This is a proposal for the re-activation of the essentially stillborn automatic car project for which the cart was originally obtained, and presents a process through which this activation could be accomplished painlessly. The project would be financed from the lab's operating grant, and would interact strongly with, while being independent of, any Mars rover research initiated by Lynn Quam. Since I seem to be the only one, apart from John McCarthy, with an active interest in this aspect of things, (...) the following is written entirely from my point of view. (shrink)

The thoughts presented here never appeared in research proposals, but nevertheless grew at the Stanford University Artificial Intelligence Laboratory over the years 1971 through 1980 under support from the National Institutes of Health, the Defense Advanced Research Projects Agency, the National Science Foundation and the National Aeronautics and Space Administration, and more recently at the Carnegie-Mellon University Robotics Institute under Office of Naval Research contract number N00014-81-K-0503.

Serious attempts to build thinking machines began after the second world war. One line of research, called Cybernetics, used electronic circuitry imitating nervous systems to make machines that learned to recognize simple patterns, and turtle-like robots that found their way to recharging plugs. A different approach, named Artificial Intelligence, harnessed the arithmetic power of post-war computers to abstract reasoning, and by the 1960s made computers prove theorems in logic and geometry, solve calculus problems and play good games of checkers. At (...) the end of the 1960s, research groups at MIT and Stanford attached television cameras and robot arms to their computers, so "thinking" programs could begin to collect information directly from the real world.

Following the cart meeting of June 13, in which it was agreed that McCarthy would buy the cart project a TV transmitter if I could demonstrate my ability to do work on vision by writing a program which extracted three dimensional information from a motion stereo sequence of pictures, I began work on this task. So that there would be no doubt as to who had done the work, and because I operate most comfortably and effectively in a programming environment (...) made to my own tastes, the first order of business was the writing of a set of graphics and picture utility routines. The resulting package provides more flexibility than Quam's III buffer based routines, and is more cohesive than Baumgart's set, which is spread out among several programs. Currently the package accesses Data Disc displays only, in future it will be extended to provide output to the XGP and maybe the III's. As an example of increased capabilities, it allows display of filled in polygons, and permits displays to be shrunk or expanded arbitrarily merely by changing the declared dimensions of the screen or the requested sizes of the individual parts. Also, selected areas of the display may be erased or complemented, as well as added to. The programs described below use no previously existing software other than the FAIL and SAIL compilers and the operating system. (shrink)

Our first tools, sticks and stones, were very different from ourselves. But many tools now resemble us, in function or form, and they are beginning to have minds. A loose parallel with our own evolution suggests how they may develop in future. Computerless industrial machinery exhibits the behavioral flexibility of single-celled organisms. Today's best computer-controlled robots are like the simpler invertebrates. A thousand-fold increase in computer power in this decade should make possible machines with reptile-like sensory and motor competence. Growing (...) computer power over the next half century will allow robots that learn like mammals, model their world like primates and eventually reason like humans. Depending on your point of view, humanity will then have produced a worthy successor, or transcended inherited limitations and transformed itself into something quite new. No longer limited by the slow pace of human learning and even slower biological evolution, intelligent machinery will conduct its affairs on an ever faster, ever smaller scale, until coarse physical nature has been converted to fine-grained purposeful thought.

In this article the question is raised whether artificial intelligence has any psychological relevance, i.e. contributes to our knowledge of how the mind/brain works. It is argued that the psychological relevance of artificial intelligence of the symbolic kind is questionable as yet, since there is no indication that the brain structurally resembles or operates like a digital computer. However, artificial intelligence of the connectionist kind may have psychological relevance, not because the brain is a neural network, but because connectionist networks (...) exhibit operating characteristics which mimic operant behavior. Finally it is concluded that, since most of the work done so far in AI and Law is of the symbolic kind, it has as yet contributed little to our understanding of the legal mind. (shrink)

This paper examines the paradoxical transparency involved in training machine-learning models. Existing literature typically critiques the opacity of machine-learning models such as neural networks or collaborative filtering, a type of critique that parallels the black-box critique in technology studies. Accordingly, people in power may leverage the models’ opacity to justify a biased result without subjecting the technical operations to public scrutiny, in what Dan McQuillan metaphorically depicts as an “algorithmic state of exception”. This paper attempts to differentiate the black-box abstraction (...) that wraps around complex computational systems from the opacity of machine-learning models. It contends that the degree of asymmetry in knowledge is greater in the former than the latter. In the case of software systems, software codes are difficult to understand as only software experts with sufficient domain knowledge are equipped to formulate a sound critique. In contrast, the meanings of trained parameters in a machine-learning model are obscure even to the data scientists who configure and train the model. Hence, the asymmetry of knowledge lies only in how data examples are collected, the choice and configuration of machine-learning models, and the specification of features in model design. Under the trend of algorithmic decision-making proliferating with machine-learning heuristics, the paper contends that the more symmetric distribution of knowledge in machine learning could lead to a more transparent production process if proper policies are in place.

The current literature in artificial intelligence and robotics awareness focused on the dark side of AIRA. Accordingly, this study sheds light on the positive effect of AIRA on employee creativity by exploring how and when hotel employees may take proactive behavior facing the threat of AI and robotics to further stimulate creativity. Based on the work adjustment theory and the locus of control theory, this study constructs a moderating multiple mediation model to explain the influence of AIRA on employee creativity, (...) in which active learning and task crafting are used as mediating variables, and locus of control is used as moderating variable. Data collected from 264 employees in a Chinese hotel are used for empirical analysis. Results show that AIRA indirectly positively affects employee creativity via active learning and task crafting and Locus of control not only moderates the mediating effect of active learning between the relationship of AIRA and employee creativity but also moderates the mediating effect of task crafting between the relationship of AIRA and employee creativity. The theoretical and practical implications are discussed. (shrink)

Some stories of moral exemplars motivate us to emulate their admirable attitudes and behaviors, but why do some exemplars motivate us more than others? We systematically studied how motivation to emulate is influenced by the similarity between a reader and an exemplar in social or cultural background (Relatability) and how personally costly or demanding the exemplar’s actions are (Attainability). Study 1 found that university students reported more inspiration and related feelings after reading true stories about the good deeds of a (...) recent fellow alum, compared to a famous moral exemplar from decades past. Study 2A developed a battery of short moral exemplar stories that more systematically varied Relatability and Attainability, along with a set of non-moral exemplar stories for comparison. Studies 2B and 2C examined the path from the story type to relatively low stakes altruism (donating to charity and intentions to volunteer) through perceived attainability and relatability, as well as elevation and pleasantness. Together, our studies suggest that it is primarily the relatability of the moral exemplars, not the attainability of their actions, that inspires more prosocial motivation, at least regarding acts that help others at a relatively low cost to oneself.

Machines will attain human levels of intelligence by the year 2040, predicts robotics expert Hans Moravec. And by 2050, they will have far surpassed us. In this mind-bending new book, Hans Moravec takes the reader on a roller coaster ride packed with such startling predictions. He tells us, for instance, that in the not-too-distant future, an army of robots will displace workers, causing massive, unprecedented unemployment. But then, says Moravec, a period of very comfortable existence (...) will follow, as humans benefit from a fully automated economy. And eventually, as machines evolve far beyond humanity, robots will supplant us. But if Moravec predicts the end of the domination by human beings, his is not a bleak vision. Far from railing against a future in which machines rule the world, Moravec embraces it, taking the startling view that intelligent robots will actually be our evolutionary heirs. "Intelligent machines, which will grow from us, learn our skills, and share our goals and values, can be viewed as children of our minds." And since they are our children, we will want them to outdistance us. In fact, in a bid for immortality, many of our descendants will choose to transform into "ex humans," as they upload themselves into advanced computers. We will become our children and live forever. In his provocative new book, the highly anticipated follow-up to his bestselling volume Mind Children, Moravec charts the trajectory of robotics in breathtaking detail. A must read for artificial intelligence, technology, and computer enthusiasts, Moravec's freewheeling but informed speculations present a future far different than we ever dared imagine. (shrink)

On 8th August 2019, Secretary of State for Health and Social Care, Matt Hancock, announced the creation of a £250 million NHS AI Lab. This significant investment is justified on the belief that transforming the UK’s National Health Service (NHS) into a more informationally mature and heterogeneous organisation, reliant on data-based and algorithmically-driven interactions, will offer significant benefit to patients, clinicians, and the overall system. These opportunities are realistic and should not be wasted. However, they may be missed (one may (...) recall the troubled Care.data programme) if the ethical challenges posed by this transformation are not carefully considered from the start, and then addressed thoroughly, systematically, and in a socially participatory way. To deal with this serious risk, the NHS AI Lab should create an Ethics Advisory Board and monitor, analyse, and address the normative and overarching ethical issues that arise at the individual, interpersonal, group, institutional and societal levels in AI for healthcare.

Computers have far to go to match human strengths, and our estimates will depend on analogy and extrapolation. Fortunately, these are grounded in the first bit of the journey, now behind us. Thirty years of computer vision reveals that 1 MIPS can extract simple features from real-time imagery--tracking a white line or a white spot on a mottled background. 10 MIPS can follow complex gray-scale patches--as smart bombs, cruise missiles and early self-driving vans attest. 100 MIPS can follow moderately unpredictable (...) features like roads--as recent long NAVLAB trips demonstrate. 1,000 MIPS will be adequate for coarse-grained three-dimensional spatial awareness--illustrated by several mid-resolution stereoscopic vision programs, including my own. 10,000 MIPS can find three-dimensional objects in clutter--suggested by several "bin-picking" and high-resolution stereo-vision demonstrations, which accomplish the task in an hour or so at 10 MIPS. The data fades there--research careers are too short, and computer memories too small, for significantly more elaborate experiments. (shrink)

Exploration and colonization of the universe await, but Earth‐adapted biological humans are ill equipped to respond to the challenge. Machines have gone farther and seen more, limited though they presently are by insect‐like behavioral inflexibility.

The unprecedented opportunities for experiments in complexity presented by the first modern computers in the late 1940's raised hopes in early computer scientists (eg. John von Neumann and Alan Turing) that the ability to think, our greatest asset in our dealings with the world, might soon be understood well enough to be duplicated. Success in such an endeavor would extend mankind's mind in the same way that the development of energy machinery extended his muscles.

In recent years the mushrooming power, functionality and ubiquity of computers and the Internet have outstripped early forecasts about technology's rate of advancement and usefulness in everyday life. Alert pundits now foresee a world saturated with powerful computer chips, which will increasingly insinuate themselves into our gadgets, dwellings, apparel and even our bodies.

The last few years have been good for time machines. Kip Thorne's renowned general relativity group at Caltech invented a new quantum gravitational approach to building a time gate, and, in an international collaboration, gave a plausible rebuttal of "grandfather paradox" arguments against time travel. Another respected group suggested time machines that exploit quantum mechanical time uncertainty. The technical requirements for these suggestions exceed our present capabilities, but each new approach seems less onerous than the last. There is hope yet (...) that time travel will eventually become possible, even cheap. (shrink)

Folk psychology is under threat - that is to say - our everyday conception that human beings are agents who experience the world in terms of sights, sounds, tastes, smells and feelings and who deliberate, make plans, and generally execute actions on the basis of their beliefs, needs and wants - is under threat. This threat is evidenced in intellectual circles by the growing attitude amongst some cognitive scientists that our common sense categories are in competition with connectionist theories and (...) modern neuroscience. It is often thought that either folk psychology or modern cognitive science must go. It is in these terms that the battle lines of today's philosophy of mind are drawn. (shrink)

This paper describes some components of a working system which drives a vehicle through cluttered real world environments under computer control, guided by images perceived through an onboard television camera. The emphasis is on reliable and fast low level visual techniques which determine the existence and location of objects in the world, but do not identify them. They include an interest operator for choosing distinctive regions in images, a correlator for finding matching regions in similar images, a geometric camera solver (...) which determines camera displacement and distance to objects from motion stereo information and an automatic distortion corrector which compensates for camera imperfections.

Exploration and colonization of the universe awaits, but earth-adapted biological humans are ill-equipped to respond to the challenge. Machines have gone farther and seen more, limited though they presently are by insect-like behavioral inflexibility. As they become smarter over the coming decades, space will be theirs. Organizations of robots of ever increasing intelligence and sensory and motor ability will expand and transform what they occupy, working with matter, space and time. As they grow, a smaller and smaller fraction of their (...) territory will be undeveloped frontier. Competitive success will depend more and more on using already available matter and space in ever more refined and useful forms. The process, analogous to the miniaturization that makes today's computers a trillion times more powerful than the mechanical calculators of the past, will gradually transform all activity from grossly physical homesteading of raw nature, to minimum-energy quantum transactions of computation. The final frontier will be urbanized, ultimately into an arena where every bit of activity is a meaningful computation: the inhabited portion of the universe will transformed into a cyberspace.

Chapter 7 of Robot was my first presentation of a surprising chain of reasoning. I wanted to rewrite it, but didn't have the energy in time for publication. Now that the pressure is off, and my visceral comfort with the ideas has risen, I'd like to present them more compellingly. This piece is a start.

The basic terminal is externally a box with a keyboard and some connectors and a few lights and switches. The connectors are for power, modem or phone line, video out, audio out, rf out (audio and video modulated onto a tv carrier), I/O bus (or unibus). It should be as light and compact as possible.

Computers have invaded everyday life, and networked machines are worming their way into our gadgets, dwellings, clothes, even bodies. But if pervasive computing soon handles most of our information needs, it will still not clean the floors, take out the garbage, assemble kit furniture or do any of a thousand other other essential physical tasks. The old dream of mechanical servants will remain mostly unmet.

Computers were invented recently to mechanize tedious manual informational procedures. Such procedures were themselves invented only during the last ten millennia, as agricultural civilizations outgrew village-scale social instincts. The instincts arose in our hominid ancestors during several million years of life in the wild, and were themselves built on perceptual and motor mechanisms that had evolved in a vertebrate lineage spanning hundreds of millions of years.

Bedazzled by the explosion of computers into everyday life, pundits predict a world saturated by communicating chips, in our gadgets, dwellings, clothes, even bodies. But if pervasive computing handles most of our information needs, it will still not clean the floors, take out the garbage, assemble kit furniture or do any of a thousand other other essential physical tasks. The old dream of mechanical servants will remain unmet.

After decades of commercial stagnation, robotics seems to be at a turning point. A half dozen companies have introduced small domestic robot vacuum cleaners, with sufficient market success to fuel the development of more advanced follow-ons. Hundreds of thousands of Sony's advanced AIBO..

The evidence grid representation was formulated at the CMU Mobile Robot Laboratory in 1983 to turn wide angle range measurements from cheap mobile robot-mounted sonar sensors into detailed spatial maps. It accumulates diffuse evidence about the occupancy of a grid of small volumes of nearby space from individual sensor readings into increasingly confident and detailed maps of a robot's surroundings. It worked surprisingly well in first implementation for sonar navigation in cluttered rooms. In the past decade its use has been (...) extended to range measurements from stereoscopic vision and other sensors, sonar in very difficult specular environments, and other contexts. The most dramatic extension yet, from 2D grid maps with thousands of cells to 3D grids with millions, is underway. (shrink)

In the early 1970s, doing simple computer stereoscopic vision, it became rapidly obvious that the computer power in our mainframe PDP-10 was hugely insufficient to do even that basic function in real time, implying that doing the job of the whole nervous system was even further out of reach. Besides enormously more speed, we needed enormously more memory.

Very encouraging results have been obtained from a new program that derives a dense three-dimensional evidence grid representation of a robot's surroundings from wide-angle stereoscopic images. The pro gram adds several spatial rays of evidence to a grid for each of about 2,500 local image features chosen per stereo pair. It was used to construct a 256x256x64 grid, representing 6 by 6 by 2 meters, from a hand- collected test set of twenty stereo image pairs of an office scene. Fifty (...) nine stereo pairs of an 8 by 8 meter laboratory were also processed. The positive (probably occupied) cells of the grids, viewed in perspec tive, resemble dollhouse scenes. Details as small as the curvature of chair armrests are discernible. The processing time, on a 100 MIPS Sparc 20, is less than five seconds per stereo pair, and total memory is under 16 megabytes. The results seem abundantly adequate for very reliable navigation of freely roaming mobile robots, and plausibly adequate for shape identification of objects bigger than 10 centimeters. The program is a first proof of concept, and awaits optimizations, enhancements, variations, extensions and applications. (shrink)

The most consistently interesting stories are those about journeys, and the most fascinating organisms are those that move from place to place. I think these observations are more than idiosyncrasies of human psychology, but illustrate a fundamental principle. The world at large has great diversity, and a traveller constantly encounters novel circumstances, and is consequently challenged to respond in new ways. Organisms and mechanisms do not exist in isolation, but are systems with their environments, and those on the prowl in (...) general have a richer environment than those rooted to one place.

The project is funded by the Office of Naval Research under a contract entiltled Underwater Robots. The effort is interesting in its own right, and complements projects involving underwater vehicles such as those at the University of New Hampshire and the Naval Ocean Systems Center in San Diego. These other efforts are interesting to us, but we feel they are incomplete. Their current control systems are very simple, typically incorporating quite small programs on one or a few microprocessors and implementing (...) simple dead reckoning navigation or terrain following behavior.

Senses evolved to when the world was wild, enabling our ancestors to detect subtle passing opportunities and dangers. Senses are less useful in a tamer world, where our interactions become more and more simple information exchanges. Senses, and the instincts using them, are increasingly liabilities, demanding entertainment rather than providing useful services. The anachronism will become more apparent as virtual realities, prosthetic sense organs and brain to computer interfaces become common. Imagine reading a computer screen if your eyes and visual (...) cortex are artificial prostheses. It would be far better to bypass all the sensory processing, and insert the message from the computer directly into the thinking portions of your brain. In such manner all our senses will become obsolete, as our physical environment is inexorably refined from a rough physical place into a densely interconnected cyberspace. (shrink)

We chart how neuroscience and philosophy have together advanced our understanding of moral judgment with implications for when it goes well or poorly. The field initially focused on brain areas associated with reason versus emotion in the moral evaluations of sacrificial dilemmas. But new threads of research have studied a wider range of moral evaluations and how they relate to models of brain development and learning. By weaving these threads together, we are developing a better understanding of the neurobiology of (...) moral judgment in adulthood and to some extent in childhood and adolescence. Combined with rigorous evidence from psychology and careful philosophical analysis, neuroscientific evidence can even help shed light on the extent of moral knowledge and on ways to promote healthy moral development.

Summarizing a surrounding 200 pages, pages 179 to 190 of Shadows of the Mind contain a future dialog between a human identified as "Albert Imperator" and an advanced robot, the "Mathematically Justified Cybersystem", allegedly Albert's creation. The two have been discussing a Gödel sentence for an algorithm by which a robot society named SMIRC certifies mathematical proofs. The sentence, referred to in mathematical notation as Omega(Q*), is to be precisely constructed from on a definition of SMIRC's algorithm. It can be (...) interpreted as stating "SMIRC's algorithm cannot certify this statement." The robot has asserted that SMIRC never makes mistakes. If so, SMIRC's algorithm cannot certify the Goedel sentence, for that would make the statement false. But, if they can't certify it, what is says is true! Humans can understand it is true, but mighty SMIRC cannot certify it. The dialog ends melodramatically as the robot, apparently unhinged by this revelation, claims to be a messenger of god, and the human shuts it down with a secret control. (shrink)

The Evangelical Academies are a forum to open debate on any matters relating to a furtherance of a responsible approach to future directions in society. The contribution discusses in the author's view in which way, for which reasons and on which sociallevels questions of ethics in economy have occured in the Academie's work. The author proposes to establish interdisciplinary teams developing norms to connect ethics and economy, and points out a nurober of tasks for the future work.

Modern medicine, based on enormous progress in science and its applications, has lost dimensions of individualized treatment and compassion which traditionally were an essential part of physician’s service over the millennia in Eastern and Western cultures. Today diseases and symptoms, rather than persons, are treated, based on objective quality norms and inflexible payment schemes rather than the rather than persons. We present a checklist model for personalized health care, which has been successful in teaching and practice to reclaim lost territory (...) in treating patients as persons. (shrink)

This paper explores the influence of Henri Bergson’s (1859–1941) philosophy of time on three early twentieth-century British philosophers: Karin Costelloe-Stephen (1889–1953), Hilda Oakeley (1867–1950), and May Sinclair (1863–1946). I demonstrate that three central claims of Bergson’s account of temporal experience (novelty, memory, and indivisibility) were creatively incorporated into their accounts of time. All these philosophers place time at the centre of their philosophical systems, so this study of their views on time and temporality can deepen our understanding of their systems (...) more broadly. Further, this study helps us appreciate the reception of Bergson’s thought in British philosophy after it was ferociously attacked by Bertrand Russell in 1912, and can provide more detailed contours on the joint fortunes of temporal experience and Bergson's thought in the history of twentieth-century philosophy. I conclude by emphasizing reasons why contemporary philosophers should pay particular attention to the three figures’ treatment of Bergson. (shrink)

We present a theoretical and an empirical challenge to Cushman's claim that rationalization is adaptive because it allows humans to extract more accurate beliefs from our non-rational motivations for behavior. Rationalization sometimes generates more adaptive decisions by making our beliefs about the world less accurate. We suggest that the most important adaptive advantage of rationalization is instead that it increases our predictability as potential partners in cooperative social interactions.

In some languages every statement must contain a specification of the type of evidence on which it is based: for example, whether the speaker saw it, or heard it, or inferred it from indirect evidence, or learnt it from someone else. This grammatical reference to information source is called 'evidentiality', and is one of the least described grammatical categories. Evidentiality systems differ in how complex they are: some distinguish just two terms (eyewitness and noneyewitness, or reported and everything else), while (...) others have six or even more terms. Evidentiality is a category in its own right, and not a subcategory of epistemic or some other modality, nor of tense-aspect. Every language has some way of referring to the source of information, but not every language has grammatical evidentiality. In English expressions such as I guess, they say, I hear that, the alleged are not obligatory and do not constitute a grammatical system. Similar expressions in other languages may provide historical sources for evidentials. True evidentials, by contrast, form a grammatical system. In the North Arawak language Tariana an expression such as "the dog bit the man" must be augmented by a grammatical suffix indicating whether the event was seen, or heard, or assumed, or reported. This book provides the first exhaustive cross-linguistic typological study of how languages deal with the marking of information source. Examples are drawn from over 500 languages from all over the world, several of them based on the author's original fieldwork. Professor Aikhenvald also considers the role evidentiality plays in human cognition, and the ways in which evidentiality influences human perception of the world.. This is an important book on an intriguing subject. It will interest anthropologists, cognitive psychologists and philosophers, as well as linguists. (shrink)

In the concluding chapter of Exceeding our Grasp Kyle Stanford outlines a positive response to the central issue raised brilliantly by his book, the problem of unconceived alternatives. This response, called "epistemic instrumentalism", relies on a distinction between instrumental and literal belief. We examine this distinction and with it the viability of Stanford's instrumentalism, which may well be another case of exceeding our grasp.

I contrast our own evidence for the hypothesis of organic fossil origins with that available in previous centuries, suggesting that the most powerful contemporary evidence consists in a form of projective support whose distinctive features are not well captured by familiar hypothetico-deductive, abductive, or even more recent and more technically sophisticated accounts of scientific confirmation. I suggest that such accounts either misrepresent or ignore something important about the heterogeneous ways in which scientific hypotheses can be supported by evidence, and I (...) go on to suggest that the search for any single such account may be misguided in any case.

The cell theory of Schleiden and Schwann is generalized to the effect that throughout the natural world, in physics, biology, and sociopsychology, there is a widespread phenomenon of the existence of organized cells, whose organization is usually protected by barriers. These barriers exist not only in space, but in time and even in other domains. These barriers typically not only protect the organization within the cell from external disturbance, but they actively participate in reducing the internal disorganization. It appears that (...) the quantum phase cell or its equivalent, the discrete quantum state, may be a physical analog of the organized biological cell. The sampling and ambiguity theorems of communication theory throw new light on phase cells. The quantum phase cell has both configuration and momentum elements, which are analogous respectively to the somatic elements in the cytoplasm of a cell and the genetic elements in the DNA. A biological cell or organism, a physical quantum state, and a human being as a sociopsychological entity each has a natural individuality. A natural individuality is a somewhat mysterious thing, since in addition to specificity, it also involves stochasticity and complementarity. There are some striking and unexplained spin-analog characteristics in biology which have a relation to boson- and fermion-analog characteristics in biology that corresponds with the known relation in physics. The hypothesis suggested in our earlier paper, that quantum mechanical entropy is diminished in interaction, is clarified and sharpened in this paper. (shrink)

At the heart of the underdetermination of scientific theory by evidence is the simple idea that the evidence available to us at a given time may fail to determine what beliefs we should hold in response to it. In a textbook example, if I all I know is that you spent $10 on apples and oranges and that apples cost $1 while oranges cost $2, then I know that you did not buy six oranges, but I do not know whether (...) you bought one orange and eight apples, two oranges and six apples, and so on. A simple scientific example can be found in the rationale behind the sensible methodological adage that “correlation does not imply causation”. If watching lots of cartoons causes children to be more violent in their playground behavior then we should (barring complications) expect to find a correlation between levels of cartoon viewing and violent playground behavior. But that is also what we would expect to find if children who are prone to violence tend to enjoy and seek out cartoons more than other children, or if propensities to violence and increased cartoon viewing are both caused by some third factor (like general parental neglect or excessive consumption of jellybeans). So a high correlation between cartoon viewing and violent playground behavior is evidence that (by itself) simply underdetermines what we should believe about the causal relationship between these two activities. As we will see, however, the challenge of distinguishing correlation from causation is far from the only important circumstance in which underdetermination is thought to arise in scientific inquiry.
