Organisms,machines, and societies: From the vertical structure of adaptability to the management of information

The adaptability of organisms and human societies depends on the synergistic orchestration of processing modes at many different levels of organization, each with unique informational characteristics. Digital information technology is a narrow transect of this spectrum. Adaptability theory provides a tool for analyzing the interactions between these fundamentally different modes of processing and for delineating the factors that can lead to either positive or negative consequences for human life.     

Structural and functional information—an evolutionary approach to pragmatic information

The paper starts with a critics of the potential information which is related to the statistical entropy. In order to include the syntactic and semantic aspects of information, we propose a distinction between structural and functional information, instead. Structural information represents the structural determination of a system state, it measures the content of information, as given by the material structure. Functional information, on the other hand, represents the operational closure of the system, it could be e.g. an algorithm which activates and interprets the existing structural information.

From an evolutionary point of view, pragmatic information is generated by an interplay of structural and functional information. This leads to a new insight into the concept of pragmatic information, which is not an invariant of evolution, but must be steadily re‐generated.

The active role of information in a self‐organization process is demonstrated in a model of artificial agents. It is shown by means of computer simulations that the feedback of already existing information on the generation of new information performs analogies to the creation of a collective memory.     

The paradox of evolution

In the second (and expanded) version of Origin of the Species, Darwin introduces the term “advanced progressive development” in an attempt to describe the development of the more complex species from the simpler ones. More than 100 years have passed since Darwin tried to qualify and conceptualize the directional question of evolution, and very little progress has been made regarding the subject. The appearance of the species, from the simple to the more complex, is today an empirical fact, one which is no longer dependent upon any theory, including that of Darwin. This work examines the subject of advanced development in evolution by attempting to answer a few basic questions: What parameters may be used to evaluate complexity? Can any rules or order be identified as to the development of the species? Is the mechanism of “natural selection” sufficient to explain the direction or ‘purpose’ of evolution? Can the human race be included within the “rules” of Darwin's evolutionary theory?

The purpose of this essay is to develop and represent a new conceptual framework. Through this, it will be possible to offer a principle answer to all four questions.     

Different forms of causation in dynamical systems: Determinism,pattern generation,and information

The standpoint that three fundamentally inequivalent classes of system behavior exist, which deserve separate tools for their characterization, is developed. These classes are: determinism, pattern generation, and information. A simple explanation for the origin of these classes is given. The three classes are shown to correspond to the different possible ways in which the properties of the components of a system unfold in the course of the system's processes. Determinism will be defined as a form of causation in which the properties causing the behavior are factually the same as the ones which for the observer specify the current conditions of the system. As a consequence, deterministic systems can be characterized by state equations that describe how the observable properties change. Pattern generation is characterized here as a form of causation in which the observable properties and the behavior‐generating properties correspond to each other as one to the many. Consequently, we experience in terms of the observable properties a branching behavior which is characterized by a pattern of selections at the branching points, a pattern that stands in close correspondence with the visually perceivable patterns and forms, generated by the system's dynamics. Information will be understood as a name for a process and an instance of causation where properties that cause behavior differ from those which we directly observe. The behavior of the system appears to be a consequence of the content of information hidden in the components. This information is, in turn, epistemologically equivalent to the very causal process in which it is unfolded.     

Information-Hierarchical Organization of Natural Systems I: The Information-Physical Principle

The mathematical notion of information characterizing system organization as such has been developed. The information-physical principle, which characterizes an information exchange in natural hierarchical systems and has been confirmed by its numerous applications, is laid down. It is shown to be based on the ancient “matter–measure–information” concept of physical world structure and talked about in the Hermes Trismegistus's will.     

Information-Hierarchical Organization of Natural Systems II: Futures of Man–Biosphere Interactions and Climate Control

The informational influence of both the vegetation and human society on climate dynamics in moderate and arid zones is revealed. The stability of the Eurasia climate during the last 2,000 years was determined by the specific structure of the Christianity-Judaism sociobiosystem. The study has also revealed the potential information-hierarchical organization of human society with a 71,874-year existence. This organization includes three world religions (Buddhism, Christianity, and Islam) as subsystems and provides both the global stability of climate processes and the conservation of evolutionary developed information-hierarchical organization of the biosphere.     

Lateralization of object-shape information in semantic processing

An experiment was conducted to examine whether perceptual information, specifically the shape of objects, is activated during semantic processing. Subjects judged whether a target word was related to a prime word. Prime-target pairs that were not associated, but whose referents had similar shapes (e.g. LADDER-RAILROAD) yielded longer "no" responses than unassociated prime-target pairs, suggesting that shape information had been activated. A visual-field manipulation showed that, in right-handed subjects, this effect was localized in the left hemisphere. This finding is consistent with behavioral, brain imaging, and lesion data, which suggest that object shape at the category level is represented in the left hemisphere.     

Heuristics as beliefs and as behaviors: the adaptiveness of the "hot hand"

and analyzed reasoning by asking: what are the reasoner's goals? This emphasizes the adaptiveness of behavior rather than whether a belief is normative. Belief in the "hot hand" in basketball suggests that players experiencing streaks should be given more shots, but this has been seen as a fallacy due to failure to find dependencies between players' shots. Based on their findings, I demonstrate by Markov modeling and simulation that streaks are valid allocation cues for deciding who to give shots to, because this behavior achieves the team goal of scoring more. Empirically I show that this adaptive heuristic is supported by the fallacious belief in dependency, more so as skill level increases. I extend the theoretical analysis to identify general conditions under which following streaks should be beneficial. Overall, this approach illustrates the advantages of analyzing reasoning in terms of adaptiveness.     

Applying evidence to support ethical decisions: Is the placebo really powerless?

Using placebos in day-to-day practice is an ethical problem. This paper summarises the available epidemiological evidence to support this difficult decision. Based on these data we propose to differentiate between placebo and “knowledge framing”. While the use of placebo should be confined to experimental settings in clinical trials, knowledge framing — which is only conceptually different from placebo — is a desired, expected and necessary component of any doctor-patient encounter. Examples from daily practice demonstrate both, the need to investigate the effects of knowledge framing and its impact on ethical, medical, economical and legal decisions. An earlier version of this paper was presented at an international conference, “Placebo: Its Action and Place in Health Research Today,” held in Warsaw, Poland on 12–13 April, 2003.
