Do you think that your attention is under siege? Are overflowing inboxes and relentless ping of notifications disturbing you? Focus On-Off by Mark Tigchelaar and Oscar de Bos arrives as a timely guide. The book dives deep into the science of attention, revealing how our brains process the 11 million bits of information bombarding us every second and why we often feel overwhelmed. Tigchelaar, a neuropsychologist, and de Bos, founder of Focus Academy, combine cutting-edge research with practical “life hacks” to help people reclaim their focus and productivity.

I wrote previously another post inspired by the book of Johann Hari’s Stolen Focus on the same topic but this book focuses on different aspects. A comparison may be useful to get a wider perspective.

The Neuroscience of Focus: Four “Concentration Leaks”

The authors identify four key “concentration leaks” that disrupt our ability to focus:

1. External distractions (notifications, open tabs, noisy environments)
2. Internal distractions (worries, mind-wandering, emotional triggers)
3. Task-switching overload (the cognitive cost of jumping between tasks)
4. Lack of recovery (failing to give the brain downtime)

These leaks are backed by recent studies. For example, research from National Geographic and MIT’s Attention Lab confirms that task-switching can reduce productivity by up to 40% and increase error rates by 37%, a stark reminder that “multitasking” is often just rapid task-switching in disguise.

Some Myths About Attention

1. Myth: Concentrating is hard.
   • Reality: Our brains are wired to prioritize information efficiently. The issue isn’t our ability to focus, but the sheer volume of stimuli competing for our attention. Tigchelaar and de Bos argue that focus is a skill that can be trained, not just a fixed trait.
2. Myth: Turn off notifications to focus.
   • Reality: While notifications are disruptive, the deeper problem is our brain’s reward system, which craves novelty. The authors suggest “strategic distraction” breaks, short, planned pauses to reset attention rather than just silencing alerts.
3. Myth: We should all be ‘time-blocking.’
   • Reality: Rigid scheduling can backfire. The book advocates for “focus rhythms”, aligning work with natural peaks in alertness (e.g., mornings for deep work, afternoons for lighter tasks).
4. Myth: We can’t beat Big Tech.
   • Reality: While tech is designed to hook us, studies show that mindful usage like setting app limits or using “loose attention” for creative tasks can mitigate its pull. The authors provide a step-by-step guide to reducing screen time without feeling deprived.

Practical Tips from Focus On-Off

• The Surprising Benefits of Fidgeting: Movement (doodling, pacing) can boost focus by engaging the brain’s motor cortex, reducing mental fatigue.
• Multi-Switching vs. Multi-Tasking: The book distinguishes between harmful task-switching (e.g., emailing while in a meeting) and beneficial multi-switching (e.g., alternating between related tasks to maintain engagement).
• Inbox Zero: A clear email strategy, batch processing, filters, and the “2-minute rule” (a strategy that suggests if a task can be completed in two minutes or less you should do it immediately to avoid procrastination and increase productivity) can cut through digital clutter.
• Targeted vs. Loose Attention: Know when to hyperfocus (e.g., writing a report) and when to let your mind wander (e.g., brainstorming).

The Science of Screen Time and Social Media

Recent research underscores the book’s warnings: excessive screen time is linked to concentration difficulties, and social media multitasking correlates with poorer performance. Yet, the authors avoid alarmism, offering tools like “digital detox” routines and “attention audits” to help people assess their habits.

Why This Book Stands Out

Unlike generic productivity guides, Focus On-Off grounds its advice in neuroscience and real-world testing. The authors’ backgrounds, Tigchelaar’s work with athletes and entrepreneurs, de Bos’s Focus Academy, lend credibility to their methods. The book’s accessibility (short chapters, actionable exercises) makes it a standout in a crowded field.

Final Thoughts: A Manual for the Distracted Age

Focus On-Off is more than a productivity book; it’s a manual for thriving in an era of distraction. By blending science, storytelling, and practical tools, Tigchelaar and de Bos empower readers to take control of their attention without guilt or gimmicks.
