With the outset of automatic detection of information, misinformation, and disinformation, the purpose of this paper is to examine and discuss various conceptions of information, misinformation, and disinformation within philosophy of information.

The examinations are conducted within a Gricean framework in order to account for the communicative aspects of information, misinformation, and disinformation as well as the detection enterprise.

While there often is an exclusive focus on truth and falsity as that which distinguish information from misinformation and disinformation, this paper finds that the distinguishing features are actually intention/intentionality and non-misleadingness/misleadingness – with non-misleadingness/misleadingness as the primary feature. Further, the paper rehearses the argument in favor of a true variety of disinformation and extends this argument to include true misinformation.

The findings are novel and pose a challenge to the possibility of automatic detection of misinformation and disinformation. Especially the notions of true disinformation and true misinformation, as varieties of disinformation and misinformation, which force the true/false dichotomy for information vs mis-/disinformation to collapse.

An artificial chemistry approach is adopted to explore new ways of investigating a global dynamic of a collective belief. Five derivatives of belief are considered– knowledge, misbelief, delusion, ignorance, and doubt – to be reactants of an abstract chemical solution. The reactants interact one with another by certain laws obtained though unconventional interpretation of a belief update. Several types of reaction systems are studied in computational experiments with the doxastic solutions. A global dynamic of doxastic chemical solutions is also interpreted from a common‐sense point of view.

Consumer knowledge has been one of the most studied variables in marketing due to its strong influence on consumer behaviour. Knowledge level has traditionally been measured through objective knowledge and the number of correct answers in a battery of items about product characteristics. The authors argue that this analysis could be complemented with other information, that is, the structure of non-knowledge. The main objective of this work is to explore the nature and explanatory potential of this new dimension on consumer behaviour in the agrifood context. The principal hypothesis is that, while they may have similar levels of objective knowledge, there are significant differences between the behaviour of consumers who have a predominant pattern of ignorance (tendency to answer “I don't know”) and those who are in error (tendency to give wrong answers).

The present study draws on data derived from five case studies examining consumer knowledge about agrifood products (olive oils, Iberian ham and orange juice) and certain aspects of consumer behaviour. A sample of 4,112 participants was classified into two non-knowledge profiles: wrong, if most items answered incorrectly in a questionnaire were wrong; or ignorant, if most items answered incorrectly were “don't know”.

The results obtained supported the argument that complementing the study of consumer knowledge with an analysis of the structure of non-knowledge is worthwhile, as differences within the structure are associated with different patterns of consumer behaviour.

In the present study, it is proposed that the measurement of knowledge be complemented with an analysis of the consumer's non-knowledge structure (items not answered correctly), given its effects on behaviour, an aspect hitherto unconsidered in the literature. To do so, a new index is proposed.

In light of the relation between culture and markets, an analysis of cultural evolution reveals that globalization will not lead to the homogenization of world cultures.

The orthodox view about women in sport is that, when compared with males, females have always held, and will always continue to hold an inferior position in sporting achievement.

Misinformation is a significant phenomenon in today's world: the purpose of this paper is to explore the motivations behind the creation and use of misinformation.

A literature review was undertaken, covering the English and Russian language sources. Content analysis was used to identify the different kinds of motivation relating to the stages of creating and communicating misinformation. The authors applied Schutz's analysis of motivational types.

The main types of motivation for creating and facilitating misinformation were identified as “in-order-to motivations”, i.e. seeking to bring about some desired state, whereas the motivations for using and, to a significant extent, sharing misinformation were “because” motivations, i.e. rooted in the individual's personal history.

The general model of the motivations underlying misinformation is original as is the application of Schutz's typification of motivations to the different stages in the creation, dissemination and use of misinformation.

The purpose of this article is to examine the US history of advertising regulation, both formal and informal and public and private – particularly focused on advertising that is likely to mislead consumers about attributes, characteristics or performance of advertised products.

This research examines both primary sources such as legal challenges and contemporary writings as well as secondary sources.

Although early court decisions were reluctant to find advertising to be dishonest, the Post Office was the first government agency to challenge blatantly false advertisements through criminal prosecution. At the end of the 1800s, the nascent advertising industry developed an interest in regulating truthfulness to enhance advertising credibility. It proposed a model state criminal code and advertising clubs, followed by local Better Business Bureaus, began to informally resolve advertising dispute. In 1914, the Federal Trade Commission (FTC) was established with authority to prevent unfair methods of competition which it used to challenge advertising that was likely to injure competitors. This authority was later expanded to cover advertising that was likely to mislead consumers regardless of competitive injury. The FTC experimented with trade association advertising provisions and expanding its concepts and tools overtime until a period of retrenchment in the 1980s that set the foundations of modern advertising regulation.

This is the first treatment of advertising regulatory history that simultaneously covers and compares various sources of advertising regulation to develop a comprehensive exposition of advertising regulation history.

The purpose of this paper is to stress the role that several defective theories or views of the world played in generating the subprime financial crisis.

This is done by describing these views, showing that they were widely held by relevant decision makers, and by analyzing the flaws in these views. A considerable amount of literature is surveyed in the process.

It was found that these defective views did play a major role in generating the crisis.

Implications of the analysis for future research are discussed.

Implications of the analysis for reform of private and public sector financial policies are discussed.

While most of the arguments in the paper are not new, no paper of which the author is aware pulls them together with the same emphasis on how faulty mental models interacted with dangerous incentive structures to play a prime role in generating the crisis. The paper also references a much wider range of literature on the crisis than any study of which the author is aware. The paper should be of value to any one interested in the causes of the crisis and ways to make future crises less likely.

The purpose of this paper is to update and review the concept of warrant in Library and Information Science (LIS) and to introduce the concept of epistemic warrant from philosophy. Epistemic warrant can be used to assess the content of a work; and therefore, it can be a complement to existing warrants, such as literary warrant, in the development of controlled vocabularies. In this proposal, the authors aim to activate a theoretical discussion on warrant in order to revise and improve the validity of the concept of warrant from the user and classifier context to the classificationist context.

The authors have conducted an extensive literary review and close reading of the concept of warrant in LIS and knowledge organization in order to detect the different stances and gaps in which the concept of epistemic warrant might apply. The authors adopted an epistemological approach, in the vein of some of the previous commenters on warrant, such as Hope Olson and Birger Hjørland, and built upon the theoretical framework of different authors working with the concept of warrant outside knowledge organization, such as Alvin Plantinga and Alvin Goldman.

There are some authors and critics in the literature that have voiced for a more epistemological approach to warrant (in opposition to a predominantly ontological approach). In this sense, epistemic warrant would be an epistemological warrant and also a step forward toward pragmatism in a prominently empiricist context such as the justification of the inclusion of terms in a controlled vocabulary. Epistemic warrant can be used to complement literary warrant in the development of controlled vocabularies as well as in the classification of works.

This paper presents an exhaustive update and revision of the concept of warrant, analyzing, systematizing, and reviewing the different warrants discussed in the LIS literary warrant in a critical way. The concept of epistemic warrant for categorizational activities is introduced to the LIS field for the first time. This paper, and the proposal of epistemic warrant, has the potential to contribute to the theoretical and practical discussions on the development of controlled vocabularies and assessment of the content of works.

The purpose of this paper is to show how web sites can be a valuable research source for students if approached with due caution.

This article is the product of collaboration between a sociology professor and a librarian. The authors discuss the nature of their collaboration and present their views on web evaluation in the context of an extensive literature review.

Reputable print sources have numerous mechanisms to help ensure reliability: proven authors and editors, track record, and (sometimes) peer review. Obviously, the vast majority of web sites lack these features. Accordingly, the paper offers a critical look at the standard criteria of web evaluation with illustrations from two sites, one credible, one not.

Healthy skepticism regarding the internet is urged. It is suggested that web evaluation has costs and benefits. The chief benefit of careful web site evaluation is that the process makes it more likely than otherwise that one will wind up with reliable sites. The main cost is that evaluation takes time, and the value of a given piece of information declines according to the effort one spends verifying it. A second potential cost is that undue skepticism can prompt one to dismiss perfectly respectable sites.
