What is the most underrated innovation of the last one hundred years?

That was another question I was asked.

I find it difficult to compare the “ratings” of early 20th century innovations to the ratings of innovations today, since it is often different audiences doing the admiring, or lack thereof.

For the most underrated innovations of the last one hundred years I might pick the insights of Alan Turing, various developments in electrical engineering including better transformers, or the nitrogen-fertilizer connection, noting that in some quarters there is already plenty of recognition for each of these, Turing in particular.  But still not enough!

As for contemporary innovations, I see an underrated one as Amazon’s warehousing and shipping practices.  It will mean the death of much of retail and transform our suburban physical spaces into something quite…????.   Into something, in any case.  I am a social networking optimist, and think it has largely beneficial effects on social mores, but I also see it as having peaked at a near-saturation point.

Here is a good video on “Amazon yesterday shipping.”

dearieme August 13, 2012 at 7:51 am

What often gets underrated is the development of skill at using different policies or technologies integrated together.

An example from WWI was the integration of infantry, artillery, tanks, reconnaissance aircraft and a mechanised supply chain, which in 1918 proved a winning formula. Much better known is the WWII integration of fighter aircraft and radar which proved key in 1940 for Britain, and the integration of armoured divisions and dive bombers which did so well for Germany.

Can anyone suggest overlooked integrations?

Maximum Liberty August 13, 2012 at 1:53 pm

Wal-Mart’s supply chain management.

Max

Orange14 August 13, 2012 at 3:03 pm

Correct; they set the standards which Amazon and everyone else have copied.

liberalarts August 13, 2012 at 7:58 am

I never hear anyone talking about the development of plastics, without which we would be a very different and very much worse world. (Outside of the tip Dustin Hoffman got in The Graduate.)

Benny Lava August 13, 2012 at 8:00 am

How about flushing toilets? Or the alarm clock?

Roy August 13, 2012 at 9:25 am

Both are nineteenth century inventions. But I agree they are awesome

Benny Lava August 13, 2012 at 7:19 pm

Drat! What about the semiconductor?

AC August 13, 2012 at 8:01 am

Social networking benefits social mores? Maybe in the sense that it fosters weak ties. It is now possible to vaguely keep track of lots of acquaintances you don’t strongly care about, who in the past you would have forgotten.

I’m not sure that this offsets the amount of costly status-seeking performance that goes on (the race to have lots of pictures of yourself acting high-status at parties, the false fawning over female friends’ profile pictures). Nor, among the more future-time oriented young people, the conformity effect where unusual or controversial thoughts and lifestyles become more costly and difficult to hide.

I see social networking as basically a pro-conformity force, “conservative” in a catholic sense that includes punishing political incorrectness, that mildly strengthens weak ties at the cost of opening a new front in zero-sum status competition.

Zachary August 13, 2012 at 9:30 am

If your FB punishes political incorrectness, then you have a unique set of friends. I’ve never seen so much direct direct commentary of social problems or expression of biases. I don’t at all understand the last clauses of your last sentence. So we get stronger ‘weak ties’ and in exchange we give up ‘zero-sum’ status competition?? This all sounds ‘good’.

AC August 13, 2012 at 9:58 am

Certainly in social circles where political incorrectness is expected, facebook encourages political incorrectness. However that kind of culture is rare in the more influential circles, where I am a third-tier spectator. (This is ignoring humorous faux-political-incorrectness, like those making fun of Irish or Chinese. If it wouldn’t get sink your academic career to leak it on Gawker, it’s not real political correctness.)

And you misread me: I think we get stronger weak ties but MORE status competition.

GW August 13, 2012 at 8:02 am

If you are to identify Turing’s insights as underrated, then surely those of Alonzo Church are even more underrated, as Turing has become a public persona and Church remains unknown except to specialists, the disadvantage, one supposes, of a less colorful biography.

I agree that Amazon’s warehouse and shipping practices are underrated, but I will be even more curious to learn how their pricing practices perform over time (and naturally wonder about the great “what if” of how the Soviet Union’s economy would have performed had it had access to a similar system!)

Dave August 13, 2012 at 9:20 am

I’m a bit shocked that Tyler would consider Turing relatively unknown particularly given that The Turing Award, the so-called Nobel Prize for computing, is named after the guy and pretty much any computer scientist will bump into Turing machines. (His name is still even popping up in the news, albeit primarily due to the history of how he was treated as a homosexual).

I suppose that the original post did mention that: “in some quarters there is already plenty of recognition for each of these, Turing in particular. But still not enough!” How much would be enough though? If you asked the average person on the street to name even five 20th century scientists or five 20th-century economists (etc), what fraction of the population do you think would actually succeed at the task?

RNT August 13, 2012 at 11:08 am

If you we are talking about underrated scientists, I would pick Claude Shannon. He is iconic in the world of communication systems but little known except to EE/CS theorists. Information theory is stunningly elegant and has had a profound impact on everything from space exploration to CDs to wireless communication to the internet.

Jon Gertner in his recent book The Idea Factory says something like “The transistor revolutionized computing, but it was an invention waiting to happen. But Shannon’s theory was nowhere on the horizon. I might have been 20, 30, even 50 years before these ideas of representing information crystallized.”

Oh, and Shannon had a seminal master’s thesis as well- using Boolean algebra to design digital circuits.

amal ekbal August 13, 2012 at 11:31 am

+1 for Claude Shannon. It is amazing how much of the communication revolution was spurred by the fundamental ideas contained in his work.

da55id August 13, 2012 at 5:58 pm

+0/1 for Claude Shannon.

nickMR August 14, 2012 at 1:56 am

I’d add Andrey Kolmogorov, who generalized Shannon’s theories and unified them with computer science. (Chaitin and Solomonoff also get kudos here).

John Thacker August 14, 2012 at 6:02 pm

Computer science? Kolmogorov’s work in axiomatizing probability theory are worth it alone. Kolmogorov was one of the greats.

I’m honored to have taken graduate probability from his student, the also eminent Eugene Dynkin.

Nancy Lebovitz August 13, 2012 at 8:05 am

One side effect on online shipping becoming easier and cheaper is that there’s less variety in stores. If you want something today rather than in a day or two or you aren’t in a good position to receive packages, this can be a problem.

Alan August 13, 2012 at 8:19 am

One economist down under cited the shipping container, mainly on the grounds that it reduced employment opportunities for stevedores, whom he hated.

Rahul August 13, 2012 at 10:31 am

On a similar note, the American Interstate system?

bunker brown August 14, 2012 at 12:27 am

Citation for ‘economist down under’ please?

Ted Craig August 13, 2012 at 8:29 am

Radio is underrated today. I’ve heard the claim it saved the homogeneity of American English.

dearieme August 13, 2012 at 9:02 am

saved or imposed?

GiT August 13, 2012 at 8:30 am

Ted Craig August 13, 2012 at 8:51 am

Is it underrated if they made movie about it?

http://www.imdb.com/title/tt0063467/

Sergey Kurdakov August 13, 2012 at 8:34 am

I think that underrated is continuous improvement in energy efficiency.

In case we used the same amount of fuel to get same output as at the beginning of XX century we would spend not 5% on fuels, but almost all our money just on purchasing fuel. ( See works by Ayres ).

Angus August 13, 2012 at 8:53 am

RZ0 August 13, 2012 at 9:23 am

Computers. I read a book by a famous economist that said the internet was the only major innovation since television. (I read this book on my telephone, btw.) That tells me that computers are pretty underrated.
:)

dearieme August 13, 2012 at 9:51 am

Apart from penicillin?

Roy August 13, 2012 at 9:23 am

Several that have provided the power of the 20th century

Most of all: Seismic testing and almost the entire field of geophysics, also sonar and radar that modern life would not be possible without. Heck even the cheap and easy construction of large structures and multistory buildings in all environments would not be possible without basic seismic testing to find bedrock depths and social compaction rates

In addition there are a lot of technical innovations in well manigement that are totally unappreciated outside of the field that have allowed the huge supplies of both oil and groundwater needed for modern life

-the invention of well logging through electrical resistivity by Schlumberger

-the portable truck mounted drilling rig and the invention of directional drilling

And a couple that gave us the huge step up in agricultural productivity in second half of twentieth century
-The Theis Equation that allowed the first true method of studying aquifer storarivity and conductivity
-Center pivot irrigation

chuck martel August 13, 2012 at 10:03 am

the cheap and easy construction of large structures and multistory buildings in all environments

We’re probably not going to see many more skyscrapers being built, at least as corporate-ego trip home offices. The trend will be to disperse employees that seldom communicate face-to-face even now to cheaper locations closer to their homes where they will make use of electronic means to carry on business.

Roy August 13, 2012 at 11:53 am

My mother has a three story house we did a seismic test for, even building a shopping center competently generally requires one. And for highways and runways it is completely necessary. Also if you build a tunnel without one you are basically playing craps, though in most environments your odds would be much better in a casino. Building a dam or retention pond without one can actually ger one improsoned for negligent homicide in the US or Europe, and executed in some Asian countries. And that is aside from the huge change of just midrise structures to the worlds urban/suburban landscape.

The ubiquity of the use of a strike plate, a string of seismophones and a sledge hammer to determine bedrock depth is so established and cheap that you might as well argue the theodolite is an obsolete invention.

celestus August 13, 2012 at 9:28 am

Does genetic engineering count for the last one hundred years? Pretty hard to think of something that has saved as many lives and yet is not only underrated, but isn’t even considered a plus by much (most?) of the world.

Factory farming certainly should count for the last one hundred years, and has much of the same logic behind it. More food, more surplus American labor to invent the Internet and things like that, despised by the public.

Ryan Cousineau August 13, 2012 at 4:04 pm

Selective breeding has been around for much longer than a hundred years, and genetic engineering in the direct, GM-sense of the phrase has led to important but (in my opinion) relatively incremental improvements so far.

Norman Borlaug and the Green Revolution get a lot of publicity in the right circles (including here on MR) and he did win a Nobel Peace Prize and various other major gongs, but given that there are not yet statues of Borlaug 100 feet tall in every major agricultural region, he may still be underrated :).

Why do I say that? Wheat yields in 1950 should have been one of those things that was the very definition of a mature technology: we’ve been working on it for millennia, it’s the focus of much study, and a 10% increase would have been big news. Instead, the Green Revolution saw crop production double in 35 years.

I also like the nominations for containerization. That enormously increased the efficiency of shipping, and I don’t think people think about the “pre-container era” with nearly the awe they hold for, e.g., the “pre-car” or “pre-telephone” or “pre-computer” eras.

If I had to pick an innovation that is seen as novel today, but not yet crushingly important, I would pick “telecommuting,” by which I mean all the ways work is organized by groups that are not in the same geographical location (this ambitious definition could include everything from outsourced production to online learning). I don’t think this has nearly reached its potential, and the current tools are underused or underdeveloped or misunderstood, but in my opinion we’re not far from a sudden moment where the tools for group-y action at a distance* will become good enough, and white-collar offices will empty out surprisingly quickly.

And self-driving cars are the innovation that is not yet in production, but will be astoundingly ubiquitous (and surprisingly transformative) very soon after it is available for sale.

*I could not help myself.

Bender Bending Rodriguez August 13, 2012 at 5:46 pm

Another vote for the shipping container. I moved from the US to the South Pacific, and it was dead cheap to have our household goods moved. The container shows up at the house, and professionals packed it up right in front of us. On the other end, I could see that nothing had been tampered with. And cost-wise, the modularity made it cheap enough that the container could be moved “hub and spoke” instead of “point-to-point”. The container went by road to LA, and then by ship to China, Australia, and then New Caledonia. Pre-container, it would have been a shit-load of crates, any one of which could have gone missing, and the cost for a point-to-point shipment from LA to Noumea would have been staggering.

Roy August 13, 2012 at 9:28 am

Radar, in addition to military and safety uses think of the impact of meteorology

Sonar, which allowed the rapid mapping of the ocean floor

Laura M. August 13, 2012 at 9:31 am

My vote is for linear programming. Being able to solve large-scale optimization models has led to so many improvements in logistics and operations.

Doc Merlin August 13, 2012 at 3:15 pm

Zachary August 13, 2012 at 9:36 am

The practice and logistics behind nightly grocery store shelf stocking. The store saves a boat-load of money on storage costs and the customer never has to wait more than one day for an item to be available for purchase (If ever at all). Each day, the store gets depleted and then replenished by the next morning. Simple, boring, and too convenient.

The Original D August 13, 2012 at 11:39 am

This is a good one. My local Whole Foods has an amazing food court with creative hot meals that change every day. I would love to do a tour of the warehouse where this is all made.

Ryan Cousineau August 13, 2012 at 4:24 pm

The technology known as “table d’hote” predates the 20th century.

Just-in-time inventories are a notable technology, but grocery store restocking is a small subset of a much more general trend. And I don’t think the inventory turns are quite as dramatic as you believe, though. Industry superstar Costco has a turnover ratio of 12 or so, which equates to selling out the entire store once a month (Walmart is about 8 (and you can assume every other retailer in the groceries/soft-goods world would kill to see those turnover ratios.))

The most noteworthy inventory freaks are two companies at opposite ends of the retail spectrum: Apple (74) and McDonald’s (142), the latter getting very close to your dream of a store that is depleted every day (it is actually a bit more than every two days).

I was going to suggest chlorinated water supplies, but that really started late 19th/early 20th… so perhaps the use of liquefied chlorine gas to disinfect water supplies?

Grahame August 13, 2012 at 9:43 am

No one has mentioned anti-biotics and/or immunization. I can only presume this is because they usually get a rating, but it’s still hard to rate these two highly enough

Andreas Moser August 13, 2012 at 9:45 am

Logically, the most underrated invention will be something that none of us will think of.
This question is a paradoxon.

John Thacker August 13, 2012 at 10:04 am

Not necessarily. The most underrated invention could still be something highly rated, just not rated highly enough. “Most underrated” is not well-defined. Particularly as the number of responses increases, it’s likely that someone will think of it.

However, it’s unlikely that we’ll agree on the correct answer. Unless the particular type of most underrated is something that falls into the “taken for granted, but when you think about it, obviously very important and worthy of greater recognition” category.

Vangel August 13, 2012 at 9:48 am

I would argue that it is air conditioning. It allowed areas that were not very productive due to excessive humidity and high temperatures to create comfortable working and living environments.

As a southerner, and a native Houstonian no less, I can assure you that a/c is probably the most highly regarded invention in my hometown. Also Willis Carrier, may peace be upon him, invented the modern air conditioner in 1902, which was 110 years ago.

The credit card.

Revolving credit existed at least back to the 1600s, at least for a very few, but what amounts to a bearer instrument for loans radically changed retail in ways that are still being sorted.

lemming August 15, 2012 at 5:07 pm

If credit cards are som important, why are there so big differences in usage? In Sweden everyone carries a debit card, but credit cards are not at all as common as in the U.S.

Mark Thorson August 13, 2012 at 10:08 am

The biggest invention you’ve never heard of is the Lake relay (also known as the storage counter). Before the Lake relay, punched cards were not very useful. The Lake relay was the key invention that made possible the electronic accounting machine, which revolutionized data processing, made a fortune for IBM, and paved the way for IBM’s dominance of computers for 30 years. Young people today look at a bill or invoice printed by a machine in the 1930s, and they don’t have a clue how it could have been made. It was printed by an EAM.

One Lake relay provides storage and computation for one decimal digit. It can be read electronically and it can perform addition and carry. A bank of relays is a register which can be used to tally a total from a deck of punched cards representing individual unit sales, as well as many other operations. An EAM is programmed by interchangeable plugboards, so a shop with one EAM can service many clients by simply swapping plugboards.

The Lake relay was invented by Clair D. Lake, truly one of the least known giants of 20th century technology.

dearieme August 13, 2012 at 10:10 am

How about income tax directly debited from your pay? That must have changed enormously the finances of states and therefore their ability to fund wars, welfare states and so forth. By partially disguising taxation rates, it probably amplified the state’s ability to take wealth and power from its citizens.

kiwi dave August 13, 2012 at 12:25 pm

Ironically, the US has Milton Friedman to thank for that.

If every worker had to write a large cheque (or “check”) to the IRS (or that country’s equivalent) annually (or quarterly), the state would be a lot smaller.

Lee Kuan Yew liked the air-conditioner.

Foobarista August 13, 2012 at 7:13 pm

Related to air-conditioning is refrigeration. The modern world couldn’t exist without it. (And Singapore wouldn’t exist as a place where anyone would want to do business without both.) While refrigeration was reasonably well-understood and used in shipping and manufacturing environments by 1900, large-scale use of non-ice-box refrigeration wasn’t done until the mid 1930s.

And when you combine cheap refrigeration with standardized shipping containers, you can ship food anywhere on earth…

Richard August 13, 2012 at 10:31 am

I actually got asked a similar version of this question on my Microsoft interview: “What is the most important non-STEM innovation in the past 50 years?” It’s actually quite hard if you think about it given how much of our progress has been due to STEM advances. This was also eye-opening in making me realize how little I knew about advances in the arts.

Mark Thorson August 13, 2012 at 11:09 am

That is a tough question. It excludes virtually everything related to materials, processes, genetics, communications, etc. That leaves what? Military tactics, politics, business methods, advertising, architecture, artistic expression, food preparation — but the 50-year time limit excludes much from these fields. I know somebody had a patent on the Please Wait Here For Next Available Teller sign for creating one line that served multiple checkers/tellers, which was one of the earliest business method patents. I think that was after 1962, so it might qualify.

The Original D August 13, 2012 at 11:42 am

You should have said “Apple’s advertising.” :)

Mark Thorson August 13, 2012 at 1:19 pm

Now that I’ve thought about it some more, “reality” TV shows and securitization of mortgage debt seem like better answers.

The way this question is phrased, I probably would’ve replied desegregation, though that might be outside the intended realm of the question.

Joe Lehman August 13, 2012 at 10:59 am

I nominate the deregulation of trucking that began in the late Carter administration. While it might be described as a “corrective” more than an “innovation,” it made possible just-in-time inventory practices and the rise of Wal*Mart style retailing. Deregulation removed massive amounts of friction from the system and made many other innovations possible.

Yancey Ward August 13, 2012 at 2:50 pm

Also an excellent suggestion.

YSK August 13, 2012 at 11:01 am

The most underrated innovations are management practices (including those stated above such as integration, linear programming, Amazon’s warehousing). They do not get enough attention since they are too diffuse and seem obvious once they spread. Also, most people implicitly assume that innovations occur only in STEM fields. Of the many underrated innovations in business, the most underrated is the multi-business firm.

B.B. August 13, 2012 at 11:25 am

I vote for the air conditioner.

The economic and social development of the Sun Belt would not have happened without it. Ultimately, it could spur economic development in tropical countries.

I am sure it has boosted productivity of all insider workers and students during the warm months.

It may have had an important and underappreciated role in the reduction in violent crime seen in recent decades as a/c spread to households. Overheated people suffer psychological stress and greater irritability, which can trigger violence.

Milton Friedman thought that a/c made living in Washington DC bearable and so encouraged the growth of central government.

M.R. Orlowski August 13, 2012 at 11:50 am

Well, I’m not so sure whether this innovation is “underrated” but the electric bass guitar was invented during the 20th century. Many musical genres wouldn’t be here today if not for that instrument.

R. Roberts August 13, 2012 at 12:25 pm

I would say the Haber-Bosch Process. The process was first realised on an industrial scale in 1913 so just falls within the 100 year window. It produced the nitrates behind the German WWI war effort when Britain had a virtual monopoly on nitrate sources and it currently produces fertiliser that is responsible for the feeding of about 1/3 of the world’s population. Seems fairly important to me and the fact that no-one has mentioned it yet suggests some degree of underratedness.

kiwi dave August 13, 2012 at 12:33 pm

Agreed, I was also very surprised no-one else mentioned that one. It might be well-known among chemists, but I think it is hardly known to the general public, even the more educated part of it. As you mentioned, it had some negative effects (the Central Powers war effort couldn’t have lasted into 1915 without nitrogen fixation given the Royal Navy blockade) but its importance is utterly undeniable.

Agreed. The nitrogen-fertilizer connection was already well recognized by the middle of the 19th century, and took the form of knowledgeable (not just empirical) use of legumes for nitrogen fixation (splitting N2 to N, resulting in nitrates, ammonia, urea, or similar) and the use of ammonia-rich guano and mineral nitrates for fertilizer.

But the Haber-Bosch process greatly improved on these techniques.

The role of nitrogen fixation in the early history of life is also greatly underrated.

BIOS. To me it is simply amazing. Apply power and something happens, and all of IT comes after.

Peter Y. August 13, 2012 at 1:34 pm

Some designs are inevitable—spoons, road signs, shipping containers, etc. While its inevitability doesn’t mitigate the respect that its inventor deserves, it does somewhat mitigate the importance of the invention (not the end product). For example, the invention of the chair is an unremarkable event (perhaps because we don’t know who invented it or how it was invented), but its importance in today’s society is unrivaled. Can you imagine working 8+ hours/day without sitting down?

Thus, I would argue that things like air conditioning, shipping containers, credit cards, etc., are very important to society, but should not be considered noted inventions. It’s only the invention of something that is incredibly innovative and unique that should be categorized as a truly breakthrough invention.

It would only have been a matter of time before someone standardized shipping container sizes, or devised an apparatus to separate room-temperature air into cold air and hot air, or put graphics on computers, or figured out how to mail packages cheaply and quickly.

Most of the important things we have “invented” are just products of intellectual evolution. Does that mean that inventors shouldn’t get any credit? Of course not—they were the first to think of it. However, the standardization of shipping containers doesn’t get the credit as the enabling invention of large-scale international trade, and that’s the way it should be.

If you think about it, suddenly all inventions seem to be unimportant. After all, it would only be a matter of time, right?

Dangerous way of thinking, for sure.

nickMR August 14, 2012 at 2:06 am

Can you imagine working 8+ hours/day without sitting down?

That used to be the norm. And we’d be much healthier.

Matt2 August 14, 2012 at 7:56 am

I disagree with you on the container issue. A single container ship worked with five cranes can easily discharge over 20,000 tons of goods in an eight hour shift. The volume and value of goods that we move in Malcom’s boxes would be impossible were we still using the crate and pallet methods that were good enough for a couple thousand years. You couldn’t build enough docks, warehouses, ships, and boxcars. In the field, the invention and standardization of intermodal contaienrs gets a huge a deserved amount of credit for the increase in international trade over the past 50-60 years.

The Voting Rights Act and related Civil Rights legislation. In my lifetime I have seen as a child segregated restrooms (I remember on a trip to Tennessee that I wanted to go into the colored restroom since all the ones I had seen had black and white tile). Recently, on a trip through the deep south, I noted the number of multi-racial families. Everywhere in America one sees multiracial ads, news teams, etc. Differences from 60 years ago occur almost on an hourly basis for many of us.
