8 filters that block you from seeing reality


Our reality is a filtered version of the world

Reality is not perceivable as is
What we perceive as Reality is a filtered version so we can take action and live in the World.

The world has too many details to be perceived and most of them are of no use to the present situation and are therefore not processed by the brain.

Filter 1 – We cannot see it all

The first limitation is spacial and temporal, one cannot be everywhere all the time.

One might say this is obvious, but that statement has a corollary truth in it, which is we cannot know what led something or someone to be as is when we encounter it.

So we just see the end result and appearances can be misleading.

We also cannot perceive what is out of sight or earshot. So the hidden part of things -the back of cards, the inside of a box, etc.- is not available for our analysis.

Of course, we can easily be aware of these two limitations, but it is difficult to keep in mind what is unknown.
The brain is wired to register what exists. Keeping track of what does not exist requires special mental capacities only humans have.
Still, we quickly forget that we don’t know what we don’t know and make a certainty of the part we can perceive.

We are missing what is missing.

— David McRaney, You Are Not So Smart.

Filter 2 – Our sensory limitations

These are the limitations of our toolbox.

  • Our eyes can only see some wave lengths and have a limited resolution.
  • Our ears can only capture a certain range of sounds.
  • Our skin can be sensitive to pressure only to some extent.
  • Our nose can only sense a limited range of smells.
  • Our tongue can only distinguish five tastes.

For instance:

  • Cats can hear sounds inaudible to dogs.
  • Dogs can hear sounds inaudible to teenagers.
  • Teenagers can hear sounds inaudible to adults.

Bees can see infrared and pigeons can perceive more colors than we can.
Cats vision is very different from the vision of humans.

So what we call Reality is different for everyone.
Even among humans. Nearsighted people’s world is different than other people’s world.

These limitations have a purpose

In fact, our fives senses of sight, smell, hearing, touch, and taste, are not designed to capture all the emissions from the outside world, but to capture what is essential to our survival.

For instance, we are unable to sense the direction of the Earth magnetic field because it would be useless information to us but migratory birds can sense it because it is an essential information to them.

Yet this magnetism is constantly present as a compass can show.

In fact, our sensory system main function is to discard what is useless more than capturing what is useful.

Otherwise, there would be way too much information out there to deal with. (Gamma rays, Microwaves, Xrays, Radio waves, etc.)

The information is there but we are oblivious to it although we are bombarded with it all the time. The proof is, a cell phone in our pocket will capture some radio waves we are unaware of.

Filter 3 – The limitations of our brain

Not everything that is received by the ears, eyes, and skin is translated into neural stimuli -essentially the job of Brain 1.
Not even a millionth of that neural stimuli is ever reaching the conscious brain.
What does reach the conscious brain -Brain 3- has been tweaked by many other things.

Filter 4 – Our Paradigm

The following filters (5 to 8) are influencing each other and precedence is hard to define, yet the mother of all brain filters is our Paradigm.

Our Paradigm is the set of psychological filters we have in place. It is our view and opinion of the world. It is made of our preferences, our prejudices, our fears, our hopes, and desires.

Most of them are actually totally hidden in our unconscious. Their actual motivation and origin are often unknown. We don’t even know we base our opinions and judgment on that set of filters because everything we end up knowing has been filtered itself.
If we were fishes, we would not be able to know what water is. Because we wouldn’t know that air or land existed. We would have nothing to compare to our liquid world. Our liquid world would be just that: the world as we know it.

To a worm in horseradish, the world is horseradish.

— Yiddish proverb

These filters are often created in infancy and are usually difficult to identify and even harder to change.

The Paradigm is what stops most external stimuli from reaching the conscious brain. Although that filtering is a necessity because our conscious brain (NeoCortex a.k.a. Brain 3.0) cannot handle the millionth of what the sensory brains can capture, it, of course, leads to a major distortion of the original facts.

Filter 5 – Primers and anchors

Another set of filters is all the influences from external sources. Psychologists call these Primers, Anchors and other fallacy generators.

Advertisement and marketing are very fond of these entry points. But anything in sight can do the trick (after having been filtered by all the above, of course).

For instance, Daniel Kahneman (Thinking Fast and Slow) demonstrated that a randomly picked number can influence how many African countries people estimate to be members of the U.N.

The commercial application is to present more expensive options to consumers so they convince themselves that an item is a bargain.

Filter 6 – Fallacies, delusions and biases

These are natural behaviors based on primal experiences and driven by basic instincts.

We all have them, they are part of the human toolkit and are due to various interactions between the three main parts of the brain (1,2 and 3).

They are the Confirmation Bias, the Self-Fulfilling Prophecies, the Loss Aversion, the Hindsight Bias, etc.

I highly recommend you seek to get more information about these fallacies on David McRaney’s Blog, You Are Not So Smart. He is the master of Delusion.

These delusions are shaping how we perceive the world.

For instance,
Say a group of patients has a fatal disease. They are all doomed to die from it.

  • A treatment (#1) is available but 25% of the patients may die anyway.
  • Another treatment (#2) is also available and will save 75% of the patients.

Most doctors would recommend treatment #2 although the odds of saving patients are the same.
The choice is motivated by the difference in the perception.
This is called Loss Aversion and we cannot help it.

In a test, various medical papers discussing the same situation with the same 25/75 distribution was to a group of doctors.

  • Pessimistic people (and opponents of the treatment) will recall the treatment killing 25% of patients.
  • Optimistic people (and supporters of the treatment) will recall the treatment saving 75% of patients.

That is Confirmation Bias.

We see and seek what we want to see and find. We will read in depth what supports our Beliefs but only give a superficial look to what does not. Unless we are looking for its flaws, of course…

Awareness is the best weapon against Delusions.

When asked about the chances of her husband John Kerry to be elected president, Teresa Heinz, aware of the Confirmation Bias, replied: “I don’t know, we only mingle with Democrats”.

Filter 7 – Filling the Blanks

So when we have all the fact we will already distort them.
But in real life, we usually don’t even have all the facts.

So the brain is filling the blanks.
When something is amiss, the brain cannot accept being unable to figure it out. It must come up with an explanation so to be able to act on it.

The brain resolves ambiguity using prior knowledge and other factors such as personal preferences and all of what constitutes our Paradigm.

The feature image of this post is just a hash of lines but everyone can see a Heart in it.

This capacity was intended to resolve life-threatening problems with limited information.

It is what makes optical illusions entertaining but it has its drawbacks when unaware and unwilling to admit its influence.
We can come to be certain about things that are partially fabrications.

Filter 8 – Context

  • In a room filled with people we hear many voices but ignore most of them.
  • At home, we are attuned to each familiar voice and can immediately react to them.
  • In the wilderness, the slightest hint of human voice would prompt immediate attention.

The same person saying the same thing the same way would be perceived completely differently in each of the situations above. We may not even hear it in the first case.

Awareness is key

Our perception of Reality is actually more like the telephone game, in which a message is passed down a line of players by whispering into each other’s ear. The end product is a gross distortion of the original message for the great amusement of all.

Here the participants of the game are replaced by our senses, preferences, opinions, external influences, delusions, fallacies, filling-the-blanks fabrications and context.

Do not be so sure of what you call Reality.
Take the time to question your own perception.
Be aware of your own filtered perception.
