Scientific Concepts From ‘This Will Make You Smarter’ – Business Insider
Flickr / trugiazThe editors over at Edge.org asked some of the most influential thinkers in the world — including neuroscientists, physicists and mathematicians — what they believe are the most important scientific concepts of the modern era.
The result is “This Will make You Smarter: New Scientific Concepts To Improve Your Thinking,” a compilation of nearly 200 essays exploring concepts such as the “shifting baseline syndrome” and a scientific view of “randomness.”
We’ve highlighted 39 of the concepts here, crediting the author whose essay highlights the theory.
Cognitive humility
Decades of cognitive research shows that “our minds are finite and far from noble. Knowing their limits can help us become better reasoners. … Perhaps the most dire consequence is that human beings tend to be better at remembering evidence consistent with their beliefs.”
Gary Marcus, director, New York University, Center for Child Language. Author, Kluge: The Haphazard Evolution of the Human Mind from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Cognitive load
Our brains can only hold so much information at once. When there’s too much “information overload,” we tend to get distracted easily and not retain what we’re learning.
“Working memory is what brain scientists call the short-term store of information where we hold the contents of our consciousness at any given moment — all the impressions and thoughts that flow into our mind as we go through the day.”
Nicholas Carr, author, The Shallows: What the Internet is Doing To Our Brains, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking.
Constraint satisfaction

When presented with too many choices — no matter how beautiful or beneficial — it can be overwhelming, and we are paralyzed by indecision.
That’s why having constraints, or any sort of limits, is beneficial and leads to solutions.
In fact, “much creativity emerges from constraint satisfaction. … Einstein had one of his major breakthroughs when he realized that time need not pass at a constant rate.”

Contingent superorganisms
“Biologists have joined with social scientists to form an altruism debunkery society” — pushing the belief that every altruistic act is done in self-interest.
But a new concept, “contingent superorganisms,” says that we live life on a few different hierarchies. The idea is that when you reach a higher level, you are willing to put the success of the group or a higher cause above one’s own. This is what drives militaries, fire departments, and rock bands.
Jonathan Haidt, social psychologist, University of Virginia from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Copernican principle
The Copernican Principal is the idea that we are not special — that the universe is much larger, and we have a rather insignificant role.
“The paradox of the Copernican Principle is that by properly understanding our place, even if it be humbling, we can only then truly understand our particular circumstances. And when we do, we don’t seem so insignificant after all.”
Samuel Arbesman, research fellow, Harvard Medical School Department of Health Care Policy from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Cultural attractor
We are attracted to ideas and concepts that are easy to accept or digest.
For example, round numbers are cultural attractors — they’re “easier to remember and provide better symbols for magnitudes.” Efficiency is another powerful cultural attractor.
But just because we are drawn to specific concepts, does not mean that they are the best ones to apply to any given situation.
Dan Sperber, professor of cognitive science, Central European University, Budapest from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking.
Cumulative error
When information travels through multiple channels, it’s easy for some elements of the message to get distorted — by biases, or simple human error.
The effect of the spread of misinformation is “cumulative error.” Living in an age where information can travel across the world in nanoseconds, this concept has never been more real or dangerous.

Cycles

Cycles explain everything — especially, at the basic level: evolution and biology. Cycles can be disrupted. Also watch out to see which cycles are doing all the work.
“All the ‘magic’ of cognition depends, just as life itself does, on cycles within cycles of re-current, reflexive information-transformation processes, from the biochemical scale within the neuron to the whole brain sleep cycle, waves of cerebral activity and recovery revealed by EEGs.”
Daniel Dennett, director, Center for Cognitive Studies, Tufts University, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Deep time
The belief that there is much more time before us than has already elapsed. This creates a more expansive view of the world and the potential of the universe.
“Our sun is less than halfway through its life. It formed 4.5 billion years ago, but it’s got 6 billion more years before the fuel runs out.”
Martin Rees, professor of cosmology & astrophysics, Trinity College and the University of Cambridge. Author of Our Final Century: The 50/50 Threat to Humanity’s Survival, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Double-blind control experiment
It’s a tool that researchers use to prevent against subconscious bias when performing experiments.
Understanding the need for double-blind experiments would help the rest of the population understand their inherent subjective, everyday biases, and guard against generalization and impress upon people the need for critical thinking.
Richard Dawkins, evolutionary zoologist, University of Oxford, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking.
Effective theory
“‘Effective theory is one of the more important notions within science — and outside it. The idea is to determine what you can actually measure and decide, given the precision and accuracy of your measuring tools, and to find a theory appropriate to those measurable quantities.”
Lisa Randall, physicist, Harvard University, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Expanding in-group
AP
As technology makes us more interconnected, there are more cross-overs between groups and populations. For example, there are more intermarriages.
“These effects are potentially beneficial for the improvement of cognitive skills, from two perspectives. We call these the ‘expanding in-group’ and the ‘hybrid vigor’ effects.”
Marcel Kinsbourne, neurologist and cognitive neuroscientist, The New School, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Externalities

We all affect each other incidentally, especially in an interconnected world. Externalities are the unintended positive and negative side effects these interactions have.
“Externalities are increasingly important in the present era, when actions in one place potentially affect others half a world away.”
Rob Kurzban, director, Pennsylvania Laboratory for Experimental Evolutionary Psychology, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Failure liberates success
“Failure is not something to be avoided but something to be cultivated. … It is a sign of weakness and often a stigma that prohibits second chances. … Yet the rise in the West is in many respects due to the rise in tolerating failure. Indeed, many immigrants trained in a failure-intolerant culture may blossom out of stagnancy once moved into a failure-tolerant culture. Failure liberates success.”
Kevin Kelly, editor-at-large, Wired magazine; author, What Technology Wants, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking.
Fear of the unknown
Goldman Sachs Asset Management
Our attachment to the familiar keeps us from taking risks and making real strides and breakthroughs. We often don’t accurately assess the risk/benefit ratio; our irrational fears get in the way of real progress.
“If the public could be brought to a greater understanding of how to evaluate the risks inherent in exploring future technology, and the merits of accepting some short-term risk in the interests of overwhelming greater expected long-term benefit, progress in all areas of technology — especially biomedical technology — would be greatly appreciated.”
Aubrey De Grey, gerontologist, chief science officer, SENS Foundation, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Fixed-action patterns
Some behaviors we exhibit we blame on instinct. But what we believe to be instinct may, in fact, be learned behavior over time — or a “fixed-action pattern.”
This has many implications, including the fact that, as rational creatures, we can change what we believe to be instinctive.
“Given an understanding of our fixed-action pattern, and those of the individuals with whom we interact we — as humans with cognitive processing powers — could begin to rethink our behavior patterns.”
Irene Pepperberg, research associate, Harvard University, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Focusing illusion
Mark Lennihan / AP
We often believe that a certain, different set of circumstances would dramatically change our lives. But the truth is, factors like income and health are less indicative of overall happiness.
“The mismatch in the allocation of attention between thinking about a life condition and actually living it is the cause of the focusing illusion.”
Daniel Kahneman, professor emeritus of psychology and public affairs, Princeton University. 2002 Nobel Memorial Prize in Economic Sciences, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking.
Hidden layers
These are the layers of understanding that exist between the external reality and our own perception of the world.
These systems of layers become more interconnected as we develop habits. Learning to ride a bike was hard; but after a while it’s like second nature.
“The general concept of hidden layers captures deep aspects of the way minds — whether human, animal, or alien; past, present, or future — do their work.”
Frank Wilczek, recipient, 2004 Nobel Prize in physics, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Holism
“Holism is colloquially described as ‘The whole is greater than the sum of its parts.’ … Perhaps the most impressive is that carbon, hydrogen, oxygen, nitrogen, sulfur, phosphorus, iron, and a few other elements, mixed in just the right way, yield life. … There is a kind of awesome synergy between the parts.”
Just look at DNA, and other much broader systems, like cities, that operate only if each individual element does its part.
“Holism does not come naturally. It is an appreciation not of the simple but of the complex.”
Nicholas Christakis, physician and social scientist, Harvard University, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Inference to the best explanation
When any single event occurs, there are many possibilities as to the cause of the event. But the truth often lies in what is the single most reasonable, best explanation for the event.
“Many of our most rancorous scientific debates — say over string theory or the foundations of quantum mechanics — have been … which competing criteria for judging explanations [of] best ought to prevail.”
Rebecca Newberger Goldstein, author, 36 Arguments for the Existence of God: A Work Of Fiction, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Kaleidoscopic discovery engine
Apple
The greatest insights and inventions are the product of multiple people. It’s never just a single person; everyone’s standing on someone’s shoulders.
“In hindsight we often find that if one scientist did not make a particular discovery, some other individual would have done so within a few months or years of the discovery. … We are reluctant to believe that great discoveries are part of a discovery kaleidoscope and are mirrored in numerous individuals at once.”
Clifford Pickover, associate editor, Computers and Graphics; author, The Math Book: From Pythagoras to the 57th Dimension, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Mediocrity principle
Daniel Goodman / Business Insider
The concept that each person is not unique. Instead, mediocrity pervades.
“The universe does not revolve around you; this planet isn’t privileged in any unique way; your country is not the perfect product of divine destiny; your existence isn’t the product of directed, intentional fate.”
P.Z. Myers, biologist, University of Minnesota; blogger, Pharyngula, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Name game
We give names to everything in order to understand the world. But in doing this, we sometimes undermine, or simplify, the true nature of an organism or process. “Naming” keeps us from asking further, deeper questions about the nature of something.
It’s also important not to over-associate words, which leads to misunderstanding — for example, “theory [is] a strong idea in science while vague in common discourse.”
Stuart Firestein, neuroscientist, chair of the Department of Biological Sciences, Columbia University, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Our sensory desktop
We all perceive the world differently, and “our sensory experiences — such as vision, sound, taste, and touch — can be thought of as sensory desktops that have evolved to guide adaptive behavior, not report objective truths.”
Donald Hoffman, cognitive scientist, University of California, Irvine, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Pessimism meta-induction
“Because so many scientific theories from bygone eras have turned out to be wrong, we must assume that most of today’s theories will eventually prove incorrect as well.”
Accepting the belief that many of our theories are “fundamentally provisional and quite possibly wrong,” we can better listen to and empathize with others’ ideas.

Positive-sum games
In zero-sum games, there’s a clear winner and a clear loser. In positive-sum games, “everyone wins.”
“In a positive-sum game, a rational, self-interested actor may benefit the other actor with the same choice that benefits himself or herself.”
Some competition will always be zero-sum — such as the competition for mates.

Powers of 10
Much of the world operates in powers of 10. Understanding scaling laws, like Richter scales that measure earthquakes or of “that between the volume of the brain’s cortical white matter” — where computing takes place — would give us more perspective on the depth of events, matter, and ourselves.
“The spatial scales are also immense. Our space-time trajectory is a very tiny part of the universe, but we can at least attach powers of 10 to it and put it into perspective.”

Predictive coding
(AP Photo/Toby Talbot)
Our expectations — and if they are met or not — greatly influence how we perceive the world, and ultimately, our quality of life.
Predictive coding “concerns the way the brain exploits prediction and anticipation in making sense of incoming signals and using them to guide perception, thought and action.”
Andy Clark, philosophy professor, University of Edinburgh, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Randomness
“Randomness is a fundamental limit to our intuition; it says that there are processes we can’t predict fully. It’s a concept that we have a hard time accepting, even though it’s an essential part of the way the cosmos works.”
But some random events — like random collections of atoms — are so absolute, that we can predict the outcome of that “randomness” with pure certainty.
Charles Seife, journalism professor, New York University; author, Proofiness: The Dark Arts of Mathematical Deception, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Rational unconsciousness
Freud inspired the idea of the irrational subconscious, but many of today’s scientists dispute that idea.
Instead they are bridging the conscious and unconscious — and insisting that we operate on both levels, and have an awareness of this connection, more than we think. “Our conscious understanding of probability, for example, is truly awful, in spite of the fact that we unconsciously make subtle probabilistic judgments all the time.”
Alison Gopnik, psychologist, University of California — Berkeley, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Scale analysis
Citigroup Global Markets
Scale analysis bridges the nonlinear and linear aspects of the world.
“At its core reside two questions. The first asks what quantities matter most to the problem at hand. … The second asks what the expected magnitude and — importantly, dimensions — of such quantities are.”
Giulio Boccaletti, expert associate principal, McKinsey & Co, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Self-serving bias
The idea that we perceive ourselves to be better than we are; to claim responsibility for success and blame others for failure.
“In everyday life, more than nine in ten drivers are above-average drivers, or so they presume. In surveys of college faculty, 90 percent or more have rated themselves as superior to their average colleague.”
David Myers, social psychologist, Hope College; author, A Friendly Letter to Skeptics and Atheists, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Shifting baseline syndrome
The belief that what we perceive is what’s normal, not taking into account the full extend of the past nor potential for future events.
The syndrome is named after scientist Daniel Pauly, who said that each generation accepts “as a baseline the stock size and species composition that occurred at the beginning of their careers, and uses this to evaluate changes. When the next generation starts its career, the stocks have further declined, but it is the stocks at that time that serve as the new baseline.”
Therefore what is “normal” is constantly changing.
Paul Kedrosky, Senior fellow, Kauffman Foundation; editor, Infectious Greed, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Skeptical empiricism
“Skeptical empiricism, the kind exemplified by the carefully thought-out and tested research in science at its best. It differs from plain empiricism” — which is simply the observation of results of the world around us.
Put more simply, it is important for us to be skeptical about the world around us and not blindly accept what we believe to be “truths.”
Gerald Holton, professor of physics and the history of science, Harvard University; coeditor, Einstein for the 21st Century: His Legacy in Science, Art and Modern Culture, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Structured serendipity
We overly-attribute breakthroughs to luck. But successful people regularly put themselves in positions — by studying, relentlessly working, pursuing the truth — where they encounter luck.
“We should each invest a few hours a week in reading research that ostensibly has nothing to do with our day jobs, in a setting that has nothing to do with our day jobs, in a setting that has nothing in common with our regular workspaces.”
Jason Zweig, personal finance columnist, Wall Street Journal; author, Your Money and Your Brain, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Subselves and the modular mind
John Moss, EAM Investors
The belief that we have a single self is false. In fact, we have multiple identities, or “subselves.”
“Each of us has a set of functional subselves — one dedicated to getting along with our friends, one dedicated to self-protection, one dedicated to winning status, another to finding mates …”
Douglas T. Kenrick, social psychology professor, Arizona State University, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
TANSTAAFL
Samsung
“TANSTAAFL is the acronym for ‘There ain’t no such thing as a free lunch,’ a universal truth having broad and deep explanatory power in science and daily life. … In such cases, a lunch comes at reasonable cost, as determined by the grim but honest accounting of natural selection.”
Robert R. Provine, psychologist and neuroscientist, University of Maryland; author, Laughter: A Scientific Investigation, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Umwelt
Umwelt is the idea that we blindly accept the reality of the world around us.
“It would be useful if the concept of the umwelt were embedded in the public lexicon. It neatly captures that idea of limited knowledge, of unobtainable information, of unimagined possibilities.”
David Eagleman, neuroscientist, Baylor College of Medicine, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
Uncalculated risk
“We humans are terrible at dealing with probability. … Our irrational fears and inclinations are costly.”
We place too great a weight on the possibility of rare, major events occurring to us — for example, the lottery, or a plane crash — but not enough weight into the effects of lesser events.
“Making good decisions requires concentrated mental effort, and if we overdo it, we run the risk of being counterproductive through increased stress and wasted time. So it’s best to balance and play, and take healthy risks.”
Garrett Lisi, independent theoretical physicist, from This Will Make You Smarter: New Scientific Concepts to Improve Your Thinking
