Why Our Brains Struggle with Habits – And What Science Just Discovered

Have you ever wondered why some habits stick so easily while others feel nearly impossible to break? Why does scrolling your phone late at night come so naturally, but building a consistent study routine feels like climbing a mountain?

A fascinating 2025 study from the Sainsbury Wellcome Centre at University College London gives us new answers. Scientists discovered that the brain doesn’t rely on just one learning system—it actually uses two different “tracks” of learning.

Track 1: The “Value-Based” System

This is the system most of us are familiar with. It’s all about weighing choices, predicting rewards, and learning from experience. For example:

• You try a new café. If the coffee tastes great, your brain remembers that positive reward and motivates you to go back.

• If it’s terrible, you avoid it next time.

This system is flexible and logical. It helps us adapt to new situations and make smarter decisions.

Track 2: The “Habit System”

Here’s where things get interesting. The researchers found another system—called APE (Action Prediction Error)—that learns in a different way. Instead of weighing value or rewards, this track is about repetition and automatic response.

Think about brushing your teeth. You don’t calculate the “value” every time—you just do it, because repetition has wired it into your brain. The same is true for bad habits: once the brain’s APE system locks in a repeated action, it becomes automatic, even if it’s not helpful.

Why This Matters for Daily Life

This dual-track discovery explains why habits can feel so stubborn. Even if your logical brain knows scrolling Instagram at 1 a.m. ruins your sleep, the habit system doesn’t care—it just follows repetition. That’s why willpower alone isn’t enough.

The good news? Because science now understands these two tracks, it shows us that:

• To break bad habits, we need to interrupt the automatic loop and replace it with healthier actions.

• To build good habits, we should focus on repetition and consistency, not just motivation.

Where Time Management Comes In

Most people think of time management as a planner or a to-do list. But in reality, it’s about training your brain’s two learning systems to work for you, not against you. When you set routines, review your progress, and reset after setbacks, you’re actually reprogramming both your value-based system and your habit system.

That’s why structured approaches to time management are so powerful. They don’t just make you “more productive”—they help you rewire the brain so that focus, discipline, and follow-through become second nature.

Science shows that we’re not just “lazy” or “unmotivated” when habits feel hard to change—our brains are literally running on two tracks at once. But with the right strategies, you can align those tracks and make lasting change.

If you’ve ever struggled with routines, procrastination, or time slipping away, this is exactly what we dive into in our new Time Management program. Think of it as brain-friendly training that helps you master not just your schedule, but your habits—and, ultimately, your life.
