事后聪明式偏差的理论模型及影响因素

事后聪明式偏差是指人们在得知事件结果后,会因记忆扭曲、对自身预测能力或事件发生必然性的需要的诱发,而表现出过高估计自己在事前预测能力的现象。许多研究表明,该偏差普遍存在于实验和真实情境中,很难通过实施策略而减小。该现象的理论模型主要基于认知过程和社会性动机,影响因素有研究方法、个人特质、能力变量、年龄因素、个人相关度和事件效价,在未来研究中应注重对理论的整合以及校正策略在应用中的探索     

The typical student as an in‐group member: eliminating optimistic bias by reducing social distance

While demonstrations of optimistic bias are plentiful, successful attempts at eliminating the bias (debiasing) are rare. The current study attempted to debias by reducing the perceived social distance between the self and the typical own university student. Using self‐categorisation theory, it was predicted that rating the out‐group target (the typical student at another university) before the in‐group one would reduce the perceived social distance between the self and the latter and lead to a reduction in optimistic bias. Both predictions were supported, with optimistic bias being eliminated for negative events and attenuated for positive events. In the standard optimistic bias condition (in‐group first) optimistic bias was obtained for both negative and positive events. The findings provide support for perceived social distance in determining optimistic bias. The implications for recent arguments that comparisons with an abstract target automatically evoke an ‘I am better than average’ heuristic or necessarily entail the use of distributional judgmental frameworks are explored. Whilst the automatic linking of abstract targets with heuristic or distributional thinking is called into question, a case is made for integrating these ideas with the self‐categorisation approach. Where practitioners aim to reduce optimistic bias, the findings suggest promoting the perception of the target as a fellow in‐group member may help do so.

Measuring and Reducing Religious Bias in Post‐Conflict Zones: Evidence from Côte d'Ivoire

This article explores how religious bias, once it has been cultivated through politicization and violence, can be reduced. Using foundations from social identity theory and superordinate goal theory, I develop post‐conflict bias reduction strategies that include competing types of superordinate messages, economic and theological, as well as different sources of those messages. To test these strategies, I use video‐based information treatments coupled with Implicit Association Tests in Bouaké, Côte d'Ivoire. The experimental findings point to three conclusions. First, implicit Muslim‐Christian bias in the study area remains high. Second, Christians in the study tend to be more biased against Muslims than Muslims are against Christians. Third, the effectiveness of treatments depends on the subjects who receive those treatments: theological messages are most effective in reducing bias among Muslims, regardless of their source, and strategies that rely on political leaders to deliver messages perform best among Christians, regardless of the content.     

Metacognitive Experiences and Human Judgment: The Case of Hindsight Bias and Its Debiasing

ABSTRACT— Theories of judgment have emphasized the influence of what comes to mind—the content of people's thoughts. But recent research shows that metacognitive experiences accompanying thinking, like a sense of the ease or difficulty with which information comes to mind, qualify the conclusions that people derive from thought content. The case of hindsight bias and attempts to remove that bias (debiasing) illustrate this. After an event outcome is known, people display hindsight bias by exaggerating its inevitability, believing they "knew it all along." The magnitude of hindsight bias varies with the ease or difficulty that known or alternative outcomes come to mind; the usually observed hindsight bias may even reverse when outcomes are difficult to bring to mind or increase when alternatives are difficult to bring to mind. Implications of metacognitive experiences can extend to other biases and their debiasing, as well as to how people make sense of the past more generally.     

Giving Debiasing Away: Can Psychological Research on Correcting Cognitive Errors Promote Human Welfare?

ABSTRACT— Despite Miller's (1969) now-famous clarion call to "give psychology away" to the general public, scientific psychology has done relatively little to combat festering problems of ideological extremism and both inter- and intragroup conflict. After proposing that ideological extremism is a significant contributor to world conflict and that confirmation bias and several related biases are significant contributors to ideological extremism, we raise a crucial scientific question: Can debiasing the general public against such biases promote human welfare by tempering ideological extremism? We review the knowns and unknowns of debiasing techniques against confirmation bias, examine potential barriers to their real-world efficacy, and delineate future directions for research on debiasing. We argue that research on combating extreme confirmation bias should be among psychological science's most pressing priorities.     

But I thought I knew that: using confidence estimation as a debiasing technique to improve classroom performance

Our assessments of how much we know about a particular topic can be affected by our confidence in our knowledge. Research in judgement and decision making has shown that people are generally overconfident in their judgements or decisions, and that this bias can be reduced with training. We present two studies designed to assess whether debiasing can be accomplished in a classroom setting and whether it has practical value for students. In Experiment 1 simply providing confidence estimates as questions were answered was enough to debias students in a series of course‐related quizzes. In Experiment 2, weekly quizzes were given in a computer‐administered format. Students were given feedback for each question as it was completed. We found that accuracy on quizzes improved as confidence declined. We also found that students performed better in the course when they received debiasing training. We suggest that debiasing training prompted students to develop and use metacognitive skills that allowed them to assess their knowledge more accurately. Given this, training for these skills has practical value in the classroom. Copyright © 2001 John Wiley & Sons, Ltd.

Implicit bias and social schema: a transactive memory approach

To what extent should we focus on implicit bias in order to eradicate persistent social injustice? Structural prioritizers argue that we should focus less on individual minds than on unjust social structures, while equal prioritizers think that both are equally important. This article introduces the framework of transactive memory into the debate to defend the equal priority view. The transactive memory framework helps us see how structure can emerge from individual interactions as an irreducibly social product. If this is right, then debiasing interventions are structural interventions. One upshot is that the utility of the individual versus structural distinction is not apparent for the purposes of intervention.

     

Algebraic reasoning and bat-and-ball problem variants: Solving isomorphic algebra first facilitates problem solving later

The classic bat-and-ball problem is used widely to measure biased and correct reasoning in decision-making. University students overwhelmingly tend to provide the biased answer to this problem. To what extent might reasoners be led to modify their judgement, and, more specifically, is it possible to facilitate problem solution by prompting participants to consider the problem from an algebraic perspective? One hundred ninety-seven participants were recruited to investigate the effect of algebraic cueing as a debiasing strategy on variants of the bat-and-ball problem. Participants who were cued to consider the problem algebraically were significantly more likely to answer correctly relative to control participants. Most of this cueing effect was confined to a condition that required participants to solve isomorphic algebra equations corresponding to the structure of bat-and-ball question types. On a subsequent critical question with differing item and dollar amounts presented without a cue, participants were able to generalize the learned information to significantly reduce overall bias. Math anxiety was also found to be significantly related to bat-and-ball problem accuracy. These results suggest that, under specific conditions, algebraic reasoning is an effective debiasing strategy on bat-and-ball problem variants, and provide the first documented evidence for the influence of math anxiety on Cognitive Reflection Test performance.

Gender Bias in Medical Implant Design and Use: A Type of Moral Aggregation Problem?

In this article, I describe how gender bias can affect the design, testing, clinical trials, regulatory approval, and clinical use of implantable devices. I argue that bad outcomes experienced by women patients are a cumulative consequence of small biases and inattention at various points of the design, testing, and regulatory process. However, specific instances of inattention and bias can be difficult to identify, and risks are difficult to predict. This means that even if systematic gender bias in implant design is an ethical issue, it is one with no clearly blameworthy player. From a practical perspective, there is no single obvious point at which to intervene. Philosophers working in other areas have explored structurally similar moral problems—sometimes referred to as “moral aggregation problems”—such as the type of environmental harm caused by small actions of many players. I describe key features of these type of problems and strategies to address them. I then draw on these to suggest an approach to gender bias in medical implant design and use.     

Constructing an “HIV-Killer”: HIV Non-Disclosure and the Techniques of Vilification

Donileen Loseke has argued that social problems claims-making typically involves the construction of “people-categories” and more specifically the casting of victims and villains. While the processes by which victims are constructed have received attention in the literature, this is less so for villains. This article extends Loseke’s work by using the case of HIV non-disclosers to explore precisely how people are typified as villains. I analyze discourse—or “talk”—surrounding the criminalization of HIV non-disclosure and non-disclosers with a view to identifying some of the strategies used to vilify non-disclosers. I refer to these strategies as the techniques of vilification.     

Mending metacognitive illusions: a comparison of mnemonic-based and theory-based procedures

Previous research indicated that learners experience an illusion of competence during learning (termed foresight bias) because judgments of learning (JOLs) are made in the presence of information that will be absent at test. The authors examined the following 2 procedures for alleviating foresight bias: enhancing learners' sensitivity to mnemonic cues pertaining to ease of retrieval and inducing learners to resort to theory-based judgments as a basis for JOLs. Both procedures proved effective in mending metacognitive illusions-as reflected in JOLs and self-regulation of study time-but only theory-based debiasing yielded transfer to new items. The results support the notion that improved metacognition is 1 key to optimizing transfer but also that educating subjective experience does not guarantee generalization to new situations.     

The direct way may not be the best way: Children with ADHD and their understanding of self-presentation in social interactions

Knowledge and use of self-presentational tactics is an important social skill. We examined understanding of the function of three different self-presentational tactics (self-promotion, ingratiation and blasting) in 11 8–12-year-old boys with attention-deficit/hyperactivity disorder (ADHD) and 11 matched comparison children. Children were given six different self-presentation stories, two for each one of the three different tactics. After each story, they were asked to evaluate the effects of the self-presentational tactic used. Children with ADHD rated self-promotion and blasting as more positive and more effective—and ingratiation as less positive and less effective—than children in the control group. This implicates that children with ADHD prefer simple and direct self-presentational strategies (like self-promotion), and, therefore, may not as easily understand more subtle strategies (like ingratiation). They also seem to be more inclined to use negatively connoted strategies (like blasting). We suggest that this limited understanding of self-presentational strategies in children with ADHD may explain some of their problems in social interactions. Therefore, social skill interventions in children with ADHD should incorporate elements focusing on use and understanding of different self-presentational strategies.     

Subjective probability intervals: how to reduce overconfidence by interval evaluation

Format dependence implies that assessment of the same subjective probability distribution produces different conclusions about over- or underconfidence depending on the assessment format. In 2 experiments, the authors demonstrate that the overconfidence bias that occurs when participants produce intervals for an uncertain quantity is almost abolished when they evaluate the probability that the same intervals include the quantity. The authors successfully apply a method for adaptive adjustment of probability intervals as a debiasing tool and discuss a tentative explanation in terms of a naive sampling model. According to this view, people report their experiences accurately, but they are naive in that they treat both sample proportion and sample dispersion as unbiased estimators, yielding small bias in probability evaluation but strong bias in interval production.

Hyper-volume of eye-contact perception and social anxiety traits

Eye-contact facilitates effective interpersonal exchange during social interactions, but can be a considerable source of anxiety for individuals with social phobia. However, the relationship between the fundamental spatial range of eye-contact perception and psychiatric traits is, to date, unknown. In this study, I analyzed the eye-contact spatial response bias and the associated pupil response, and how they relate to traits of social interaction disorders. In a face-to-face situation, 21 pairs of subjects were randomly assigned to be either viewers or perceivers. The viewer was instructed to gaze either at the perceiver’s eyes, or at a predetermined point, and the perceiver was asked to indicate whether eye-contact had been established or not. I found that the perceptual volume is much larger than the actual volume of eye-contact, and that the subjective judgment of eye-contact elicited greater pupil dilation in the perceiver. Furthermore, the relationship between behavioral performance and social anxiety traits was identified. These findings provide new indications that internal traits related to lower social anxiety are potentially related to a restriction of spatial response bias for eye-contact.     

When is consensus knowledge based? Distinguishing shared knowledge from mere agreement

Scientific consensus is widely deferred to in public debates as a social indicator of the existence of knowledge. However, it is far from clear that such deference to consensus is always justified. The existence of agreement in a community of researchers is a contingent fact, and researchers may reach a consensus for all kinds of reasons, such as fighting a common foe or sharing a common bias. Scientific consensus, by itself, does not necessarily indicate the existence of shared knowledge among the members of the consensus community. I address the question of under what conditions it is likely that a consensus is in fact knowledge based. I argue that a consensus is likely to be knowledge based when knowledge is the best explanation of the consensus, and I identify three conditions—social calibration, apparent consilience of evidence, and social diversity, for knowledge being the best explanation of a consensus.     

差距知觉的泛化效应：我和你之间的差距有多大?

当知晓自己和他人的表现,即自己与他人在某方面表现上的差距已经明确时,人们对自我-他人差异的知觉准确吗?本研究发现了差距知觉的泛化效应：人们将自身的绝对表现(自己的表现与零相比的结果)泛化到对自身相对表现(自己与他人相比的结果)的判断上。在7个研究中, 被试(N = 2766)得知自己的绝对表现和相对于他人的表现,并判断自己与他人之间的差距。结果显示,绝对获益时,人们在相对获益时感知到的自我-他人差距大于相对损失时;绝对损失时,人们在相对获益时感知到的自我-他人差距小于相对损失时;当泛化难以进行时,上述效应消失。研究揭示了差距知觉的泛化效应及其联结机制。
