Course Corrections & How to Consume Non-Fiction by Mark Hatmaker


A preview of what follows to see if this is your cup of pragmatic tea.

·        The difference between course, heading, and bearing.

·        The vital importance of course corrections in physical life and cognitive life.

·        How to test non-fiction for utility.

·        I emphasize, how to test ANY non-fiction book from physical geography, to the latest super-duper diet to philosophy. It is a vital time-saving hack to know when to keep a book always on your desk, in your mind, or when to toss it on the garbage heap.

·        And we end with a mini book-review.

First, let’s give the stage to author and amateur pilot Rolf Dobelli. This is from his volume The Art of the Good Life.

“You’re sitting on a plane from London to New York. How much of the time is it sticking to the flight path, do you think? 90 percent of the time? 80 percent of the time? 70 percent of the time?

The correct answer is never. Sitting beside the window, gazing out at the edge of the wing, you can watch the jumpy little ailerons—they’re there to make constant adjustments to the flight path. Thousands of times per second, the autopilot recalculates the gap between where the plane is and where it should be and issues corrective instructions.

I’ve often had the pleasure of flying small planes without autopilot, when it’s my job to carry out these minuscule adjustments. If I release the joystick even for a second, I drift off course. You’ll recognize the feeling from driving a car: even on a dead-straight motorway, you can’t take your hands off the wheel without veering out of your lane and risking an accident.

Our lives work like a plane or a car. We’d rather they didn’t—that they ran according to plan, foreseeable and undisturbed. Then we’d only have to focus on the set-up, the optimal starting point. We’d arrange things perfectly at the beginning—education, career, love life, family—and reach our goals as planned. Of course, as I’m sure you know, it doesn’t work like that. Our lives are exposed to constant turbulence, and we spend much of our time battling crosswinds and the unforeseen caprices of the weather. Yet we still behave like naïve fairweather pilots: we overestimate the role of the set-up and systematically underestimate the role of correction.

Beautifully done, Mr. Dobelli.

Now three definitions.

Course-The direction we wish to travel.

Heading- The direction our aircraft, our boat, our car, or we ourselves are facing at the moment.

Heading is not always the desired direction. Say Mr. Dobelli’s aircraft, is moving against a crosswind or you and I may be hiking due north but encounter a downed tree and veer our physical heading due west to navigate around the tree, but our course-intent and desire is to return to a due north course.

Bearing- The angle in degrees (clockwise) between North and the direction to the destination. [We will deal with bearing no more today.]

In day-to-day physical and cognitive navigation we must never lose sight of our desired course, but be aware that we are making minute heading adjustments practically moment to moment.

The Importance of Getting It Right From the Start, or Intolerance to Error

Let’s hand over the stage again to another, this time Antone Roundy.

If you're going somewhere and you're off course by just one degree, after one foot, you'll miss your target by 0.2 inches. Trivial, right? But what about as you get farther out?
  • After 100 yards, you'll be off by 5.2 feet. Not huge, but noticeable.
  • After a mile, you'll be off by 92.2 feet. One degree is starting to make a difference.
  • After traveling from San Francisco to L.A., you'll be off by 6 miles.
  • If you were trying to get from San Francisco to Washington, D.C., you'd end up on the other side of Baltimore, 42.6 miles away.
  • Traveling around the globe from Washington, DC, you'd miss by 435 miles and end up in Boston.
  • In a rocket going to the moon, you'd be 4,169 miles off (nearly twice the diameter of the moon).
  • Going to the sun, you'd miss by over 1.6 million miles (nearly twice the diameter of the sun).
  • Traveling to the nearest star, you'd be off course by over 441 billion miles (120 times the distance from the earth to Pluto, or 4,745 times the distance from Earth to the sun).”
Mr. Roundy used a mere 1-degree error. But…and I wager you know this in your soul already, most errors are of a greater margin than 1 degree. Any error-margin greater than one compounds our course failure exponentially.

Getting things right from the start and keeping our eyes on course corrections as never-ending heading adjustments steal attention is, perhaps, the be-all end-all of getting to, well, anywhere.

Testing Books, Philosophies, Creeds, Assumptions, Fads & Fashions for Utility
We will use a single book to illuminate the course-correction tool emphasized in bold above.

The Book: Wayfinding: The Science and Mystery of How Humans Navigate the World by M. R. O’Connor.

Confession: The book’s topic is up my alley. It is also beautifully written, and I’d be a liar if I did not say that I found copious additional reading/research buried in the source notes but…

Any non-fiction book, lecture, YouTube commentary, podcasts, anything making claims on reality should be tested for disconfirmation.

That is, we often simply seek to confirm our pet topics and issues rather than seek to disconfirm.

For example, we read a book on the Paleo diet and get all excited and do nothing but read Paleo blogs and Paleo articles that agree with our diet du jour.

We would be wiser to read/consume any non-fiction, then ponder if it strikes a little spark of interest in us. If it does, before we plunge in headfirst, we should seek to disconfirm the new idea and then weight if we give credence to any disconfirming evidence we may find.

Why? A mere one degree of error…

Back to the book. Beautifully written, beautifully argued and…that is always part of the danger of getting lazy with our disconfirmation. Subjects that we already adore and prose or GIFs, or podcast voices that lull us into agreed complacency are all the more dangerous as we fall down on the job of keeping our eyes on constant course correction.

One counter-factual in an entire volume may not mean the entire book, the entire philosophy, the entire run of TEDTalk lectures is smoke and mirrors, but…it should make us walk warily.

From our exampled book…

“…nearly every animal that has been tested thus far demonstrates a capacity to orient to the geomagnetic field. Carp floating in tubs at fish markets in Prague spontaneously orient themselves in a north-south axis. So do newts at rest, and dogs when they crouch to relieve themselves. Horses, cattle, and deer orient their bodies north-south while grazing, but not if they are under power lines, which disrupt the magnetic fields. Red foxes most always pounce on mice from the northeast. These organisms must all have some kind of organelle that functions as a magneto-receptor, the same way an ear receives sound and an eye receives space.” Pg. 91.

Pretty neat, huh?

Just the sort of practical natural hacks I crave and backed up with science and a postulate for how it works.

One problem—Almost certainly none of it is true.

I cannot vouch for carp in fish markets in Prague but…

·        My property is flush with newts and I witness no compass directed rest.
·        After reading this passage I watched my dog carefully over the course of a week, she is all over the map and all over the compass.
·        I see horses and cattle weekly—with power lines and without, far more wily-nilly positioning than this passage would indicate.
·        Deer feed on my property often, they orient toward possible escape or possible oncoming threat not some north-south edict.
·        And we hosted a mother red fox and her three young kits this spring and had ample opportunity to watch her hunt and teach hunting to the kits. Pouncing was catch-as-catch-can.

So, beautiful prose, a subject I love, the passage before I tipped my hand that something was hinky sounds like one of those neat “factoid” things we read and feel smartified, but it is almost certainly all false. [Again, can’t vouch for the carp.]

This one paragraph being in error does not mean the work is useless and every other sentence may be a clarion of accuracy but…in a world of choices and time being finite do I need to spend more time proving errors are not as wrong as wrong is, or get back on the stick and seek course correction?




In a sense, tossing weak books, weak creeds, weak pet notions is course correction in and of itself.

Every wrong or “not really right” idea we can toss gets us closer to a useful heading and a corrected course.

Apache Running by Mark Hatmaker

Of the many Native American tribes of the southwest United States and Mexico the various bands of Apache carry a reputation for fierceness, resourcefulness, and an almost superhuman stamina. The name “Apache” is perhaps a misnomer as it refers to several different tribes that are loosely and collectively referred to as Apache, which is actually a variant of a Zuni word Apachu that this pueblo tribe applied to the collective bands. Apachu in Zuni translates roughly to “enemy” which is a telling detail that shines a light on the warrior nature of these collective tribes.             Among the various Apache tribes you will find the Kiowa, Mescalero, Jicarilla, Chiricahua (or “Cherry-Cows” as early Texas settlers called them), and the Lipan. These bands sustained themselves by conducting raids on the various settled pueblo tribes, Mexican villages, and the encroaching American settlers. These American settlers were often immigrants of all nationalities with a strong contingent of

The Empirical Fighter: Rules for the Serious Combatant by Mark Hatmaker

  Part 1: Gear Idealized or World Ready? 1/A: Specificity of Fitness/Preparation If you’ve been in the training game for any length of time likely you have witnessed or been the subject of the following realization. You’ve trained HARD for the past 90 days, say, put in sprint work and have worked up to your fastest 5K. Your handy-dandy App says your VO2 Max is looking shipshape. You go to the lake, beach, local swimmin’ hole with your buddies and one says “ Race you to the other side!” You, with your newfound fleet-of-foot promotion to Captain Cardio, say, “ Hell, yeah!” You hit the river and cut that water like Buster Crabbe in “ Tarzan the Fearless ” with your overhand stroke….for the first 50 yards, then this thought hits as the lungs begin to gasp for air, “ Am a I gonna die in the middle of this river?” This experiment can be repeated across many domains of physical endeavor. ·         The man with the newfound Personal Record in the Bench Press getting smoked in

The Original Roadwork by Mark Hatmaker

  Mr. Muldoon Roadwork. That word, to the combat athlete, conjures images of pre-dawn runs, breath fogging the morning air and, to many, a drudgery that must be endured. Boxers, wrestlers, kickboxers the world over use roadwork as a wind builder, a leg conditioner, and a grit tester. The great Joe Frazier observed… “ You can map out a fight plan or a life plan, but when the action starts, it may not go the way you planned, and you're down to the reflexes you developed in training. That's where roadwork shows - the training you did in the dark of the mornin' will show when you're under the bright lights .” Roadwork has been used as a tool since man began pitting himself against others of his species in organized combat. But…today’s question . Has it always been the sweat-soaked old school gray sweat suit pounding out miles on dark roads or, was it something subtler, and, remarkably slower? And if it was, why did we transition to what, and I repeat myself,
