I can't help but relate and intertwine the concepts and ideas of brilliant minds. Everything seems interconnected —what appear to be separate subjects often turn out to be different perspectives on the same fundamental truths.
To be more specific, last year I took a course on the Big Five Personality Traits (also known as OCEAN), which broadened my understanding of self-knowledge. It gave me deep insights into the motivations behind my actions, preferences, emotions, thoughts, strengths and limitations.
And when I came across the works of Brian Little and George Kelly, I realized that their ideas were deeply interconnected, all pointing to the same central principles.
In this post, I intend to explain how concepts from George Kelly and Brian Little relate to Freud's idea of the ego, as well as the interaction between fate and free will in shaping who we are.
The Equation of our Personality
Our personality is the set of enduring mental, emotional and behavioral patterns of mechanisms that operate and respond in unique ways to different situations. In other words, it's what makes us authentic.
So the equation of our personality, according to Brian Little, is as follows:
[ Biogenic Roots ]
×
[ Sociogenic Roots ]
×
[ Idiogenic Roots (Life Story + Personal Projects)]
=
Your Personality
Let's break it down:
Biogenic roots
They are simply your genes—your unique physical characteristics and biological functions passed down through your parents' DNA. Our biogenic root shapes at least 50% of our personality.
Sociogenic Roots
These are the social, cultural and environmental influences on our behavior.
Idiogenic roots
They are the story of our lives—what happened to us—combined with our personal projects, which are what we create for ourselves, in other words, what and how we want our lives to be.
Therefore, our personality arises from the interaction of these three roots. In addition to these elements of our personality, we develop a complex system of personal beliefs—what George Kelly called personal constructs—so that we can sustain and give meaning to our identity.
And what are Personal Constructs?
Personal constructs are mental frames with opposing concepts that we use to interpret and classify behaviors or situations, shaped by our personality and experiences. In other words, they are the way we see things in contrasts, such as trustworthy vs. untrustworthy, chaotic vs. organized, flexible vs. rigid, and generous vs. selfish. They are the duality in ourselves.
The personal constructs have three important aspects:
- They are unique to each person, as they are shaped by the individual's personality and life experiences;
- They consist of two opposing concepts for interpreting, comparing and assigning meaning;
- They change and adapt over time in response to new experiences.
In a nutshell, our identity is like this:

My interpretation of this, combined with psychological concepts, is as follows:

Personal Constructs and the Ego
In my view, the personal constructs are simply another way of understanding the ego.
Our personality is the most stable element in our lives. It undergoes substantial changes only during transitions or critical life events that force us to form new habits and behaviors.
As these changes can be painful and even threatening, the ego (or personal constructs) acts as a protective layer, offering coherence, stability and continuity. It, therefore, helps us maintain a reliable connection between our internal world and the external world.
Returning to the personality equation, to a certain extent, we are all biologically similar. Large groups of people share the same biological conditions, just as many individuals experience similar sociogenic influences.
However, when it comes to the idiogenic roots, things change - this is where individuality emerges. Unlike the other two factors, the idiogenic root is deeply personal—it holds the refined and intricate essence of what makes you, you. It is the subtle yet defining factor that shapes your true self.
The role of Fate and Free Will in shaping the Self
Bringing these ideas into a more spiritual perspective, my interpretation is that our destiny is largely shaped by our biogenic and sociogenic roots.
These factors determine statistical probabilities, influencing the likely outcomes of our lives based on our genetic and environmental conditions.
On the other hand, our idiogenic roots generate different results. This is where free will and self-awareness lie, allowing us to drastically alter the outcomes imposed by our biogenic and sociogenic roots. Thus, life is a dynamic interaction between destiny and free will.
For example: a person born with a genetic predisposition to anxiety (biogenic root), and raised in an unstable and unpredictable environment (sociogenic root), is statistically more likely to develop mind disturbing behaviors, difficulty coping with change and low self-esteem. These patterns are not deterministic, but indicate more likely paths (so-called "destiny") if no idiogenic force—such as self-awareness or a transformative personal project—intervenes (so-called "free will").
However,
Two crucial points must be considered:
First,this leads us to consider a difficult reality — some people may never experience true self-awareness or the ability to free themselves, in other words, they don't have free will.
This can include individuals with severe neurological conditions or those raised in hostile environments where their biogenic or sociogenic roots severely limit the development of their idiogenic roots.
In these cases, their capacity for personal growth is, in a way, hijacked before they even have a chance to develop.
Second, remember that this is a multiplication equation, not a simple sum. This means that the variables don't just add up — they amplify each other.
Now, think about what that really implies for us— the endless possibilities of how our lives unfold. We don't know the exact numbers in this equation, and they are constantly changing.
So, in the overall context, it all comes down to one mysterious force: the randomness of life.
In the end, our lives are shaped by a mixture of biology, environment and personal choices.
Our biogenic and sociogenic roots may set the stage, but it is in our idiogenic roots—our conscience, our personal projects and our life story—that we find the power of shaping who we are.
As personality is a multiplication of these forces, even a small change in one area can lead to a completely different results.
So, although randomness plays its part, free will is not an illusion — it is the silent force which allows us to change direction, rewrite patterns and break out of what seems to be set in stone.
So who are we?
Are we just a product of an equation with infinite results? Well, yes—but perhaps the crucial aspect lies in the constructs that we chose to build and in how willing we are to break them to access the core of our uniqueness.
