Why Your Employee Feedback Data Might Be Misleading You

Summary

The widespread accessibility of Large Language Models (LLMs) offers HR and Employee Experience teams new avenues for analyzing employee feedback, from surveys to internal comments, to identify sentiment and themes. However, relying on general-purpose LLMs for this task introduces significant reliability challenges due to their probabilistic nature. Unlike traditional deterministic analytics, LLMs provide "best guesses" that can vary with context, leading to inconsistencies in sentiment scores or topic classifications over time. Additionally, LLM processing can suffer from "batch contamination," where unrelated feedback is misassociated with prevalent issues, and the "lost-in-the-middle" effect, where crucial context in long texts is overlooked. These issues can lead to misaligned engagement initiatives and flawed leadership decisions, underscoring the need for specialized AI tools designed for workforce analytics.

Key takeaway

For Employee Experience leaders evaluating AI solutions for feedback analysis, recognize that general-purpose LLMs introduce significant reliability risks due to their probabilistic nature and inherent biases like "batch contamination" and "lost-in-the-middle" effects. You should prioritize specialized workforce analytics platforms, such as Keatext, that incorporate domain-specific models to ensure consistent, accurate insights for strategic decisions on culture and engagement, rather than relying on potentially misleading DIY approaches.

Key insights

LLMs introduce probabilistic variability and specific biases that challenge reliable employee feedback analysis.

Principles
