How can anyone be rational in a world where knowledge is limited, time is pressing, and deep thought is often an unattainable luxury? Traditional models of unbounded rationality and optimization in cognitive science, economics, and animal behavior have tended to view decision-makers as possessing supernatural powers of reason, limitless knowledge, and endless time. But understanding decisions in the real world requires a more psychologically plausible notion of bounded rationality. In Simple heuristics that make us smart (Gigerenzer et al. 1999), we (...) explore fast and frugal heuristics – simple rules in the mind's adaptive toolbox for making decisions with realistic mental resources. These heuristics can enable both living organisms and artificial systems to make smart choices quickly and with a minimum of information by exploiting the way that information is structured in particular environments. In this précis, we show how simple building blocks that control information search, stop search, and make decisions can be put together to form classes of heuristics, including: ignorance-based and one-reason decision making for choice, elimination models for categorization, and satisficing heuristics for sequential search. These simple heuristics perform comparably to more complex algorithms, particularly when generalizing to new data – that is, simplicity leads to robustness. We present evidence regarding when people use simple heuristics and describe the challenges to be addressed by this research program. Key Words: adaptive toolbox; bounded rationality; decision making; elimination models; environment structure; heuristics; ignorance-based reasoning; limited information search; robustness; satisficing; simplicity.

Alfred Schutz’s theory of the social world, often neglected in philosophy, has the potential to capture the interplay of identity and difference which shapes our action, interaction, and experience in everyday life. Compared to still dominant identity-based models such as that of Jürgen Habermas, who assumes a coordination of meaning built on the idealisation of stable rules, Schutz’s theory is an important step forward. However, his central notion of a “type” runs into a difficulty which requires constructive criticism. Against the (...) background of Schutz’s theory of meaning inspired by Bergson and Husserl, his idea of types “taken for granted until further notice” is shown to express a primacy of identity which, in the final analysis, leads into the implausible scenario of ‘ubiquitous tunnel vision’. This makes it necessary to go beyond Schutz and assume an inherently motivated tendency towards difference in meaning termed ‘spontaneity’. Where spontaneity and the opposed tendency towards identity of meaning work together in the application of types, they enable embodied subjects to interact with the world and with each other in the routine yet flexible and sometimes innovative ways which we all know.

This paper addresses the notion of communicative action on the basis of Alfred Schutz’ writings. In Schutz’ work, communication is of particular significance and its importance is often neglected by phenomenologists. Communication plays a crucial role in his first major work, the Der sinnhafte Aufbau der sozialen Welt from 1932, yet communication is also a major feature in his unfinished works which were later completed posthumously by Thomas Luckmann: The Structures of the Life World (1973, 1989). In these texts, Schutz (...) sometimes refers to “communicative action,” and he comes to ascribe a crucial role to communication within the domain of the life world he calls everyday life. Based on Schutz’ texts, I shall first attempt to critically reconstruct the defining features of his notion of communication and communicative action. As a result, it emerges that Schutz’ notion of communication, particularly in its early incarnation, seems to be, at first glance, characterized by a dichotomy between virtual communication, that is communicative action in a narrow sense, and non-virtual communication. As I want to show with respect to the seemingly established dichotomous distinction between “mediated” and “immediate social action,” Schutz himself started to overcome this dichotomy. Based on this thesis, I will try to sketch a basic outline of a theory of communicative action, a theory less formulated by Schutz’ than built on Schutz’ writings. As the idea of communicative action, and particularly the transgression of the distinction between mediated and immediate action, affects the very structures of the life-world described by Schutz and Luckmann, I will ultimately demonstrate that any mundane phenomenology of the life-world requires a triangulatory method.

The growing presence of smart devices in our lives turns all of society into something largely unknown to us. The strategy of demanding transparency stems from the desire to reduce the ignorance to which this automated society seems to condemn us. An evaluation of this strategy first requires that we distinguish the different types of non-transparency. Once we reveal the limits of the transparency needed to confront these devices, the article examines the alternative strategy of explainable artificial intelligence and concludes (...) with the idea that these types of complex realities exceed individual capacities and are only comprehensible in a collective fashion.

This paper aims to explore the relations between Schutzian theory and hermeneutics. After presenting the connections between hermeneutic thought and Schutz’s work from a historical point of view, it will argue that despite its significant differences from hermeneutic theory, Schutzian theory can be utilized as a kind of proto-hermeneutics. By now, the heterogeneous movement of the interpretive social sciences has reached an established position, but with their growing reliance on the impulses coming from philosophical hermeneutics, the latent problem comes to (...) the foreground: the former demand for an action-theoretical grounding has faded away. Currently, action theory itself is no more dominated by the work of interpretively minded authors, but by the theories of rational choice. This results in a false opposition between the explanatory models, which base their arguments on historical, cultural, and linguistic factors, and those, which focus on the plane of the decisions of individuals. Bypassing the objectivism present in both the rational choice approach and hermeneutics, Schutz’s pragmatic theory of the life-world, originating from both interpretive and pragmatic intellectual influences, may be useful to overcome this opposition, and can serve as a proto-hermeneutical point of departure: that is, as a theory which cannot alone take over the duty of hermeneutics, but which can complement hermeneutics on a fundamental level.

This paper identifies experiential processes through which social structures become taken for granted, termed processes of “structure marginalization”. Passive processes of structure marginalization relegate social structures to the margin of experience without the use of higher-order cognitive acts such as evaluation and reflection. Examples include adapting to social structures via routine and habitual practices, a lack of conscious awareness of the complexity, historical formation, and other details of social structures, and rendering social structures irrelevant when they are unreflectively judged to (...) be of no value for achieving ends. Active processes of structure marginalization reflectively and discursively relegate social structures to marginal consciousness. Examples include the use of naturalistic and necessitarian explanations for the social order that implicitly justify it as inalterable or “just the way things are”, normative justifications for the status quo, and conscious awareness of one’s powerlessness to control social-structural conditions. Active processes of structure marginalization originate in passive processes. The goal of the typology is to explain, at the level of experience, why social structures typically remain unproblematic and unnoticed in everyday life, even during periods of social crisis and change or when existing structures produce harmful effects.

This paper presents the concept of the idealization of the interchangeability of phases of life as an enhancement, or rather as a further development of Alfred Schutz’s general thesis of the reciprocity of perspectives. It claims that the according figure of thought is a constitutive part of acts of understanding in everyday life where, in order to understand each other, individuals of different age-groups have to overcome the difference of perspectives that are attached to their particular ages. This is accomplished (...) by a specific assumption that is also applied in the case of intrasubjective, autobiographical understanding. By discussing its sociological significance as well as its philosophical background, this paper introduces the idealization of the interchangeability of phases of life as a fundamental and universal figure of understanding.
