Package leaflets belong to the complex communication system related to the minimization and prevention of pharmaceutical risk. Their legal nature is not exhausted by safety regulation though: as a privileged form of product instruction, they are also subject to liability regulation with a consequent reallocation of damage responsibility through risk disclosure. This article presents the results of a doctoral dissertation devoted to the legal and communicative analysis of PL information. After illustrating the articulation of pharmaceutical risk through risk prevention norms, the paper goes on with a discussion of the PL role within the therapeutic decision as a complementary vehicle to doctor’s information. It results that the liability framework in which both information channels are embedded determines a communication model, which far from promoting a shared decision process, radicalizes the two-step communication structure typical of the informed consent model inherited by surgery judicature. The second part investigates PL information as a source of knowledge updating through the methodological tools provided by Bayesian decision theory. Finally, an empirical study conducted over a sample of 55 drug consumers investigates the impact of PL information on drug risk perception and its perceived value to therapeutic decision.

Findings about the desire for health-risk information are heterogeneous and sometimes contradictory. In particular, they seem to be at variance with established psychological theories of information-seeking behavior.The present paper posits the decision about treating illness with medicine as the causal determinant for the expected net value of information, and attempts to explain idiosyncrasies in information-seeking behavior by using the notion of decision sensitivity to incoming information.Furthermore, active information avoidance is explained by modeling the expected emotional distress potentially brought about by “bad news” as a disutility factor in pay-off maximization.In this context two notions of uncertainty are distinguished: an epistemic uncertainty related to the prognostic probability assigned to the risk, and an emotional uncertainty related to the expected damage. Health-risk information can both reduce epistemic and increase emotional uncertainty, giving rise to idiosyncratic processing strategies.

Purpose The purpose of this paper is to suggest a definition of genetic information by taking into account the debate surrounding it. Particularly, the objections raised by Developmental Systems Theory to Teleosemantic endorsements of the notion of genetic information as well as deflationist approaches which suggest to ascribe the notion of genetic information a heuristic value at most, and to reduce it to that of causality. Design/methodology/approach The paper presents the notion of genetic information through its historical evolution and analyses it with the conceptual tools offered by philosophical theories of causation on one side and linguistics on the other. Findings The concept of genetic information is defined as a special kind of cause which causes something to be one way rather than another, by combining elementary units one way rather than another. Tested against the notion of “genetic error” this definition demonstrates to provide an exhaustive account of the common denominators associated with the notion of genetic information: causal specificity; combinatorial mechanism; arbitrariness. Originality/value The definition clarifies how the notion of information is understood when applied to genetic phenomena and also contributes to the debate on the notion of information, broadly meant, which is still affected by lack of consensus.
