Navigating Reproducibility Challenges in Human-Computer Interaction Research with Large Language Models

Core Concepts

The increasing adoption of Large Language Models (LLMs) in Human-Computer Interaction (HCI) research poses new challenges for ensuring reproducibility, which must be carefully navigated to maintain the credibility and validity of HCI findings.

Abstract

This article explores the impact of Large Language Models (LLMs) on reproducibility in Human-Computer Interaction (HCI) research. It highlights several key issues that the HCI community must address: Learning from Past Reproducibility Challenges: The article draws parallels between p-hacking in quantitative research and the potential for "prompt hacking" when using LLMs. It emphasizes the need to proactively address these new reproducibility pitfalls, rather than repeating past mistakes. Bias Across User Experience Research: LLMs can amplify existing biases in HCI research by reflecting the perspectives and experiences of the limited data used in their training. The article suggests strategies to mitigate this, such as using multiple diverse LLMs and critically examining the interplay between LLM biases and human subject data. LLMs for Cross-Validation and Analysis Support: While LLMs present opportunities to support data analysis and validation across HCI's diverse research methods, the article cautions against over-reliance on LLMs, which could introduce new reproducibility issues. Defining New Reporting Requirements and Educating the Community: The article proposes establishing clear documentation requirements for LLM usage in HCI research, providing educational resources for the community, and incentivizing the development of transparent and accessible LLMs. Addressing the Risk of Increased Research Pressure: The article acknowledges the potential for LLMs to increase publication pressure, which could lead to premature adoption and suboptimal practices. It suggests managing expectations, quickly developing and communicating best practices, and educating peer reviewers to mitigate these risks. Overall, the article advocates for a comprehensive and proactive approach to addressing reproducibility challenges posed by the increasing use of LLMs in HCI research, with the goal of maintaining the credibility and validity of HCI findings.

Quotes

"By using LLMs, we might make UCD cheaper and hence more widely applicable; at the same time, though, we put pressure on the field to move this way to stay competitive. Hence, the transparency about how UCD is conducted and to what extent models are used is critical."

How can the HCI community collaborate with LLM developers to ensure the transparency of training data and model biases?

In order to ensure transparency regarding training data and model biases in Large Language Models (LLMs) used in Human-Computer Interaction (HCI) research, collaboration between the HCI community and LLM developers is crucial. One way to achieve this is through establishing open communication channels between researchers and developers. HCI researchers can engage with LLM developers to gain insights into the training data sources, methodologies, and potential biases inherent in the models. By fostering a collaborative relationship, researchers can work towards understanding and mitigating biases present in LLMs. Additionally, the HCI community can advocate for increased transparency standards from LLM developers. This can involve requesting detailed documentation on the training data used, the processes involved in model development, and the mechanisms in place to address biases. By encouraging developers to provide this information, researchers can make more informed decisions about the use of LLMs in their studies and ensure that potential biases are acknowledged and accounted for. Furthermore, collaborative efforts can focus on developing tools and frameworks that facilitate the assessment of model biases and the transparency of training data. By working together, the HCI community and LLM developers can create resources that enable researchers to evaluate the reliability and validity of LLM outputs, thereby enhancing the reproducibility and credibility of HCI studies involving LLMs.

How might the integration of LLMs into HCI research workflows impact the overall research ecosystem, including funding, career trajectories, and the role of human participants?

The integration of Large Language Models (LLMs) into Human-Computer Interaction (HCI) research workflows has the potential to significantly impact the overall research ecosystem in various ways: Funding: The adoption of LLMs in HCI research may lead to changes in funding priorities. Funding agencies and organizations may allocate resources towards projects that leverage LLMs for data analysis, design support, and user interaction simulations. Researchers who incorporate LLMs into their work may have access to additional funding opportunities specifically tailored to AI-driven HCI research. Career Trajectories: The use of LLMs in HCI studies could influence career trajectories within the research community. Researchers with expertise in AI and natural language processing may be in high demand for HCI projects that utilize LLMs. Additionally, individuals who specialize in the ethical implications of AI technologies may find new career paths in evaluating the impact of LLM integration on HCI research practices. Role of Human Participants: The role of human participants in HCI studies may evolve with the integration of LLMs. Researchers may explore the substitution of human participants with LLMs for certain tasks, such as ideation support or data analysis. This shift could raise ethical considerations regarding the treatment of human subjects and the validity of results obtained through LLM-human interaction simulations. Overall, the integration of LLMs into HCI research workflows has the potential to reshape funding priorities, influence career trajectories, and redefine the role of human participants in research studies, prompting the research community to adapt to the changing landscape of AI-driven HCI research.

What novel research methods or validation techniques could be developed to address the unique reproducibility challenges posed by the use of LLMs in HCI studies?

Addressing the unique reproducibility challenges posed by the use of Large Language Models (LLMs) in Human-Computer Interaction (HCI) studies requires the development of novel research methods and validation techniques tailored to the characteristics of LLMs. Some innovative approaches that could be explored include: Prompt Protocol Standardization: Establishing standardized protocols for generating prompts when interacting with LLMs can enhance reproducibility. Researchers can define specific guidelines for prompt construction, ensuring consistency in inputs and reducing the risk of prompt-hacking biases. Bias Detection Algorithms: Developing algorithms that can detect and quantify biases in LLM outputs can aid in assessing the reliability of results. By analyzing the language patterns and semantic structures of LLM-generated content, researchers can identify and mitigate potential biases introduced during the training phase. Human-LMM Hybrid Validation: Implementing validation techniques that combine human judgment with LLM outputs can enhance the credibility of research findings. By involving human reviewers to assess the accuracy and relevance of LLM-generated content, researchers can validate results and address hallucination risks. Version Control and Model Repository: Creating version control mechanisms and centralized repositories for LLM models used in HCI studies can improve reproducibility. Researchers can track model versions, parameters, and training data sources, enabling the replication of experiments and the verification of results across different versions of LLMs. Cross-Validation Frameworks: Establishing frameworks that facilitate cross-validation of LLM outputs through multiple models or validation techniques can enhance result reliability. By comparing outputs from different LLMs or validation methods, researchers can identify inconsistencies and ensure the robustness of findings. By exploring these novel research methods and validation techniques, the HCI community can address the reproducibility challenges associated with LLMs, fostering transparency, reliability, and validity in AI-driven HCI research practices.
