Purpose. The research is devoted to the analysis of the urgent problem of the information society: the overload of a person with information and, as a result, the impossibility of adequate formation and development of the personality; as well as the problem of "digitization" of human existence and the formation of a new reality of dataism. Theoretical basis. A lot of modern scientific works are devoted to the analysis of the information society, its problems and features. The (...) information society is a logical continuation of the scientific and technological revolution, which led to the rapid growth of scientific knowledge and the technology development. In the 20th century, technologies have touched the sphere of knowledge and information, as a result of which the formation and development of the information society, or "knowledge society", takes place. Information becomes the main resource in it, and, one way or another, a person’s life is inextricably connected with the information space. With the information society formation, the problem of information search and processing becomes one of the most urgent. It turns out that despite the abundance and availability of information, it is very difficult to determine its relevance. A lot of effort is spent on developing information retrieval algorithms. Another problem is related to the person’s inability to process large amounts of data. This situation begins to influence not only the education process and professional activity, but also the formation of a person’s personality. A person is "lost" in the information space and gradually loses his/her "I". Algorithms for data analysis come to the rescue, but gradually, instead of giving a person material for thought, they begin to make decisions on their own, and therefore, live life instead of a person. With the advent of Big Data processing algorithms, a new ideological paradigm appears – dataism, which predicts the merger of a person with the general data flow. Originality. The authors make assumptions that the dataistic future is "natural". A lot of works, including in the framework of philosophy, are focused on the problem of "dissolving" a person in the information space and finding ways to overcome it. But, in our opinion, this process is a completely logical continuation of human evolution. Conclusions. Existence of a person as a data flow is not a problem and a threat, but a new dimension of his/her being, and, therefore, requires a careful study and formulation of the main principles of this form of existence.

Searching for information is critical in many situations. In medicine, for instance, careful choice of a diagnostic test can help narrow down the range of plausible diseases that the patient might have. In a probabilistic framework, test selection is often modeled by assuming that people's goal is to reduce uncertainty about possible states of the world. In cognitive science, psychology, and medical decision making, Shannon entropy is the most prominent and most widely used model to formalize probabilistic uncertainty and (...) the reduction thereof. However, a variety of alternative entropy metrics (Hartley, Quadratic, Tsallis, Rényi, and more) are popular in the social and the natural sciences, computer science, and philosophy of science. Particular entropy measures have been predominant in particular research areas, and it is often an open issue whether these divergences emerge from different theoretical and practical goals or are merely due to historical accident. Cutting across disciplinary boundaries, we show that several entropy and entropy reduction measures arise as special cases in a unified formalism, the Sharma–Mittal framework. Using mathematical results, computer simulations, and analyses of published behavioral data, we discuss four key questions: How do various entropy models relate to each other? What insights can be obtained by considering diverse entropy models within a unified framework? What is the psychological plausibility of different entropy models? What new questions and insights for research on human information acquisition follow? Our work provides several new pathways for theoretical and empirical research, reconciling apparently conflicting approaches and empirical findings within a comprehensive and unified information-theoretic formalism.

With the wide application of computers and digital technologies, online information searching is being integrated into students’ learning process. Improving students’ creative question generation through online information searching is an emerging research topic in the creativity and pedagogy field. Online information searching brings diversified information, but it also leads to cognitive load brought by a large amount of online information. Using online information searching to generate creative questions depends on students’ cognitive properties. However, the (...) existing literature ignores the joint influence of students’ online information searching strategies and cognitive properties on their creative question generation. This study puts forward three hypotheses: first, the two strategies of students’ online information searching will increase their creative question generation; second, the impact of “keywords” is negatively moderated by students’ need for cognitive closure ; third, the impact of “Web page exploration” is positively moderated by NFCC. The main reason is that high NFCC prevents students from obtaining diversified perspectives by using different keywords, but it helps to avoid distractions caused by a large amount of online information and promote the persistency of their reading information. Based on the data of quasi-experimental tasks completed by 90 students in Grade 7 and Grade 8, the results support the above hypothesis. The contributions of creative question generation theory and NFCC theory, as well as important issues of future study, are discussed. (shrink)

According to the ‘Description–Experience gap’, when people are provided with the descriptions of risky prospects they make choices as if they overweight the probability of rare events; but when making decisions from experience after exploring the prospects’ properties, they behave as if they underweight such probability. This study revisits this discrepancy while focusing on information-search in decisions from experience. We report findings from a lab-experiment with three treatments: a standard version of decisions from description and two versions of (...) decisions from experience: with and without a ‘history table’ recording previously sampled events. We find that people sample more from lotteries with rarer events. The history table proved influential; in its absence search is more responsive to cues such as a lottery’s variance while in its presence the cue that stands out is the table’s maximum capacity. Our analysis of risky choices captures a significant DE gap which is mitigated by the presence of the history table. We elicit probability weighting functions at the individual level and report that subjects overweight rare events in experience but less so than in description. Finally, we report a measure that allows us to compare the type of DE gap found in studies using choice patterns with that inferred through valuation and find that the phenomenon is similar but not identical across the two methods.

Individual differences in decisiveness: pre-decisional information search and decision strategy use We investigated whether individual differences in decisiveness are associated with a tendency to use different decision strategies during pre-decisional information search. To explore these potential links we administered the Need for Cognitive Closure questionnaire to 62 participants, followed by a probabilistic inference, multi-attribute choice task. Participants high in decisiveness dimension, compared to ‘low decisives’, spent less time and acquired less information prior to making decisions, (...) especially in the first trials of the choice task. ‘High decisives’ also had a greater tendency to use a simple Lexicographic heuristic than ‘low decisives’. The results support the view that high decisiveness is associated with greater tendency to simplify the decision process. (shrink)

Bank customers are not financial experts, and yet they make high-stakes decisions that can substantively affect personal wealth. Sooner or later, every individual has to take relevant investment decisions. Using data collected from financial advisors, bank customers and university students in Italy, this paper aims to reveal new insights about the decision processes of average non-expert investors: their investment goals, the information sets they consider, and the factors that ultimately influence decisions about investment products. Using four portfolio choice tasks (...) based on data collected directly from financial advisors and their clients, we find that most subjects used a limited set of information, ignoring factors that conventional economic models usually assume drive investor behavior. Furthermore, we suggest that non-compensatory decision-tree models, which make no trade-offs among investment features, are parsimonious descriptions of investor behavior useful for improving the organization of financial institutions and in policy contexts alike.

Bermúdez argues that framing effects are rational because particular frames provide goal-consistent reasons for choice and that people exert some control over the framing of a decision-problem. We propose instead that these observations raise the question of whether frame selection itself is a rational process and highlight how constraints in the choice environment severely limit the rational selection of frames.

This report reviews what quantum physics and information theory have to tell us about the age-old question, How come existence? No escape is evident from four conclusions: (1) The world cannot be a giant machine, ruled by any preestablished continuum physical law. (2) There is no such thing at the microscopic level as space or time or spacetime continuum. (3) The familiar probability function or functional, and wave equation or functional wave equation, of standard quantum theory provide mere continuum (...) idealizations and by reason of this circumstance conceal the information-theoretic source from which they derive. (4) No element in the description of physics shows itself as closer to primordial than the elementary quantum phenomenon, that is, the elementary device-intermediated act of posing a yes-no physical question and eliciting an answer or, in brief, the elementary act of observer-participancy. Otherwise stated, every physical quantity, every it, derives its ultimate significance from bits, binary yes-or-no indications, a conclusion which we epitomize in the phrase, it from bit. (shrink)

The fact that Internet companies may record our personal data and track our online behavior for commercial or political purpose has emphasized aspects related to online privacy. This has also led to the development of search engines that promise no tracking and privacy. Search engines also have a major role in spreading low-quality health information such as that of anti-vaccine websites. This study investigates the relationship between search engines’ approach to privacy and the scientific quality of (...) the information they return. We analyzed the first 30 webpages returned searching “vaccines autism” in English, Spanish, Italian, and French. The results show that not only “alternative” search engines but also other commercial engines often return more anti-vaccine pages (10–53%) than Google (0%). Some localized versions of Google, however, returned more anti-vaccine webpages (up to 10%) than Google. Health information returned by search engines has an impact on public health and, specifically, in the acceptance of vaccines. The issue of information quality when seeking information for making health-related decisions also impact the ethical aspect represented by the right to an informed consent. Our study suggests that designing a search engine that is privacy savvy and avoids issues with filter bubbles that can result from user-tracking is necessary but insufficient; instead, mechanisms should be developed to test search engines from the perspective of information quality (particularly for health-related webpages) before they can be deemed trustworthy providers of public health information.

The paper examines some of the processes of the closely knit relationship between Google’s ideologies of neutrality and objectivity and global market dominance. Neutrality construction comprises an important element sustaining the company’s economic position and is reflected in constant updates, estimates and changes to utility and relevance of search results. Providing a purely technical solution to these issues proves to be increasingly difficult without a human hand in steering algorithmic solutions. Search relevance fluctuates and shifts through continuous tinkering (...) and tweaking of the search algorithm. The company also uses third parties to hire human raters for performing quality assessments of algorithmic updates and adaptations in linguistically and culturally diverse global markets. The adaptation process contradicts the technical foundations of the company and calculations based on the initial Page Rank algorithm. Annual market reports, Google’s Search Quality Rating Guidelines, and reports from media specialising in search engine optimisation business are analysed. The Search Quality Rating Guidelines document provides a rare glimpse into the internal architecture of search algorithms and the notions of utility and relevance which are presented and structured as neutral and objective. Intertwined layers of ideology, hidden labour of human raters, advertising revenues, market dominance and control are discussed throughout the paper. (shrink)

John Maynard Smith has defended against philosophical criticism the view that developmental biology is the study of the expression of information encoded in the genes by natural selection. However, like other naturalistic concepts of information, this ‘teleosemantic’ information applies to many non-genetic factors in development. Maynard Smith also fails to show that developmental biology is concerned with teleosemantic information. Some other ways to support Maynard Smith’s conclusion are considered. It is argued that on any definition of (...) information the view that development is the expression of genetic information is misleading. Some reasons for the popularity of that view are suggested.

Wayfinding is generally understood as the process of purposefully navigating to distant and non-visible destinations. Within this broad framework, uninformed searching entails finding one’s way to a target destination, in an unfamiliar environment, with no knowledge of its location. Although a variety of search strategies have been previously reported, this research was largely conducted in the laboratory or virtual environments using simplistic and often non-realistic situations, raising questions about its ecological validity. In this study, we explored how extant findings (...) on searching translate to a real-world environment, using a phenomenologically informed experiment. Our findings demonstrate a previously undescribed complex and dynamic interplay of different search strategies. Importantly, our results reveal that: (i) the presence of other people is importantly entangled with the process of searching; and (ii) people frequently probe and switch between search strategies based on local environmental characteristics. Together, our results reveal that search behaviour is critically dependent on environmental features and that searching in complex real-world settings should not be conceptualised as depending on a simple singular strategy. This raises questions about the dominance of laboratory-based experiments and their narrow cognitivist framework, highlighting the value of studying wayfinding in the real world. (shrink)

In this study, we used a word search puzzle paradigm to investigate age differences in the rate of information gain and the cues used to make patch-departure decisions in information foraging. The likelihood of patch departure increased as the profitability of the patch decreased generally. Both younger and older adults persisted past the point of optimality as defined by the marginal value theorem, which assumes perfect knowledge of the foraging ecology. Nevertheless, there was evidence that adults were (...) rational in terms of being sensitive to the change in RG for making the patch-departure decisions. However, given the limitations in cognitive resources and knowledge about the ecology, the estimation of RG may not be accurate. Younger adults were more likely to leave the puzzle as the long-term RG incrementally decreased, whereas older adults were more likely to leave the puzzle as the local RG decreased. However, older adults with better executive control were more likely to adjust their likelihood of patch-departure decisions to the long-term change in RG. Thus, age-dependent reliance on the long-term or local change in RG to make patch-departure decisions might be due to individual differences in executive control. (shrink)

Issues of (...) both Science and Nature magazines celebrated the event by establishing interdisciplinary websites where readers can access essays on aspects of genome mapping and directly link to databases to search for more information on the topics (IV. Genome Gateway 2001; The Human Genome 2001). Since 1994, the National Information Resource on Ethics and Human Genetics (NIREHG), a special project of the National Reference Center for Bioethics Literature (NRC), has been providing such an integrated information service on ethics and genetics. Designed to enable a wide range of users to go from annotated bibliographies (Scope Notes) and brief essays (called "enotes") to database searching, NIREHG fosters an interdisciplinary approach to research on ethics and genetics. Links are provided between and among Scope Notes and enotes to information maintained on the NIREHG site as well as to sources found throughout the Internet. In providing the following annotations added to NIREHG materials since 1997, the Kennedy Institute of Ethics Journal (in its online presence through Project Muse) becomes an additional forum for NIREHG links.

For medical humanitarian organizations, making their sources of legitimacy explicit is a useful exercise, in response to: misperceptions, concerns over the ‘humanitarian space’, controversies about specific humanitarian actions, challenges about resources allocation and moral suffering among humanitarian workers. This is also a difficult exercise, where normative criteria such as international law or humanitarian principles are often misrepresented as primary sources of legitimacy. This essay first argues for a morally principled definition of humanitarian medicine, based on the selfless intention of individual (...) humanitarian actors. Taking Médecins Sans Frontières (MSF) as a case in point, a common source of moral legitimacy for medical humanitarian organizations is their cosmopolitan appeal to distributive justice and collective responsibility. More informally, their legitimacy is grounded in the rightfulness of specific actions and choices. This implies a constant commitment to publicity and accountability. Legitimacy is also generated by tangible support from the public to individual organizations, by commitments to professional integrity, and by academic alliances to support evidence-based practice and operational research.

New understanding of information and processes of physical (...)

In Search Of An Integrative Vision For Technology will stimulate its readers to consider the 'whole story that is information systems' within the context of an integrative vision of technology. It integrates disparate areas of debate and research while appreciating the contribution that philosophy can make to such thinking. It is deliberately broad in coverage, and designed to provide useful pointers so that researchers, students, practitioners, and developers can easily apply each point as needed. "Human issues of technology (...) and their normative aspects" is a theme that runs throughout the entire book. The integrative vision is centered on an understanding of human practice — the twin notions of structure and direction, and the leading and the founding functions of such practice. While this understanding applies to all technologies, it is worked out in more detail for information technology. From this philosophical understanding, many interdisciplinary areas of interest are identified. (shrink)

The ability of an agent to overcome limitations caused by complexity can be identified with intelligence. Yet, the study of complexity is dominated by the issues not really associated with authentic intelligence. In search of the methods to overcome limitations of complexity it is necessary to find a sufficiently general conceptual framework for its study, to identify its characteristics and sources, and then to explore alternatives to the currently used methods. The present paper is using for this purpose the (...) conceptual framework of information, its integration, and dynamics developed by the author in his earlier publications. Using this framework, complexity is characterized in both quantitative and qualitative ways, and in both static and dynamic perspectives. The main objective is to propose an approach to transcending limitations of complexity through reverse engineering of the effectiveness in overcoming complexity by natural, living organisms. Since the most striking characteristic of life is its hierarchic organization, the use of multi-level hierarchic information systems in information processing is explored. Theoretical design of such multi-level systems becomes possible with the use of generalized Turing machines as components performing concurrent computation on all levels of the hierarchy. (shrink)

Integrated information theory (IIT) is a candidate theory of consciousness that highlights the role of complex interactions between parts of a system as the basis of consciousness – and, due to its general information-theoretic formulation, is capable of making statements about consciousness in neural and non-neural systems alike. Here, we argue that a system radically different to a human brain, host to complex physiological and functional structures capable of integrating information, can be found in the meristems and (...) vascular system of higher plants. Following a pragmatic and ontologically innocent approach, neither taking for granted that plants are conscious nor dismissing the possibility that they are, we argue that the time is ripe to apply analysis tools inspired by IIT to plants, taking advantage of recent developments in both plant imaging and information theory. We introduce and discuss the relevant literature, and pro information and integration in plant behaviour, assessing the plausibility of plant sentience. If successful, these experiments could position plants as the next frontier in consciousness science, and urge us to rethink our perspectives on consciousness, how to measure it, and its prevalence amongst living beings.

Integrated information theory of consciousness proposes an identity between its causal structure and phenomenology. Through this assertion, IIT aims to explain consciousness by prioritizing first-person experience. However, despite its phenomenology-first stance, developments in IIT have overlooked temporality. As such, we argue that at present IIT’s phenomenological analysis is incomplete. In this critique, we show how IIT takes a non-identical illusionist stance towards the experiences of continuity, flow, and extent of our experiences. Moreover, in isolating temporal grains of experience to (...) a single timescale, IIT misses out on capturing the multi-scale nested nature of temporal phenomena. Hence, we contend that IIT needs an axiom for time, through which its causal structure can be refined to account for temporal experiences. Here, we propose an axiom to address these concerns. We conclude by discussing how IIT may need to be revised if our concerns hold true. (shrink)

She is no longer in the real world of her real home, she is in the virtual world of her virtual school.'_ Is this the shape of the future of education? This book presents a vision of what will happen to education and training as information technology develops. The argument is simple. To prepare people for life in an information society they need to be taught with the technology of an information society. But what shape will that take? Can the classroom as we know it - a communications system which has been in place for four thousand years - be replaced? The authors argue that through the development of telecommunications for telelearning a genuine revolution in education is in the making. The book describes how, through the convergence of a cluster of new technologies including virtual reality, artificial intelligence, nanotechnology and the superhighways of telecommunications, a new educational paradigm will emerge in the form of a virtual class. Teachers, trainers and educators who worry about how best to prepare students for life in an ever-changing world will find much inspiration in this engagingly written and jargon-free book. (shrink)

Many searches are needle-in-the-haystack problems, looking for small targets in large spaces. In such cases, blind search stands no hope of success. Success, instead, requires an assisted search. But whence the assistance required for a search to be successful? To pose the question this way suggests that successful searches do not emerge spontaneously but need themselves to be discovered via a search. The question then naturally arises whether such a higher-level “search for a search” (...) is any easier than the original search. We prove two results: (1) The Horizontal No Free Lunch Theorem, which shows that average relative performance of searches never exceeds unassisted or blind searches. (2) The Vertical No Free Lunch Theorem, which shows that the difficulty of searching for a successful search increases exponentially compared to the difficulty of the original search. (shrink)

Hypertext may represent a new paradigm capable of exploring legal sources within which links are established according to pertinent relationships found between statute texts and case law. However, to discover relevant information in such a network, a browsing mechanism is not enough when faced with a large volume of texts.

The purpose of this paper is to show how certain uses of search-engine technology raise concerns for personal privacy. In particular, we examine some privacy implications involving the use of search engines to acquire information about persons. We consider both a hypothetical scenario and an actual case in which one or more search engines are used to find information about an individual. In analyzing these two cases, we note that both illustrate an existing problem that (...) has been exacerbated by the use of search engines and the Internet – viz., the problem of articulating key distinctions involving the public vs. private aspects of personal information. We then draw a distinction between “public personal information” and “nonpublic personal information” to see how this scheme can be applied to a problem of protecting some forms of personal information that are now easily manipulated by computers and search engines – a concern that, following Helen Nissenbaum , we describe as the problem of privacy in public.

This paper is an overview of the idea that several aspects of human-like reasoning may be understood in a framework of information compression by 'multiple alignment', 'unification' and 'search'. These concepts will be described in outline together with a description of the SP61 computer model which is a partial realisation of the framework. A selection of examples are presented, illustrated with output from the SP61 model.

The study of information based on the approach of Shannon was detached from problems of meaning. Also, it did not allow analysis of the structural characteristics of information, nor describe the way structures carry information. An outline of a different theory of information, including its semantics, was earlier proposed by the author. This theory was using closure spaces to model information. In the present paper, structures (called syllogistics) underlying syllogistic reasoning as well as ethnoscientific classifications (...) are identified together with the conditions for the lattice of closed subsets describing information to allow its existence. The structures can be used for logical analysis outside of language at the more general level of information, which in turn can be applied to the description of semantic relations in the context of information.

We study from the proof complexity perspective the proof search problem : •Is there an optimal way to search for propositional proofs?We note that, as a consequence of Levin’s universal search, for any fixed proof system there exists a time-optimal proof search algorithm. Using classical proof complexity results about reflection principles we prove that a time-optimal proof search algorithm exists without restricting proof systems iff a p-optimal proof system exists.To characterize precisely the time proof (...) class='Hi'>search algorithms need for individual formulas we introduce a new proof complexity measure based on algorithmic information concepts. In particular, to a proof system P we attach information-efficiency function $i_P$ assigning to a tautology a natural number, and we show that: • $i_P$ characterizes time any P-proof search algorithm has to use on $\tau $,•for a fixed P there is such an information-optimal algorithm,•a proof system is information-efficiency optimal iff it is p-optimal,•for non-automatizable systems P there are formulas $\tau $ with short proofs but having large information measure $i_P$.We isolate and motivate the problem to establish unconditional super-logarithmic lower bounds for $i_P$ where no super-polynomial size lower bounds are known. We also point out connections of the new measure with some topics in proof complexity other than proof search. (shrink)

Humanity is moving towards a new world order, a “meta-civilization” with common values, processes, and organization, where cultural, national, and religious conflicts based on cultural differences are so easy to ignite and difficult to put out. In a world like this it is necessary to trace the origins of such differences, and study the conditions of their appearance. It is important to raise the awareness of the representatives of diverse civilizations and to encourage them to look for common grounds to (...) foster intercultural understanding. With regard to the newly emerging world, philosophers do not keep aloof, they do rise from their cozy armchairs and confront the factual world where it is most problematic. “Innovative” ideas put forward today by the experts of international relations who emphasize the role of different civilizations in the global world, in fact were generated by the Honolulu movement of comparative philosophy much earlier. The members of the movement were already aware of the vital need to bring together foreign, often conflicting, civilizations and search for common intellectual footage between them. As a response to the problem they proposed the idea of a “world philosophy.” The article presents a typology of six distinguishable meanings of a “world philosophy” that were developed and circulated by the Honolulu movement of comparative philosophy, with a brief critique of each meaning.

Dynamical activities within living eukaryotic cells are organized by microtubules, main structural components of the cytoskeleton and cylindrical polymers of the protein tubulin. Evidence and theoretical models suggest that states of tubulin may play the role of “bits” in classical microtubule computational automata. The advent of quantum information devices, key roles played by quantum processes in protein dynamics, and coherent ordering in the cell cytoplasm further suggest that microtubules may function as quantum computational devices, and that mesoscopic and macroscopic (...) quantum states are characteristic of living systems. In this paper new results from molecular dynamics simulation based on recently obtained atomic structure of tubulin are presented which provide support for classical and quantum modes of microtubule information processing.
