WHAT WILL CHANGE EVERYTHING?
"What game-changing scientific ideas and developments do you expect to live to see?"

THE BREAKDOWN OF ALL COMPUTERS
Anton Zeilinger
(University of Vienna and Scientific Director, Institute of Quantum Optics and Quantum Information, Austrian Academy of Sciences)

Some day all semiconductors will break down and therefore all computers as, besides historic instruments, no computers exist today which are not based on semiconductor technology. The breakdown will be caused by a giant electromagnetic pulse (EMP) created by a nuclear explosion outside Earth's athmosphere. It will cover large areas on Earth up to the size of a continent. Where it will happen is unpredictable. But it will happen since it is extremely unlikely that we will be able to get rid of all nuclear weapons and the probabilty for it to happen at any given time will never be zero.

The implications of such an event will be enormous. If it happens to one of our technology based societies literally everything will break down. You will realize that none your phones does work. There is no way to find out via the internet what happened. Your car will not start anymore as it is also controlled by computer chips, unless you are lucky to own an antique car. Your local supermarket is unable to get new supplies.There will be no trucks operating anymore, no trains, no elctricity, no water supplies. Society will completely break down.


Edward Hopper - "Eleven a.m.", 1926

There will be small exceptions in those countries where military equipment has been hardened against EMPs making the army available for emergency relief. In some countries even some emergency civilian infrastructure has been hardened against EMPs. But these are exceptions as most governments simply ignore that danger.

INSIDE OUT: THE EPISTEMOLOGY OF EVERYTHING
Tor Nørretranders
(Science Writer; Consultant; Lecturer, Copenhagen; Author, The Generous Man)


Understanding that the outside world is really inside us and the inside world is really outside us will change everything. Both inside and outside. Why? "There is no out there out there", physicist John Wheeler said in his attempt to explain quantum physics. All we know is how we correlate with the world. We do not really know what the world is really like, uncorrelated with us. When we seem to experience an external world that is out there, independent of us, it is something we dream up. Modern neurobiology has reached the exact same conclusion. The visual world, what we see, is an illusion, but then a very sophisticated one. There are no colours, no tones, no constancy in the "real" world, it is all something we make up. We do so for good reasons and with great survival value. Because colors, tones and constancy are expressions of how we correlate with the world.

The merging of the epistemological lesson from quantum mechanics with the epistemological lesson from neurobiology attest to a very simple fact: What we percieve as being outside of us is indeed a fancy and elegant projection of what we have inside. We do make this projection as as result of interacting with something not inside, but everything we experience is inside. Is it not real? It embodies a correlation that is very real. As physicist N. David Mermin has argued, we do have correlations, but we do not know what it is that correlates, or if any correlata exists at all. It is a modern formulation of quantum pioneer Niels Bohr's view: "Physics is not about nature, it is about what we can say about nature".



So what is real, then? Inside us humans a lot of relational emotions exists. We feel affection, awe, warmth, glow, mania, belonging and refusal towards other humans and to the world as a whole. We relate and it provokes deep inner emotional states. These are real and true, inside our bodies and percieved not as "real states" of the outside world, but more like a kind of weather phenomena inside us. That raises the simple question: Where do these internal states come from? Are they an effect of us? Did we make them or did they make us? Love exists before us (most of us were conceived in an act of love). Friendship, family bonds, hate, anger, trust, distrust, all of these entities exist before the individual. They are primary. The illusion of the ego denies the fact that they are there before the ego consciously decided to love or hate or care or not. But the inner states predate the conscious ego. And they predate the bodily individual.

The emotional states inside us are very, very real and the product of biological evolution. They are helpful to us in our attempt to survive. Experimental economics and behavioral sciences have recently shown us how important they are to us as social creatures: To cooperate you have to trust the other party, even though a rational analysis will tell you that both the likelihood and the cost of being cheated is very high. When you trust, you experience a physiologically detectable inner glow of pleasure. So the inner emotional state says yes. However, if you rationally consider the objects in the outside world, the other parties, and consider their trade-offs and motives, you ought to choose not to cooperate. Analyzing the outside world makes you say no. Human cooperation is dependent on our giving weight to what we experience as the inner world compared to what we experience as the outer world.



Traditionally, the culture of science has denied the relevance of the inner states. Now, they become increasingly important to understanding humans. And highly relevant when we want to build artefacts that mimic us. Soon we will be building not only Artificial Intelligence. We will be building Artificial Will. Systems with an ability to convert internal decisions and values into external change. They will be able to decide that they want to change the world. A plan inside becomes an action on the outside. So they will have to know what is inside and outside. In building these machines we ourselves will learn something that will change everything: The trick of perception is the trick of mistaking an inner world for the outside world. The emotions inside are the evolutionary reality. The things we see and hear outside are just elegant ways of imagining correlata that can explain our emotions, our correlations. We don't hear the croak, we hear the frog.

When we understand that the inner emotional states are more real than what we experience as the outside world, cooperation becomes easier. The epoch of insane mania for rational control will be over. What really changes is they way we see things, the way we experience everything. For anything to change out there you have to change everything in here. That is the epistemological situation. All spiritual traditions have been talking about it. But now it grows from the epistemology of quantum physics, neurobiology and the building of robots. We will be sitting there, building those Artificial Will-robots. Suddenly we will start laughing. There is no out there out there. It is in here. There is no in here in here. It is out there. The outside is in here. Who is there?

That laughter will change everything.

CULTURE
Timothy Taylor
(Archaeologist, University of Bradford; Author, The Buried Soul)

Culture changes everything because culture contains everything, in the sense of things that can be named, and so what can be conceived. Wittgenstein implied that what cannot be said cannot be thought. He meant by this that language relies on a series of prior agreements. Such grammar has been shown by anthropologists to underpin the idea of any on-going community, not just its language, but its broader categories, its institutions, its metaphysics. And the same paradox is presented: how can anything new ever happen? If by 'happen' we only think of personal and historical events, we miss the most crucial novelty—the way that new things, new physical objects, devices and techniques, insinuate themselves into our lives. They have new names which we must learn, and new, revolutionary effects.

It does not always work like that. Resistance is common. Paradoxically, the creative force of culture also tries to keep everything the same. Ernest Gellner said that humans, taken as a whole, present the most extensive behavioural variation of any species while every particular cultural community is characterized by powerful norms. These are ways of being that, often through appeals to some apparently natural order, are not just mildly claimed as quintessentially human, but lethally enforced at a local level, in a variety of more or less public ways. Out groups (whether a different ethnicity, class, sexuality, creed, whether being one of twins, an albino, someone disabled or an unusually talented individual) are suspect and challenging in their abnormality. Categories of special difference are typical foci for sacrifice, banishment, and ridicule through which the in-group becomes not just the in-group but, indeed, a distinctly perceptible group, confident, refreshed and culturally reproductive. This makes some sense: aberrance subverts the grammar of culture.

The level at which change can be tolerated varies greatly across social formations, but there is always a point beyond which things become intolerably incoherent. We may rightly label the most unprecedented behaviour mad because, whatever relativization might be invoked to explain it, it is, by definition, strategically doomed: we seek to ignore it. Yet the routine expulsion of difference, apparently critical in the here and now, becomes maladaptive in any longer-term perspective. Clearly, it is change that has created our species' resilience and success, creating the vast inter- (not intra-) cultural diversity that Gellner noted. So how does change happen?

Major change often comes stealthily. Its revolutionary effect may often reside in the very fact that we do not recognize what it is doing to our behaviour, and so cannot resist it. Often we lack to words to articulate resistance as the invention is a new noun whose verbal effect lags in its wake. Such major change operates far more effectively through things than directly through people, not brought about by the mad, but rather by 'mad scientists', whose inventions can be forgiven their inventors.

Unsurprisingly then, the societies that tolerate the least behavioural deviance are the most science-averse. Science, in the broadest sense of effective material invention, challenges quotidian existence. The Amish (a quaint static ripple whose way of life will never uncover the simplest new technological fix for the unfolding hazards of a dynamic universe) have long recognized that material culture embodies weird inspirations, challenging us, as eventual consumers, not with 'copy what I do', but a far, far more subversive 'try me.'

Material culture is the thing that makes us human, driving human evolution from the outset with its continually modifying power. Our species' particular dilemma is that in order to safeguard what we have, we have continually to change. The culture of things—invention and technology—is ever changing under the tide of words and routines whose role is to image fixity and agreement when, in reality, none exists. This form of change is no trivial thing because it is essential to our longer term survival. At least, the longer term survival of anything we may be proud to call universally human.

CRACKING OPEN THE LOCKBOX OF TALENT
Howard Gardner,
(Psychologist, Harvard Graduate School of Education; Author, Five Minds for the Future)

What is talent? If you ask the average grade school teacher to identify her most talented student, she is likely to reject the question: "All my students are equally talented." But of course, this answer is rubbish. Anyone who has worked with numerous young people over the years knows that some catch on quickly, almost instantly, to new skills or understandings, while others must go through the same drill, with little depressingly little improvement over time.

As wrongheaded as the teacher's response is the viewpoint put forward by some psychological researchers, and most recently popularized in Malcolm Gladwell's Outliers: The Story of Success. This is notion that there is nothing mysterious about talent, no need to crack open the lockbox: anyone who works hard enough over a long period of time can end up at the top of her field. Anyone who has the opportunity to observe or read about a prodigy—be it Mozart or Yo-Yo Ma in music, Tiger Woods in golf, John von Neumann in mathematics—knows that achievement is not just hard work: the differences between performance at time 1 and successive performances at times 2, 3, and 4 are vast, not simply the result of additional sweat. It is said that if algebra had not already existed,, precocious Saul Kripke would have invented it in elementary school: such a characterization would be ludicrous if applied to most individuals.

For the first time, it should be possible to delineate the nature of talent. This breakthrough will come about through a combination of findings from genetics (do highly talented individuals have a distinctive, recognizable genetic profile?); neuroscience (are there structural or functional neural signatures, and, importantly, can these be recognized early in life?); cognitive psychology (are the mental representations of talented individuals distinctive when contrasted to those of hard workers); and the psychology of motivation (why are talented individuals often characterized as having 'a rage to learn, a passion to master?)

This interdisciplinary scientific breakthrough will allow us to understand what is special about Picasso, Gauss, J.S. Mill. Importantly, it will illuminate whether a talented person could have achieved equally in different domains (could Mozart have been a great physicist? Could Newton have been a great musician?) Note, however, that will not illuminate two other issues:

1. What makes someone original, creative? Talent, expertise,
are necessary but not sufficient.
2. What determines whether talents are applied to constructive
or destructive ends?

These answers are likely to come from historical or cultural case studies, rather than from biological or psychological science. Part of the maturity of the sciences is an appreciation of which questions are best left to other disciplinary approaches.

RELATIVISM
Timothy Taylor (archaeologist, University of Bradford;
author, The Buried Soul)




Where once I would have striven to see Incan child sacrifice 'in their terms', I am increasingly committed to seeing it in ours. Where once I would have directed attention to understanding a past cosmology of equal validity to my own, I now feel the urgency to go beyond a culturally-attuned explanation and reveal cold sadism, deployed as a means of social control by a burgeoning imperial power.

In Cambridge at the end of the 70s, I began to be inculcated with the idea that understanding the internal logic and value system of a past culture was the best way to do archaeology and anthropology. The challenge was to achieve this through sensitivity to context, classification and symbolism. A pot was no longer just a pot, but a polyvalent signifier, with a range of case-sensitive meanings. A rubbish pit was no longer an unproblematic heap of trash, but a semiotic entity embodying concepts of contagion and purity, sacred and profane. A ritual killing was not to be judged bad, but as having validity within a different worldview.



Using such 'contextual' thinking, a lump of slag found in a 5000 BC female grave in Serbia was no longer seen as chance contaminant — bi-product garbage from making copper jewelry. Rather it was a kind of poetic statement bearing on the relationship between biological and cultural reproduction. Just as births in the Vinca culture were attended by midwives who also delivered the warm but useless slab of afterbirth, so Vinca culture ore was heated in a clay furnace that gave birth to metal. From the furnace — known from many ethnographies to have projecting clay breasts and a graphically vulvic stoking opening — the smelters delivered technology's baby. With it came a warm but useless lump of slag. Thus the slag in a Vinca woman's grave, far from being accidental trash, hinted at a complex symbolism of gender, death and rebirth.

So far, so good: relativism worked as a way towards understanding that our industrial waste was not theirs, and their idea of how a woman should be appropriately buried not ours. But what happens when relativism says that our concepts of right and wrong, good and evil, kindness and cruelty, are inherently inapplicable? Relativism self-consciously divests itself of a series of anthropocentric and anachronistic skins — modern, white, western, male-focused, individualist, scientific (or 'scientistic') — to say that the recognition of such value-concepts is radically unstable, the 'objective' outsider opinion a worthless myth.

My colleague Andy Wilson and our team have recently examined the hair of sacrificed children found on some of the high peaks of the Andes. Contrary to historic chronicles that claim that being ritually killed to join the mountain gods was an honour that the Incan rulers accorded only to their own privileged offspring, diachronic isotopic analyses along the scalp hairs of victims indicate that it was peasant children, who, twelve months before death, were given the outward trappings of high status and a much improved diet to make them acceptable offerings. Thus we see past the self-serving accounts of those of the indigenous elite who survived on into Spanish rule. We now understand that the central command in Cuzco engineered the high-visibility sacrifice of children drawn from newly subject populations. And we can guess that this was a means to social control during the massive, 'shock & awe' style imperial expansion southwards into what became Argentina.



But the relativists demur from this understanding, and have painted us as culturally insensitive, ignorant scientists (the last label a clear pejorative). For them, our isotope work is informative only as it reveals 'the inner fantasy life of, mostly, Euro-American archaeologists, who can't possibly access the inner cognitive/cultural life of those Others.' The capital 'O' is significant. Here we have what the journalist Julie Burchill mordantly unpacked as 'the ever-estimable Other' — the albatross that post-Enlightenment and, more importantly, post-colonial scholarship must wear round its neck as a sign of penance.

We need relativism as an aid to understanding past cultural logic, but it does not free us from a duty to discriminate morally and to understand that there are regularities in the negatives of human behaviour as well as in its positives. In this case, it seeks to ignore what Victor Nell has described as 'the historical and cross-cultural stability of the uses of cruelty for punishment, amusement, and social control'. By denying the basis for a consistent underlying algebra of positive and negative, yet consistently claiming the necessary rightness of the internal cultural conduct of 'the Other', relativism steps away from logic into incoherence.

WE DIFFER MORE THAN WE THOUGHT
Mark Pagel (evolutionary biologist, Reading University, England)



The last thirty to forty years of social science has brought an overbearing censorship to the way we are allowed to think and talk about the diversity of people on Earth. People of Siberian descent, New Guinean Highlanders, those from the Indian sub-continent, Caucasians, Australian aborigines, Polynesians, Africans — we are, officially, all the same: there are no races.

Flawed as the old ideas about race are, modern genomic studies reveal a surprising, compelling and different picture of human genetic diversity. We are on average about 99.5% similar to each other genetically. This is a new figure, down from the previous estimate of 99.9%. To put what may seem like miniscule differences in perspective, we are somewhere around 98.5% similar, maybe more, to chimpanzees, our nearest evolutionary relatives.


Índios Mojave

The new figure for us, then, is significant. It derives from among other things, many small genetic differences that have emerged from studies that compare human populations. Some confer the ability among adults to digest milk, others to withstand equatorial sun, others yet confer differences in body shape or size, resistance to particular diseases, tolerance to hot or cold, how many offspring a female might eventually produce, and even the production of endorphins — those internal opiate-like compounds. We also differ by surprising amounts in the numbers of copies of some genes we have.


Cabeça de um negro - Albrecht Dürer

Modern humans spread out of Africa only within the last 60-70,000 years, little more than the blink of an eye when stacked against the 6 million or so years that separate us from our Great Ape ancestors. The genetic differences amongst us reveal a species with a propensity to form small and relatively isolated groups on which natural selection has often acted strongly to promote genetic adaptations to particular environments.

We differ genetically more than we thought, but we should have expected this: how else but through isolation can we explain a single species that speaks at least 7,000 mutually unintelligible languages around the World?


Huang-Ti, o imperador amarelo (China)

What this all means is that, like it or not, there may be many genetic differences among human populations — including differences that may even correspond to old categories of 'race' — that are real differences in the sense of making one group better than another at responding to some particular environmental problem. This in no way says one group is in general 'superior' to another, or that one group should be preferred over another. But it warns us that we must be prepared to discuss genetic differences among human populations. (WHAT HAVE YOU CHANGED YOUR MIND ABOUT? WHY?)

THE NATURE OF HUMAN NATURE
Michael Shermer (publisher of "Skeptic magazine", monthly columnist for "Scientific American"; author, Why Darwin Matters)



When I was a graduate student in experimental psychology I cut my teeth in a Skinnerian behavioral laboratory. As a behaviorist I believed that human nature was largely a blank slate on which we could impose positive and negative reinforcements (and punishments if necessary) to shape people and society into almost anything we want. As a young college professor I taught psychology from this perspective and even created a new course on the history and psychology of war, in which I argued that people are by nature peaceful and nonviolent, and that wars were thus a byproduct of corrupt governments and misguided societies.

The data from evolutionary psychology has now convinced me that we evolved a dual set of moral sentiments: within groups we tend to be pro-social and cooperative, but between groups we are tribal and xenophobic. Archaeological evidence indicates that Paleolithic humans were anything but noble savages, and that civilization has gradually but ineluctably reduced the amount of within-group aggression and between group violence. And behavior genetics has erased the tabula rasa and replaced it with a highly constrained biological template upon which the environment can act.

I have thus changed my mind about this theory of human nature in its extreme form. Human nature is more evolutionarily determined, more cognitively irrational, and more morally complex than I thought. (WHAT HAVE YOU CHANGED YOUR MIND ABOUT? WHY?)
