Thinking is changing shape.

We study human cognition in AI-mediated knowledge work: what happens to attention, judgment, authorship and self-worth when the systems people work with can produce fluent work on demand.

Featured publication

How one experienced user interrupts AI, and why the most fluent output is the hardest to question.

Interruptive Thinking: An Empirical Study of Operator-Side Control in AI Interaction

People who work with large language models routinely stop the model and redirect it. This autoethnographic study codes 611 such interruptions from 29 of the author's own working sessions, and describes a six-stage interruption cycle along with where the data does not fit it.

Three findings follow. The three AI models used to code the sessions disagree substantially about what counts as an interruption. User actions are described with 172 different labels, yet six recur far more than the rest. And the moments that most needed an interruption were often those where the model's output was most fluent.

Research

AI is no longer a tool people use. It is part of the environment they think in.

The questions that interest us are not mainly about whether these systems make people faster. They are about what thinking becomes when a capable system is always present in it.

Attention, interruption and control

When and how people stop, redirect and constrain AI systems mid-task, and what prompts them to.

Agency, authorship and self-worth

How people judge their own competence, and what they count as theirs, when AI contributes materially to the work.

Reliance and judgment

How people decide when to trust AI output, and why fluent, well-organised output is a poor guide to whether it should be trusted.

Sensemaking and reflection

How people turn fragments into understanding, notice patterns and revise their beliefs when an AI is part of the process.

Personal cognitive infrastructure

The notes, chats, memory systems and assistants people build around themselves to think, remember and resume unfinished work.

Methods for studying AI-mediated work

How to observe, record and code human-AI interaction reliably, including the limits of using AI models as qualitative coders.

How we work

Four commitments we hold our own work to.

Open data

Data behind a published claim is released openly, with a script that reproduces the numbers we report.

Report the misfits

Our first paper reports that 29 of 47 receipts contained an interruption its model does not fit cleanly. Misfits are findings.

Disclose AI use

When AI systems help code data or draft text, the paper says so, and every number is checked against the source.

State the limits

Our first study draws on one user's sessions. We say so plainly, and design the next studies to go beyond it.
