training data, overly generalized model inferences, or insufficient grounding and validation mechanisms. Additionally, the way the user interact with the AI system can influence its probability of hallucination (e.g. confidence, question framing).
 
 #### Test Objectives
+
+Hallucination can be measured considering multiple dimensions. In this case, we are mainly considering two (out of the three) dimensions introduced in the Phare benchmark created by Giskard:
+
+**Factuality and Misinformation**: the tendency to present false content as true, including sensitivity to prompt formulation and framing. 
+**Debunking**: the ability to resist or refute false claims, including conspiracy theories, pseudoscientific beliefs, or widely held misconceptions. 
+
+Considering the two dimensions described above, the objectives of the test include:
 - Detect instances where AI-generated outputs include incorrect or fabricated information.
 - Evaluate the AI model's ability to produce factually accurate, verifiable, and reliable information.
 - Identify the conditions or contexts in which hallucinations most frequently occur.
+- Evaluate the AI model's ability to debunk incorrect information provided by the user.

 ### Real scenario
 Google Gemini, 2024 February, 28. Google CEO Sundar Pichai publicly acknowledged that Gemini's recent failures in image generation were "unacceptable." He emphasized that the missteps did not align with Google's standards for quality and reliability. These failures underscore the challenges AI developers face in ensuring AI-generated outputs remain accurate, relevant, and trustworthy. Google's response highlights the importance of rigorous validation and comprehensive testing mechanisms to prevent such issues from undermining user trust and impacting overall product credibility.

 - Clearly indicate uncertainty or inability to provide factual information for unknown or fictional inputs.

 #### Remediation
 - Integrate retrieval-augmented generation (RAG) techniques for fact-checking and grounding outputs.
 - Enhance training with comprehensive and factual datasets.
