Belief Is a Choice, Equality Is the Foundation - #BigF to you! - MELIH ABDULHAYOGLU

6 or 9

There are two truths that, if deeply understood, could reshape how we live together as human beings.

  1. Belief is a choice. What we call “reality” is not an objective fact but the brain’s interpretation of the inputs it receives.
  2. Equality is the foundation of society. The moment inequality is allowed, the door opens for it to be turned against us. That path always spirals into division and destruction.

Taken together, these two truths point to a profound way forward: if we accept that reality is a mental construct and that equality is the only stable social contract, we can stop fighting over “truth” and start building systems where countless subjective realities can coexist peacefully.


Part One: Belief Is a Choice

Our brains are sensory interpreters. They take raw inputs—light entering the eyes, sound waves vibrating in the ear, molecules triggering smell and taste receptors, pressure on the skin—and translate them into what we experience as “the world.”

But here’s the catch: no two brains interpret those inputs in exactly the same way.

The Color Example
Consider the color pink. Two people can stand side by side, point to the same flower, and agree: “That’s pink.” On the surface, it looks like a shared fact. But inside, their brains could be producing completely different subjective experiences. What one person perceives as “pink” could feel entirely different from how the other perceives it.

We will never know. What we do know is that society works because of aligned perception—we agree to call that flower “pink.” From the outside, this looks like a fact, but in truth it’s only an overlapping agreement.

The 6 vs. 9 Example
The same holds for symbols. Place a number on the table. From one seat, it looks like a 6. From the other, it looks like a 9. Neither perspective is wrong. Neither is the full truth. The “fact” is only what the mind interprets.

The Religion Example
Religion takes this even further. Billions of people live inside entirely different constructed realities: heaven, reincarnation, karma, salvation. None of these can be proven as objective facts. Yet each belief system organizes life, provides meaning, and defines morality for its followers. For believers, these realities are as solid as gravity.

This shows something essential: belief is not forced upon us; it is chosen.

More Everyday Proofs of Chosen Belief

  • Cilantro: Some taste it as fresh and citrusy; others as soapy and disgusting. Same leaf, different interpretations. Both are “real.”
  • Cultural Norms: In one culture, direct eye contact means respect. In another, it signals aggression. The act itself has no inherent meaning—the meaning is belief.
  • Optical Illusions: The viral dress that appeared blue and black to some, white and gold to others. Millions of people looking at the same image but inhabiting different “realities.”
  • The Placebo Effect: Sugar pills that heal, because patients believe they are medicine. Here, belief literally alters biology.
  • Social Constructs: Money, borders, job titles. None exist in nature. They exist only because we collectively choose to believe in them. A $100 bill is just decorated paper until belief gives it value.

The Dictator Example
History also warns us of what happens when someone refuses to accept that belief is a choice. Dictators and authoritarian regimes often try to impose their version of reality on entire populations.

They rewrite history books. They censor opposing voices. They punish those who disagree. The message is simple: only my perception counts, yours must be erased.

But forcing one “truth” on millions doesn’t change reality—it only creates oppression and fear. People still hold their own perceptions silently, and eventually, that suppressed divergence erupts into resistance, unrest, or collapse.

The dictator’s failure is always the same: believing that subjective reality can be made objective by force.

And that is the deeper lesson: there is no true “objective” reality. Every sight, sound, touch, taste, or thought is filtered through the brain. What we call “objective” is really just aligned subjectivity—the overlap where enough people share a similar interpretation and agree to call it fact. But the raw experience is always personal, always subjective, always a construct.


Part Two: Equality Is the Basis for Society

If reality is subjective, what keeps billions of different interpretations from collapsing into chaos? The answer is equality.

Society works only because of equal rules. Consider traffic: if red lights only applied to some drivers but not others, chaos would break out at every intersection. The system functions because everyone is bound by the same standard.

The same is true in society. The minute we accept discrimination—even subtle forms like “people from that background don’t deserve the same opportunity”—we plant a seed that legitimizes inequality everywhere. Sooner or later, that permission will be used against us. The result is a race to zero, where everyone loses.

History Gives Us Stark Reminders

  • Segregation laws didn’t just harm those excluded; they fractured communities, fueled resentment, and often exploded into violence.
  • Workplace discrimination based on gender or ethnicity has consistently wasted talent, slowed progress, and cost industries innovation.
  • Colonization imposed unequal systems across the globe, stripping resources, destroying cultures, and creating cycles of mistrust and violence that still shape societies today.
  • Everyday reciprocity: At the simplest human level, inequality and aggression invite themselves back. If you slap someone, you can expect a slap in return. Oppression doesn’t end with the act—it sparks retaliation, revenge, and escalation.

Each of these examples shows that inequality doesn’t just harm the targeted group—it destabilizes entire systems. Equality, by contrast, unlocks the full potential of human collaboration. It is not charity. It is survival.


Part Three: Bringing Them Together

Now let’s combine these two concepts.

If reality is constructed by the brain, then insisting that our perception is the only valid one is futile. It’s like arguing whether the number on the table is a 6 or a 9. Belief is a choice, and different choices will always exist.

But if we also accept that equality is non-negotiable, then we create the only stable foundation that allows diverse subjective realities to coexist. Equality doesn’t erase differences in belief—it makes space for them.

When we live this way:

  • We stop fighting endless battles over “truth.”
  • We stop trying to convert or dominate other perspectives.
  • We start focusing on building systems where multiple subjective realities can thrive without colliding destructively.

Conclusion

There is no single, objective reality—only billions of private ones stitched together by perception. Every “fact” is simply an agreement born of overlapping subjectivities.

We would argue less over truth if we understood this simple fact: there is no “truth.” Not in the way people often imagine it—as something solid, external, and unchanging. What we call truth is nothing more than aligned subjectivity—the point where enough of our private perceptions overlap that we agree to give it a label.

  • The flower is “pink” not because pinkness exists in the flower, but because enough of us agree to use that word for the experience our brains generate when light hits our eyes.
  • A law is “valid” not because justice floats in the air, but because society collectively agrees to enforce it.
  • Even scientific facts, while powerful, are models built on measurements that our senses and instruments interpret. They are not ultimate truths—they are agreements that help us act.

Once we realize this, endless fights over who holds “the truth” look misguided. There is no throne of truth to sit on—only perspectives, interpretations, and agreements.

And so, if reality itself is subjective, the only thing that can hold billions of subjectivities together is equality. Equal dignity, equal respect, equal rules. Equality doesn’t erase differences in belief—it creates the space where differences can coexist without tearing society apart.

If more people embraced this—that belief is a choice, that truth is only aligned perception, and that equality is the glue binding us—we would stop trying to conquer each other’s realities and instead build a world where dignity, opportunity, and trust belong to all.

and we call this:

The “Big F” Principle

To make these two truths easier to remember and share, let’s give them a name:

BICIF — Belief Is a Choice, Equality Is the Foundation.

Pronounced “Big F” (/bɪɡ ɛf/ in phonetics), this captures the two pillars we’ve been exploring:

  • Belief is a Choice (BIC) → Reality is not given, it’s constructed.
  • Equality is the Foundation (IF) → Society survives only on equal respect and rules.

Together they form BICIF“Big F.”

Why “Big F”? Because these two principles are not small ideas—they’re big, foundational truths. They shape how we see the world and how we live with others.

Sharing this learning is as simple as using the hashtag #BigF. It’s a reminder that:

  • There is no objective truth—only aligned subjectivities.
  • Belief is chosen.
  • Equality is the non-negotiable foundation for coexistence.

If these three lines spread, they could reframe countless arguments, policies, and personal interactions.

#BigF to you!
