Giving the Benefit of the Doubt

Abstract

Faced with evidence that what a person said is false, we can nevertheless trust them and so believe what they say – choosing to give them the benefit of the doubt. This is particularly notable when the person is a friend, or someone we are close to. Towards such persons, we demonstrate a remarkable epistemic partiality. We can trust, and so believe, our friends even when the balance of the evidence suggests that what they tell us is false. And insofar as belief is possible, it is also possible to acquire testimonial knowledge on those occasions when the friends know what they tell us. This paper seeks to explain these psychological and epistemological possibilities.     

Trust in the Normative Domain

Abstract

Pessimists about trust in the normative domain believe that (i) forming normative beliefs on the basis of trusting others is problematic, (ii) forming normative beliefs in other ways is not so problematic and (iii) forming non-normative beliefs on the basis of trust is not so problematic. Whilst there is substantial disagreement over the best way of accounting for pessimist ideas about trust, it is widely accepted that the intuitively problematic character of forming normative beliefs on the basis of trust cannot be explained in terms of the idea that trust cannot be a source of normative knowledge. This paper argues that the dismissal of scepticism about trust as a source of normative knowledge is unwarranted. It does so by developing a sceptical explanation of pessimist ideas, arguing that the obvious arguments against the sceptical explanation fail and arguing that the sceptical explanation has the resources to resolve the considerations that present problems for existing explanations.     

The Social Value of Non-Deferential Belief

We often prefer non-deferential belief to deferential belief. In the last twenty years, epistemology has seen a surge of sympathetic interest in testimony as a source of knowledge. We are urged to abandon ‘epistemic individualism’ and the ideal of the ‘autonomous knower’ in favour of ‘social epistemology’. In this connection, you might think that a preference for non-deferential belief is a manifestation of vicious individualism, egotism, or egoism. I shall call this the selfishness challenge to preferring non-deferential belief. The aim of this paper is to meet the selfishness challenge by arguing that non-deferential belief is (pro tanto) socially valuable.     

心理学关于目击证人证言可靠性实证研究

目击证人的证词在刑事诉讼中有着极为重要的作用,但是由于证人对案件的记忆往往会受到其自身和外界各种因素的干扰,因此,对于目击证人证词可靠性的研究引起了心理学界的关注,西方心理学界自上个世纪七十年代以来,从证人的年龄性别、心理状态、对证人的询问方式以及辨认的情景等方面进行了大量的实证研究,为司法实践提供了重要的启示。本文从以上四个方面全面总结了西方心理学界关于证人证词可靠性的实证研究,并作了分析与展望。     

Introduction to a Special Issue of the Journal of Investigative Psychology and Offender Profiling

When offender profiles have been presented as evidence in court, although in a few cases they may have been accepted initially, they have invariably been excluded on appeal. But with the evolution of Investigative Psychology as a systematic science with a broader remit than producing ‘offender profiles’, a framework for contributions to investigations has emerged over the last 20 years that maps out the rich potential range of contribution to the legal process. This considers not only the drawing of inferences about offenders from their actions (profiling), but also examination of testimony and what psychological processes may indicate whether it has been distorted deliberately or accidentally. Further, the decision-making processes, especially as part of the investigation that gave rise to evidence presented are also subject to behavioural scrutiny. This special issue of The Journal of Investigative Psychology and Offender Profiling provides examples of these contributions as a basis for encouraging debate about links between Investigative Psychology and the courtroom.

Secret-Keeping Behaviors in Black and White Children as a Function of Interviewer Race,Racial Identity,and Risk for Abuse

Summary

The tendency for children to keep the secret of child abuse is an important practical impediment to adequate research, prevention, assessment, and treatment. While some studies have established that children will readily keep adult secrets, few have investigated the predictors of ease of disclosure. In this research, race of the interviewer requesting the secret strongly affected disclosure, with Black children particularly showing an unwillingness to disclose a negative secret to a different race interviewer. Children at high risk for sexual abuse (as assessed by the Finkelhor checklist) also were more likely to keep the secret.     

Musicians processing music: Measurement of brain potentials with EEG

Abstract

In the present study, the EEG was recorded from the scalp of musicians while mentally active in their field. Analytic, creative and memory processes of the brain were observable using a special electrophysiological method called DC-potential recording. Music students listened to a sequence of four notes and subsequently were either to reverse the sequence (task 1 = analytic) or to compose a new continuation (task 2 = creative). In task 3, the initial segment of a well-known melody was presented and had to be continued (memory task). All tasks had to be solved mentally (imagery). In tasks 1 and 2, either tonal or atonal sequences were presented.

While processing, the results show that the analytic task elicited the highest brain activity. The analytic task involved mainly parieto-temporal areas of both hemispheres, the left hemisphere showing a tendency for domination. The memory task produced predominant activity over the right hemisphere. The creative task caused the lowest brain activation and elicited an unexpected lateralisation to the left, though we expected creativity to be a right hemispheric holistic-synthetic phenomenon.

Comparing listening with processing of the perceived music, we found a significant shift from an insignificant right hemispheric to an insignificant left hemispheric predominance (except with the memory task). This indicates that musicians do not lateralise to the left hemisphere per se when listening to music. Whether one finds a left hemispheric lateralisation in listening tasks or a right hemispheric one probably depends on the amount of simultaneous analytic-sequential processing the musician undertakes.     

Confidence and accuracy of lineup selections and rejections: Postdicting rejection accuracy with confidence

Correlation and calibration approaches show meaningful, positive confidence-accuracy relations for witnesses making selections from lineups, but rarely for rejections (Brewer and Wells, 2006, Sauerland and Sporer, 2009). This disparity may reflect the difference between selecting a single photo versus rejecting a set of photos. Participants (N = 101) in two experiments made selections from and rejections of lineups in situations requiring either a single confidence rating about a single face (typical of “choosers”) or a single confidence rating about multiple faces (typical of “nonchoosers”). Mean confidence ratings were significantly higher for accurate versus inaccurate decisions for both selections and rejections when decisions were based on single faces. Single decisions about multiple faces produced no significant difference in confidence between correct and incorrect rejections but a significant difference for selections.
