Long-form analysis on global risk, foreign policy, and the institutions doing the work.
Foresight by Meridian is the publication where Meridian’s arguments get worked out in full — with sources, with evidence, with the reasoning visible.
Foresight publishes long-form analytical essays on global risk, foreign policy, public health, the institutional architecture of the post-1945 order, and the conditions under which that architecture either holds or comes apart. The audience is anyone who wants the argument with the evidence attached, not just the conclusion. The cadence is weekly. The voice is institutional. The standard is rigor.
Each piece sits at the intersection of at least two domains Meridian works in — epidemiology and policy, security studies and constitutional law, capital markets and global risk — because the problems Meridian cares about almost never sit in a single discipline. The format is built for that. Long enough to do the work. Short enough to read in one sitting.
Foresight is published on Substack and is free to read. A paid subscription tier is in development; the writing will remain free for readers who want it that way.
The published archive is below, in reverse chronological order. Each piece is hosted on Substack and freely accessible. Click any title to read the full essay.
New essays land in your inbox as they publish. The writing is free; the only cost is your email. A paid tier is in development and will give subscribers early access to longer pieces and bonus material — but the core writing will always remain free.
