The Normativity of Experience and Causal Belief in Hume’s Treatise

What is the source of normativity in Hume’s account of causal reasoning? In virtue of what are causal beliefs justified for Hume? To answer these questions, the literature appeals, almost invariably, to custom or some feature thereof. I argue, in contrast, that causal beliefs are justified for Hume because they issue from experience. Although he denies experience the title of justifying reason, for Hume experience has normative authority. I offer an interpretation of the source and nature of the normativity of experience in causal reasoning. I argue that the senses and memory have a special, positive status within the mind in virtue of their force and vivacity, which, on my reading, Hume identifies with a sense of presentness and a strong effect on the mind. Hume dignifies the system of memory and the senses with the title of reality because of these features. Causal beliefs are dignified as “realities” because they issue from reality. However, because the imagination can sometimes enhance the force and vivacity of ideas without the help of experience, Hume appeals to coherence and general rules as well.

The gap between parents’ knowledge and causal beliefs about etiology of autism: A key variable to understand parents’ anxiety

Autism Spectrum Disorders (ASD) are associated with higher levels of anxiety for parents [1]. Provide medical information about autism etiology is the first step to help parents to understand the child disorder and to cope with it. The medical current community accepts that autism is a neurodevelopmental disorder in which genes play a role but that environmental factors likely contribute as well [2]. This conception can meet parent's beliefs constructed on their cultural values and personal experiences. In line with causal attribution theory [3], it is important to consider to parental beliefs because it can impact the treatment choices and the child developmental trajectory [4]. The Main purpose is to evaluate the consistency between parental knowledge and beliefs about ASD etiology. The second purpose is to explore the impact of consistency on parents’ anxiety. We interviewed through open-ended questions 89 parents of ASD children aged between 3 to 10 years about their knowledge and their beliefs about ASD etiology. A content analysis was performed using the Nvivo10 software. Anxiety is evaluated with the subscale of the Hospital Anxiety and Depression Scale (HADS). In agreement with previous work four categories of causes have been identified: biological (BIO), psychological (PSY), multifactorial etiology (BIO + PSY), others (OT). A percentage of 55.1% of parents is consistent between their knowledge and beliefs about ASD etiology while 43.8% are inconsistent. Parent anxiety is significantly higher (T (71.91) = 2.34; P < 0.05) when knowledge and beliefs are inconsistent than when they are consistent. This study demonstrates the deleterious impact of inconsistency between knowledge and beliefs about ASD etiology, on parental anxiety. In order to provide relevant support for parents, information delivered after diagnosis must consider pre-existing parental beliefs. A systematic assessment of parental beliefs would adjust the information provided after the diagnosis.

Hong Kong Chinese women's lay beliefs about cervical cancer causation and prevention.

This study aimed to seek insights into Chinese women's lay beliefs about cervical cancer causal attributions and prevention. Twenty-three new immigrant adult women from Mainland China and thirty-five Hong Kong adult women underwent semi-structured in-depth interviews. Interviews were audio taped, transcribed and analyzed using a Grounded Theory approach. This study generated three foci: causal beliefs about cervical cancer, perceived risk of cervical cancer, and beliefs about cervical cancer prevention. Personal risky practices, contaminated food and environment pollution were perceived as the primary causes of cervical cancer. New immigrant women more likely attributed cervical cancer to external factors. Most participants perceived cervical cancer as an important common fatal female cancer with increased risk/prevalence. Many participants, particularly new immigrant women participants, expressed helplessness about cervical cancer prevention due to lack of knowledge of prevention, it being perceived as beyond individual control. Many new immigrant participants had never undergone regular cervical screening while almost all Hong Kong participants had done so. Some Chinese women hold pessimistic beliefs about cervical cancer prevention with inadequate knowledge about risk factors. Future cervical cancer prevention programs should provide more information and include capacity building to increase Chinese women's knowledge and self-efficacy towards cervical cancer prevention.

Inherited or Behavior? What Causal Beliefs about Obesity Are Associated with Weight Perceptions and Decisions to Lose Weight in a US Sample?

Objectives. To identify the extent to which (1) beliefs about obesity and obesity-related behaviors distinguish individuals based on weight perception (WP) and (2) beliefs about obesity predict perceived health status and WP and how these in turn predict decisions to try to lose weight. Method. 7456 noninstitutionalized US adults (Mage = 54.13, SDage = 16.93; 61.2% female; 75.9% White) completed the 2007 Health Information National Trends Survey. Multinomial logistic regressions and structural equation modeling were used to accomplish study objectives. Results. Age, gender, information-seeking, health status, belief that obesity is inherited, and knowledge of fruits and vegetables recommendations distinguished participants based on WP. Beliefs about obesity predicted health status, WP, and trying to lose weight in the general model. The models varied based on gender, race/ethnicity, education, and weight misperception. Conclusion. This study supports the role of beliefs about obesity, WP, and health perceptions in individuals' decisions and actions regarding weight management. This study increases our understanding of gender, race/ethnicity, education, and weight misperceptions differences in decisions to lose weight. This knowledge may lead to targeted interventions, rather than “one size fits all” interventions, to promote health and prevent obesity.

Uma teoria naturalista da justificação das crenças na epistemologia de David Hume

One of the first difficulties in interpreting Hume’s epistemological writings concerns precisely the meaning of the words ‘knowledge’ and ‘belief’. In this article it is shown, initially, how, from a humean point of view, the traditional epistemic criterion to define ‘knowledge’ and ‘belief’ appears very restrictive. Hume’s theory of causal belief is then briefly reviewed in the light of epistemological naturalism of the Michael J. Costa and Louis E. Loeb. Finally, it is submitted that the examination of all these topics lends support to the Hume’s naturalistic theory of justification of beliefs.

Beliefs and perceptions about the causes of breast cancer: a case-control study.

BackgroundAttributions of causality are common for many diseases, including breast cancer. The risk of developing breast cancer can be reduced by modifications to lifestyle and behaviours to minimise exposure to specific risk factors, such as obesity. However, these modifications will only occur if women believe that certain behaviours/lifestyle factors have an impact on the development of breast cancer.MethodThe Breast Cancer, Environment and Employment Study is a case-control study of breast cancer conducted in Western Australia between 2009 and 2011. As part of the study 1109 women with breast cancer and 1633 women without the disease completed a Risk Perception Questionnaire in which they were asked in an open-ended question for specific cause/s to the development of breast cancer in themselves or in others. The study identified specific causal beliefs, and assessed differences in the beliefs between women with and without breast cancer.ResultsThe most common attributions in women without breast cancer were to familial or inherited factors (77.6%), followed by lifestyle factors, such as poor diet and smoking (47.1%), and environmental factors, such as food additives (45.4%). The most common attributions in women with breast cancer were to mental or emotional factors (46.3%), especially stress, followed by lifestyle factors (38.6%) and physiological factors (37.5%), particularly relating to hormonal history.ConclusionsWhile the majority of participants in this study provided one or more causal attributions for breast cancer, many of the reported risk factors do not correspond to those generally accepted by the scientific community. These misperceptions could be having a significant impact on the success of prevention and early detection programs that seek to minimise the pain and suffering caused by this disease. In particular, women who have no family history of the disease may not work to minimise their exposure to the modifiable risk factors.

An analysis of laypeople’s beliefs regarding the origins of their worst nightmare

While many studies have examined the aetiological underpinnings and psychological correlates of nightmares, very few have focused on laypeople’s conceptions of the underlying causes of their own nightmares. The present study investigated laypeople’s causal beliefs about their worst nightmare experience and examined whether these beliefs varied as a function of participants’ gender, age of nightmare occurrence, and recurrence of the nightmare itself. Five hundred and eighty-three adult participants completed a series of questionnaires and their beliefs categorized according to a coding protocol. The results showed that: 1) The three most frequently reported explanations for people’s worst nightmare were difficult interpersonal relationships, attributions of unknown or nonexistent causality, and mediums of entertainment; 2) Women were more likely than men to attribute their worst nightmare to factors related to interpersonal relationships; 3) Some attributions varied depending on whether the worst nightmare had occurred during childhood, adolescence, or adulthood; and 4) Worst nightmares that were recurrent in nature were more likely to be attributed to phobias and negative emotions than non-recurrent worst nightmares. Interestingly, many of the lay beliefs endorsed in the present study were in line with empirical and theoretical studies on the aetiology of nightmares.

Biogenetic explanations and emotional reactions to people with schizophrenia and major depressive disorder

Using population-based data, the relationship between biogenetic causal beliefs and emotional reactions to persons with schizophrenia or depression was examined. Biogenetic attributions elicited either negative emotions alone or pro-social and negative emotions at the same time. Biogenetic attributions seem not helpful for improving emotional reactions to people with mental disorders.

The Australian public׳s beliefs about the causes of schizophrenia: Associated factors and change over 16 years

This study investigated the Australian public׳s beliefs about the causes of schizophrenia and whether these beliefs have changed over a 16-year period. Data came from the 2011 Australian National Survey of Mental Health Literacy and Stigma which involved telephone interviews with 1995 Australians aged 15 or over. The survey interview used the same questions as those of the 2003/4 and 1995 national mental health literacy surveys, in which participants were presented with a case vignette describing either early or chronic schizophrenia. Questions were asked about recognition of, exposure to and causal beliefs about these disorders, including those relating to psychosocial, biogenetic and personality factors. Results showed that most Australians believe in multifactorial causes of schizophrenia and that, between 1995 and 2011, belief in problems from childhood and inherited or genetic causes of early schizophrenia increased while belief in weakness of character decreased. Overall, the findings are consistent with evidence that mental health literacy in Australia has improved over a 16-year period.

Breast Cancer Cause Beliefs: Chinese, Korean, and Mexican American Breast Cancer Survivors.

This study examined causal attribution beliefs about breast cancer and the influence that these beliefs exert on health behavior change among breast cancer survivors (BCS). Focus groups with Chinese (n = 21), Korean (n = 11), and Mexican American (n = 9) BCS recruited through community- and hospital-based support groups were conducted. Interviews were audio-recorded, transcribed verbatim, and translated into English for thematic content analysis. Three themes concerning beliefs about breast cancer cause common to all three groups included (a) stress, (b) diet, and (c) fatalism. Causal beliefs corresponded to behavioral changes with women describing efforts to improve their diet and manage their stress. Ethnic minority BCS adhere to beliefs about what caused their cancer that influence their health behaviors. Providing quality health care to ethnically diverse cancer survivors requires cultural sensitivity to patients' beliefs about the causes of their cancer and awareness of how beliefs influence patients' health behaviors post diagnosis.

Beliefs of people taking antidepressants about causes of depression and reasons for increased prescribing rates

BackgroundPublic beliefs about the causes of mental health problems are related to desire for distance and pessimism about recovery, and are therefore frequently studied. The beliefs of people receiving treatment are researched less often. MethodAn online survey on causal beliefs about depression and experiences with antidepressants was completed by 1829 New Zealand adults prescribed anti-depressants in the preceding five years, 97.4% of whom proceeded to take antidepressants. ResultsThe most frequently endorsed of 17 causal beliefs were family stress, relationship problems, loss of loved one, financial problems, isolation, and abuse or neglect in childhood. Factor analysis produced three factors: ‘bio-genetic’, ‘adulthood stress’ and ‘childhood adversity’. The most strongly endorsed explanations for increases in antidepressant prescribing invoked improved identification, reduced stigma and drug company marketing. The least strongly endorsed was ‘Anti-depressants are the best treatment’. Regression analyses revealed that self-reported efficacy of the antidepressants was positively associated with bio-genetic causal beliefs, negatively associated with childhood adversity beliefs and unrelated to adulthood stress beliefs. The belief that ‘People cannot׳ get better by themselves even if they try’ was positively associated with bio-genetic beliefs. LimitationsThe convenience sample may have been biased towards a favourable view of bio-genetic explanations, since 83% reported that the medication reduced their depression. ConclusionsClinicians׳ should consider exploring patients׳ causal beliefs. The public, even when taking antidepressants, continues to hold a multi-factorial causal model of depression with a primary emphasis on psycho-social causes. A three factor model of those beliefs may lead to more sophisticated understandings of relationships with stigma variables.

Different biogenetic causal explanations and attitudes towards persons with major depression, schizophrenia and alcohol dependence: Is the concept of a chemical imbalance beneficial?

ObjectiveIt is unclear whether different biogenetic causal beliefs affect stigmatization of mentally-ill patients differently. It has been argued that in particular believing in a ‘chemical imbalance’ as a cause of mental disorder might be associated with more tolerant attitudes. MethodIn a representative population survey in Germany (n=3642), using unlabelled case vignettes of persons with depression, schizophrenia, or alcohol dependence, we elicited agreement with three different biogenetic explanations of the illness: ‘Chemical imbalance of the brain’, ‘brain disease’ and ‘heredity’. We further investigated emotional reactions as well as the desire for social distance. For each vignette condition we calculated linear regressions with each biogenetic explanation as independent and emotional reactions as well as social distance as dependent variable controlling for socio-demographic variables. LimitationsOur cross-sectional study does not allow statements regarding causality and the explanatory power of our statistical models was low. Results‘Chemical imbalance of the brain’ and ‘brain disease’ were both associated with a stronger desire for social distance in schizophrenia and depression, and with more social acceptance in alcohol dependence, whereas ‘heredity’ was not significantly associated with social distance in any of the investigated illnesses. All three biogenetic causal beliefs were associated with more fear in all three illnesses. ConclusionOur study corroborates findings that biogenetic explanations have different effects in different disorders, and seem to be harmful in depression and schizophrenia. A particular de-stigmatizing potential of the causal belief ‘chemical imbalance’ could not be found. Implications for useful anti-stigma messages are discussed.

Mechanisms of informal governance: evidence from the IEA

How does informal governance occur in international organisations? While the existing literature suggests that power asymmetries matter a great deal for explaining the uncodified rules and procedures that often develop within international organisations, we argue that power asymmetries alone cannot explain informal governance. Consequently, we develop two specific mechanisms through which informal governance occurs. First, we suggest that regime complexity can act as a source of incentives and opportunities for informal governance. In the face of regime complexity, informal governance offers an attractive way of keeping states bound to the organisation and of managing complex interactions with adjacent regimes. Second, we propose that the coincidence of frozen formal structures and changing causal beliefs allows informal governance to emerge. Problems of great causal complexity are sometimes subject to swings in beliefs about cause–effect relationships, demanding new policy approaches. When such swings occur, and if it is costly to adapt an organisation’s formal rules, states and institutions often simply create unwritten, informal practices as a way to render the institution dynamic. The plausibility of our conjectures is illustrated with evidence drawn from the International Energy Agency.

Risk perception is not associated with attendance at a preventive intervention for type 2 diabetes mellitus among South Asians at risk of diabetes.

To evaluate the association between risk perception and attendance in a diabetes prevention programme among South Asians with a high risk for diabetes. An observational study. We measured risk perception during the baseline interview with causal beliefs, perceived susceptibility and perceived controllability. We used logistic regression to examine the relationship between risk perception and attendance. We adjusted for relevant sociodemographic factors, screening results and psychosocial factors. The Hague, the Netherlands. Five hundred and thirty-five Hindustani Surinamese (South Asians) aged 18-60 years from a lifestyle-versus-control intervention for the prevention of diabetes. In total, 68·2% attended the lifestyle or control intervention. Participants perceived lifestyle and heredity to increase the risk of diabetes and perceived increasing physical activity to decrease it. Only 44·2% of the participants perceived themselves as susceptible to diabetes and only those who perceived a family history of diabetes as a cause of diabetes appeared to be more inclined to attend. However, after adjustment for confounding, the association was not statistically significant. Risk perception was not significantly associated with attendance. The results suggest that increasing the risk perception alone in this South Asian population is unlikely to increase the attendance at a diabetes prevention programme.

The development and initial validation of a questionnaire to measure help-seeking behaviour in patients with new onset rheumatoid arthritis.

Early treatment for rheumatoid arthritis (RA) is vital. However, people often delay in seeking help at symptom onset. An assessment of the reasons behind patient delay is necessary to develop interventions to promote rapid consultation. Using a mixed methods design, we aimed to develop and test a questionnaire to assess the barriers to help seeking at RA onset. Questionnaire items were extracted from previous qualitative studies. Fifteen people with a lived experience of arthritis participated in focus groups to enhance the questionnaire's face validity. The questionnaire was also reviewed by groups of multidisciplinary health-care professionals. A test-retest survey of 41 patients with newly presenting RA or unclassified arthritis assessed the questionnaire items' intraclass correlations. During focus groups, participants rephrased questions, added questions and deleted items not relevant to the questionnaire's aims. Participants organized items into themes: early symptom experience, initial reactions to symptoms, self-management behaviours, causal beliefs, involvement of significant others, pre-diagnosis knowledge about RA, direct barriers to seeking help and relationship with GP. The test-retest survey identified seven items (out of 79) with low intraclass correlations which were removed from the final questionnaire. The involvement of people with a lived experience of arthritis and multidisciplinary health-care professionals in the preliminary validation of the DELAY (delays in evaluating arthritis early) questionnaire has enriched its development. Preliminary assessment established its reliability. The DELAY questionnaire provides a tool for researchers to evaluate individual, cultural and health service barriers to help-seeking behaviour at RA onset.

Multifactorial beliefs about the role of genetics and behavior in common health conditions: prevalence and associations with participant characteristics and engagement in health behaviors.

PurposeMany common health conditions arise due to a combination of genetic factors and lifestyle-related behaviors. People’s understanding of the multifactorial nature of health conditions has implications for their receptivity to health messages regarding genomics and medicine, and may be related to their adoption of protective health behaviors. Although past work has investigated aspects of either genetic or behavioral causal beliefs, multifactorial beliefs have not been evaluated systematically.MethodsUtilizing nationally-representative cross-sectional data from the Health Information National Trends Survey (HINTS), we examined the prevalence of multifactorial beliefs regarding the etiology of cancer, obesity, diabetes, heart disease, and hypertension, as well as associations between such beliefs and demographic, health history, and health behavior variables in the U.S. population.ResultsAmong 3,630 participants, the vast majority (64.2-78.6%) endorsed multifactorial beliefs. The number of statistically significant associations were limited. Trends suggest that endorsement of multifactorial beliefs may differ by demographic and health history characteristics. Beliefs about the multifactorial etiology of cancer were associated with cancer screening behaviors. Multifactorial beliefs about other common health conditions were associated with few health promotion behaviors.ConclusionThese findings and recommendations for future research provide preliminary guidance for developing and targeting genomics-related health messages and communications.

Medical and nursing students' attitudes to people with mental illness in Nigeria: a tale of two teaching hospitals

This study compared beliefs about and attitudes to mental illness among medical and nursing students at two teaching hospitals in Nigeria with very different levels of psychiatric instructional capacity. Factor analysis of responses to a 43-item self-report questionnaire identified three domains: social acceptance of people with mental illness; belief in non-superstitious causation of mental illness; and stress, trauma and poverty as external causes of mental illness, with entitlement to employment rights. Students at the hospital with a larger, functioning psychiatry department had significantly higher scores on all three factors. Culturally enshrined beliefs and attitudes about mental illness are not uncommon among medical trainees. The availability of psychiatric education and services may have a positive effect on beliefs and attitudes.

Using consumer perspectives to inform the cultural adaptation of psychological treatments for depression: A mixed methods study from South Asia

BackgroundIntegrating consumer perspectives in developing and adapting psychological treatments (PTs) can enhance their acceptability in diverse cultural contexts. ObjectiveTo describe the explanatory models (EMs) of depression in South Asia with the goal of informing the content of culturally appropriate PTs for this region. MethodsTwo methods were used: a systematic review of published literature on the EMs of depression in South Asia; and in-depth interviews with persons with depression and family caregivers in two sites in India. Findings from both were analysed independently and then triangulated. ResultsThere were 19 studies meeting our inclusion criteria. Interviews were conducted with 27 patients and 10 caregivers. Findings were grouped under four broad categories: illness descriptions, perceived impact, causal beliefs and self-help forms of coping. Depression was characterised predominantly by somatic complaints, stress, low mood, and negative and ruminative thoughts. Patients experienced disturbances in interpersonal relationships occupational functioning, and stigma. Negative life events, particularly relationship difficulties, were perceived as the main cause. Patients mostly engaged in distracting activities, religious practices, and received support from family and friends to cope with the illness. LimitationsThe primary data are entirely from India but the studies from the literature review covering South Asia are consistent with these findings. This study also does not include literature in local languages or explore how consumer perspectives change over time. ConclusionsEMs can inform cultural adaptations to PTs for depression in South Asia by defining target outcomes, content for psycho-education, and culturally appropriate treatment strategies.
