Navigate through my background, research, and current projects
From property law to web development to productivity research
I’m Jonathan Griffin - productivity researcher and writer. I write science-backed articles on attention, focus, and cognitive productivity that bridge neuroscience research with practical application.
My journey here has been unconventional:
Today, I synthesize insights from neuroscience, behavioral psychology, and decades of cognitive science research. Every article includes citations, peer-reviewed studies, and practical frameworks you can implement immediately.
The driving question behind all my work:
“How do we align our daily workflow with how the brain actually functions?”
This isn’t about productivity hacks or time management tricks. It’s about understanding the fundamental cognitive mechanisms that drive effective work and building systems around those principles.
What I'm building and writing to help you work better
I’m actively developing multiple projects to bridge the gap between cognitive science and practical productivity:
Focus Timer Application
Long-Form Research Articles
Web Applications for Productivity
Comprehensive Productivity Science Book (early development)
The goal across all projects: make cognitive science research accessible and actionable for knowledge workers who want to work with their brains, not against them.
How I approach productivity science and why it matters
Productivity advice has become too prescriptive and one-size-fits-all. My approach is fundamentally different:
Evidence Over Anecdotes - Every technique I write about is grounded in peer-reviewed research from cognitive science, neuroscience, and behavioral psychology. Personal experience informs application, but science drives the foundation.
Systems Over Quick Fixes - Rather than productivity hacks, I focus on understanding the underlying cognitive mechanisms that drive focus and attention. Once you understand how the brain works, you can build lasting systems rather than chasing the latest technique.
Flexibility Over Dogma - The brain is complex and individual. What works depends on your chronotype, cognitive style, work context, and personal constraints. My goal is to give you frameworks that adapt to your reality.
Practical Implementation - While I love diving deep into research, every article includes actionable insights you can implement immediately. Science without application is just interesting trivia.
My legal background taught me to demand evidence and question assumptions. My technical background showed me how to build scalable systems. Now I apply both to help you work with your brain’s natural patterns instead of fighting against them.
This isn’t about working harder or longer - it’s about working in alignment with how attention and focus actually function.
How to reach out, collaborate, or reference my work
I’m always interested in connecting with researchers, professionals, and readers who share a passion for evidence-based productivity.
Reach out if you:
For citations and references: All articles include complete reference lists with peer-reviewed sources. I continuously update research as new studies emerge, so check article dates for the most current findings.
Response commitment: I read every email personally and respond within one week. For collaboration inquiries or detailed research questions, I may take longer to provide thoughtful responses.
The best conversations come from people who are applying these concepts in real work environments and can share what they’re discovering in practice.
