What kid would think this through?

Published October 13, 2023  ·  All posts on Oct 13  ·  

In high school I had a class where your final grade was based on a total number of points earned through the semester. The final exam was worth a large portion of the total semester points—let’s say it was 500 of your semester’s possible points. Your percent-score on the exam determined how many of those points you received. (Ace the exam, and you get all 500 points.)

The exam was many hundreds of multiple-choice questions; The exam was so long that no one could ever finish it. The questions had to be shuffled to mix the material taught in the course. Every year the questions were identical, but each year the teacher made a copy of the master list, cut up (yes, with a scissors) the questions, shuffled the strips, and then taped the questions onto a sheet with question numbering, to create a unique Frankenstein-exam every year. This Franken-xam was then photocopied (via a Volkswagen Beetle sized behemoth in the main office) to produce the actual exams.

In the days before the exam, we were told to work at our own pace, to answer each question (skips counted as wrong answers) and to simply stop when time was called. Afterwards, the teacher would calculate the average number of questions attempted by the class. That average was then used as the possible number of questions for calculating our exam scores. (Thus the shuffling to create an exam that is however-long we made it as we took it!) If you went farther than the class’s average attempted number, then you could score some extra points (if you get the answers right, of course) to offset any wrong answers you had along the way. A lot of work to shuffle it every year, but it was a neat idea.

I think it had always worked because kids just didn’t care enough to think it through. We weren’t told the total number of questions, nor what previous classes had attempted. But, for discussion here, let’s say the class’s average-attempted is 200. And let’s say I were to answer 227 questions, but I get 24 wrong. That feels like an 89%, right? No, actually I end up with 203 correct answers, which is more than the class’s average-attempted of 200. I actually score 101.5% and I would get all of the exam’s 500 points towards my semester total. Wait, there’s more: As extra credit, my 3 extra correct answers (my 203 against the 200 attempted average) become extra credit points just added right to my semester total. I’d get 503 points towards my semester!

After the exam was announced, two of my friends and I, realized…

  1. Do not tell another soul about this or everyone will fail the exam.
  2. When you get the test, go as fast as you can. Our goal is to attempt as many questions as possible.
  3. The goal isn’t to get every question right— The goal is to get a lot right.

For example, if we could get just 60% right—normally a really poor performance on an exam—while attempting twice as many as the class average, we win big. Say, 200 average-attempted, against our 400 attempted, at 60% correct (240 correct answers of 400)… we’d score 120% on the exam, plus 40 extra points (our 240 correct above the 200 needed) That’s 540 points towards the semester. And, if we could get 75% correct, while attempting 3 times as many questions, then our exam score is 225% (that’s our 450 correct answers, while needing only 200) plus an extra 250 points (that’s our 450, minus the 200 to ace the exam) That’s 750 points towards the semester! Now do you see the attack? :)

I never understood why no one else ever tried that.

I know this is a minor thing in the universe of problems with secondary education and grading, but I found the hack interesting.

…and I’m actually not sure if what we tried even worked. You thought I was going to have a clear take-away about my actual scores, or the test never being given again?! No the take-away is: Oh, I’ve been thinking like a hacker for a Long. Long. Time.

Upwards

Published October 11, 2023  ·  All posts on Oct 11  ·  

As the edges of human knowledge are advanced, the total amount one must learn to be able to then contribute to further advancement grows. If there’s a proverbial mountain of knowledge, it grows taller as each contributor adds. If you start from the beach (at birth), wander inland in your early years of not-guided-by-you learning, and eventually decide to scale the mountain… well, it really matters in what epoch you happened to be born. Or maybe it doesn’t?

There is a growing mountain of research. But there is increased evidence that we are being bogged down today as specialization extends. The investigator is staggered by the findings and conclusions of thousands of other workers-conclusions which he cannot find time to grasp, much less to remember, as they appear. Yet specialization becomes increasingly necessary for progress, and the effort to bridge between disciplines is correspondingly superficial.

~ Vannevar Bush from, As We May Think

Bush played a complex role in the history of the United States. (It’s better if you form your own opinion about him and his work.) His short essay from about 80 years ago is these days seen by technophiles as heralding our own, current Internet and information age. In particular, a lot is read into Bush’s description of a desk which behaves like our modern Internet, information systems, and data processing. That’s fine. It’s like reading 80-year-old science fiction that became science fact.

Much more interesting to me is the point that with just a bit of squinting, it looks like nothing has changed in 80 years. Everything about this—the mountain of information, the tools [eg, Bush’s imagined desk, our internet], the people feeling overloaded, the specialization—feels fractal.

Curated and random

Published October 9, 2023  ·  All posts on Oct 9  ·  

I recall a little sign which was sometimes spotted on desks, back in the before-times when everyone had a desk and papers and ring-binders and books and a telephone that also sat upon that desk. The sign was: “A messy desk is a sign of genius.” (And sometimes it said, “…of a creative mind.” )

I’ve had a lot of desks. In every case, I’ve always swerved repeatedly between messy and organized. I get to a point where—sometimes with a literal scream—I stop working and reorganize everything. For a long time, I hoped that one day I would manage to be just comfortable enough, with just the right amount of clutter and chaos, to be able to reach a steady state.

One detail that drives me bonkers is in the digital realm, computers are perfectly organized. I use a tool (called Reeder) to manage a read-this-later collection. It’s a big collection often reaching 500 different things marked as possibly interesting. (Some are interesting enough to spend a few minutes on, some are interesting enough to spend hours on.) Sometimes I’ll randomly shuffle things in a digital list. But sometimes… the list is just ordered the way you assemble it. And you can look at the list in forward or reverse order. This gets to me. If it’s a big list, neither forwards or backwards is best. So instead, I do both: I read the item off one end (the thing that’s been in the list longest) and then the other (the newest), and I just alternate in a reading session.

Perhaps this seems like a silly or trivial thing to point out. But there’s a bigger lesson: Where do I have some specific structure (organization, ordering, etc.) that I didn’t actually intend? …is that structure holding me back or keeping me from experiencing something I’d prefer?

Driven a little mad

Published October 9, 2023  ·  All posts on Oct 9  ·  

Reading is letting someone else model the world for you. This is an act of intimacy. When the author is morose, you become morose. When he is mirthful, eventually you may share it. And after finishing a very good book one is driven a little mad, forced to return from a world that no one nearby has witnessed.

Festina lente

Published October 8, 2023  ·  All posts on Oct 8  ·  

Festina lenta is a phrase I once used as my touchstone for a year. It means, to make haste s l o w l y. It’s inherently ridiculous, but also points to the very old and very excellent point about taking one’s time. It’s an antidote to the venoms busy and hurry. “These days” things are not simply faster, they are glossed over. The super-power I need to cultivate more is discrimination: What experiences are valuable? What pursuits are valuable? There’s [almost] always a faster way… but which is the better way?

In that spirit, consider the two paradigms that follow, not as you would two spirited debaters but rather two paintings hanging at opposite ends of a gallery. You are in the middle, bathed in natural light, forced by history to judge their color and attraction.

An agreeable tour

What indeed

While there’s nothing wrong with always having our nose to the grindstone, and having every day feel the same as the last … what would it be like to open to something different?

I hate to quibble with Babauta (his writing having been so instrumental in my growth over decades). But… uhm, actually, I’m going to say there is indeed something wrong with having one’s nose to the grindstone. Working a hard dash on meaningful work is healthy. Dashing all the time is—by definition—not dashing. Lately I’m again and again (and again and again and again) returning to the same problem. I’ve so many things I want to do, but only so many hours.

Why with Dave Closson

Why – with Dave Closson

What processes and mindsets can individuals adopt to clarify their purpose, improve decision-making, and enhance their effectiveness in both personal and professional contexts?

Decision fatigue and productivity, discipline as a path to freedom, and self-reflection.

Better and better and more efficient and more effective, that’s great. It’s about continuous improvement. But I’ve discovered that it’s not just about getting better at what you do, it’s also about getting smarter about how you do it. That’s where the real freedom comes from. It’s like having a well-oiled machine that runs smoothly, and you don’t have to constantly tinker with it.

~ Dave Closson around 17:16

Craig Constantine and Dave Closson begin with finding one’s “why” and how it drives one’s actions and decisions. They stress that articulating a clear why-statement is key to staying focused and avoiding distractions. The conversation shifts to the role of processes and structure, with both speakers emphasizing that they can be liberating rather than constricting, as they help eliminate decision fatigue. Dave introduces the idea of having meaningful conversations with oneself as a way to navigate complex thoughts and emotions effectively.

Takeaways

The Significance of a Clear “Why” — The importance of having a well-defined purpose or “why” in various aspects of life.

Processes and Structures for Efficiency — Contrary to the notion that processes and structures stifle creativity, their role in providing freedom and reducing decision fatigue is highlighted.

Structured Self-Conversations — Dave introduces the concept of structured self-conversations, a valuable tool for introspection and problem-solving.

Continuous Improvement — The conversation touches on the idea that striving for continuous improvement is not just about getting better at what you do but also getting smarter about how you do it.

Balancing Structure and Flexibility — While processes and structures are valuable, it’s essential to strike a balance between structure and flexibility.

Importance of Restorative Practices — The conversation briefly touches on the significance of restorative practices.

Test in the kitchen

Published October 5, 2023  ·  All posts on Oct 5  ·  

Sausages sautéed with potatoes and onions! It’s also highly advisable to have a philosopher or two on hand. A few pages of Plato while working on a baked ham. Wittgenstein’s Tractatus over a bowl of spaghetti with littleneck clams. We think best when we bring opposites together, when we realize that all these realities, one inside the other, are somehow connected. That’s how the wonder and amazement that are so necessary to both poetry and philosophy come about. A “truth” detached and purified of pleasures of ordinary life is not worth a damn in my view. Every grand theory and noble sentiment ought to be first tested in the kitchen—and then in bed, of course.

Part two

Published October 4, 2023  ·  All posts on Oct 4  ·  

It’s time to accept that I’m definitely in part two of my life. I’m done pretending that living to 100 is realistic. (Although, I’m open to being surprised.)

Now on my Artist’s Journey I barely drive to the grocery store.

~ Steven Pressfield from, Writing Wednesdays: After the Wilderness

The thought rattling around in my head is: What are the differences between parts one and two? And I think the central thematic difference is activity versus passivity. In part one the hero expended tremendous effort bashing their way towards the objective. In part two the hero has realized it’s time to play a supporting role.

Bias

Published October 2, 2023  ·  All posts on Oct 2  ·  

These stories illustrate two truths. 1) I’m a big ol’ nerd, and 2) the goodness and badness of memories fade over time, but the badness fades faster—that’s the fading affect bias. Some bad memories even become good memories, while good memories rarely become bad memories.

~ Adam Mastroianni from, Underrated ideas in psychology – by Adam Mastroianni

slip:4ueepu1.

Like Mastroianni, I’m clearly susceptible to this bias. One thing that I use to fight it, is to write myself honest thoughts after things happen. A lot of the pleasure from something is the anticipation—the imagining of the enjoyment from some expected experience. That’s pretty easy to remember to journal and it happens without effort in the days leading up. But after the fact, I usually take a big chunk of time and decompress. What did I really think when I got hit in the head that one time at that thing? …or when I fell? …or got sick? The best adventures are when I look back and think: “ugh, that sucked. I’m glad I did it.”
