Understanding the Distinction Between the Two Modes of Thinking

In 2013, while preparing for my macroeconomics exam at Goethe University in Frankfurt, I frequently encountered challenges that felt overwhelming. The anxiety of tackling problem sets, such as analyzing short-run outcomes in a fixed-price economy during a foreign economic crisis, was palpable.

I spent countless hours at the university library, intensely focused on the task at hand. I was surrounded by piles of calculations and economic models, yet the solution seemed elusive, akin to hitting a brick wall from every possible angle.

Eventually, I decided to take a break and strolled through Grüneburgpark. The soothing sounds of rustling leaves and distant conversations gradually eased my tension. As I meandered, allowing my mind to wander, a previously unnoticed idea from a past lecture resurfaced, connecting seamlessly to the challenge I had been grappling with. It was like a bolt of lightning — a potential solution materialized. But how did this happen during a break?

At that time, I didn't realize that the diffuse mode was working wonders in the background. Upon returning to my studies, I approached the problem with newfound clarity, and the solution appeared much more attainable.

Focused Mode: Delving Deep into a Subject

The focused mode of thinking is what we typically associate with dedicated effort. It's the mindset we adopt when deeply engaged in a task, whether it involves solving a complicated problem or acquiring a new skill.

This mode activates the prefrontal cortex, the brain's region responsible for attention, short-term memory, decision-making, and task execution. While studying or practicing something new, the focused mode enables your brain to immerse itself in the subject, absorb fresh information, and carry out specific tasks. This mode is critical for deliberate practice, a fundamental component of skill enhancement and effective learning.

Diffuse Mode: Fostering Creativity and Connections

Conversely, the diffuse mode represents a more relaxed state of mind. It operates independently of specific brain regions, allowing for spontaneous and subconscious connections. This mode emphasizes broad thinking and neural connections over depth.

When you're not actively concentrating on a task—such as when you're taking a walk, daydreaming, or even sleeping—your brain naturally transitions into the diffuse mode. This state can spark creative ideas and help you connect disparate concepts, leading to innovative solutions or better questions.

The idea of these two modes may first have been identified by Edward de Bono, although he did not delve into their evolutionary backgrounds. Other studies have linked the roles of the left and right hemispheres of the brain to balancing awareness and focused tasks. Barbara Oakley may have been the first to tie this concept specifically to the emergence of these two thinking modes.

Combining Both Modes for Optimal Learning

The secret to effective learning lies in the interplay between focused and diffuse modes of thinking. The focused mode enables you to absorb and practice new material, while the diffuse mode aids in forming creative links and mental models. The trick is to consciously alternate between these modes instead of trying to use them simultaneously or solely prioritizing the focused mode.

Avoid the pitfall of continuous focus, which can lead to tunnel vision and impede your problem-solving capabilities. Instead, allow yourself time to step back, detach from the immediate task, and let your brain process information subconsciously in the diffuse mode.

Here are a couple of strategies to integrate this practice:

1. Pomodoro Technique: Utilize a Pomodoro timer to work in focused mode for 25 minutes, followed by a 5 to 10-minute break for diffuse thinking. Repeat this cycle to maintain productivity while allowing your brain to recharge.
2. Push to the Edge: When tackling a problem, stay in focused mode until you encounter confusion. Then, intentionally switch to the diffuse mode by engaging in an unrelated activity, such as taking a phone-free walk. Experiment with different triggers to enter diffuse thinking; activities like showers, walks, meditation, or yoga can help you relax and access this mode, enabling your brain to form new connections.
3. Sleep on It: Work on challenging material just before bedtime. Your brain will continue processing the information during sleep, and you may awaken with fresh insights.

Final Thoughts

Next time you find yourself struggling with a problem, remember to utilize both focused and diffuse modes of thinking for improved learning and problem-solving.

Here are three actionable strategies to implement:

• Apply the Pomodoro technique to enhance focus while allowing your brain to recharge.
• Remain in focused mode until you reach a standstill, then switch to diffuse mode, perhaps by aimlessly wandering in a park to enable your brain to make new connections.
• Address a problem right before going to sleep so your brain can continue working on it overnight.

By strategically integrating these thinking modes, you can unlock the potential for optimal learning and more effective problem-solving.
