Why You Donât Always Act the Way You Intend To
I remember a moment in a meeting a few years ago. A team member pushed back on a decision I had made. It wasnât what he said, it was how he said it. Something about the tone didnât sit right with me. Honestly, I felt offended inside.
I reacted almost instantly - I cut him off, defended my position, and moved the discussion forward. While the meeting continued, I could sense that the energy in the room had shifted - everyone went quiet, and there were no more questions or pushbacks.
At the time, it felt like I had handled it, but later that day, I kept replaying the moment in my head. The more I thought about it, the more uncomfortable it felt. I knew that he wasnât wrong, and he had a valid point. I also knew deep in my heart that I hadnât responded to the idea, I had reacted to how it made me feel.
And thatâs when it hit me.
In that moment, I wasnât leading - I was reacting.
If Iâm honest, youâve probably had moments like this too. It may have been a comment in a meeting, a missed deadline, or a message that felt slightly off. And before you know it, youâve reacted in a way you didnât intend. Or you overthink, delay your response, and say nothing at all. And later, you ask yourself, âWhy did I do that?â
Thatâs the part most people donât talk about. In this issue, Iâll unpack the Three Brains Framework, which explains whatâs really happening in your mind when you react, overthink, or freeze.
Ready? Letâs dive in!
đ§ The Three Brains Framework
If I were to tell you that you have not one, not two, but three brains, youâd probably think Iâm joking, right?
Well, Iâm not. Let me explain.
At any moment, one of three systems in your brain is driving how you think, feel, and act. In fact, most of the time, youâre not even aware of which one is in control.
Letâs look at each system.
⥠The Reactive Brain (Survival Mode)
This is your fastest system, and itâs built to protect you.
It scans for threats - both physical and social. A threat could look like a challenge in a meeting, a missed deadline, or even a tone that feels off (remember the story I shared at the beginning?) It treats all of these as signals that something is âwrongâ.
When this brain takes over, you donât pause. You react.
In a leadership setting, the âreactionâ shows up quickly.
You interrupt someone mid-sentence.
You shut down ideas that feel risky.
You push back harder than needed.
Sometimes you go silent, not because youâre thinking, but because youâve disengaged.
It feels decisive in the moment, but what itâs really doing is protecting you, not helping you lead.
â¤ď¸ The Emotional Brain (Social Mode)
This is your ârelationshipâ system.
This system reads people. Itâs great at picking up tone, body language, and intent. Itâs also where trust, fear, and belonging live. And importantly, this brain is critical for leadership, because leadership is human.
But thereâs a catch: this brain also has a bias.
It doesnât just read situations, it interprets them. In your world as a leader, this shows up in subtle ways:
You start favoring people you feel comfortable with.
You avoid giving tough feedback because it feels uncomfortable.
You take things personally, even when theyâre not meant that way.
You might delay a decision because it âdoesnât feel right,â even when the logic is clear.
This brain helps you connect with people, which is necessary, but when it dominates your thinking, it can cloud your judgment.
đ§ The Thinking Brain (Rational Mode)
This is your rational brain.
It looks at data, weighs trade-offs, and focuses on outcomes, not reactions or feelings. It helps you to make rational, data-driven leadership decisions.
When this brain is in charge:
You ask better questions.
You listen fully before responding.
You separate the idea from the person.
You focus on what needs to be done, not how the moment feels.
In practice, this is when you handle a tough conversation calmly. You make a decision thatâs right for the team, even if itâs uncomfortable.
How It Actually Works (The Hidden Problem)
Now, in reality, you donât switch between these three brains consciously. They switch for you.
And the problem is: in most situations, they donât collaborate. They compete with each other, and the one that takes âwinsâ isnât always the one you want.
Your reactive brain is built for speed. It doesnât wait for the context, and it doesnât check for accuracy. It sees a threat and acts. Thatâs how itâs wired from the times when we (humans) were hunter-gatherers, and it was useful then when we were in ârealâ danger facing hunger or a threat in the wild. But itâs less useful when someone disagrees with you in a meeting.
Your emotional brain is slightly slower, but still quick to interpret. It fills in the gaps, assigns meaning and interpretations. It decides how something feels before youâve fully understood whatâs actually happening.
Your thinking brain is slower, and is built for rational judgment. It needs time and space to weigh the options, and consider the outcomes. But by the time it fully engages, the other two have often already acted.
And that is the âhidden problemâ.
When you are in high-pressure moments, because of the way itâs wired, the control shifts away from your thinking brain to the other two.
This is why the same patterns show up again and again.
You react before you think.
You take things personally.
You overanalyze simple decisions.
You avoid conversations you know you should have.
Applying The Three Brains Framework in Leadership
You canât learn leadership by reading alone. The real test happens in high-pressure moments, when youâre triggered, and what matters is whether you have a system to respond, not just react.
In the rest of this article, we will focus on applying this framework in practice in your own leadership situation.
