Figure 1. Rene Descartes quote on Naive Realism

We often assume that our perceptions are accurate and objective reflections of reality, but they are actually mental constructs shaped by our minds. This cognitive distortion, known as the "bias blind spot" or "naïve realism," is one of the most widespread cognitive bias in society. It's so pervasive that it often leads to a related bias called the "assumed similarity bias," where individuals believe that their personal interpretation of the world is shared by others.

Contrary to the belief that our perceptions mirror reality, human perception is an abstraction, not a replication, of the world around us. Our brains construct an internal representation of external events by analyzing various features. For example, colour perception is not a direct reflection of reality; colours are synthesized by our brain to differentiate light wavelengths. This means colour is an illusion, and it's uncertain if other animals perceive it as we do.

This assumption of objectivity persists because our brain's model of the world feels real, aiding our survival. Acknowledging the subjectivity of our perceptions can be uncomfortable and challenge our beliefs, leading to cognitive dissonance. Societal norms further reinforce this belief in objectivity, rewarding confidence and discouraging questioning.

However, recognizing our biases is essential. While our perceptions are subjective, this doesn’t mean all perceptions are equally valid or that objective truth doesn’t exist. It simply means we must actively challenge our cognitive biases to approach a more accurate understanding of the world.

-Contrary to the "''objective reflection''" assumption, perceptions are not precise copies of the world around us. Sensation is an abstraction, not a replication, of reality. The brain’s circuits construct an internal representation of external physical events after first analyzing various features of those events. When we hold an object in our hands, the shape, movement, and texture of the object are simultaneously analyzed in different brain regions according to the brain’s own rules, and the results are integrated into a conscious experience.
+Contrary to the belief that our perceptions mirror reality, human perception is an abstraction, not a replication, of the world around us. Our brains construct an internal representation of external events by analyzing various features. For example, colour perception is not a direct reflection of reality; colours are synthesized by our brain to differentiate light wavelengths. This means colour is an illusion, and it's uncertain if other animals perceive it as we do.
-The easiest example of this is colour perception. We can argue that colors are not real—they are “synthesized” by our brain to distinguish light with different wavelengths. While rods give us the ability to detect the presence and intensity of light (and thus allow our brain to construct the picture of the world around us), specific detection of different wavelengths through independent channels gives our view of the world additional high resolution. For instance, red and green colors look like near identical shades of grey in black and white photos. Why certain wavelengths are paired with certain colors remains a mystery. Technically, color is an illusion created by our brain. Therefore, it is not clear if other animals see colors the same way we see them. It is likely that, due to shared evolutionary history, other vertebrates see the world colored similarly to how we see it. But color vision is quite common across the vast animal kingdom: insects, arachnids, and cephalopods are able to distinguish colors.
+This assumption of objectivity persists because our brain's model of the world feels real, aiding our survival. Acknowledging the subjectivity of our perceptions can be uncomfortable and challenge our beliefs, leading to [[cognitive dissonance]]. Societal norms further reinforce this belief in objectivity, rewarding confidence and discouraging questioning.
-There are several reasons why this assumption is so prevalent. First, it's a natural outcome of how our brains process information. Our brains take in information from our senses and construct a model of the world that feels objective and real to us. This model helps us navigate the world and make decisions, so it's beneficial for our survival and success.
+However, recognizing our biases is essential. While our perceptions are subjective, this doesn’t mean all perceptions are equally valid or that objective truth doesn’t exist. It simply means we must actively challenge our cognitive biases to approach a more accurate understanding of the world.
-Second, acknowledging that our perceptions are subjective can be uncomfortable and can cause [[cognitive dissonance]]. It introduces uncertainty and can challenge our sense of self and our beliefs. Therefore, we often resist acknowledging our biases and maintain the belief in our objectivity.
-Finally, societal norms and structures often reinforce the assumption of objectivity through the [[Status Quo Bias]] reaffirming the idea of a [[Consensus Reality|consensus reality]]. For example, in many cultures, people are rewarded for being confident and certain, which can discourage people from questioning their own perceptions and beliefs.
-However, it's important to note that while we all have biases and our perceptions are inherently subjective, this doesn't mean that all perceptions are equally valid or that objective truth doesn't exist. It simply means that achieving a more objective understanding of the world often requires us to actively acknowledge and challenge our [[Cognitive Biases|cognitive biases]].
