I enjoy working Sudoku puzzles, especially the hard or challenger level, and I always look forward to the super challenger puzzles on the back pages of Dell’s Crazy for Sudoku books that take days to complete. (They look like the puzzle pictured above.)

A friend once said that she’d completed a Sudoku puzzle and, having solved it, did not see a point in doing it again. Certainly completing a puzzle successfully is one point of Sudoku, but for me it’s the incomplete puzzle that’s juicy, especially if I’m struggling with it and not sure I’ll be able to solve it.

Sudoku puzzles are a great example of one of the aspects of existential troublesome knowledge I talked about in the last blog post: what we don’t know exceeds and is more important than what we know. The numbers that are not filled in are more important than the numbers that are filled in. And there’s no way to know at the outset which numbers go in which blank spaces. You can only find out by taking action. As you fill in more numbers, you get more information, and eventually you solve the puzzle. This is a life lesson some of us struggle to learn.

There’s always a point where I feel stuck, at least with some hard or challenger level puzzles. I can’t find a next number to fill in. I used to get frustrated when I was stuck, but after going through this process so many times, I’m quite familiar with it and am no longer frustrated by it. I think Sudoku has trained my brain to recognize that being stuck is a temporary condition and so I actually appreciate the experience now.

I don’t know if or how I will solve the puzzle, but I now appreciate the space of not knowing, of uncertainty, because it’s also the space of possibilities. This is the same space I get into when I’m grappling with a conceptual problem or puzzle. And in both Sudoku and conceptual problem-solving, one is more likely to arrive at a “solution,” by trying different approaches.

If the only puzzles I have available are easy or medium level, I create “rules” to make them at least a little bit more challenging. I would never, for example, start by filling in all the 1s, 5s, or 9s I can fill in because that’s too easy. But in a challenger level puzzle, I would definitely start that way in order to get at least a few spaces filled in.

In Sudoku, there is only one correct solution to the puzzle. The same isn’t necessarily so for conceptual puzzles where my aim is usually to arrive at a provisional assessment rather than a definitive conclusion because in the conceptual world we never have all the information. But I don’t think this difference is particularly significant, and I heartily recommend activities like Sudoku to train the brain to appreciate uncertainty and to sort of force ourselves to recognize how much we don’t know—and how neither condition is either fatal or even undesirable.

Moving around Inside the Space of Possibilities

The fact that what we don’t know is more important than what we know has been a subject of discussion in classes, workshops, and individual meetings. I asked a couple of different groups to consider, write about, and summarize their responses to statements that described different aspects of our lack of knowledge. Here’s what they had to say. (The statements they are responding to are in italics.)

Our predictions about the future are constrained by the present.

When we try to imagine our future, we can only see a small slice of possibility—based on our current mental model.  The same is true about understanding our past—we do so based on who we are in the present.  When we move to a different rock, we see new things and, to some extent, lose sight of what we saw before. —Susie

We are driven to make sense of the world, whether or not the world makes sense.

It never occurred to me that one would not be able to make sense of the world. Why, all one has to do is work hard enough, read, listen, observe, and have the intelligence to integrate all the available information, and understanding will come. Right? I’ve long assumed that the world not making much sense (in many ways) was a failure on my part (I’m obviously not getting it all, nor fast enough) because of course all things must be understandable, given the right type and amount of information/instruction etc. —Lisa

Our brain habitually constructs coherent and compelling stories—tailor-made for each of us—based on the information available and our mental model of the world.

We seem to live in some illusion of reality or a unique reality to each of us that is constantly shifting towards a pre-existing story that the brain has developed.  We aren’t aware of the information that the brain is picking, discarding, ignoring or overlooking until after the fact.  How to consciously participate in this story of our own reality?  If it’s based on the information available to us and on our mental model of the world then it’s necessary to expand both, to become aware of what the brain is choosing to add to the stories. —Imelda

We prioritize cause-and-effect explanations and discount randomness (because we can’t account for it).”

How can we imagine a future without our history? Can I only imagine a future rooted in my past or can I possibly imagine a future untold? To understand that we are not divining our future but to accept that randomness plays a role in a possible eventuality serves up the possibility for change.  —Sammie

Each of us is weaving stories, not uncovering absolute truth. 

There are facts. 2+2=4. Truths are when we try to assign meanings to our perceptions of something that happened. Each of us has our own way of assigning meanings so no truths can be absolute, or shared by everyone. So we might as well weave beautiful stories, or at least useful ones. —Ann

We mistake perception for reality.

My perceptions seem to be more on the trees and not the forest. Actions and thoughts seem to be driven by a false narrative of what I perceive to be true. I can base life itself on little discussion and shoot from the hip decisions made in the small dark damp room on my shoulders, without much input from “me.” —Kelly

Our predictions about the future are constrained by coherence.

The future is way more exciting with those blinders noted. I am not even confined by my imagined trajectory! Why not create? —Adam

Onward

I invite you to consider these statements for yourself, along with the comments prompted by them. Where do they take you?

Asking ourselves what we don’t know in a given situation is useful even if we can’t answer that question just because it’s a reminder that we are always—100% of the time—operating based on limited information. Could there be something we don’t know, the knowing of which would change everything?
