In this paper, I will discuss the responsibilities that scientists have for ensuring their work is interpreted correctly.
I will argue that there are three good reasons for scientists to work to ensure the appropriate communication of their findings.
First, I will argue that scientists have a general obligation to ensure scientific research is communicated properly based
on the vulnerability of others to the misrepresentation of their work. Second, I will argue that scientists have a special
obligation to do so because of the power we as a society invest in them as specialists and professionals. Finally, I will
argue that scientists ought to ensure their work is interpreted correctly based on prudential, self-interested considerations.
I will conclude by offering suggestions regarding policy considerations. 相似文献

Survey and behavioral measurements of interpersonal trust 总被引:1,自引:0,他引:1
Although many studies treat trust as a situational construct, individual differences can be used to study and predict trusting behavior. We report two studies, the first showing the psychometric properties of a new trust inventory (the Propensity to Trust Survey or PTS), the second study validating this inventory using the standard economic task, the Investment Game. The first study utilized online survey data (N > 8000) to show that the PTS scales were reliable and measured broad constructs related to Big Five personality domains. Trust was related to extraversion and negative neuroticism, and trustworthiness was related to agreeableness and conscientiousness. The second study (N = 90) validated the PTS trust scale as a predictor of behavior in the Investment Game. These findings are evidence that trust and trustworthiness are compound personality traits, and that PTS scales are preferable to general Big Five measures for predicting trusting behavior. 相似文献

Faced with extreme demands, hypothetical thinking runs the danger of total failure. Paradoxical propositions such as the Liar (“I am lying”) provide an opportunity to test it to its limits, while the Liar's nonparadoxical counterpart, the Truthteller (“I am telling the truth”), provides a useful comparison. Two experiments are reported, one with abstract materials (“If I am a knave then I live in Emerald City”) and one with belief-laden materials (a judge says: “If I am a knave then I enjoy pop music”). In both experiments, conditionals with Truthteller-type antecedents were “collapsed” to responses of conditional probability closely resembling estimates of control items. Liar-type antecedents, in contrast, dramatically weakened belief in conditionals in which they were embedded. The results are discussed in the framework of the theory of hypothetical thinking. 相似文献

In this study, we focus on the conditions which permit people to assert a conditional statement of the form 'if p then q' with conversational relevance. In a broadly decision-theoretic approach, also drawing on hypothetical thinking theory [Evans, J. St. B. T. (2007). Hypothetical thinking: Dual processes in reasoning and judgement. Hove, UK: Psychology Press.], we predicted that conditional tips and promises would appear more useful and persuasive and be more likely to encourage an action p when (a) the conditional link from p to q was stronger, (b) the cost of the action p was lower and (c) the benefit of the consequence q was higher. Similarly, we predicted that conditional warnings and threats would be seen as more useful and persuasive and more likely to discourage an action p when (a) the conditional link from p to q was stronger, (b) the benefit of the action p was lower and (c) the cost of the consequence q was higher. All predictions were strongly confirmed, suggesting that such conditionals may best be asserted when they are of high relevance to the goals of the listener. 相似文献

Laboratory analogues of classroom activities on which children with low working memory skills have been observed to perform very poorly were developed and employed in two studies. In Study 1, 5‐ and 6‐year‐old completed one task involving recalling spoken sentences and counting the numbers of words, and another task involving the identification of rhyming words in spoken poems. Poorer performance of low than average working memory children was obtained on the recall measure of both tasks. In Study 2, 5‐ and 6‐year‐old children heard spoken instructions involving the manipulation of a sequence of objects, and were asked either to perform the instructions or repeat them, in different conditions. The accuracy of performing but not repeating instructions was strongly associated with working memory skills. These results indicate that working memory plays a significant role in typical classroom activities that involve both the storage and mental manipulation of information.

The purpose of this study was to examine the impact of cumulative risk exposure in concert with maternal responsiveness on physiological indicators of chronic stress in children and youth. Middle-school children exposed to greater accumulated psychosocial (e.g., family turmoil, poverty) and physical (e.g., crowding, substandard housing) risk factors manifested higher levels of allostatic load, a physiological marker of cumulative wear and tear on the body caused by the mobilization of multiple, physiological response systems. This effect was longitudinal, residualizing allostatic load 3-4 years earlier when the youth were in elementary school. This effect, however, occurred only among adolescents with mothers low in responsiveness. Cumulative risk was also associated with dynamic cardiovascular processes in response to an acute stressor (mental arithmetic). Higher risk was associated with muted reactivity and slower, less efficient recovery in blood pressure. These dynamic cardiovascular effects occurred irrespective of maternal responsiveness. 相似文献

Conditionals in natural language are central to reasoning and decision making. A theoretical proposal called the Ramsey test implies the conditional probability hypothesis: that the subjective probability of a natural language conditional, P(if p then q), is the conditional subjective probability, P(q/p). We report three experiments on causal indicative conditionals and related counterfactuals that support this hypothesis. We measured the probabilities people assigned to truth table cases, P(pq), P(p notq), P( notpq) and P( notp notq). From these ratings, we computed three independent predictors, P(p), P(q/p) and P(q/ notp), that we then entered into a regression equation with judged P(if p then q) as the dependent variable. In line with the conditional probability hypothesis, P(q/p) was by far the strongest predictor in our experiments. This result is inconsistent with the claim that causal conditionals are the material conditionals of elementary logic. Instead, it supports the Ramsey test hypothesis, implying that common processes underlie the use of conditionals in reasoning and judgments of conditional probability in decision making. 相似文献

Recent assessments have shown that capuchin monkeys, like chimpanzees and other Old World primate species, are sensitive to
quantitative differences between sets of visible stimuli. In the present study, we examined capuchins’ performance in a more
sophisticated quantity judgment task that required the ability to form representations of food quantities while viewing the
quantities only one piece at a time. In three experiments, we presented monkeys with the choice between two sets of discrete
homogeneous food items and allowed the monkeys to consume the set of their choice. In Experiments 1 and 2, monkeys compared
an entirely visible food set to a second set, presented item-by-item into an opaque container. All monkeys exhibited high
accuracy in choosing the larger set, even when the entirely visible set was presented last, preventing the use of one-to-one
item correspondence to compare quantities. In Experiment 3, monkeys compared two sets that were each presented item-by-item
into opaque containers, but at different rates to control for temporal cues. Some monkeys performed well in this experiment,
though others exhibited near-chance performance, suggesting that this species’ ability to form representations of food quantities
may be limited compared to previously tested species such as chimpanzees. Overall, these findings support the analog magnitude
model of quantity representation as an explanation for capuchin monkeys’ quantification of sequentially presented food items.
