Critical Thinking Collapse 2.0: AI’s Impact on OSINT
AI isn’t just speeding up OSINT - it’s reshaping what investigators and leaders believe is true. As hallucinations, data poisoning, and AI-generated narratives flood the information space, critical thinking is collapsing inside intelligence cycles. This blog exposes how AI-shaped distortions already influence investigations, threat intelligence, and decision-making and what must be done to stop the next intelligence failure.

OSINT is Still a Thinking Game
I’ve been thinking a lot about why conversations around OSINT feel increasingly shallow, even though the tools we use have never been more powerful. We have more data, automation, dashboards and AI-generated summaries than at any point in the history of intelligence. And yet, when I look at how conclusions are drawn, how confidence is expressed, and how often assumptions go unchallenged, I can’t escape a deeply uncomfortable feeling: We are collecting more than ever and thin

The Next Five Years of OSINT: Trends Innovations and Challenges Transforming Investigative Landscapes
Open-source intelligence (OSINT) is entering its most disruptive era yet. What was once a clear, open landscape is splintering into disappearing data, platform restrictions, AI-driven deception, and geopolitical pressure that reshapes information in real time. OSINT is no longer just about collecting data, it’s about surviving a shifting environment that will redefine how investigators work in the next five years.

OSINT - Cities with hundreds of names | How OSINT investigators miss hidden clues
You think you know Amsterdam? You don’t. Even if you’re born and raised there. For OSINT investigators, analysts, and journalists, searching only for “Amsterdam” means missing half the signal. The city hides behind slang, symbols, codes, and multilingual aliases. This post shows how language masks location, why alias awareness matters, and how Boolean and regex uncover Amsterdam’s hidden digital footprint across the open web, social media, and the dark web.

What OSINT Really Is - And Why AI Keeps Getting It Wrong
OSINT isn’t about collecting public data, AI already does that better than humans. OSINT is about pressure-testing reality. In digital investigations, organisational security, and business risk, OSINT turns fragmented public signals into defensible understanding. As AI increases visibility but not judgment, OSINT remains a human discipline: questioning sources, timelines, intent, and absence. This article breaks down what OSINT really is, how it’s used, why businesses rely on

Exploring the Role of OSINT in Intelligence Work and Law Enforcement Training
OSINT intelligence from publicly available sources has become essential in modern investigations. When paired with HUMINT, it strengthens threat detection, verification, and operational planning. Together, they offer deeper insight, improved accuracy, and faster decision-making, making OSINT training vital for today’s law enforcement and intelligence professionals.

THE KIDS AREN’T ALRIGHT - AND THE INTERNET KNOWS IT
A 13-year-old boy sat gaming after school while someone he’d never met groomed him in a private chat. His mother sensed the shift only when his humour sharpened, his tone hardened, and his words echoed patterns seen in the AIVD’s 2025 report. This wasn’t curiosity, it was reshaping. And it’s not rare anymore. Across the world, children are being radicalised entirely online, often before adults notice.

Black Swans in OSINT: Why We Keep Missing the Impossible
The biggest threat in OSINT isn’t lack of data. It’s ego.
The moment you think you understand the dataset, you stop learning from it.
The moment you think you can’t be surprised, you stop being useful.
Black Swans don’t hide, they just look irrelevant until they change everything.
Your dashboard doesn’t need more data.
It needs more doubt.

The Slow Collapse of Critical Thinking in OSINT due to AI
This isn’t a rant against AI. I use it daily, ChatGPT, Copilot, Claude, Gemini. They’re in my workflow like everyone else’s. But the tradecraft is slipping. Analysts are skipping the hard parts. They’re trusting GenAI to do the heavy cognitive lifting, and it’s changing how we operate at a foundational level.
