‘Contextualization Engines’ can fight misinformation without censorship

Search engines are nice. But we can do far better with modern AI. — ‘We are increasingly seeing the weaponization of context,’ — Claire Wardle.

Build Wise Systems: Combining Competence, Alignment, and Robustness

Understanding decision-making systems and what that means for governance, corporations, and technology creators. — This is the first piece in a set of work on ‘Reimagining Technology’; Most of my prior public work focused on misinformation, online platforms, platform/AI governance, and the impacts of AI/ML.

When we change the efficiency of knowledge operations, we change the shape of society.

AI-augmented knowledge summarization, refactoring, & integration are about to transform the world. Again. — Technology creators, funders, and policymakers must understand how changes in knowledge operations can impact society. This is intended to be a short primer making a series of claims about these impacts. Each claim could be a book (many are). 1. Knowledge operations matter. Knowledge operations are ‘actions that involve the conveying or processing of…

Platforms Are Still Flying Blind When It Comes to Societal Impact — Better Metrics Could Help

Metrics are key to how product teams at tech companies function — After the 2020 election, a Twitter dashboard that I first prototyped four years before started going wild. It estimates misinformation prevalence by monitoring “the percent of retweets and likes pointing toward domains that had made a habit of sharing misinformation.” This metric had been going up throughout the election cycle…

The Path to Deepfake Harm

How, when, and why synthetic media can be used for harm — This is post is an excerpted section from a working paper with Jess Whittlestone (shared in 2019, but minimal updates were needed). While the full paper was focused on synthetic media research, this section is far more broadly applicable and often referenced in other contexts—it applies in general to malicious…

Making Sense of Deepfake Mitigations

How can we fortify our “Knowledge Pipeline” in the face of synthetic media? — Close to two years ago, I started applying the framework described below in order explore ways to reduce the negative impacts of synthetic media (and other forms of misinformation).

What does a world with automated social engineering look like?

And how should that change the way we approach security and disclosure? — The technology now exists to create tools for gathering public information on people and spear-phishing them — automatically, at scale. Or creating a system that uses calls with forged realistic voices to impersonate someone. These new attack capabilities are being made possible by modern AI and may have significant implications…
