Spot the Gorilla: Inattentional Blindness in Workplace Safety

Ever hear the one about a gorilla, a banana and a construction site? No, itโ€™s not the start of a bad joke… but it might be a great way to talk about hazard awareness at work. Before we dive in, let’s talk about the phenomenon of inattentional blindness.

Inattentional blindness is the tendency to overlook unexpected objects or events because our attention is focused elsewhere. Itโ€™s that moment when youโ€™re so locked into a task that you completely miss what’s right in front of you.

A classic example is the viral video where people were asked to count basketball passes. Half way through, a person in a gorilla suit casually walks through the scene. In the initial experiment, fifty percent of people were busy watching the ball, they missed the big furry guy entirely.

Donโ€™t believe me? Watch this video and see how you go.

You probably saw the gorilla this time. Thatโ€™s because you knew to look for it. But did you catch the other changes?

This experiment by Dan Simons and Christopher Chabris is a perfect example of how we can miss the unexpected when weโ€™re focused on something else. And these ‘invisible gorillas’ donโ€™t just show up in psychology experimentsโ€”they can show up anywhereโ€”even in the workplace.

Are There Gorillas in Your Workplace?

In the world of safety, these โ€˜gorillasโ€™ represent the hazards and risks we overlook. And because we donโ€™t notice them, we donโ€™t manage them. Theyโ€™re the slippery patches, unguarded equipment, or that one toolbox always sticking out where it shouldnโ€™t be. We donโ€™t see them because weโ€™re either too focused on our work, or our attention is pulled elsewhere. And the scariest part? The more experienced we are at a task, the more likely we are to miss those gorillas.

Itโ€™s like when youโ€™ve driven the same route to work for years, and suddenly realise you donโ€™t remember half of the journey because your brainโ€™s on autopilot. Our attention works the same way when it comes to spotting hazards. The things we donโ€™t expect to seeโ€”or havenโ€™t trained ourselves to look out forโ€”can go totally unnoticed.

It’s Not Just Blindnessโ€”Itโ€™s Deafness, Numbness, and Even Smell

Turns out, inattentional blind spots go beyond what we see. Thereโ€™s inattentional deafness (yep, not hearing that beeping alarm), numbness (missing out on those vibrations that signal machinery isn’t running right), and even anosmia (not catching a funky smell that signals a potential problem). So, weโ€™re not just missing the gorillaโ€”we might be missing all the sounds, touches, and smells that are trying to wave red flags too!

How to Make Those Gorillas Stand Out

So, how do we make sure our teamโ€™s not missing gorillas in the workplace? Here are some practical tips to improve hazard recognition and give inattentional blindness the boot:

  1. Change Your Perspective, Literally
    Sometimes, our routines cause us to overlook risks. Challenge your team to switch things upโ€”whether itโ€™s entering the job site from a different direction or observing a task from a new vantage point. This small shift can highlight hidden hazards and encourage a broader awareness of the environment.
  2. Gorilla Hunts
    Before starting any task, take a deliberate moment to scan for potential risks. This isnโ€™t just a quick glance, but an intentional โ€œsafety sweepโ€ to identify anything out of place. Encourage team members to take a moment to step back, look around, and ask themselves, โ€œWhatโ€™s the gorilla in the room?โ€. This brief reset can help bring hidden hazards to the surface.
  3. Engage All Senses
    Donโ€™t just rely on what you can seeโ€”train your team to engage all their senses. Strange sounds, unusual smells, vibrations, or even a subtle change in the environment can signal a potential issue. Encourage your team to tap into these cues as part of their hazard recognition process.
  4. Visual Cues
    Strategically placed visual cues can be powerful reminders. If you want to mix it up, you could even incorporate the gorilla themeโ€”literally! Place gorilla stickers or signs in hazard-prone areas as a playful yet effective reminder for your team to keep an eye out for โ€œhiddenโ€ risks. These visual cues add an extra layer of engagement, helping everyone stay alert to the unexpected.
  5. Routine Check-ins
    Routine safety check-ins are essential, but asking a simple, open-ended question like โ€œWhat might we be missing here?โ€ can take them to the next level. This approach encourages your team to think beyond the usual hazards and consider risks that may not be immediately obvious. By regularly challenging your team to look with fresh eyes and a “beginner’s mindset,” you create a culture of proactive hazard recognition.

Ready to Spot the Gorillas?

Next time youโ€™re out on site, take a moment to really look. Are there any hazards youโ€™ve been walking right past? Any gorillas quietly munching away away while everyoneโ€™s focused on something else?

Inattentional blindness can make even the most obvious risks disappear from view, but by sharpening your teamโ€™s awareness and encouraging fresh perspectives, you can ensure those hazards are caught before they escalate. The goal is simple: to make hazard spotting second nature, so no riskโ€”big or smallโ€”slips through the crack
