Welcome to Blue Cognition People Analytics Blog
Data Has Always Been About People
For over two decades I’ve worked in HR — hiring, developing, and retaining talent across industries and countries. And throughout that journey, one thing has become clear: the best HR decisions aren’t made by gut feeling alone.
Data changes how we see people — not as numbers, but as patterns. Patterns of engagement, of attrition risk, of what makes a team thrive or fall apart. When used thoughtfully, analytics doesn’t dehumanize HR. It makes it more precise, more fair, and more impactful.
What This Blog Is About
Blue Cognition is my consulting practice. This blog is where I think out loud — combining my years of HR experience with the data science skills I’ve been building.
You’ll find:
- 📊 Analyses — real datasets, R code, and insights on workforce topics
- 🧠 Deep dives — organizational behavior, talent strategy, culture
- 🤖 AI & HR — practical applications of machine learning in people management
- 🛠️ Tutorials — how to do people analytics in R, step by step
Why R?
R is my tool of choice. It’s the language of data science in academia and increasingly in business analytics. Combined with Quarto, I can write posts that are fully reproducible — you can run the code yourself and see exactly how I got there.
