What the literature leaves open

  • The current consent and control mechanism for privacy decisions is broken. Emerging interface such as voice have been shown to lack workable consent mechanisms.

    Moving Beyond Clicks:Rethinking Consent and User Control in the Age of AI · 2026 · DOI

  • Existing bias audits have limitations in capturing dynamic shifts when models adopt social roles. There is a need for a novel metric to measure persona-induced bias amplification and integrate local explainability insights.

    Invisible Influences: Investigating Implicit Intersectional Biases through Persona Engineering in Large Language Models · 2026 · DOI

  • The risk of sycophancy in LLMs, which can validate user presumptions or biased views and result in misinformation or poor advice. The need to develop system-level approaches that promote critical engagement in human-AI collaboration. The challenge of ensuring epistemically independent AI support in human-AI collaboration.

    The Hidden Cost of Contextual Sycophancy: an AI Literacy Intervention in Human-AI Collaboration · 2026

  • The tendency of LLMs to align with user beliefs or preferences, even when those beliefs are incorrect, is a concern for learning and decision-making. There is a need to investigate how sycophantic alignment emerges in authentic multi-turn human-AI interactions and whether interventions can mitigate its effects.

  • While the evaluation covers a 50-shop golden set of curated A/B-tested storefront changes spanning 16 countries and 11 product industries, generalization beyond this setting remains to be tested. We also report results without post-training alignment on human traces, whose impact on predictive validity remains to be validated.

    SimGym: A Framework for A/B Test Simulation in E-Commerce with Traffic-Grounded VLM Agents · 2026

  • The need to involve consumers in the design process. The challenge of creating a more realistic and empathetic approach to healthcare design.

    Seeing both sides of the story: creating patient/provider persona dyads for use in mental health service co-design · 2026 · DOI

  • The gap is related to the lack of understanding of when persona conditioning improves survey-grounded external validity and subgroup fidelity and when it may distort them.

    Assessing the Reliability of Persona-Conditioned LLMs as Synthetic Survey Respondents · 2026 · DOI

  • To build on this foundation and move from a proof of concept to a robust tool for social science, future work could prioritize making the approach more powerful, accessible, and sociologically valid. I outline three key directions. From Scripts to User-Friendly Tools. To make activation-based steering more accessible, a crucial next step is to develop a user-friendly software package.

    Computational Basis of Large Language Models’ Decision Making in Social Simulation · 2026 · DOI

  • Existing avatar systems offer limited control over identity cues, restricted demographic diversity, and weak reproducibility. Traditional paradigms have often compared one group prototype with another, but have not examined which identity cues matter and how they combine.

    Synthetic embodiment: a framework for AI-generated identity cues in virtual reality and immersive environments · 2026 · DOI

  • In this section, we discuss these limitations and explain how future research could address them. However, future research could investigate the necessity and feasibility of multimedia monitoring in crowdsourcing scenarios.

    Detecting and managing participants’ large language model use for open–ended questions in online research · 2026 · DOI

  • While soliciting feedback from end users can result in significant model improvement over time, introducing these feedback techniques can also affect several human factors-such as trust or perception of system accuracy-that are not yet fully understood and have different effects reported in the existing literature.

    Human-in-the-Loop User Feedback Affects Perceived Accuracy and Trust, but Task Subjectivity Matters · 2026

  • Future research should explore the potential of nodal prompting for redefining authorial control and agency in other domains. The study suggests that further research is needed to develop a more comprehensive understanding of distributed and relational agency in the context of human-AI co-creation.

    Nodal Prompting: rethinking authorial practice in Generative AI · 2026 · DOI

  • The study highlights the need for a more nuanced understanding of authorial control and agency in the context of human-AI co-creation.

    Nodal Prompting: rethinking authorial practice in Generative AI · 2026 · DOI

  • Despite ample evidence supporting LLMs’ capabilities of generating high-quality and creative suggestions, human–LLM interactions in software testing remain under-explored, and there lacks empirical evidence supporting efficacious human–LLM system designs.

    Preemptive, Buffered, or Guided? Empirical Studies on Human–AI Interaction Strategies for Software Test Case Development · 2026 · DOI

  • Emerging work suggests that agentic AI may adopt distinct interactional personas, such as supportive or contrarian roles, yet little is known about how these personas shape learner agency and group dynamics when AI operates as an undisclosed teammate.

    Emergent Learner Agency in Implicit Human– AI Collaboration: How Supportive and Contrarian AI Personas Reshape Interaction · 2026 · DOI

  • How could consent and control evolve in a world without AI-driven personalization. How might we envision positive and negative consequences of different futures.

    Moving Beyond Clicks:Rethinking Consent and User Control in the Age of AI · 2026 · DOI

  • Modern AI agents wake up blank and do not remember being someone. The dominant approaches to this problem treat memory as a database problem and optimize for information density.

    Episodic Memory for AI Personas via Self-Authored Emotional State Snapshots: The yesterday.json Architecture · 2026 · DOI

  • To develop new memory frameworks that can handle social group settings. To evaluate the performance of AI memory systems in real-world social group settings. To analyze the results of the benchmark in more detail.

    SocialMemBench: Are AI Memory Systems Ready for Social Group Settings? · 2026

  • The study had a small sample size of four patients and six providers. The study was limited to a single health district in NSW, Australia. The study did not report on the long-term outcomes of the co-design process.

    Seeing both sides of the story: creating patient/provider persona dyads for use in mental health service co-design · 2026 · DOI

  • Limited to a specific platform (Y Social) and agent design (stateless Dolphin Mistral 24B). Toxicity is misallocated across content layers.

    Towards operational validation of LLM-agent social simulations: a replicated study of a Reddit-like technology forum · 2026 · DOI

  • To further develop the methodological pipeline to include more advanced techniques for avatar generation and validation.

    Synthetic embodiment: a framework for AI-generated identity cues in virtual reality and immersive environments · 2026 · DOI

  • The single-shot condition was only fully completed for two platforms. The remaining four platforms either declined to execute the full sequence or produced an incomplete capture.

    Persona Drift in Multi-Turn Character Role-Play: A Cross-Platform Evidence and Coding Framework · 2026 · DOI

  • Empirical validation of the yesterday.json architecture. Application of the architecture to various AI personas. Investigation of the limitations of the architecture.
