evolution is amazing: bats vs. moths

Think about bats and moths. Bats like to eat moths; moths, for obvious reasons, do not like to be eaten.

Bats track their prey using a method called echolocation: they make high pitched sounds (so high pitched that humans can’t hear them) and then judge what’s around them by how the sound bounces back. Moths, to avoid ending up as a tasty snack, evolved ears with the ability to hear these sounds and dive out of the air in response. Bats, in turn, evolved the ability to emit sounds that were even more extreme — much higher or lower frequency — that the moths couldn’t hear. So the moths evolved ears with an expanded hearing range. Bats evolved to lower the volume of their sounds as they closed in on moths. Moths evolved high-frequency clicks that may scramble the bats’ ability to process the echoes they use to locate their food.

It is an evolutionary arms race.

writing may have led to the collapse of the greeks

The interplay between knowledge and power was always a crucial factor in understanding empires.

Innis argued that a balance between the spoken word and writing contributed to the flourishing of ancient Greece in the time of Plato.

This balance between the time-biased medium of speech and the space-biased medium of writing was eventually upset, Innis argued, as the oral tradition gave way to the dominance of writing. The torch of empire then passed from Greece to Rome.

The Brain: Great at pattern recognition but bad at recall

The basic functioning mode of the human mind is not reasoning and planning, but interacting via perception and action with the environmental situation.

While long-term memory is very effective at recognition, it is rather poor at recall, i.e. reviving memory patterns without perceptual stimulation. This is illustrated by the “tip of the tongue” phenomenon, where a fact, such as a colleague’s name, cannot be recalled—even though you know the memory is there.

In that sense, human memory is much less reliable than a computer memory for retrieving a fact outside of the concrete context that reminds you of that fact.

the entire media business is inverting

The entire media business is inverting. For decades, scarce capital and constrained distribution capacity meant that the media’s industry bottlenecks sat in the middle of the value chain. Today, however, the bottleneck has moved to the very end: consumer attention. This shifts the balance of power from determining what should be made to finding a way to convince people what to watch, listen to or read in a world of infinitely abundant content.

people over-estimate their abilities

In psychology, this is known as the Dunning-Kruger effect, or the cognitive bias in which individuals with low ability perceive themselves as having high ability.

Dunning and Kruger found that after gaining a small amount of knowledge in a particular domain, an individual’s confidence soared. However, when that individual was provided with further training, they were better able to asses their skills and their confidence dropped. It was only once their experience approached that of an expert did their confidence rise again.

Jason Zweig, a writer for the Wall Street Journal, found that roughly 75% of people believe they’re above average regardless of the skill that is being assessed. Driving? ~75% believe they are above average. Telling jokes? ~75% above average. Intelligence tests? You guessed it. This was true despite the mathematical fact that only 50% of people can be above average.

marshall mcluhan on advertising

"In the future, people will get huge information satisfaction from ads, far more than they do from the product itself.

Where advertising is heading is quite simply into a world where the ad will become a substitute for the product and all the satisfactions will be derived informationally from the ad and the product will be merely a number in some file somewhere."

problem in higher education

The problems within higher education go far beyond left-leaning bias. 

For example, we rarely give serious consideration to the financial and opportunity costs that young people are burdened with, and how this likely exacerbates economic inequalities. We rarely talk about how universities have abdicated their mission of preserving and transmitting the cultural capital of western civilization.

The elite schools in America seem more invested in being finishing schools for the wealthy than in preserving the integrity of their liberal arts courses.

The rise of small brands

In nearly every consumer sector, small, independent brands are increasingly taking a bite out of larger‑scale players. Between 2013 and 2016 craft breweries went from 9.4% to 12.3% of beer production in the US. Craft alone is no longer cool enough, and in 2016 the smallest guys — microbreweries and brew pubs — drove 90% of craft brew growth.

A similar story has played out in the booming beauty sector, where indie brands were up a staggering 43% in 2016.

how cooking made us human

The advent of cooking enabled humans to eat more kinds of food, to devote less time to eating, and to make do with smaller teeth and shorter intestines. Some scholars believe there is a direct link between the advent of cooking, the shortening of the human intestinal track, and the growth of the human brain. Since long intestines and large brains are both massive energy consumers, it’s hard to have both. By shortening the intestines and decreasing their energy consumption, cooking inadvertently opened the way to the jumbo brains of Neanderthals and Sapiens.

Fire also opened the first significant gulf between man and the other animals… When humans domesticated fire, they gained control of an obedient and potentially limitless force. Unlike eagles, humans could choose when and where to ignite a flame, and they were able to exploit fire for any number of tasks. Most importantly, the power of fire was not limited by the form, structure or strength of the human body. A single woman with a flint or fire stick could burn down an entire forest in a matter of hours. The domestication of fire was a sign of things to come.

apple's new headquarters: the ultimate apple product

The big vision also belonged to Apple’s co-founder Steve Jobs, who first met with Norman Foster in 2009 and was much consumed by Apple Park during the last two years of his life (he passed away in 2011). That vision was of making work as much like a walk in the park as possible. More pragmatically, it was about bringing together a workforce housed in 100 separate buildings, then choreographing levels of integration and collaboration.

Where Infinite Loop, Apple’s previous home, is a sprawl of separate buildings, The Ring is a unified whole. And it would be easy to see this new closed loop as Apple’s culture of secrecy made physical. It’s a culture that Ive is quick to defend. There is no ‘moon shot’ division at Apple, publicly declaring its ambitions to cure cancer or establish a new Eden on Mars. ‘The way that we work is quietly,’ Ive says. ‘We are conspicuously different in that and it is an important part of who we are.’

The building, though, is not a metaphor for open systems, or creative flow made concrete. It is a made object. Apple’s success has been built on higher-order industrialization; not just designing beautiful objects that do all manner of new things but producing them in incredible numbers and at consistent quality. Its new building is, in some ways, the ultimate Apple product, in places using the same materials the company uses in its laptops and phones.

apple retail's unrivaled scale

Apple’s scale is mostly unrivaled. The company booked over $215 billion in overall sales in 2016. More than 25% of these sales came from Apple’s own retail properties, both online and offline, and 75% came from third-party retail, such as phone carriers like Verizon and electronics stores like Best Buy. (In 2017, Apple’s direct sales have grown to 28%, as the company relies more on its own distribution.) 

Out of this 25% of direct sales for 2016, close to 90% of it occurs offline in Apple’s nearly 500 retail stores. That’s about $48 billion total in overall retail sales or $97 million per store. Various market reports say the company pushes over $5,000 per square foot in its stores, with each store averaging around 17,000 square feet. Close to 500 million people visit Apple stores each year, but only 1 out of every 100 buys something, according to former retail head Ron Johnson.

life lessons from sam hinkie

In the short term, investing in that sort of innovation often doesn’t look like much progress, if any. Abraham Lincoln said “give me six hours to chop down a tree and I will spend the first four sharpening the axe.”

Lifelong learning is where it’s at. To walk down that path requires a deep-seated humility about a) what’s knowable, and b) what each of us know. We hire for this aggressively. We celebrate this internally. And we’ve been known to punish when we find it woefully lacking

Howard Marks describes this as a necessary condition of great performance: you have to be non-consensus and right. Both. That means you have to find some way to have a differentiated viewpoint from the masses. And it needs to be right. Anything less won’t work.

If we want to think like a scientist more often in life, those are the three key objectives—to be humbler about what we know, more confident about what’s possible, and less afraid of things that don’t matter.

how online advertising rewards extremism

Because of dynamic pricing and targeting, where things that are more interesting or engaging are fundamentally less expensive to distribute online, there is a tendency for more extreme messages to be cheaper to distribute. So, we might have campaign finance laws and other rules about how much money a candidate can spend, but if one candidate’s extremist message is 20 times less expensive to distribute than another candidate’s centrist views, then the playing field is fundamentally unfair to moderates compared with an earlier world where all ad rates were the same for the same reach on TV and in print.

arguing: The secret to the wright brothers success

When the Wright brothers said they thought together, what they really meant is that they argued together.

One of their pivotal decisions was the design of a propeller for their plane. They squabbled for weeks, often shouting back and forth for hours. “After long arguments we often found ourselves in the ludicrous position of each having been converted to the other’s side,” Orville reflected, “with no more agreement than when the discussion began.”

Only after thoroughly decimating each other’s arguments did it dawn on them that they were both wrong. They needed not one but two propellers, which could be spun in opposite directions to create a kind of rotating wing. “I don’t think they really got mad,” their mechanic marveled, “but they sure got awfully hot.”

brands help people avoid bad outcomes

People bought brands to avoid badness rather than to maximize perfection.

They buy brand A over brand B not because they think it is better, but because they are more certain it is good.

we sleep to forget things

We sleep to forget some of the things we learn each day. In order to learn, we have to grow connections, or synapses, between the neurons in our brains. These connections enable neurons to send signals to one another quickly and efficiently. We store new memories in these networks.

When we sleep, our brains pare back the connections to lift the signal over the noise.

Without nighttime pruning, their memories ended up fuzzy.

business vs. democracy

The point of democracy has never been about having the most efficient form of government. But the best companies are in many respects totalitarian: CEOs have the final say, and employees either get on board or get out. That, though, is only viable because the downside is merely financial; when governments go wrong, on the other hand, far worse can result. That is democracy’s upside: it may not get the most done, but that applies to good outcomes as well as bad.

words: still under-rated

Ideas change the world, particularly when they are written. The Romans built buildings, and the Romans and the buildings are both gone. The Jews wrote a book, and they are still here, and so is the book. So it turns out that words may well last longer than stone, and have more impact than whole empires.

Don’t ever underestimate the power of words. Without them, we would still be living in trees. So when you are writing an essay, you are harnessing the full might of culture to your life.

the power of psychological improvements

The single best thing the London Underground did in terms of improving passenger satisfaction per pound spent wasn't faster, more frequent, later running trains, it was putting dot matrix display boards on the platform to tell you how long you were going to have to wait for your next train.

There's something about the human brain, for whatever reason, which hates uncertainty. That's an interesting case because if you research how can you improve the Underground, most people would have said, "I want faster trains. I want more frequent trains." They would not have said, "I want less uncertainty."

why brands are rational

People pay a premium for brands not because they're objectively better, but because they're less likely to be terrible. 

Whatever you think about McDonald's—it's really, really good at not being bad. If you understand satisficing—which would be another concept hugely important to the understanding of human behavior—we think we maximize and we describe our behavior as if we're maximizing but most of the time we go "I want something that's pretty good and definitely isn't awful." Why do we go to McDonald's? Is it the best food in town? Probably not. The search cost of finding the best place to eat in town, given that we've only got one shot at having a meal in a strange town, would be pretty high. But also when you go into McDonald's you know you're not going to be ripped off, you're almost certainly not going to be ill. By contrast I've become ill after eating at Michelin-Starred restaurants quite frequently. 

Once you understand the perfectly sensible evolutionary instinct to satisfice, then the preference for brands is not irrational at all: I will pay a premium as a form of insurance for the reduced likelihood that this product is appalling.

eastern vs. western thought

The West tends to see purposeful design where the Chinese see spontaneous growth. This is the key to understanding both the strength and weakness of the Western worldview.

One example: creation myths. 

The story told in Genesis is an exemplar of the Western mechanical mindset. God assembles everything piece by piece out of raw materials, very purposefully, then brings Adam to life by breathing into his nostrils. Here God is portrayed as the Celestial Engineer, and the universe, his animatronic invention.

The Chinese, as if to provide a dramatic contrast, have no creation myth. (OK, this is a slight exaggeration, but the gist is true enough.) The Chinese view of the universe is that of spontaneous growth, without any external agency or overarching purpose. “Nature has no boss” — and therefore no role for a Creator. It’s just the physical world, doing what it does: falling forward forever.

Connectivity is a double-edged sword. For normal operating systems like the Internet, airline networks or the stock exchange, we want them to be heavily connected. But when we think about epidemics spreading, we want to curtail the extent of the connectivity.

Even when high connectivity is desirable, it can sometimes backfire, causing a potentially catastrophic collapse of the system. We want to be able to intervene in the system easily to enhance or delay its connectivity, depending on the situation.

the advantage of starting over: world war II edition

It starts at the end of World War I, when the defeated German army was stripped clean. Part of the Armistice that ended the war forced the dismantling of Germany’s military. This included virtually every weapon it owned. In the years after World War I the Allies undertook one of the largest industrial demolition campaigns in history. Six million rifles, 38 million projectiles, half a billion rounds of ammunition, 17 million grenades, 16,000 airplanes, 450 ships, and millions of tons of other war equipment was destroyed or stripped from Germany’s possession.

Germany’s upside was that every piece of equipment it had in 1939 was based off the latest technology. Not a single possession – from uniforms to guns to submarines – was outdated or obsolete.That wasn’t the case for the Allies at the start of the war. When the war began in 1939, U.S. Army troops carried 1903 Springfield rifles. France had sluggish World War I-era tanks. Britain, at one point, pulled 19th century cannons out of museums to prepare for a German invasion.

There’s a set of advantages that come from being endowed with resources. There’s another set of advantages that come from starting from scratch. The latter can be sneakingly powerful.

Sameness-as-a-service: when every airbnb feels the same

The Airbnb experience is supposed to be about real people and authenticity. But so many of them are similar, whether in Brooklyn, Osaka, Rio de Janeiro, Seoul, or Santiago.

The connective emotional grid of social media platforms is what drives the impression of AirSpace. If taste is globalized, then the logical endpoint is a world in which aesthetic diversity decreases. It resembles a kind of gentrification: one that happens concurrently across global urban centers. Just as a gentrifying neighborhood starts to look less diverse as buildings are renovated and storefronts replaced, so economically similar urban areas around the world might increasingly resemble each other and become interchangeable.

packet switching: an under-rated invention

With traditional telephone connections, the bandwidth needed for the call is dedicated to the call for its full duration (called circuit switching). Even in complete silence, when neither person is talking, the full bandwidth is reserved and cannot be used for anything else. This is analogous to reserving a whole lane of the freeway from San Francisco to Los Angeles, for the full duration of your car ride.

Broadband internet required numerous inventions, but one of the most important was packet switching. Instead of sending the data through one channel, one bit at a time, in the right order, packet switching networks break up the data stream into little “packets.” These packets are individually labeled and tracked by routers and switches, which send them along multiple pathways through the network and then reassemble them at the other end. This is analogous to a car using up only the space it actually needs at any given time, and leaving the lane behind it and in front of it for other cars to use.

JEFF BEZOS: TYPE 1 VS. TYPE 2 DECISIONS

Some decisions are consequential and irreversible — one way doors — and these decisions must be made methodically, carefully, slowly, with great deliberation and consultation. If you want through and don’t like what you see on the other side, you can’t get back to where you were before. We can call these Type 1 decisions. But most decisions aren’t like that — they are interchangeable, reversible — two-way doors. If you made a suboptimal Type 2 decision, you don’t have to live with the consequences for that long. You can reopen the door and go back through. Type 2 decisions can and should be made quickly by high judgment individuals or small groups. 

As organizations get larger, there seems to be a tendency to use the heavy-weight Type 1 decision-making process on most decisions, including many Type 2 decisions. The end result of this is slowness, unthoughtful risk aversion, failure to experiment sufficiently, and consequently diminished invention. We’ll have to figure out how to find that tendency. 

And one-size-fits-all thinking will turn out to be only one of the pitfalls. We’ll work hard to avoid it… and any other large organizations maladies we can identify.

We had assumed an onerous yoke, that of mortal responsibility. Our patients' lives and identities may be in our hands, yet death always wins. Even if you are perfect, the world isn't. The secret is to know that the deck is stacked, that you will lose, that your hands or judgment will slip, and yet still struggle to win for your patients. You can't ever reach perfection, but you can believe in an asymptote toward which you are ceaselessly striving.”

A network does for 21st-century brand communication what the TV did for the 20th and print did for the 19th: It conveys brand identity in a tangible form.

Tyler Cowen on education and the internet

Our education system is failing us. 

This thing called the internet has come along and for actual learning, it’s outcompeted what we call education. It’s not even close. And so much of the internet is free or fairly cheap. And it works on principles that are so much better than what you’re given in so many classes. 

I think the time is right for some real revolution where what we call education in some ways becomes more like the internet. 

We’re going about it wrong. What we’re doing now is we’re taking education as we knew it and we’re adding on the internet. So you’re assigned a YouTube video in your class and students email you. Fine. No reason not to be excited about that. 

But the real gain is to make the internet the center and add on education at the fringes. We are very far from doing that.

How cameras distort images

That old cliche about how the camera adds ten pounds? It refers to the distorting effect of wide angle lenses which are very common in television and film, especially for a lot of closeups and medium shots. If you ever see an actor or model in person they look surprisingly thin. People who look normal on camera look thin in person, and models, who look thin on camera, look malnourished in person.

There's a reason a portrait lens is usually longer than neutral, often starting at 85mm or longer, and why fashion shoots often use telephoto lenses that require a photographer to stand really far from their subjects, sometimes so far they have to shout directions to the model through a megaphone. The longer the lens, the shallower the focus, the more flattering the portrait.

The story of technology is in fact the story of textiles. From the most ancient times to the present, so too is the story of economic development and global trade.

As much as spices or gold, the quest for fabrics and dyestuffs drew sailors across strange seas. In ways both subtle and obvious, textiles made our world.”

I’m good at what I do, but walking in each night, I remind myself we (NYU) are charging kids $500/minute for me and a projector. This. Is. Fucking. Ridiculous.”

ed thorpe: Edges are limited

"Every stock market system with an edge is necessarily limited."

Every edge has a scale limit. Certain securities have a limit.

If you short an over priced stock, it's price will go down so it will be less over priced. And if you buy an underpriced stock, it's price will go up, and it will be less underpriced. Both drive to the correct price.

kobe bryant's wonderful message to gordon hayward

Background: Gordon Hayward, a basketball player for the Boston Celtics suffered a horrific injury last night. Don't watch it. It's gross. 

"Be sad. Be mad. Be frustrated. Scream. Cry. Sulk.

When you wake up you will think it was just a nightmare only to realize it’s all too real. You will be angry and wish for the day back, the game back THAT play back. But reality gives nothing back and nor should you. Time to move on and focus on doing everything in your power to prepare for surgery, ask all the questions to be sure you understand fully the procedure so that you may visualize it in your subconscious while being operated on and better the chance of it’s success. Then focus on the recovery process day by day by day. It’s a long journey but if you focus on the mini milestones along the way you will find beauty in the struggle of doing simple things that prior to this injury were taken for granted. This will also mean that when you return you will have a new perspective. You will be so appreciative of being able to stand, walk, run that you will train harder than you ever have. You see the belief within you grow with each mini milestone and you will come back a better player for it.

Best of luck to you on this journey my brother."

Streams: A return to ancient times

Today, we get most of our news through streams: Twitter, Facebook, LinkedIn, etc. 

As Nassim Taleb pointed out, streams might be a return to ancient form of how news travelled. 

"In the Ancient Mediterranean marketplaces, people talked; they were the receivers and the purveyors of news. Barbers offered comprehensive services; they doubled as surgeon, dispute resolution experts, and news reporters. If people were left to filter their own rumors; they were also part of the transmission. Same with pubs and London coffee houses. In the Eastern Mediterranean (currently Greece and the Levant), condolences were the source of gathering and transmission –and represented the bulk of social life."

kayfabe: the coolest word you've never heard of

“Although the etymology of the word is a matter of debate, for at least 50 years ‘kayfabe’ has referred to the unspoken contract between wrestlers and spectators: We’ll present you something clearly fake under the insistence that it’s real, and you will experience genuine emotion. Neither party acknowledges the bargain, or else the magic is ruined.

To a wrestling audience, the fake and the real coexist peacefully. If you ask a fan whether a match or backstage brawl was scripted, the question will seem irrelevant. You may as well ask a roller-coaster enthusiast whether he knows he’s not really on a runaway mine car. The artifice is not only understood but appreciated: the performer cares enough about the viewer’s emotions to want to influence them. Kayfabe isn’t about factual verifiability; it’s about emotional fidelity.”

people care about people, not brands

Virgil Abloh (Founder of Off-White): “Now we’re at a point where influencers are just as big as media outlets. If you have that many followers, and you’re selling a 30-dollar hoodie, you can sell way more without magazines ever writing about it. Something I’ve noticed about streetwear designers is that they always refer to their customers as “kids.” 

Virgil Abloh: My idea is to build a vocabulary and a lineage. Because brands are only as old as the people who direct them. That’s why you’re now seeing a deterioration of people following brands, as opposed to designers and stylists. 

Interviewer: So it’s going to be about celebrity?

Virgil Abloh: It’s going to be about visionaries.”

Learning from traffic flow

"At rush hour on the Los Angeles freeway system, stoplights operate at the freeway on-ramps. We hold arriving cars in this queue and release them at a regular cadence onto the highway. This conditions the flow arriving on the freeway and prevents us from injecting cars onto the freeway at highly variable rates.

This, in turn, is important because highly variable arrivals generate what are called “shock waves” when freeways are congested. If a group of cars merges onto the freeway, this causes nearby cars to slow. The following cars react later and have to decelerate even more quickly. This, in turn, leads to an accordion-like pattern of turbulence in traffic flow. This turbulence can be reduced if the injection rate is conditioned by a metered queue at the on-ramp.

The exit rate of this queue becomes the low-variability cadence of the stoplight, instead of the high-variability pattern of driver arrivals at the on-ramp. Of course, when there is no queue at the on-ramp, the injection rate onto the freeway will be identical to the arrival pattern at the on-ramp."

Millennials are the first generation to acquire trust digitally.

"Baby boomers, I think by and large acquire trust through the handshake. Look someone in the eye, shake their hands. You know financial advisors, you go into their office and you shake their hand. It is a face to face interaction and that’s how trust was acquired.

Millennials I think were the first generation to acquire trust digitally. So it’s not that millennials had more information online than baby boomers, but millennials were much more likely to use the information that they have online to build a sense of trust."
