The Invisible Gorilla experiment is a well-known psychological study from 1999, and highlights our cognitive biases and the limitations of our attention.
This now-classic research project has shown that selective attention has implications for various aspects of our lives, from decision-making to personal safety.
In the next 4 minutes, you will explore the Invisible Gorilla experiment, the phenomena of selective attention and inattentional blindness, and examples of inattentional blindness in real-life scenarios.
Also, I will mention the consequences of inattentional blindness and hopefully provide helpful ways to deal with its effects.
The Invisible Gorilla experiment
In the late 1990s, psychologists Daniel Simons and Christopher Chabris conducted an experiment in which they instructed participants to watch a video of two groups of people passing a basketball.
Participants were instructed to count the number of passes made by one team while ignoring the other team’s passes. An easy task that requires some amount of focus.
However, the video included a small surprise.
While the people were throwing the ball at one another, a person wearing a gorilla suit walked through the scene, stopped in the middle, pounded their chest, and then walked off.
That’s too crazy to be ignored, right?
Well, the researchers found that despite the gorilla’s prominent appearance in the video, around 50% of the participants did not notice it.
This phenomenon is known as inattentional blindness and occurs when an individual is so focused on a particular task or stimulus that they overlook other unexpected stimuli in their environment.
That was the Invisible Gorilla experiment, which is now considered a classic one in the field of human behavior.
Selective attention: What does the Invisible Gorilla experiment teach us?
The Invisible Gorilla experiment teaches us that human attention is selective and limited.
We cannot process all the information presented to us at once, so we must selectively attend to specific stimuli while filtering out others. That allows us to focus on essential tasks but can also cause us to overlook unexpected or potentially critical events.
Inattentional blindness is not a sign of incompetence or lack of intelligence. It instead highlights the inherent limitations of human attention.
Understanding this phenomenon can help us become more aware of our cognitive blind spots and develop solutions to mitigate their harmful effects.
The police pursuit example
One real-life example that illustrates the consequences of selective attention and inattentional blindness is a 1995 police pursuit incident.
During a high-speed chase, police officer Michael Cox chased a suspect on foot while other officers arrived at the scene. The arriving officers mistakenly believed Cox was a suspect and began assaulting him.
At the same time, another officer, Kenny Conley, continued pursuing the same suspect on foot and ran past the altercation without noticing it.
Conley was later convicted of perjury and obstruction of justice, as he claimed not to have seen the assault.
Researchers Christopher Chabris and Daniel Simons conducted a study to test the plausibility of Conley’s claim.
During their experiment, participants jogged behind an assistant, counting the number of times the assistant touched their hat.
While jogging, the participants passed a staged fight.
The results showed that more than 40% of the participants missed the fight in broad daylight, and 65% missed it at night.
This experiment showcased that Conley’s claim was plausible, proving the powerful effects of inattentional blindness.
The radiologist experiment
Another example that highlights the implications of the Invisible Gorilla experiment in professional contexts involved radiologists.
In a study conducted by psychological scientists Trafton Drew, Melissa Vo, and Jeremy Wolfe, 24 experienced radiologists were asked to examine CT scans of patients’ lungs, searching for nodules that could indicate lung cancer.
However, in a set of scans, the researchers inserted a small image of a gorilla into the lung scan.
Despite the gorilla being 48 times larger than a typical nodule, 83% of the radiologists failed to notice the gorilla while focusing on identifying the cancerous nodules.
This study shows that even highly trained professionals are susceptible to inattentional blindness when their attention is focused on a specific task.
How can inattentional blindness hurt us?
Selective attention can significantly help us when we need to focus on a specific task for a given period, but leading to inattentional blindness can also hurt us in different ways:
- Decision-making: Focusing on a single aspect of a complex decision can lead to neglecting other essential factors, resulting in mediocre outcomes.
- Work performance: Selective attention can cause critical mistakes in tasks that require different skills to deal with a specific problem.
- Personal safety: In high-stress situations or while multitasking, we may overlook potential hazards, increasing the risk of accidents or injury.
- Interpersonal relationships: Selective attention can prevent us from understanding others’ perspectives or empathizing with their emotions, leading to miscommunication and conflict.
7 ways to deal with inattentional blindness
Selective attention is a natural cognitive process, but we need to find ways to mitigate the potential negative consequences of its by-product, inattentional blindness.
Here are 7 ways to deal with inattentional blindness:
1. Increasing awareness
Recognize that your attention has limitations and that you may miss things even when you believe you are paying close attention.
2. Practicing mindfulness
By trying out mindfulness exercises, you can better understand what your mind is focused on and, in that way, enhance focus and self-awareness in the long term.
3. Breaking tasks into smaller parts
By dividing tasks into smaller, more manageable pieces, you can allocate attention more effectively and, as a result, reduce the chances of overlooking critical details.
4. Taking breaks
Taking breaks is equally important as doing focused work. Regular breaks can prevent mental fatigue, which can exacerbate inattentional blindness.
5. Collaborating with others
We all have flaws and different qualities as human beings. That’s why working in teams can help compensate for individual attentional limitations; different perspectives increase the likelihood of identifying critical information.
6. Limiting distractions
Create an environment that minimizes external distractions, allowing you to focus more effectively on the task at hand.
7. Prioritizing tasks
Rank tasks by importance and allocate your attention accordingly to ensure you address the most critical aspects first.
Conclusion
The Invisible Gorilla experiment is a reminder of the limitations of our attention as human beings.
By understanding how selective attention and inattentional blindness work, we can become more aware of our cognitive biases and work to counteract any possible adverse outcomes.
Also, if we can find ways to enhance our focus while addressing the effects of inattentional blindness, we can enjoy better decision-making, improved work performance, increased personal safety, and more effective interpersonal communication.
The ultimate purpose is to acknowledge, on the one hand, the limits of our attention and, on the other hand, to address them whenever possible.
In that way, we can navigate the complexities of the modern world more effectively and purposefully.

Frequently Asked Questions (FAQs)
What is the Invisible Gorilla experiment, and what does it reveal about human attention?
The Invisible Gorilla experiment, conducted by psychologists Daniel Simons and Christopher Chabris, demonstrates the concept of inattentional blindness, where people can miss obvious things in their visual field when their attention is focused elsewhere. This experiment reveals that human attention is selective and has its limitations, showing that we cannot process all the information in our environment simultaneously.
How does selective attention impact our daily lives?
Selective attention impacts our daily lives by allowing us to focus on specific tasks or stimuli, filtering out irrelevant information. While this helps us concentrate and perform tasks efficiently, it can also lead us to overlook important or unexpected events, affecting decision-making, work performance, personal safety, and interpersonal relationships.
Can inattentional blindness be considered a flaw in human cognition?
Inattentional blindness is not necessarily a flaw in human cognition but rather a byproduct of the way our attention mechanisms are designed. It highlights the inherent limitations of our attentional focus, showing that while we can concentrate on certain aspects of our environment, this concentration can cause us to miss other, potentially significant information.
How can inattentional blindness affect professional performance?
Inattentional blindness can affect professional performance by leading to critical mistakes, especially in tasks requiring comprehensive attention to detail. For instance, healthcare professionals may overlook anomalies in diagnostic images, or law enforcement officers might miss crucial evidence during investigations, demonstrating the need for strategies to mitigate these effects.
What strategies can help mitigate the effects of inattentional blindness?
Strategies to mitigate inattentional blindness include increasing awareness of attentional limitations, practicing mindfulness to enhance focus, breaking tasks into smaller parts, taking regular breaks to prevent mental fatigue, collaborating with others to benefit from diverse perspectives, limiting distractions, and prioritizing tasks to allocate attention effectively.
Why is understanding the Invisible Gorilla experiment important?
Understanding the Invisible Gorilla experiment is important because it sheds light on the selective nature of human attention and the phenomenon of inattentional blindness. By recognizing these aspects of human cognition, we can develop better strategies for managing our attention, improving our decision-making processes, enhancing work performance, ensuring personal safety, and fostering more effective communication in interpersonal relationships.
What role does mindfulness play in combating inattentional blindness?
Mindfulness plays a significant role in combating inattentional blindness by increasing self-awareness and the ability to notice present-moment experiences without judgment. By practicing mindfulness, individuals can improve their focus, become more aware of their surroundings, and potentially reduce the instances of missing important stimuli due to focused attention elsewhere.
How can teamwork help in reducing the effects of inattentional blindness?
Teamwork can help reduce the effects of inattentional blindness by bringing together diverse perspectives and compensating for individual attentional limitations. Working in a team allows for multiple sets of eyes and ears to observe different aspects of a situation, increasing the likelihood of identifying critical information that might be missed by an individual working alone.
