The value of owning more books than you can read
Or, how I learned to stop worrying and love my tsundoku.

- Many readers buy books with every intention of reading them only to let them linger on the shelf.
- Statistician Nassim Nicholas Taleb believes surrounding ourselves with unread books enriches our lives as they remind us of all we don't know.
- The Japanese call this practice tsundoku, and it may provide lasting benefits.
I love books. If I go to the bookstore to check a price, I walk out with three books I probably didn't know existed beforehand. I buy second-hand books by the bagful at the Friends of the Library sale, while explaining to my wife that it's for a good cause. Even the smell of books grips me, that faint aroma of earthy vanilla that wafts up at you when you flip a page.
The problem is that my book-buying habit outpaces my ability to read them. This leads to FOMO and occasional pangs of guilt over the unread volumes spilling across my shelves. Sound familiar?
But it's possible this guilt is entirely misplaced. According to statistician Nassim Nicholas Taleb, these unread volumes represent what he calls an "antilibrary," and he believes our antilibraries aren't signs of intellectual failings. Quite the opposite.
Living with an antilibrary

Taleb laid out the concept of the antilibrary in his best-selling book The Black Swan: The Impact of the Highly Improbable. He starts with a discussion of the prolific author and scholar Umberto Eco, whose personal library housed a staggering 30,000 books.
When Eco hosted visitors, many would marvel at the size of his library and assumed it represented the host's knowledge — which, make no mistake, was expansive. But a few savvy visitors realized the truth: Eco's library wasn't voluminous because he had read so much; it was voluminous because he desired to read so much more.
Eco stated as much. Doing a back-of-the-envelope calculation, he found he could only read about 25,200 books if he read one book a day, every day, between the ages of ten and eighty. A "trifle," he laments, compared to the million books available at any good library.
Drawing from Eco's example, Taleb deduces:
Read books are far less valuable than unread ones. [Your] library should contain as much of what you do not know as your financial means, mortgage rates, and the currently tight real-estate market allows you to put there. You will accumulate more knowledge and more books as you grow older, and the growing number of unread books on the shelves will look at you menacingly. Indeed, the more you know, the larger the rows of unread books. Let us call this collection of unread books an antilibrary. [Emphasis original]
Maria Popova, whose post at Brain Pickings summarizes Taleb's argument beautifully, notes that our tendency is to overestimate the value of what we know, while underestimating the value of what we don't know. Taleb's antilibrary flips this tendency on its head.
The antilibrary's value stems from how it challenges our self-estimation by providing a constant, niggling reminder of all we don't know. The titles lining my own home remind me that I know little to nothing about cryptography, the evolution of feathers, Italian folklore, illicit drug use in the Third Reich, and whatever entomophagy is. (Don't spoil it; I want to be surprised.)
"We tend to treat our knowledge as personal property to be protected and defended," Taleb writes. "It is an ornament that allows us to rise in the pecking order. So this tendency to offend Eco's library sensibility by focusing on the known is a human bias that extends to our mental operations."
These selves of unexplored ideas propel us to continue reading, continue learning, and never be comfortable that we know enough. Jessica Stillman calls this realization intellectual humility.
People who lack this intellectual humility — those without a yearning to acquire new books or visit their local library — may enjoy a sense of pride at having conquered their personal collection, but such a library provides all the use of a wall-mounted trophy. It becomes an "ego-booting appendage" for decoration alone. Not a living, growing resource we can learn from until we are 80 — and, if we are lucky, a few years beyond.
Tsundoku

I love Taleb's concept, but I must admit I find the label "antilibrary" a bit lacking. For me, it sounds like a plot device in a knockoff Dan Brown novel — "Quick! We have to stop the Illuminati before they use the antilibrary to erase all the books in existence."
Writing for the New York Times, Kevin Mims also doesn't care for Taleb's label. Thankfully, his objection is a bit more practical: "I don't really like Taleb's term 'antilibrary.' A library is a collection of books, many of which remain unread for long periods of time. I don't see how that differs from an antilibrary."
His preferred label is a loanword from Japan: tsundoku. Tsundoku is the Japanese word for the stack(s) of books you've purchased but haven't read. Its morphology combines tsunde-oku (letting things pile up) and dukosho (reading books).
The word originated in the late 19th century as a satirical jab at teachers who owned books but didn't read them. While that is opposite of Taleb's point, today the word carries no stigma in Japanese culture. It's also differs from bibliomania, which is the obsessive collecting of books for the sake of the collection, not their eventual reading.
The value of tsundoku
Granted, I'm sure there is some braggadocious bibliomaniac out there who owns a collection comparable to a small national library, yet rarely cracks a cover. Even so, studies have shown that book ownership and reading typically go hand in hand to great effect.
One such study found that children who grew up in homes with between 80 and 350 books showed improved literacy, numeracy, and information communication technology skills as adults. Exposure to books, the researchers suggested, boosts these cognitive abilities by making reading a part of life's routines and practices.
Many other studies have shown reading habits relay a bevy of benefits. They suggest reading can reduce stress, satisfy social connection needs, bolster social skills and empathy, and boost certain cognitive skills. And that's just fiction! Reading nonfiction is correlated with success and high achievement, helps us better understand ourselves and the world, and gives you the edge come trivia night.
In her article, Jessica Stillman ponders whether the antilibrary acts as a counter to the Dunning-Kruger effect, a cognitive bias that leads ignorant people to assume their knowledge or abilities are more proficient than they truly are. Since people are not prone to enjoying reminders of their ignorance, their unread books push them toward, if not mastery, then at least a ever-expanding understanding of competence.
"All those books you haven't read are indeed a sign of your ignorance. But if you know how ignorant you are, you're way ahead of the vast majority of other people," Stillman writes.
Whether you prefer the term antilibrary, tsundoku, or something else entirely, the value of an unread book is its power to get you to read it.

‘Designer baby’ book trilogy explores the moral dilemmas humans may soon create
How would the ability to genetically customize children change society? Sci-fi author Eugene Clark explores the future on our horizon in Volume I of the "Genetic Pressure" series.
- A new sci-fi book series called "Genetic Pressure" explores the scientific and moral implications of a world with a burgeoning designer baby industry.
- It's currently illegal to implant genetically edited human embryos in most nations, but designer babies may someday become widespread.
- While gene-editing technology could help humans eliminate genetic diseases, some in the scientific community fear it may also usher in a new era of eugenics.
Tribalism and discrimination
<p>One question the "Genetic Pressure" series explores: What would tribalism and discrimination look like in a world with designer babies? As designer babies grow up, they could be noticeably different from other people, potentially being smarter, more attractive and healthier. This could breed resentment between the groups—as it does in the series.</p><p>"[Designer babies] slowly find that 'everyone else,' and even their own parents, becomes less and less tolerable," author Eugene Clark told Big Think. "Meanwhile, everyone else slowly feels threatened by the designer babies."</p><p>For example, one character in the series who was born a designer baby faces discrimination and harassment from "normal people"—they call her "soulless" and say she was "made in a factory," a "consumer product." </p><p>Would such divisions emerge in the real world? The answer may depend on who's able to afford designer baby services. If it's only the ultra-wealthy, then it's easy to imagine how being a designer baby could be seen by society as a kind of hyper-privilege, which designer babies would have to reckon with. </p><p>Even if people from all socioeconomic backgrounds can someday afford designer babies, people born designer babies may struggle with tough existential questions: Can they ever take full credit for things they achieve, or were they born with an unfair advantage? To what extent should they spend their lives helping the less fortunate? </p>Sexuality dilemmas
<p>Sexuality presents another set of thorny questions. If a designer baby industry someday allows people to optimize humans for attractiveness, designer babies could grow up to find themselves surrounded by ultra-attractive people. That may not sound like a big problem.</p><p>But consider that, if designer babies someday become the standard way to have children, there'd necessarily be a years-long gap in which only some people are having designer babies. Meanwhile, the rest of society would be having children the old-fashioned way. So, in terms of attractiveness, society could see increasingly apparent disparities in physical appearances between the two groups. "Normal people" could begin to seem increasingly ugly.</p><p>But ultra-attractive people who were born designer babies could face problems, too. One could be the loss of body image. </p><p>When designer babies grow up in the "Genetic Pressure" series, men look like all the other men, and women look like all the other women. This homogeneity of physical appearance occurs because parents of designer babies start following trends, all choosing similar traits for their children: tall, athletic build, olive skin, etc. </p><p>Sure, facial traits remain relatively unique, but everyone's more or less equally attractive. And this causes strange changes to sexual preferences.</p><p>"In a society of sexual equals, they start looking for other differentiators," he said, noting that violet-colored eyes become a rare trait that genetically engineered humans find especially attractive in the series.</p><p>But what about sexual relationships between genetically engineered humans and "normal" people? In the "Genetic Pressure" series, many "normal" people want to have kids with (or at least have sex with) genetically engineered humans. But a minority of engineered humans oppose breeding with "normal" people, and this leads to an ideology that considers engineered humans to be racially supreme. </p>Regulating designer babies
<p>On a policy level, there are many open questions about how governments might legislate a world with designer babies. But it's not totally new territory, considering the West's dark history of eugenics experiments.</p><p>In the 20th century, the U.S. conducted multiple eugenics programs, including immigration restrictions based on genetic inferiority and forced sterilizations. In 1927, for example, the Supreme Court ruled that forcibly sterilizing the mentally handicapped didn't violate the Constitution. Supreme Court Justice Oliver Wendall Holmes wrote, "… three generations of imbeciles are enough." </p><p>After the Holocaust, eugenics programs became increasingly taboo and regulated in the U.S. (though some states continued forced sterilizations <a href="https://www.uvm.edu/~lkaelber/eugenics/" target="_blank">into the 1970s</a>). In recent years, some policymakers and scientists have expressed concerns about how gene-editing technologies could reanimate the eugenics nightmares of the 20th century. </p><p>Currently, the U.S. doesn't explicitly ban human germline genetic editing on the federal level, but a combination of laws effectively render it <a href="https://academic.oup.com/jlb/advance-article/doi/10.1093/jlb/lsaa006/5841599#204481018" target="_blank" rel="noopener noreferrer">illegal to implant a genetically modified embryo</a>. Part of the reason is that scientists still aren't sure of the unintended consequences of new gene-editing technologies. </p><p>But there are also concerns that these technologies could usher in a new era of eugenics. After all, the function of a designer baby industry, like the one in the "Genetic Pressure" series, wouldn't necessarily be limited to eliminating genetic diseases; it could also work to increase the occurrence of "desirable" traits. </p><p>If the industry did that, it'd effectively signal that the <em>opposites of those traits are undesirable. </em>As the International Bioethics Committee <a href="https://academic.oup.com/jlb/advance-article/doi/10.1093/jlb/lsaa006/5841599#204481018" target="_blank" rel="noopener noreferrer">wrote</a>, this would "jeopardize the inherent and therefore equal dignity of all human beings and renew eugenics, disguised as the fulfillment of the wish for a better, improved life."</p><p><em>"Genetic Pressure Volume I: Baby Steps"</em><em> by Eugene Clark is <a href="http://bigth.ink/38VhJn3" target="_blank">available now.</a></em></p>Designer uses AI to bring 54 Roman emperors to life
It's hard to stop looking back and forth between these faces and the busts they came from.
Meet Emperors Augustus, left, and Maximinus Thrax, right

<p>Voshart's imaginings began with an AI/neural-net program called <a href="https://www.artbreeder.com" target="_blank">Artbreeder</a>. The freemium online app intelligently generates new images from existing ones and can combine multiple images into…well, who knows. It's addictive — people have so far used it to generate nearly 72.7 million images, says the site — and it's easy to see how Voshart fell down the rabbit hole.</p><p>The Roman emperor project began with Voshart feeding Artbreeder images of 800 busts. Obviously, not all busts have weathered the centuries equally. Voshart told <a href="https://www.livescience.com/ai-roman-emperor-portraits.html" target="_blank" rel="noopener noreferrer">Live Science</a>, "There is a rule of thumb in computer programming called 'garbage in garbage out,' and it applies to Artbreeder. A well-lit, well-sculpted bust with little damage and standard face features is going to be quite easy to get a result." Fortunately, there were multiple busts for some of the emperors, and different angles of busts captured in different photographs.</p><p>For the renderings Artbreeder produced, each face required some 15-16 hours of additional input from Voshart, who was left to deduce/guess such details as hair and skin coloring, though in many cases, an individual's features suggested likely pigmentations. Voshart was also aided by written descriptions of some of the rulers.</p><p>There's no way to know for sure how frequently Voshart's guesses hit their marks. It is obviously the case, though, that his interpretations look incredibly plausible when you compare one of his emperors to the sculpture(s) from which it was derived.</p><p>For an in-depth description of Voshart's process, check out his posts on <a href="https://medium.com/@voshart/photoreal-roman-emperor-project-236be7f06c8f" target="_blank">Medium</a> or on his <a href="https://voshart.com/ROMAN-EMPEROR-PROJECT" target="_blank" rel="noopener noreferrer">website</a>.</p><p>It's fascinating to feel like you're face-to-face with these ancient and sometimes notorious figures.

<p><span style="background-color: initial;"><a href="https://en.wikipedia.org/wiki/Caligula" target="_blank">Caligula</a></span> was the third Roman Emperor, ruling the city-state from AD 37 to 41. His name was actually Gaius Caesar Augustus Germanicus — Caligula is a nickname meaning "Little Boot."</p><p>One of the reputed great madmen of history, he was said to have made a horse his consul, had conversations with the moon, and to have ravaged his way through his kingdom, including his three sisters. Caligula is known for extreme cruelty, terrorizing his subjects, and accounts suggest he would deliberately distort his face to surprise and frighten people he wished to intimidate.</p><p>It's <a href="https://www.history.com/news/7-things-you-may-not-know-about-caligula" target="_blank">not totally clear</a> if Caligula was as over-the-top as history paints him, but that hasn't stopped Hollywood from churning out some <a href="https://www.imdb.com/title/tt0080491/" target="_blank" rel="noopener noreferrer">howlers</a> in his name.</p><p>A 1928 journal, <a href="https://www.jstor.org/stable/4172009" target="_blank">Studies in Philology</a>, noted that contemporary descriptions of Caligula depicted him as having a "head misshapen, eyes and temples sunken," and "eyes staring and with a glare savage enough to torture." In some sculptures not shown above, his head <em>is</em> a bit acorn-shaped. </p>Nero

<p>There's a good German word for the face of <a href="https://en.wikipedia.org/wiki/Nero" target="_blank" rel="noopener noreferrer">Nero</a>, that guy famous for fiddling as Rome burned. It's "<a href="https://www.urbandictionary.com/define.php?term=Backpfeifengesicht" target="_blank">backpfeifengesicht</a>." Properly named Nero Claudius Caesar Augustus Germanicus, he was Rome's fifth emperor. He ruled from AD 54 until his suicide in AD 68.</p><p>Another Germanicus-family gem, Nero's said to have murdered his own mother, Agrippa, as well as (maybe) his second wife. As for the fiddling, he <em>was</em> a lover of music and the arts, and there are stories of his charitability. And, oh yeah, he may have set the fire as an excuse to rebuild the city center, making it his own.</p><p>While it may not be the most historically sound means of assessing an historical personage, Voshart's imagining of Nero does suggest an over-indulged, entitled young man. Backpfeifengesicht.</p>This is your brain on political arguments

<p>Leading us to an interesting question: do the same brain regions fire when you're screaming with your fingers on your Facebook feed? Given the lack of visual feedback from the person on the other side of the argument, likely not—as it is unlikely that many people would argue in the same manner when face-to-face with a person on the other side of a debate. We are generally more civil in real life than on a screen.</p><p>The researchers point out that seeing faces causes complex neurological reactions that must be interpreted in real-time. For example, gazing into someone's eyes requires higher-order processing that must be dealt with during the moment. Your brain coordinates to make sense of the words being spoken <em>and</em> pantomimes being witnessed. This combination of verbal and visual processes are "generally associated with high-level cognitive and linguistic functions."</p><p>While arguing is more exhausting, it also sharpens your senses—when a person is present, at least. Debating is a healthy function of society. Arguments force you to consider other viewpoints and potentially come to different conclusions. As with physical exercise, which makes you stronger even though it's energetically taxing, disagreement propels societies forward.</p>In this study, every participant was forced to <em>listen</em> to the other person. As this research was focused on live interactions, it adds to the literature of cognitive processing during live interactions and offers insights into the cognitive tax of anger. Even anger is a net positive when it forces both sides to think through their thoughts and feelings on a matter. As social animals, we need that tension in our lives in order to grow.

<p>For <a href="https://data.giss.nasa.gov/gistemp/" target="_blank">its 2020 analysis</a>, NASA gathered surface temperature measurements from more than 26,000 weather stations. This data was incorporated with data from satellites as well as sea-surface temperatures taken from ship and buoy instruments. Once tallied, NASA's data showed 2020 barely edged out 2016 as the warmest year on record, with average global temperatures 1.02°C (1.84°F) above the baseline mean (1951-1980).</p><p>In a separate analysis of the raw data, NOAA found 2020 to be slightly cooler than 2016. This distinction is the result of the different methodologies used in each—for example, NOAA uses a different baseline period (1901–2000) and does not infer temperatures in polar regions lacking observations. Together, these analyses put 2020 in a statistical dead heat with the sweltering 2016 and demonstrate the global-warming trend of the past four decades.</p><p>"The last seven years have been the warmest seven years on record, typifying the ongoing and dramatic warming trend," <a href="http://email.prnewswire.com/ls/click?upn=OXp-2BEvHp8OzhyU1j9bSWuwMvMWelqIco5RbfBrouY-2BQCsSv6FnrhBjR9xReGqV57KGOs0rVc5GKMmgs-2FJKbOzjb0sJ6yjzUvrv2w75ulYk3EUck8pSjkzYhoy5ADXO0eOcn7LDjqsHyK2gp2NRf2UysMK-2F9SN4oYUmRylQcRtSUo6-2FcYeK-2B9naUetByXNCR2gF8u_FU3lc-2FvIcVOtjb4iEuBVjFYoW0IRF5dtM-2FDfzzkhmYHO5IVgq387-2BxdHEMunBZ1-2Fy0-2BJDgXnZEYvN604G1TWJfy4M4HKnIouyasgRyWEHIYmPTiDXeFrd9FqRmsl0JQfksEElkp2ITvgyFkkivWV3GiFH7z7tl1cTZ2rNh2c-2FbCRKQxkH4-2BChgYT6uWeYOvXusiC4cDsZkEBvw7lOEdPsPq78JT8F5x5gc5cMRaRJY-2FZ8q8peaKsS7Mfc5OQ6yjyEU5YUHR4QKJ1Fn-2FDuwJ5jk4Gm28sxJZNXX9IEO-2FOHlhyRcJbl6rMWcoeJZDEd-2BM8UJ5ZY-2FYqc1DHevd1Mz-2B1fQ-3D-3D" target="_blank">Gavin Schmidt</a>, director of the NASA Goddard Institute for Space Studies, <a href="https://www.sciencedaily.com/releases/2021/01/210115103020.htm" target="_blank" rel="noopener noreferrer">said in a release</a>.

According to the analyses, 2020 was the warmest year on record for Asia and Europe, the second warmest for South America, the fourth warmest for Africa and Australia, and the tenth warmest for North America. </p><p>All told, 2020 was 1.19°C (2.14°F) above averages from the late-19<sup>th</sup> century, a period that provides a rough approximate for pre-industrial conditions. This temperature is closing in on the Paris Climate Agreement's preferred goal of <a href="https://unfccc.int/process-and-meetings/the-paris-agreement/the-paris-agreemen" target="_blank" rel="noopener noreferrer">limiting global warming to 1.5°C</a> of those pre-industrial conditions.</p>2020's hotspot was—the Arctic?

<p>Heatwaves have become more common all over the world, but a region that really endured the heat in 2020 was the <a href="https://nsidc.org/cryosphere/arctic-meteorology/climate_change.html#:~:text=Over%20the%20past%2030%20years,climate%20change%20in%20the%20Arctic." target="_blank">Arctic</a>.</p><p>"The big story this year is Siberia; it was a hotspot," Russell Vose, chief of the analysis and synthesis branch of NOAA's National Centers for Environmental Information, said during the briefing. "In May, some places were 18°F above the average. There was a town in Siberia […] that reported a high temperature of 104°F. If that gets verified by the World Metrological Organization, it will the first there's been a weather station in the Arctic with a temperature above 100°F."</p><p>The Arctic is warming at three times the global mean, thanks to <a href="https://nsidc.org/cryosphere/arctic-meteorology/climate_change.html#:~:text=Over%20the%20past%2030%20years,climate%20change%20in%20the%20Arctic." target="_blank">a phenomenon known as Arctic Amplification</a>. As the Arctic warms, it loses its sea ice, and this creates a feedback loop. The more Arctic sea ice loss, the more heat introduced into the oceans; the more heat introduced, the more sea ice loss. And the longer this trend continues, the more devastating the effects.</p><p>For example, since the 1980s, there's been a 50 percent decline in sea ice, and this loss has exposed more of the ocean to the sun's rays. That energy then gets trapped in the ocean as heat. As the <a href="https://www.climate.gov/news-features/understanding-climate/climate-change-ocean-heat-content" target="_blank" rel="noopener noreferrer">ocean heat content</a> rises, it threatens rising sea levels and the sustainability of natural ecosystems. In 2020 alone, 255 zeta joules of heat above the baseline were introduced into Earth's oceans. In (admittedly) dramatic terms, that's <a href="https://www.mprnews.org/story/2020/01/14/twin-cities-scientist-heat-of-5-to-6-hiroshima-atom-bombs-per-second-into-earths-oceans" target="_blank" rel="noopener noreferrer">the equivalent of introducing 5 to 6 Hiroshima atom bombs</a> worth of energy every second of every day.</p><p>Looking beyond the Arctic, the average snow cover for the Northern Hemisphere was also the lowest on record. Like the Arctic sea ices, such <a href="https://nsidc.org/cryosphere/snow/climate.html#:~:text=Snow's%20effect%20on%20climate,especially%20the%20western%20United%20States." target="_blank" rel="noopener noreferrer">snow cover</a> helps regulate Earth's surface temperatures. Its melt off in the spring and summer also provides the freshwater ecosystems rely on to survive and farmers need to grow crops, especially in <a href="https://bigthink.com/surprising-science/too-many-trees?rebelltitem=2#rebelltitem2" target="_self">the Western United States</a>.</p>Natural disasters get a man-made bump

<p>2020 was also a record-breaking year for natural disasters. In the U.S. alone, there were 22 billion-dollar disasters, the most ever recorded. Combined, they resulted in a total of $95 billion in losses. The western wildfires alone consumed more than 10 million acres and destroyed large portions of Oregon, Colorado, and California.</p><p>The year also witnessed a record-setting Atlantic Hurricane season with more than 30 named storms, 13 of which were hurricanes. Typically, the World Meteorological Organization <a href="https://www.nhc.noaa.gov/aboutnames_history.shtml#:~:text=Instead%20a%20strict%20procedure%20has,is%20repeated%20every%20sixth%20year." target="_blank">names storms</a> from an annual list of 21 selected names—one for each letter of the alphabet, minus Q, U, X, Y, and Z. For only <a href="https://www.npr.org/2020/09/18/914453403/so-2020-new-storm-forms-named-alpha-because-weve-run-out-of-letters" target="_blank" rel="noopener noreferrer">the second time in history</a>, the Organization had to resort to naming storms after Greek letters because they ran out of alphabet.</p>For the record, there's a consensus about the record

They make for an eye-catching headline, sure. But those headlines can sometimes mask the fact that these years are part of decade-long trends, trends providing a preview of what a climate-changed world will be like. </p><p>And in case there was any question as to whether these trends were the result of natural processes or man-made conditions, Schmidt and Vose did not mince words. </p><p>As Schmidt said in the briefing: "Many, many things have caused the climate to change in the past: asteroids, wobbles in the Earth's orbit, moving continents. But when we look at the 20<sup>th</sup> century, we can see very clearly what has been happening. We know the continents have not moved very much, we know the orbit has not changed very much, we know when there were volcanoes, we know what the sun is doing, and we know what we've been doing."</p><p>He continued, "When we do an attribution by driver of climate change over the 20<sup>th</sup> century, what we find is that the overwhelming cause of the warming is the increase of greenhouse gases. When you add in all of the things humans have done, all of the trends over this period are attributable to human activity."</p><p>The data are in; the consensus is in. The only thing left is to figure out how to prevent the worst of climate change before it's too late. As bad as 2020 was, it was only a preview of what could come.<strong></strong></p>Dark matter axions possibly found near Magnificent 7 neutron stars
