How to think the unthinkable: weak signals, extreme futures, and foresight (with Mehdi Nemri)

In the world of intelligence and strategy, everything starts with a simple mission: see what others don’t. We collect data. We track weak signals. We build scenarios. And sometimes, we DARE to anticipate the unexpected.

How to think the unthinkable: weak signals, extreme futures, and foresight (with Mehdi Nemri)

How do you distinguish the signal from the noise?

I have had the honor of interviewing Mehdi Nemri: a brilliant mathematician and futurist.

His field? Mapping future scenarios, modeling extremes scenarios, and making the invisible... legible.

This is not a typical conversation, it's also a long one that requires a bit of focus. So I suggest you take a cup of coffee or tea, you sit, and take the time to read and "digest" this interview.


Who is Mehdi Nemri - in his own words?

I've been practicing prospective analysis since 2013, with a pause in teaching. I'd describe myself as a practitioner of anticipation, encompassing consulting for organizations, extensive research - which increasingly constitutes a large portion of my work - and training. Collectively, these activities define my professional role.

However, fundamentally, I consider myself more of a theorist.

A mathematician deeply engaged with long-term issues, dedicated to developing mathematical methods and tools to better understand potential future developments. The term 'prospective practitioner' can sometimes seem vague; thus, my path has led me to identify primarily as a mathematician and theorist.
