Chapter 1: The Illusion of Reality

We've all seen the iconic film The Matrix, right? If you haven't, it's definitely worth a watch. The central theme revolves around the protagonist discovering that the world he perceives isn’t genuine but rather an elaborate illusion.

What if this scenario holds true in our everyday lives? What if we were informed that we can't fully rely on our brains to accurately interpret the sensory data we receive? The unsettling reality is that we can't.

The Matrix, crafted by the Wachowski siblings, is significant not just for its storyline but also for a groundbreaking filming technique it introduced—“bullet time.” One of the first instances occurs when Trinity (played by Carrie-Anne Moss) defies gravity to kick an assailant in a hotel. For a fleeting moment, she appears to hover in mid-air, bending the rules of physics before the camera performs a full 360-degree spin around her, capturing every detail in sharp focus.

When it premiered in 1999, audiences had never experienced anything like it. Although similar effects can be traced back to Japanese anime, the term “bullet time” gained popularity primarily due to its application in The Matrix.

Since then, this technique has been utilized in various contexts, from cinematic moments to fast-food advertisements. Advancements in camera technology have made it easier to achieve the effect now, but back in 1999, it involved a complex setup. Over 100 still cameras were arranged in a circle around the scene, with actors suspended on wires, and CGI was used to recreate the background on green screens. Each still camera captured images simultaneously, creating a unique perspective.

However, stitching those images together wouldn’t yield a smooth scene. The mesmerizing effect was enhanced through “motion interpolation,” a process that generates the missing frames.

What relevance does this have to our cognitive processes? Just as the filmmakers employed still cameras to capture various angles and artificial techniques to fill in the gaps, our brains constantly patch up the voids in our perceptions.

In neuroscience, this phenomenon is referred to as saccadic masking. Our perception of reality is a blend of external stimuli and what our brains anticipate should be there.

If you glance around your current environment—be it home, a café, or a busy street—it all feels quite convincing. However, with every eye movement, there's a brief lapse in vision, and our brains employ a method akin to “bullet time” to create a seamless reality.

Experimental psychologist Bruce Hood discusses in his book The Self Illusion (2011) and various YouTube talks how our vision is interrupted every time we shift our gaze, resulting in an accumulated blindness of approximately two and a half hours each day. Interestingly, we have two significant blind spots in our visual field, yet we remain oblivious to them since our brains compensate for the missing information.

As we navigate our surroundings, our brains process the incoming data, but this isn’t the reality we perceive at face value. Our memories and experiences heavily influence the brain’s synthesis of what we “see.”

All of this occurs in mere milliseconds, making it nearly impossible for us to grasp the underlying processes—scientific studies have only recently begun to unravel these complexities.

Moreover, technology metaphors are inescapable here. Consider the predictive algorithms at play when we search on our smartphones or scroll through social media, where we’re often presented with curated content based on what platforms think we want to see. We might believe we’re accessing endless information, but in truth, a hidden framework has already predetermined our viewing experience.

For those of us fortunate enough to possess sight, let’s cherish this gift. While we can't don stylish sunglasses and trench coats like Trinity, Neo, or Morpheus, we can take a moment to remind ourselves that…

We don’t see with our eyes. We see with our brains.
