ChatGPT:
Chatbots as “Stochastic Parrots”: A Critical Exploration by Emily Bender
🌐 Introduction: The Rising Debate on Large Language Models
As AI-powered conversational agents like ChatGPT become embedded in our daily lives, questions about their ethical, practical, and theoretical implications have intensified. Linguist Emily M. Bender, a professor and the director of the Computational Linguistics Laboratory at the University of Washington, is a prominent voice challenging the current trajectory in AI. In her landmark paper, Stochastic Parrots (2021), co-authored with Timnit Gebru, Angelina McMillan-Major, and Margaret Mitchell, Bender argues that large language models (LLMs) like ChatGPT mimic language without true understanding, making them “stochastic parrots.” In recent discussions, she critiques the technological, ethical, and social implications of large-scale LLMs, which she argues lack real comprehension, introduce systemic biases, and raise labor and environmental concerns. Bender’s insights question whether larger AI models necessarily mean better models and advocate for a stakeholder-centered approach to AI development.
🔍 The Foundation of “Stochastic Parrots” and Its Warnings
The Original Warning in Stochastic Parrots
In 2021, Bender and her co-authors warned of the risks associated with the rapid expansion of LLMs. Her primary argument was not a prediction of technological inevitabilities but a warning against continuing a path that prioritizes larger and more resource-intensive models. Bender emphasizes that these models lack fundamental understanding of language and meaning. As the technology evolved, these warnings have proven increasingly relevant, as developers chase scale and realism in AI systems without addressing foundational shortcomings or ethical issues.
The Exploitative Labor Behind LLMs
One dimension Bender had not fully anticipated in her original paper was the degree to which human labor would be exploited to create and refine these models. As LLMs grew, companies relied on human contractors to annotate data, rate responses, and moderate content—a process essential to training and maintaining these systems but often performed by workers in low-wage positions, sometimes with poor working conditions.
The Hype and Misplaced Enthusiasm
Bender also underestimated the extent of the public’s enthusiasm for AI-generated synthetic text, which in her view often obscures the true nature of these technologies. While the fluidity of synthetic text may impress, she argues that it leads to a misplaced belief in the technology’s capabilities, contributing to what she views as an unjustified “hype” around these systems.
🚀 Scaling Models: Does Bigger Mean Better?
The Problem with Scale
Bender questions the prevailing belief that bigger LLMs inherently mean better results, arguing that scale improves the ability to mimic human language but does not enhance the actual understanding or task-specific utility. She references Claude Shannon’s work in the 1940s, which laid the groundwork for probabilistic language modeling—used for practical tasks like transcription or spell-checking—but she argues that LLMs have gone far beyond what’s needed for such applications.
No Clear Evaluations for Specific Tasks
According to Bender, there is a lack of rigorous evaluations that demonstrate significant performance improvements on specific, practical tasks due to LLM scaling. Instead, the primary result of larger models is better mimicry of human-like responses, which she argues serves limited practical purpose without genuine understanding.
🧠 “Stochastic Parrots”: Mimicry Without Comprehension
Linguistic Foundation of “Stochastic Parrots”
Bender draws on linguistic theory to argue that language inherently pairs form and meaning, a concept dating back to Ferdinand de Saussure in the early 20th century. In contrast, LLMs operate only on “form,” producing language patterns without any grasp of meaning or communicative intent. This lack of understanding, she asserts, makes LLMs akin to “stochastic parrots”—repeating patterns without comprehension.
Risks of Mimicking Language
Bender explains that these systems are fundamentally designed to generate “plausible” text sequences rather than accurate or contextually meaningful information. This distinction becomes especially problematic when LLMs are deployed in roles that require reliable information or understanding, as the systems may confidently produce incorrect or misleading statements.
📉 Persistent Inaccuracies and Misinformation
The Design Limitations of LLMs
The statistical basis of LLMs predisposes them to generate errors, which Bender argues are not merely accidental but rather systemic and inevitable. Since LLMs determine text based on likelihood rather than factual accuracy, they are bound to produce misinformation, especially when asked to extend beyond trained data with unique or niche queries.
Impact on AI-Powered Tools
AI tools embedded in workplace software or consumer applications are particularly susceptible to spreading misinformation. Bender notes that while such tools might produce text that appears accurate, the actual factual integrity of the content requires verification by human users, effectively shifting the burden back to the user and negating the supposed convenience of the tool.
🌐 Data Bias: A Challenge in Large-Scale Models
Inherent Bias in Training Data
Bender emphasizes that there is no truly unbiased training dataset, especially when LLMs are trained on vast amounts of internet data. The internet includes a multitude of harmful biases, from racism and sexism to ideological distortions, which LLMs absorb and reproduce. Bender argues that the lack of transparency around LLM training data further compounds this problem, as users and even developers often lack detailed knowledge of the model’s sources.
Problems with Filtering and Curation
Attempts to filter harmful content from LLM datasets often fall short. Bender notes that early efforts included a list of banned words, many related to sexuality and LGBTQ topics, which unintentionally eliminated valid data while failing to remove problematic content. In her view, LLM development must move toward more thoughtful and curated data selection to minimize harmful biases, but this is challenging under the current trend of indiscriminately expanding data scope.
🔍 LLMs and Search Engines: A Mismatch for Information Retrieval
Contextual Limitations in LLM Search Applications
Bender argues that using LLMs as search tools fundamentally misunderstands how users interact with information. A traditional search engine allows users to see the source and context of results, such as expert articles or user forums. In contrast, LLMs provide synthesized responses detached from their original context, preventing users from assessing credibility or exploring the variety of perspectives that often enrich search results.
Environmental and Social Concerns
Beyond accuracy, Bender raises environmental concerns, noting that the computational demands of LLMs require significant electricity, leading to a substantial carbon footprint. She suggests that the industry must weigh these impacts against the limited benefits that LLMs bring to search and information retrieval.
🧩 Challenges of Machine Translation
Benefits and Risks of AI Translation
While Bender acknowledges that machine translation can break down language barriers, she also cautions against overreliance. Fluent translations can lead users to assume accuracy, but linguistic nuances may be lost, particularly with less common languages. Bender calls for greater transparency about the uncertainty in translation results, emphasizing that machine translation should be used with an awareness of its limitations.
👥 Anthropomorphism and Its Pitfalls
Misleading Terminology
Bender resists terms like “hallucinations” for AI errors, as such words anthropomorphize LLMs by suggesting they have human-like thoughts or intentions. She argues for language that reflects these systems’ actual limitations, urging the use of terms that emphasize functionality over capability, like “error” instead of “hallucination.”
The Problem with “Artificial Intelligence”
Bender critiques the term “artificial intelligence” itself, arguing that it sets up unrealistic expectations. The concept of “intelligence” in AI, she notes, has roots in eugenics, as the history of intelligence as a measurable quality is controversial and ethically fraught. Bender stresses that these systems are computational tools, not intelligent beings, and should be discussed in terms that clarify rather than mystify their functions.
🌐 Homogenization of Language and Ideas
Cultural and Creative Impact
Bender warns that LLMs could have a homogenizing effect on language and ideas, as they inherently average responses based on patterns in data, potentially stifling creativity. While LLMs may limit exposure to diverse thought, Bender hopes that users will seek out genuine human creativity in response to the prevalence of synthetic text.
🔄 A Purpose-Driven AI Development Model
Building AI Based on Stakeholders’ Needs
Bender proposes an approach to AI development that begins with a clear understanding of end-user needs. She argues that if AI systems were developed with a focus on practical utility and accountability, as opposed to scaling LLMs, more effective and ethical solutions would emerge. For example, in cases like the New York City information access system, AI tools should be developed with input from stakeholders, such as renters, landlords, and government officials, to ensure accurate and lawful information dissemination.
🔍 Research Directions Beyond LLM Scaling
Alternative Pathways in AI Research
Bender encourages researchers to pursue approaches beyond LLM scaling. She highlights the importance of models that emphasize semantic understanding, focusing on how words connect to meaning and intention. These alternative research pathways, she argues, are being overlooked in the rush to scale LLMs, yet they may ultimately lead to more reliable and ethically sound AI applications.
🌌 Rejecting the “Superintelligence” Narrative
Critique of AI Doomsayers and Accelerationists
Finally, Bender addresses a recent split in the AI community between those advocating for rapid AI advancement and those fearing its existential risks. She rejects the underlying assumption of both camps that LLMs could lead to artificial general intelligence. Instead, she views the current fascination with superintelligence as misguided, with both sides exaggerating the technology’s potential. Bender warns that focusing on AI “doom” or “acceleration” detracts
