Welcome – and thank you for visiting Psycholo.ge.
This site is something I’ve wanted to build for a long time: a dedicated space where psychometrics, research methodology, and the psychology of the digital world come together. After years of working in educational assessment and teaching at the university level, I felt it was time to create a professional home for my work – a place where research, tools, and ideas could live together and be accessible to anyone who shares these interests.
Who I Am
My name is Giorgi Tchumburidze. I’m an Associate Professor of Psychology and the head of the Psychology in the Digital World program at BTU (Business and Technology University) in Tbilisi, Georgia. Before joining BTU, I spent years working as a researcher at the National Assessment and Examinations Center (NAEC), where I was directly involved in Georgia’s participation in international large-scale assessments – PISA, PIRLS, and TIMSS.
That experience shaped how I think about measurement, data, and what numbers can (and can’t) tell us about human behavior.
What You’ll Find Here
Psycholo.ge is organized around three pillars:
Research – I’m currently working on several projects: examining the psychological predictors of academic achievement using PISA data, validating widely-used psychological scales (PSS-10, General Self-Efficacy) for Georgian populations, investigating the digital divide among Georgian students, and an interdisciplinary project analyzing Shota Rustaveli’s “The Knight in the Panther’s Skin” through the psychological framework of William James. You can explore all of these on the Research page.
Tools — I believe that statistical methods should be accessible, interactive, and visual. That’s why I built the Statistical Concepts Explorer (SCE) — an open-source R Shiny application with 65 interactive modules covering everything from descriptive statistics to Item Response Theory. Alongside SCE, you’ll find PsychoMetrica, a Georgian-language IPIP-60 Big Five personality assessment, and a Codebook Generator. All tools are free and available on the Tools page.
Blog – This is where I’ll share tutorials, research notes, and thoughts on the field. Expect content on R programming for psychometrics, statistical concepts explained visually, behind-the-scenes notes from ongoing research, and reflections on how digital technology is reshaping psychology and education. I’ll write in both English and Georgian, depending on the audience.
Why “The Science of Human Behavior, Measured”?
Psychometrics sits at the heart of everything I do. It’s the discipline that asks: how do we quantify something as complex as human cognition, personality, or motivation? How do we build instruments that are reliable, valid, and fair across cultures and languages?
These aren’t just technical questions – they have real consequences for students, policies, and societies. When Georgia participates in PISA, those measurements influence educational policy. When we validate a stress scale in Georgian, we’re making mental health research possible in our language. The tagline is a reminder of what’s at stake: the measurement matters.
What’s Next
In the coming weeks, you can expect:
- An in-depth walkthrough of the Statistical Concepts Explorer
- R tutorials on psychometric analysis
- Research notes from my ongoing PISA Georgia study
- Reflections on teaching psychology in the digital age
If you’re a researcher, student, educator, or anyone curious about the science behind psychological measurement – this space is for you.
Feel free to explore the site, try out the tools, and reach out through the Contact page. I’d love to hear from you.
