Prompting Large Language Models With the Socratic Method

The Socratic Method and Its Application

Chang's paper revolves around the Socratic method, a technique rooted in critical thinking and inquiry through dialogue. The paper identifies and adapts various Socratic techniques such as definition, elenchus, dialectic, maieutics, generalization, induction, and counterfactual reasoning. These techniques are ingeniously applied to improve interactions with GPT-3, aiming to produce more accurate, concise, and creative outputs.

Critical Thinking: The Art of Socratic Questioning

Paul and Elder's work on Socratic questioning categorizes it into three types: spontaneous, exploratory, and focused. These types enhance critical thinking and can be applied effectively in dialogue with large language models.

Spontaneous Questioning

Spontaneous questions arise naturally during a conversation. They are not pre-planned and are often reactive to the dialogue's flow. For example, when a language model provides an unexpected answer, a spontaneous question might be, "What led you to this conclusion?"

Exploratory Questioning

Exploratory questions delve deeper into a subject, exploring the reasons and evidence behind a claim. They are integral to understanding and critically evaluating responses. An example of an exploratory question might be, "Can you explain how you derived this theory from the given data?"

Focused Questioning

Focused questions are targeted and specific, often seeking to clarify a particular point or assumption. They help in narrowing down broad discussions to specific aspects. An example could be, "What are the key factors that support your argument in this specific context?"

These types of questioning, when applied to interactions with language models, can significantly enhance the depth and quality of the dialogue, leading to more insightful and reliable outcomes.

Integrating Socratic Methods with Large Language Models

The application of Socratic methods to LLMs like GPT-4 can significantly enhance their ability to process and interpret complex inquiries. Here's how some of these methods can be applied:

Elenchus (Socratic Refutation)

• Description: Challenging assumptions or logic through questioning.
• Application in LLM: Used to test the language model's reasoning for consistency and accuracy.

Maieutics (Socratic Midwifery)

• Description: Guiding to 'give birth' to new ideas through probing questions.
• Application in LLM: Guides LLMs to explore and elucidate complex topics thoroughly.

Dialectic Method

• Description: Structured dialogue to explore philosophical questions.
• Application in LLM: Engages LLMs in discussions requiring synthesis of opposing ideas.

Inductive Reasoning

• Description: Drawing general conclusions from specific examples.
• Application in LLM: Helps LLMs generalize from specific data points to broader insights.

Definitional Inquiry

• Description: Clarifying concepts by exploring their definitions.
• Application in LLM: Ensures shared understanding of key terms between the model and the user.

Hypothetical Reasoning

• Description: Using hypothetical scenarios to explore ideas.
• Application in LLM: Challenges LLMs to consider consequences of actions or ideas.

Counterfactual Reasoning

• Description: Considering alternative scenarios and their implications.
• Application in LLM: Explores different decisions or events in conversations with LLMs.

Ad Hominem Challenge

• Description: Questioning the source of an argument for biases.
• Application in LLM: Examines the sources of information used by LLMs in constructing responses.

These Socratic techniques, when applied to interactions with LLMs, can enhance the depth and quality of dialogue, leading to more insightful and reliable outcomes.

Understanding Prompt Template Engineering in LLMs

Prompt template engineering is crucial for optimizing LLM interactions. The process varies depending on several factors:

• Left-to-right vs Masked LLMs: For generative tasks, prefix prompts align better with left-to-right LLMs. Conversely, cloze prompts are more suitable for masked LLMs as they resemble the pre-training format of these models.
• Manual vs Automatic Design: Initially, manual design of prompt templates is beneficial. However, for capturing the nuances of input-output dependencies, automatic mining and paraphrasing are recommended.
• Discrete vs Continuous Prompts: Discrete prompts provide fixed input choices, while continuous prompts allow dynamic, conversational interactions, often leading to more creative and tailored responses.

Advanced Prompt Techniques

• Ensemble Methods: Combining basic templates to ask the same question in various ways enhances response diversity and accuracy.
• Explanation-Based Prompting: This method, like the chain-of-thought approach, generates a sequence of explanations before reaching a conclusion. However, this method can be inconsistent, especially in complex or simple tasks like math problems.
• Improving Consistency: Recent developments involve using diverse reasoning paths and majority voting to enhance the consistency and coherence of responses.

Application of the Socratic Method

The Socratic method, integrating deductive, inductive, and abductive reasoning, ensures consistency and accuracy in LLM inferences. It involves critical thinking aspects like definition clarification and cross-examination, greatly enhancing output quality.

Continuous Prompts for Creative and Generative Tasks

The goal is to design continuous prompts that enhance response quality and foster creativity in tasks like information verification, source credibility evaluation, and generating task-specific surprises. This involves selecting the most relevant strategies from the Socratic method, categorized into spontaneous, exploratory, and focused questioning.

Exploring the Depths of the Socratic Method

The Socratic method, more than just a teaching tool, is an exploratory process that fosters critical thinking and self-discovery through a series of strategic questions. Key principles and guidelines of this method include:

• Posing Open-ended Questions: Initiating dialogue with questions that stimulate thinking and draw out ideas.
• Clarifying Key Terms: Ensuring all participants have a shared understanding of important concepts.
• Providing Examples and Evidence: Encouraging the use of concrete examples to support claims.
• Challenging Reason-to-Conclusion Argument: Promoting critical examination of one's own beliefs and considering alternative viewpoints.
• Summarizing and Drawing Conclusions: Assisting in deriving coherent conclusions from discussions.
• Reflecting on the Process: Evaluating the effectiveness and learning outcomes of the method.

Socratic Methods in Detail

1. Definition: Clarifying meanings of terms for deeper understanding.
2. Generalization: Drawing broad principles from observed patterns.
3. Induction: Forming hypotheses based on empirical evidence, albeit with uncertainty.
4. Elenchus: Testing hypotheses' consistency through cross-examination.
5. Hypothesis Elimination: Disproving false hypotheses with counterexamples and logic.
6. Maieutics: Facilitating self-discovery and innovation through reflective questioning.
7. Dialectic: Exploring opposing views to deepen understanding.
8. Recollection: Belief in innate knowledge, accessible through questioning.
9. Irony: Using irony to highlight ignorance and misunderstandings.
10. Analogy: Employing comparisons to grasp complex ideas.

Application in Critical and Creative Thinking

• For critical thinking tasks, methods like definition, elenchus, dialectic, hypothesis elimination, and generalization are particularly effective.
• In creative thinking or brainstorming stages, techniques like maieutics, induction, and counterfactual thinking come to the forefront.

Adapting to Language Models

• Techniques like analogy, irony, and recollection are less relevant due to language models' limitations in understanding figurative language and memory constraints.
• The focus is on methods that can be effectively utilized within the context window of language models, enhancing their ability to recall and process information.

Implementing the Socratic Method in Critical Reading: The CRIT Template

One of the paper's significant contributions is the development of CRIT (Critical Reading Inquisitive Template). CRIT evaluates documents and produces a validation score by analyzing claims and their supporting reasons. This tool demonstrates the practical application of the Socratic method in a language model context, particularly for tasks involving critical reading and analysis.

CRIT's Socratic Approach

CRIT uses various Socratic methods in its implementation:

1. Method of Definition: Identifying the conclusion of a document and ensuring clear understanding.
2. Method of Elenchus: Cross-examining the arguments for consistency and coherence.
3. Method of Dialectic: Generating and evaluating counterarguments to avoid one-sided perspectives.
4. Method of Maieutics: Facilitating self-discovery and understanding rather than directly imparting knowledge.
5. Counterfactual Reasoning: Imagining alternative scenarios to deepen understanding of the topic.

Practical Application of CRIT

• Definition Method: CRIT starts by asking GPT-3 to identify the conclusion of a document, using clear instructions and definitions.
• Elenchus Method: It involves evaluating the validity of each reason supporting the conclusion and cross-examining the arguments.
• Dialectic Method: CRIT prompts GPT-3 to provide counterarguments, ensuring a balanced evaluation.
• Maieutics Method: Once CRIT has scored the text, it prompts GPT-3 to summarize and analyze the arguments, fostering analytical skills.
• Counterfactual Reasoning: In the final step, CRIT encourages considering the arguments based on new contextual information.

Critical and Creative Thinking in CRIT

CRIT incorporates Socratic methods suited for critical and creative thinking, such as induction for brainstorming, hypothesis elimination, and generalization for deriving broader principles. The choice between submitting prompts all at once or one-by-one can affect the depth of analysis, with one-by-one prompting preferred for teaching critical reading due to its detailed engagement.

Pilot Studies and Observations

The paper presents a pilot study that validates the effectiveness of CRIT in enhancing the output quality of language models. It also provides valuable insights into the best practices for prompt submission, whether sequentially or all together, depending on the document's length and complexity.

Conclusion

Edward Y. Chang's paper is a testament to the potential of combining classical critical thinking strategies with modern language models. By applying the Socratic method, Chang opens new avenues for enhancing the interaction with and output of language models. This approach not only improves the accuracy and relevance of the models' responses but also fosters creativity and critical thinking, which are invaluable in various applications, from academic research to creative writing.

Future Prospects

The paper concludes with promising avenues for future research, suggesting that the methodologies developed could be further refined and applied across different domains. The integration of the Socratic method and language models holds immense potential, and its exploration is just beginning.
