Purpose With the increasing sophistication of neuroimaging technologies in medicine, new language is being sought to make sense of the findings. The aim of this paper is to explore whether the brain-reading metaphor used to convey current medical or neurobiological findings imports unintended significations that do not necessarily reflect the genuine findings made by physicians and neuroscientists. Methods First, the paper surveys the ambiguities of the readability metaphor, drawing from the history of science and medicine, paying special attention to the (...) sixteenth through nineteenth centuries. Next, the paper addresses more closely the issue of how metaphors may be confusing when used in medicine in general, and neuroscience in particular. The paper then explores the possible misleading effects associated with the contemporary use of the brain-reading metaphor in neuroimaging research. Results Rather than breaking new ground, what we see in current scientific language is a persistence of both a constraining and expansive set of language practices forming a relatively continuous tradition linking current neuroimaging to past scientific investigations into the brain. Conclusions The use of the readability metaphor thus carries with it both positive and negative effects. Physicians and neuroscientists must resort to the use of terms already laden with abstracted meanings, and often burdened by tradition, at the risk of importing through these words connotations that do not tally with the sought-after objectivity of empirical science.

In this paper, I argue that companies who use functional Magnetic Resonance Imaging (fMRI) scans for lie detection encounter the same basic ethical stumbling blocks as commercial companies that market traditional polygraphs. Markets in traditional voluntary polygraphs are common and fail to elicit much uproar among ethicists. Thus, for consistency, if markets in polygraphs are ethically unproblematic, markets using fMRIs for lie detection are equally as acceptable. Furthermore, while I acknowledge two substantial differences between the ethical concerns involving polygraphs and (...) fMRI lie detection, I argue that these concerns can be overcome and do not lead to the conclusion that markets in fMRI lie detection are ethically dubious. It is my conclusion that voluntary markets in fMRI lie detection can be justified by consumer autonomy and should be allowed to persist. (shrink)

Detection of deception and confirmation of truth telling with conventional polygraphy raised a host of technical and ethical issues. Recently, newer methods of recording electromagnetic signals from the brain show promise in permitting the detection of deception or truth telling. Some are even being promoted as more accurate than conventional polygraphy. While the new technologies raise issues of personal privacy, acceptable forensic application, and other social issues, the focus of this paper is the technical limitations of the developing technology. Those (...) limitations include the measurement validity of the new technologies, which remains largely unknown. Another set of questions pertains to the psychological paradigms used to model or constrain the target behavior. Finally, there is little standardization in the field, and the vulnerability of the techniques to countermeasures is unknown. Premature application of these technologies outside of research settings should be resisted, and the social conversation about the appropriate parameters of its civil, forensic, and security use should begin.

Some classic historical vignettes depict scientists achieving breakthroughs without effort: Archimedes grasping the principles of buoyancy while bathing, Galileo Galilei discovering the isochrony of the pendulum while sitting in a cathedral, James Watt noticing the motive power of steam while passing time in a kitchen, Alexander Fleming finding penicillin in Petri dishes that he had omitted to clean before going on holiday. These stories suggest that, to establish important findings in science, hard work is not always necessary. In this article, (...) I suggest that such stories capture an important aspect of scientific.. (shrink)

Character-trait attribution is an important component of everyday social cognition that has until recently received insufficient attention in traditional accounts of folk psychology. In this paper, I consider how the case of character-trait attribution fits into the debate between mindreading-based and broadly ‘pluralistic’ approaches to folk psychology. Contrary to the arguments of some pluralists, I argue that the evidence on trait understanding does not show that it is a distinct, non-mentalistic mode of folk-psychological reasoning, but rather suggests that traits are (...) ordinarily understood as mentalistic dispositions. I also examine several ways in which trait attribution might also serve regulative, ‘mindshaping’ functions by promoting predictable norm-governed behavior, and argue that mindreading plays several important roles in these cases as well. I conclude that an appreciation of the relationship between trait attribution and mindreading is crucial to understanding the role it plays in our folk psychology. (shrink)

Functional magnetic resonance imaging and the electroencephalography -based technology of Brain Fingerprinting have been hailed as the next, best technologies for lie detection in America, particularly in the context of post-9/11 anxiety. In scientific journals and the popular press, each has been juxtaposed and deemed superior to traditional polygraphy, which measures changes in the autonomic nervous system and correlates these fluctuations with emotions such as anxiety, fear, and guilt. The author contends that the juxtaposition of polygraphy and brain-based detection is (...) a rhetorical strategy that foregrounds the corrective advantage of brain-based techniques, creates an artificial rupture between contiguous technologies, and ignores the shared assumptions foundational to fMRI, EEG, and two older ``truth telling'' technologies: polygraphy and fingerprinting. Far from describing the brain and its functions, fMRI and Brain Fingerprinting produce models of the brain that reinforce social notions of deception, truth, and deviance. (shrink)
