Churchill’s D-Day Task List

Last week, I received an email from a reader who had just returned from a trip to the Churchill War Rooms, a London museum housed in the bunkers, built underneath the Treasury Building, where Winston Churchill safely commanded the British war efforts as the Blitz bombarded the city above.

The reader had photographed an artifact he thought I might find interesting: a to-do list labeled “D Day,” written by one of the secretaries serving Churchill.

Here’s a detail shot:

Superficially, I was intrigued because I’ve been consuming a lot of WWII history recently. (At the moment, I’m concurrently reading The Splendid and the Vile along with David Roll’s excellent new George Marshall biography.)

But it also resonated at a deeper level.

On the Neurochemistry of Deep Work

Andrew Huberman is a neurobiologist at Stanford Medical School. His lab specializes in neuroplasticity, the process by which the human brain changes its neuronal connections.

A reader recently brought to my attention a fascinating discussion about learning. It’s from a podcast episode Huberman recorded with Joe Rogan back in July.

Around the two minute mark of the clip, Rogan provides Huberman with a hypothetical scenario: “You’re 35, and want to learn a new skill, what is the best way to set these patterns?”

As someone who is in my thirties and makes a living learning hard things, I was, as you might imagine, interested to hear what Dr. Huberman had to say on this issue. Which is all to preface that I was gratified to hear the following reply:

Do Smartphones Make Us Dumber?

A reader recently pointed me toward an intriguing article published in 2017 in the Journal for the Association of Consumer Research. It was titled, “Brain Drain: The Mere Presence of One’s Own Smartphone Reduces Available Cognitive Capacity.”

The authors of the paper report the results of a straightforward experiment. Subjects are invited into a laboratory to participate in some assessment exercises. Before commencing, however, they’re asked to put their phones away. Some subjects are asked to place their phone on the desk next to the computer on which they’re working; some are told to put their phone in their bag; some are told to put their phone in the other room. (The experimenters had clever ways of manipulating these conditions without arousing suspicion.)

Eric Posner Thinks It’s a “Serious Mistake” for Law Professors to Use Twitter

Eric Posner is arguably one of the most influential and prolific law professors in the country at the moment. Which is why I paid attention when around the 39 minute mark of a recent interview, Posner was asked his thoughts on law professors using Twitter.

“I’ve thought about this a lot because it now seems like every law professor wants to have this public presence,” Posner replied. “And I increasingly think this is a serious mistake.”

As he elaborates, becoming a “good” academic who is “serious” about research is a hard job:

“It requires a huge amount of work, especially at the beginning, to absorb the literature, to absorb the norms…I think a lot of junior people who are on Twitter…should be educating themselves.”

As he then clarifies, most of what transpires on Twitter is people “ranting” and reading other peoples’ “rants.” Participating in that culture, he says, doesn’t contribute in a meaningful way to the public debate.

The interviewer then presents Posner with another standard argument for why academics should engage with social media: it’s a way to “establish prominence in a field or establish name recognition.”

Posner doesn’t buy it:

Focus Week: Rediscover Depth

When I was a young graduate student at MIT, I was impressed by Alan Lightman, a one-time physicist, who turned toward essay and novel writing and ended up accepting a humanities professorship and starting the school’s science journalism program.

What initially caught my attention about Lightman was the following line, which to this day remains defiantly perched at the top of his academic homepage:

“I do not use e-mail, but you can reach me at my MIT office: [mailing address]”

But what really captured my imagination was when I heard about Lightman’s island.

In his late 30’s, at a time when the was looking for a quiet place for him to write and his wife to paint, Lightman stumbled across a 30-acre island in Casco Bay, Maine, shared by six families. There are no bridges or ferries servicing the island; no electricity; no plumbing; no internet or phone. Lightman and his wife spend their summers at this isolated outpost decompressing and creating.

“The world is moving at much too fast a pace: everybody is plugged in 24/7, everything is rush rush rush,” he said in a recent interview. “The island in the summer is a place where we can unplug, slow down, listen to ourselves think.”

I was reminded of Lightman while recently reading about Mary Somerville, the 19th century polymath who was among the first women to be elected to the Royal Astronomical Society. As Somerville recalls in her autobiography, as a child, she would find ways to evade the chores and social activities that defined the lives of women of her social station to instead explore the nearby sea coast:

“When the tide was out I spent hours on the sands…I made collections of shells, such as were cast ashore, some so small that they appeared like white specks in patches of black sand. There was a small pier on the sands for shipping limestone brought from the coal mines inland. I was astonished to see the surface of these blocks of stone covered with beautiful impressions of what seemed to be leaves; how they got there I could not imagine, but I picked up the broken bits, and even large pieces, and brought them to my repository.”

Her collection, begun during those childhood expeditions, is now housed at the college named in her honor at the University of Oxford.

Lightman and Somerville’s lives were defined and elevated by regular exposure to depth: extended periods of undistracted time during which the mind can focus intensely on one thing, or purposefully on nothing at all. In both cases, this depth was hard-won. Lightman’s island was remote and offered primitive living conditions. He had never used a boat before committing to a house that required one to access. Somerville, for her part, had to battle the gender expectations of her era to carve out a deeper life. It never came easy.

But they invested the effort because, as I argue in Deep Work, we can find evidence from psychology, neuroscience, philosophy and theology that all supports the same conclusion: humans thrive on concentration and presence.

Which brings us to the last five months: a period in which such moments of depth were lost to the daily waves of anxiety and uncertainty.

In my previous Focus Week essay, I recommended unplugging to provide your brain some breathing room. Here I’m recommending that you put this breathing room to good use by reintroducing yourself to the pleasures of concentrating without distraction on something difficult but rewarding; to rediscover, in other words, the necessity of depth.
