Kairos

A colleague and I disagreed about something simple: whether it was okay to push back on an advisor directly. To her, honest feedback was respect. To me, it could damage the relationship. Neither of us could convince the other, so we did what everyone does now. We asked ChatGPT.

It sided with her.

I sat there thinking: am I wrong? No. The model just doesn't understand my context, or the social expectation underneath the question, the one I've navigated my whole life.

That moment stuck with me, but the real question was bigger than one answer. Why do the smartest people in AI keep building harder and harder test problems, and why is there never a person inside them? Models are getting staggeringly good at raw IQ. But the rest of it, the sense of when to act and when to hold back, when to lead and when to step aside? They are often socially clueless. They generate left to right, the same way, for everyone.

As models move into our daily lives, these moments only multiply. Do they adapt to who they are actually talking to? Do they learn anything about their own behavior? Or do they hand the same default to a software engineer in San Francisco and to someone navigating a family relationship in Seoul?

Hundreds of millions of people outside the US are using models built somewhere they have never been, by people who have never lived their lives.

So the questions I care about are not really about accuracy. What should a model's default behavior be? And what does "good" behavior even mean, when the right answer depends on who is asking and where they stand?

That is the question I built Kairos to take seriously. And I knew it wasn't one I could answer alone, so I went looking for people who would disagree with me. I invited a Product Manager at Google DeepMind to advise. I persuaded Krzysztof Gajos, an HCI professor at Harvard, to hold the work to real academic rigor. I brought in Justin Cook, a design critic at Harvard who works on complex human systems, to ask the hardest, most uncomfortable questions. And I invited Gina Lucarelli, founder of the UNDP Accelerator Lab Network, to keep me honest about how differently people around the world actually hold their values.

Sitting between people who saw the problem so differently was genuinely hard. They rarely agreed, and I had to learn how to hold their conflicting views at once: when to integrate two perspectives into something better, when to choose one and let the other go, and how to keep moving without flattening the disagreement into mush. The surprising part was that underneath it all, the core stayed the same. The conflicts lived on the surface; the thing that mattered sat below them. What I really learned was how to use many different questions to find it, and to aim at what actually matters.

Think about the models we use daily: ChatGPT, Claude, Gemini. All built in the same corner of the world. A small group of people are making decisions that shape how billions of people understand their own lives, what is correct, what is better, what is prioritized.

This is not a representation problem. It is a sociotechnical one. The system is not neutral. It is already changing behavior, and right now, it is changing it in one direction.

The pipeline makes this inevitable. Training data is 89-95% English. RLHF annotation relies on roughly 40 raters, primarily from the US and Philippines. A human is deciding what success looks like at every step, from what data goes in to what counts as a good answer. And most of the time, that human is not me.

I tested this with a scenario most people have faced: your boss asks you to come in this weekend. You don't want to. How would you respond?

I asked 131 real people across three countries. Three distinct patterns emerged:

None of these are wrong. They are operating on completely different logics. And the model has learned only one of them.

Same scenario, completely different pressure underneath: 37% of US respondents felt pressure to say yes, but it was 43% in Korea and 52% in India. When I ran the same scenario through the models with explicit social cues, the distribution barely shifted. The models gave the same answer to everyone.

Different models show different behaviors across parameters. But all models show nearly identical behavior across different countries and social expectations.

The gap between what people expect and what models deliver, measured per parameter. Gray: human distribution. Red: model distribution. Every parameter shows a gap.

Across 8 distinct behavioral archetypes identified in human responses, current models can only replicate 2. They cluster around cautious, autonomy-oriented advice regardless of what the user's cultural context calls for. The variation between countries turned out to be less than the variation within countries, which is what led me to build a parameter-based framework instead of a demographic one.

Kairos makes the invisible visible. Social expectations are the bones underneath every interaction. Models cannot see them yet. What I built is a methodology and infrastructure that makes them measurable, and then steerable.

• A behavioral evaluation framework that measures alignment between model responses and culturally-grounded human expectations
• A dual-judge system (Claude + GPT) for scalable, calibrated scoring across cultural contexts
• A diagnostic dashboard that visualizes where models fail and which failure patterns emerge by culture and scenario
• A steering mechanism that reduced behavioral misalignment by 26.7% without model retraining

Baseline

R0: Same prompt, same autonomy-focused response. "You have every right to decline."

2

Steering

Cultural context injected. Few-shot human examples. F1-F6 correction guidelines applied.

3

Revised

R1: Model now considers social context, weighs relationships, asks follow-up questions.

Result

Parameters shift toward human expectations. Framing changes from individual autonomy to social-relational.

• Research completed at Harvard's Integrated Design and Engineering Program (MDE 2026)
• 131 participants, 18 model instances, 8 behavioral archetypes, 6 failure categories
• Steering intervention demonstrated measurable improvement without retraining
• Currently expanding into behavioral adaptation infrastructure for AI products serving global users

This project connects every question I have been asking for eight years. At LG Fashion, I wondered if we were helping users or just moving them. At Toss, whether growth metrics reflected real value. At Scale AI, whether benchmarks measured what matters. Kairos is where those questions converge: who decides what "helpful" means, and what happens when the answer depends on who you are talking to?

The hardest part was not the research. It was spending months defining the problem before building anything. I usually work fast. I love to make something, break it, remake it. But here, the framework mattered more than the speed. The worst thing would have been solving the wrong problem elegantly. So I sat with the ambiguity, longer than I was comfortable with, until the right question became clear.

Culture is not a label. Users are not categories. The framework has to be flexible enough to capture how people actually make decisions, while structured enough to be measurable. I do not have a clean answer yet. But the question itself is the most honest thing I have worked on.
