System 1 versus System 2 thinking.

I loved Kahneman’s book, “Thinking, Fast and Slow”. The bat and ball question is a perfect example. Even though I’ve read it many times, that same System 1 reaction still flashes to mind.

Of course it is 10 cents. Wrong.

The insights in Kahneman’s research are indisputable. Scientifically validated in study after study. But the soundness of the theory itself got me thinking.

The distinction between System 1 and System 2 thinking is clear in the examples we have. But are we narrowly categorizing thinking into only two categories? Is it more than a simple bifurcation? Or, as with so many human cognitive processes, are we really measuring a spectrum?

Some ideas are firmly System 1. So deeply and reflexively at the top of mind that we act before conscious thought even begins. And thank God we do. As Kahneman noted, the lion might eat us while we sit there considering the probability of attack.

But what is it that embeds quick thinking into System 1 in the first place?

I think of the trained athlete or musician who worked for years to perfect their craft. For them, muscle memory clearly functions within System 1 in a way we weekend warriors and musical novices can only watch in awe.

At what point in their careers did the thinking move from System 2 to System 1?

What was it a researcher once claimed? Ten thousand hours? Thirty thousand hours? Whatever the number, where is the thinking at the halfway point? Somewhere between Level 2 and Level 1? Somewhere in between conscious effort and automatic recognition?

And what about reaction time?

Surely math experts answer the bat and ball question correctly much faster than those of us who still have to pause and shift into more contemplative consideration.

So is the distinction between System 1 and System 2 measured by reaction time? Or by something else entirely?

Then I started thinking about examples much closer to home.

Where does the QWERTY keyboard sit?

When I first learned to type, every key required conscious effort. Today, I can type for hours without thinking about it. In fact, if you asked me to point to a particular key without looking, I might hesitate. Yet my fingers somehow know exactly where to go.

Where does my daily drive on the New Jersey Turnpike sit?

I cannot honestly recall which exit I just passed without the GPS anchor sitting on my dashboard. Yet somehow I remain in my lane, maintain my speed, anticipate traffic, and arrive safely at my destination.

Am I driving on instinct? Or am I executing learned behaviors that over years have migrated from System 2 into something that now feels like System 1?

The more examples I considered, the less convinced I became that all “fast thinking” is the same thing.

The novice answering 10 cents appears to be using System 1.

The concert pianist appears to be using System 1.

The veteran CFO who walks into a room and immediately senses something is wrong with the numbers appears to be using System 1.

But are those really the same phenomenon?

One may be instinct.

Another may be expertise.

Another may be decades of analysis compressed into recognition.

That thought was rattling around in my head when I read a LinkedIn post that triggered all of this.

The post claimed that wisdom implies slower reaction time, while aggressive, innovative companies require energetic risk-takers who are still hungry.

Really?

Are we describing a System 1 thinker eager to advance versus a System 2 thinker who has been there and done that and is no longer excited by the novelty of the pursuit?

Are we describing someone in their prime versus someone past their prime?

Or is the post really arguing that the more experienced thinker is simply less motivated to engage in deeper analysis because they are satisfied with the conclusions already embedded in their learned thinking?

To be fair, perhaps there is some truth there.

Maybe the experienced CFO really does look at a problem and think, “I’ve seen this before.”

Maybe experience sometimes becomes a filter.

Maybe it is easier to paint on a blank slate than one cluttered with old fragments.

Maybe it is easier to design and install a brand-new system than it is to simultaneously unlearn and decommission an old one.

The idea of motivation carrying some truth is not difficult for me to accept.

My concern comes from the labeling.

The post seemed to divide people into neat categories.

Young and old.

Hungry and comfortable.

Innovative and experienced.

Fast and slow.

But the more I thought about Kahneman’s work, the athlete, the musician, the keyboard, the Turnpike, and the experienced executive, the less comfortable I became with the categories themselves.

The human mind may not operate through two neat systems at all.

Perhaps it operates along a spectrum.

Perhaps instinct, learned behavior, expertise, intuition, analysis, reflection, and creativity all occupy different points along that spectrum.

And perhaps the same is true of people.

The more I thought about it, the less interested I became in whether the LinkedIn post was right or wrong.

Instead, I found myself questioning our tendency to place people into buckets in the first place.

System 1 or System 2.

Young or old.

Hungry or comfortable.

Innovative or experienced.

Reality is probably much messier than that.

I am no expert on any of this. I’ve never conducted a social experiment. I feed off the great work of others, like Kahneman.

But then I read an innocent LinkedIn post and start asking questions.

And maybe that is the point.

It is the Kahnemans of the world who keep us thinking.

And as I think, I wonder whether even his work may have only cracked the surface.

The human mind is extraordinarily complex. Our labels don’t do it justice.

Just my theory.

But I think that is what makes human thought so interesting.

And it also enables us to look at even the most innocent LinkedIn posts a little more critically—and hopefully a little more objectively.
