Forensic science error rates are needlessly high. Applying the perspective of veritistic social epistemology to forensic science could produce new institutional designs that would lower forensic error rates. We make such an application through experiments in the laboratory with human subjects. Redundancy is the key to error prevention, discovery, and elimination. In the “monopoly epistemics” characterizing forensics today, one privileged actor is asked to identify the truth. In “democratic epistemics,” several independent parties are asked. In an experiment contrasting them, democratic (...) epistemics reduced the rate at which biased observers obscured the truth by two-thirds. These results highlight, first, the potential of “epistemic systems design,” which employs the techniques of economic systems design to address issues of veracity rather than efficiency, and second, the value of “experimental epistemology,” which employs experimental techniques in the study of science.

Epistemic systems are social processes generating judgments of truth and falsity. I outline a mathematical theory of epistemic systems that applies widely. Areas of application include pure science, torture, police forensics, espionage, auditing, clinical medical testing, democratic procedure, and the market economy. I examine torture and police forensics in relative detail. This paper is an exercise in comparative institutional epistemics, which considers how the institutions of an epistemic system influence its performance as measured by such things as error rates and (...) the volume of judgments generated.

The American criminal justice system creates incentives for false conviction. For example, many public crime labs are funded in part per conviction. We show that the number of false convictions per year in the American criminal justice system should be considered ?high.? We examine the incentives of police, forensic scientists, prosecutors, and public defenders in the U.S. Police, prosecutors, and forensic scientists often have an incentive to garner convictions with little incentive to convict the right person. These incentives create what (...) economists call a ?multitask problem? that seems to be resulting in a needlessly high rate of false convictions. Public defenders lack the resources and incentives needed to provide a vigorous defense for their clients. Corrective measures are discussed, along with a call for more research. (shrink)

L’activité entrepreneuriale génère l’activité entrepreneuriale. Cet article développe cette idée dans une perspective autrichienne. Nous envisageons les entrepreneurs kirznériens sous l’angle de l’apprentissage hayékien. L’activité entrepreneuriale développe l’activité entrepreneuriale de deux manières. Premièrement, la mise en oeuvre d’une nouvelle tentative crée de nouvelles opportunités pour d’autres nouvelles tentatives. Deuxièmement, chaque acte entrepreneurial kirznérien est un exemple incitant les autres à faire de même. Nous mettons l’accent sur le second point. Chaque nouvelle tentative entrepreneuriale modifie les perceptions des autres quant à (...) l’émergence des opportunités, aux gens qui peuvent les saisir, etc. Elle rend les gens plus vigilants. Ainsi, l’action entrepreneuriale crée des externalités positives. Ces externalités expliquent que des communautés, par ailleurs identiques, donnent lieu à des niveaux différents de tentatives entrepreneuriales.Entrepreneurship breeds entrepreneurship. This insight is developed within the context of Austrian economics. We view Kirznerian entrepreneurs as Hayekian learners. Entrepreneurship breeds entrepreneurship two ways. First, the founding of a new venture creates new opportunities for other new ventures. Second, each act of Kirznerian entrepreneurship is a favorable example for others to follow. We concentrate on the second point. Each act of newventure entrepreneurship changes the perceptions of others about how new ventures are founded, what sort of person might do it, and so on. It makes people more alert. Thus, entrepreneurship creates a network externality. This externality explains the fact that otherwise similar communities produce dissimilar levels of new-venture entrepreneurship. (shrink)

Israel Kirzner’s concept of “alertness” is recast in the language of phenomenological psychology. Our ideas about things are either openended ideas posing no particular problem of choice, “open possibilities”, or alternatives to choose between, “problematic possibilities”. Choice is the process of formulating problematic possibilities; it is the process of reinterpreting one’s situation. The fully formed reinterpretation generates the chosen outcome as a necessary consequence of preferences and perceived constraints. Reinterpretation precedes choice, both logically and temporally. This understanding of alertness helps (...) to clarify Austrian ideas such as the idea that preferences do not exist apart from action.Le concept de “vigilance” d’Israel Kirzner est reformulé dans le langage de la psychologie phéno- ménologique. Nos idées à propos des choses sont souvent des idées à finalité ouverte ne soulevant pas de problème particulier de choix, “des possibilités ouvertes”, ou des alternatives de choix entre des “possibilités problématiques”. Le choix est un processus de formulation de possibilités problématiques ; c’est le processus consistant à réinterpréter nos propres situations. Dans sa formulation ultime, la réinterprétation génère le résultat choisi comme conséquence nécessaire des préférences et des contraintes perçues. La réinterprétation précède le choix, et logiquement et temporellement. Cette compréhension de la vigilance aide à clarifier les idées Autrichiennes telle que l’idée selon laquelle les préférences n’existent pas indépendamment de l’action. (shrink)

The discovery of traces of a blood meal in the abdomen of a 50‐million‐year‐old mosquito reminds us of the insights that the chemistry of fossils can provide. Ancient DNA is the best known fossil molecule. It is less well known that new fossil targets and a growing database of ancient gene sequences are paralleled by discoveries on other classes of organic molecules. New analytical tools, such as the synchrotron, reveal traces of the original composition of arthropod cuticles that are more (...) than 400 my old. Pigments such as melanin are readily fossilized, surviving virtually unaltered for ∼200 my. Other biomarkers provide evidence of microbial processes in ancient sediments, and have been used to reveal the presence of demosponges, for example, more than 635 mya, long before their spicules appear in the fossil record. Ancient biomolecules are a powerful complement to fossil remains in revealing the history of life. (shrink)

A growing literature testifies to the persistence of place as an incorrigible aspect of human experience, identity, and morality. Place is a common ground for thought and action, a community of experienced particulars that avoids solipsism and universalism. It draws us into the philosophy of the ordinary, into familiarity as a form of knowledge, into the wisdom of proximity. Each of these essays offers a philosophy of place, and reminds us that such philosophies ultimately decide how we make, use, and (...) understand places, whether as accidents, instruments, or fields of care.

In order to introduce protists to philosophers, we outline the diversity, classification, and evolutionary importance of these eukaryotic microorganisms. We argue that an evolutionary understanding of protists is crucial for understanding eukaryotes in general. More specifically, evolutionary protistology shows how the emphasis on understanding evolutionary phenomena through a phylogeny-based comparative approach constrains and underpins any more abstract account of why certain organismal features evolved in the early history of eukaryotes. We focus on three crucial episodes of this history: the origins (...) of multicellularity, the origin of sex, and the origin of the eukaryote cell. Despite ongoing uncertainty about where the root of the eukaryote tree lies, and residual questions about the precise endosymbioses that have produced a diversity of photosynthesizing eukaryotes, evolutionary protistology has illuminated with considerable clarity many aspects of protist evolution. Our main message in light of evolutionary protistology is that these ‘other eukaryotes’ are in fact the organisms through which the rest of the eukaryotes should be understood. (shrink)

Cette dernière diffère du tout au tout de l’individualisme qui fonde l’approche occidentale dont la terminologie est éloquente (agents, actions, traits de caractères, autonomie, choix, liberté, principes…). L’éthique confucéenne s’appuie d’abord sur une vision totalisante de l’expérience humaine et recourt à un ensemble de termes qui révèlent des idées totalement différentes : par exemple que les qualités morales se manifestent sous la forme d’une virtuosité consommée dans les rôles et les relations qui nous constituent.

It is widely believed that a person's traits can function as reasons for loving her. Notable contemporary work in the philosophy of love has taken the rejection of this premise as its point of departure. As far as I can tell, none of that work has engaged with a careful philosophical exposition of the view under discussion. In the following pages, I will defend the idea of trait-based love against three of its critics and one of its advocates. I will (...) discuss work on this topic by Harry Frankfurt, Niko Kolodny and David Velleman, arguing that their criticisms fail and that the alternatives they offer to trait-based love create more difficulties than they solve. What these authors have in common is a deflationary approach to love that reduces it to a beneficent disposition, a valuing relationship and a visceral form of moral regard, respectively. I will compare these to the multiplex, nuanced depiction of trait-based love in Plato's Symposium. While it is plausible that love can motivate a beneficent disposition, develop in relationships and entails moral regard, I will argue that the attempt to reduce it to any of the foregoing fails. Frankfurt, Kolodny and Velleman reject trait-based love in part because they think it would differ in unacceptable ways from the love most of us practice. Plato advocates the cultivation of a love that in some respects resembles the picture of trait-based love the contemporary authors balk at. However, unlike those critics, he appreciates that trait-based love need not resemble the ideal he proposes. His richer view of love accounts for elements such as need and feeling that the contemporary thinkers are driven to implausibly bracket as distractions. As I will try to show, the most compelling criticisms of Platonic love do not tell against its responsiveness to the loved one's traits. I will argue that trait-based love is consistent with an intuitive picture of love and that this commonsense approach is more defensible than competing views in these texts. These authors' disagreements about what can count as reasons for love are bound up with the differences in what each takes love to be. Thus, in the course of arguing for trait-based love, I will critically assess their various proposals as to the nature of love. (shrink)

This book recalls, for nonscientific readers, the history of quantum mechanics, the main points of its interpretation, and Einstein's objections to it, together with the responses engendered by his arguments. We point out that most popular discussions on the strange aspects of quantum mechanics ignore the fundamental fact that Einstein was correct in his insistence that the theory does not directly describe reality. While that fact does not remove these counterintuitive features, it casts them in a different light."--page vi.

The derivation of the expression for the density matrix of scattered particles in terms of that of the incident ones, taking different impact parameters into account, shows that under well-specified and realistic conditions, the final density matrix is of the same kind as the initial one. Thus the final mixed state after a collision can be used directly as the initial mixed state in a subsequent collision. Contrary to a recent claim by Band and Park, there are no “fundamental difficulties (...) with quantum mechanical collision theory.”. (shrink)

My theme in this essay is the relation of misfortune – and other occasions for regret – to the affirmation of life. R. Jay Wallace believes there is an antagonistic relation that produces a schism between our affirmative attitudes and our reasons and considered judgments. On his view, our attachments to the persons and projects that give meaning to our lives lead us to affirm states of affairs it would be more appropriate to regret. I argue that the attitude of (...) affirmation can acknowledge and do justice to reasons for regret. Wallace fails to appreciate the implications of the Nietzschean positions he cites as precedents; he assumes the past has a meaning that is fixed and insulated from the future. Drawing on Nietzsche, I argue that the affirmation of life is a coherent project of bestowing meaning on a historical sequence going forward into the future. (shrink)
