Catching up on a project to review the state of validation studies for a few psychological constructs relevant to my upcoming work.

Send help. Every time I look at the state of measurement in cs and the social sciences it’s a bit terrifying.

It's thanksgiving, which is a great day to revisit classic Americana.

We really need someone to re-make The Music Man for tech policy.

This August as I sheltered indoors from wildfire smoke, I got a moving note from MIT statisticians - my disability story had informed a fundamental insight about wildfire smoke forecasting.

In this post, I describe the scientists who - astonishingly - applied lessons from my disability […]

In the last twenty years of my journey as a scientist and organizer, only three pieces about mathematics have brought me to tears.

In this post, I write about the common thread in each of those pieces and the privilege of seeing that inspiration come full circle […]

If you are a convicted fraud and cheat, you don't heal wounds by trying to take a leadership position in the industry that you cheated.

And having support from a couple of rich people doesn't mean you have support from the people of a sport […]

Has anyone looked into creating a very privacy-protecting service that would help people find out if they appeared in one of these horrific deepfake archives and take action?

Today I am stepping down from my role as the CEO of #mastodon. Though this has been in the works for a while, I can't say I've fully processed how I feel about it. There is a bittersweet part to it, and I think I will miss it, but it also felt necessary. It feels like a goodbye, but it isn't—I […]

Today I submitted my member's vote to sell a nonprofit's building. This 50+ year national organization has inspired and supported so many people over the years, but like many nonprofits, it has really struggled this year.

In class, I asked students to choose one public good that they care […]

Can public involvement in AI evaluation make the science better? Or does it compromise quality, speed, and cost for the sake of politics?

"Remarkably, there is no trace of any rulers, palaces, or elite residences. Unlike later Maya cities, which were built under centralized authority, Aguada Fénix seems to have been a collective project: a monumental achievement born of cooperation rather than coercion."

One joy of growing as a scholar & doer has been the pleasure of being supported to pay attention to other people’s excellent work and amplify it.

Next week I am publishing an article summarizing over 170 articles on an AI + science + policy and tomorrow I get to email their authors to say thanks <3

As someone with a respiratory disability with a partner who has a severe scent sensitivity, I have found it helpful to imagine our home with the analogy of a spaceship.

The first line of defense in our home is this “airlock” where we seal away anything scented […]

Spent the day doing unexpected maintenance after multiple things in my life and my neighborhood broke down. Reminding myself that maintenance is meaningful work, even if unexpected.

Time to get some rest.

When people started proposing “friction” as a response to online problems, I mostly just regarded it as under-theorized. I didn’t really imagine it would become a profit center where companies would charge more to suspected bad actors seeking to advertise […]

How can we know if a law or policy has chilled people’s free expression? Can we use science to find out? And would courts pay attention?
