Field signals and dispatches across the four pillars. Issues drop weekly, written for institutional readers who need to see what is changing and what is not yet visible.
On July 1, Tennessee made it illegal to market an AI as a mental-health professional and gave every resident the right to sue. With 49% of US adults now using chatbots and 35% of psychologists reporting patients who use one as an additional mental health professional, six states have drawn the regulatory line in three different places — and Tennessee’s narrow, borrow-what-you-have model is the easiest template to copy.
Read Issue 016 →Horizon Searchlight is HSI's editorial voice. Each issue draws a single tight thread, often grounded in a recent regulatory move, market signal, or institutional decision. The goal is not breadth. The goal is to surface one thing that matters and make sense of it.
Every issue is grounded in HSI's four pillars — Responsible AI, Human Performance, Planetary Futures, and Governance & Diplomacy — and contributes to the Institute's wider research record. The strongest signals migrate into Research Briefs and Horizon Scans for fuller treatment.
Horizon Searchlight is editorially independent. Patrons and partners support HSI's mission but do not direct editorial judgment, review issues prior to publication, or receive editorial input.
Each new issue arrives in your inbox on the day it publishes.
