Better judgment under uncertainty

I write and build, across more fields than a business card can hold — machine learning, autonomy, product, the psychology of a swipe, why a front-heavy Honda Civic oversteers. What pulls me in is always the same thing: someone, or something, running on a bad model of reality. I like to poke at it, work out how to test it, and build a better one. A few of those attempts are below.

How I got here

This site started with an irritation. I'd read yet another news article that misunderstood and misrepresented a scientific study — a small, everyday failure of judgment dressed up as reporting and optimized for web traffic. Writing became the way I work these problems out: how to read evidence, how to weigh tradeoffs, how to tell a real signal from a flattering one.

The same question follows me away from the keyboard. I like to go in circles — there is something clarifying about endless laps on a running track or a race track, anywhere from 15 km/h to 150, where stray thoughts get drowned out in a flow state. Then I get to analyze the data endlessly afterwards, which I also did as a day job for many years: turning messy, high-stakes situations into something measurable.

The racing was no accident either. When I turned 25 I bought a sports car and took it to a track, where I met some awesome people with the same obsession. Things escalated. We ended up running a race team for a few years, before I moved to the UK, where I reside now.
