📌 Heuristic Anchoring Bias in LLMs Summary
Heuristic anchoring bias in large language models (LLMs) refers to the tendency of these models to rely too heavily on the first piece of information they receive when generating responses. This bias can influence the accuracy and relevance of their outputs, especially if the initial prompt or context skews the model’s interpretation. As a result, LLMs may repeat or emphasise early details, even when later information suggests a different or more accurate answer.
🙋🏻♂️ Explain Heuristic Anchoring Bias in LLMs Simply
Imagine you are taking a quiz and the first clue you get makes you think of a certain answer, so you keep sticking with that idea, even if later clues suggest something else. LLMs can behave the same way, sticking to the first suggestion or information given even when it is not the most accurate.
📅 How Can it be used?
Designing chatbot prompts to reduce anchoring bias can improve the reliability of automated customer support responses.
🗺️ Real World Examples
A medical chatbot using an LLM may give advice heavily influenced by the first symptoms a user mentions, potentially missing a correct diagnosis if additional, more relevant symptoms are added later in the conversation.
In financial advice platforms, an LLM might anchor on the initial investment amount mentioned by a user and base all recommendations on that figure, even if the user later updates their financial situation or goals.
✅ FAQ
What is heuristic anchoring bias in large language models?
Heuristic anchoring bias is when a language model pays too much attention to the first bit of information it receives. This means if the first part of a prompt is misleading or incomplete, the model might stick with that idea and not fully adjust its response, even if better information comes later.
How can heuristic anchoring bias affect the answers given by language models?
This bias can cause language models to repeat or focus on early details in a conversation, even if more accurate or relevant information shows up later. It can make answers less accurate because the model may not update its response with new facts or context as it should.
Can I do anything to reduce heuristic anchoring bias when using language models?
You can help by giving clear, complete information right from the start. Try to avoid leading with details that might send the model in the wrong direction. If you need to add extra information later, it can help to restate the main points so the model has a better chance to update its answer.

Uncertainty-Aware Models
Uncertainty-aware models are computer models designed to estimate not only their predictions but also how confident they are in those predictions. This means the model can communicate when it is unsure about its results. Such models are useful in situations where making a wrong decision could be costly or risky, as they help users understand the level of trust they should place in the model's output.
AI for Civic Engagement
AI for Civic Engagement refers to the use of artificial intelligence to help citizens interact with their governments and communities more easily. It can simplify processes like finding local information, participating in discussions, or reporting issues. By automating tasks and analysing public feedback, AI helps make civic participation more accessible and efficient for everyone.
Token Validation
Token validation is the process of checking whether a digital token, often used for authentication or authorisation, is genuine and has not expired. This process ensures that only users with valid tokens can access protected resources or services. Token validation can involve verifying the signature, checking expiry times, and confirming that the token was issued by a trusted authority.
Prompt Archive
A Prompt Archive is a digital collection or repository where prompts, or instructions used to guide artificial intelligence models, are stored and organised. These prompts can be examples, templates, or well-crafted queries that have proven effective for certain tasks. By maintaining a prompt archive, users can reuse, adapt, and share prompts to get consistent and reliable results from AI systems.
Session Volume
Session volume refers to the total number of individual sessions recorded within a specific period on a website, app or digital service. Each session represents a single visit by a user, starting when they arrive and ending after a period of inactivity or when they leave. Tracking session volume helps businesses understand how often people are using their platforms and can highlight trends over time.
