Decoding a Footballer’s Brain: Decision-making Amidst Chaos

Football player analyzing his next move on the field.

A staggering 2,500 thoughts or reactions dart through a footballer’s brain during a 90-minute match. But what does this data reveal about their decision-making processes on the pitch? As an avid follower of the game, I’ve always been intrigued by how these athletes make split-second choices. By diving deep into the sea of cognitive science, let’s unravel the enigma of decision-making amidst the chaos of football.

Understanding Decision-making in Football

Football is an unpredictable sport. Coaches and trainers invest hours perfecting game details, but success isn’t guaranteed. Yet, this unpredictability is perhaps the sport’s allure. Quoting Van Gaal: “A pass from A to B isn’t just that pass; a human is behind it. That individual is influenced by the mind.” Let’s delve deeper into how thoughts influence decision-making and understand the dynamics during chaotic moments on the field.

Perception and Interpretation

Every thought that crosses our mind originates from sensory information. While our senses capture a multitude of data, our brain processes only a fraction of it. Studies have indicated that less than 10% of what our eyes capture is consciously processed. Interestingly, our brain sometimes skews this information. Take the Hermann-grid for instance. Observing it, you’ll notice white dots turning black due to high contrast. This phenomenon demonstrates how our brains manipulate our perceptions.

The Power of Thoughts

Ever wondered about the origin of the changing dots in the Hermann-grid experiment? Surprisingly, humans have around 40,000 distinct thoughts daily. These vary from basic needs like hunger to intricate game decisions like passing the ball. These thoughts predominantly dictate our actions, with most of them operating subconsciously. According to Professor Kahneman, this subconscious decision-making is labeled as System 1, which often operates seamlessly without effort, like gauging someone’s mood. In contrast, System 2, our conscious thought process, handles intricate tasks like solving complicated math problems or establishing complex connections. Most decisions made during a game are subconscious. For example, take a look at Dolberg’s goal here.

His movements and coordination, honed through extensive training, are instinctively directed by System 1, allowing for quick reflex actions.

Reacting at the Speed of Thought

How is it that players like Dolberg can decide so swiftly? Kahneman’s System 1 processes over eleven million bits per second, in stark contrast to System 2, which handles just 45 bits. Reaction speed is vital. In labs, participants can differentiate between ‘new’ and ‘seen’ images in 300 milliseconds, activating System 2. Meanwhile, in response to an unexpected stimulus, a human can make an eye movement in just 100 milliseconds, three times faster than usual, showcasing System 1’s prowess. Researcher Chris van der Togt offers an insightful perspective: “Most actions are unconscious executions of pre-automated patterns. For instance, in martial arts, confident fighters react quickly, but in doubt, they slow down as they think more. Conscious decisions can be remarkably slow. Ever watched a child choosing between banana and chocolate ice cream?”


A footballer’s brain is a marvel. The intricate interplay of conscious and subconscious thoughts dictates their actions on the field. As spectators, we get a front-row seat to this remarkable display of cognitive prowess, wrapped up in the unpredictability and charm of the game.
