Why Social Media Data?

The youngest adults stand out in their social media consumption
88% of 18- to 29-year-olds indicate that they use any form of social media.

“Information that comes directly from consumers,
often via social media, is deemed more helpful than data
from reports or government research.”

Longer list of Failures …
LLM
Limited accuracy in complex decision-support requests
ChatGPT showed only 56% accuracy in medical queries (Wei et al., 2023), raising concerns about trustworthiness in clinical use.
Lack of domain-specific expertise
General-purpose LLMs struggle with specialized medical knowledge, leading to errors in diagnosis and treatment recommendations (Szymanski et al., 2024).
Inability to handle & Follow guidelines
LLMs often rely on outdated or incomplete information, failing to incorporate the latest medical research or evolving clinical guidelines (Sheth et al., 2024).
Potential for generating harmful or biased content
LLMs can provide inaccurate or harmful suggestions, particularly if the input data is biased or not representative of diverse patient populations (Gupta et al., 2023).
