In his influential work on critical argumentation, Douglas Walton explains how to judge whether an argumentum ad verecundiam is fallacious or legitimate. He provides six critical questions and a number of ancillary sub-questions to guide the identification of reasonable appeals to authority. While it is common for informal logicians to acknowledge the role of bias in sampling procedures and hypothesis confirmation , there is a conspicuous lack of discourse on the effect of identity prejudice on judgments of authority, even though (...) this is a well-documented factor in attributing credibility, expertise, trustworthiness, and professional competence to oppressed groups. This could result in faulty judgments of ad verecundiam fallacy. Focusing on gender bias, I review recent works in feminist epistemology—particularly those of Miranda Fricker and Helen Longino —to develop three gender-based critical questions to supplement Walton’s original list of six. This addition will help us to identify erroneous dismissals of appeals to authority based on epistemic injustice and epistemic irresponsibility on the part of the speaker or knowledge community. This project promotes the overlapping aims of feminist epistemology and informal logic. (shrink)

ObjectiveTo examine body image perception and the associations of body dissatisfaction with socio-demographic and lifestyle factors among Saudi women attending fitness centers in Riyadh.MethodsSaudi females aged 16 years and older were recruited from 12 randomly selected fitness centers in Riyadh, using stratified clustered sampling technique. Height and weight were measured to calculate actual body mass index. A previously validated instrument was used to collect socio-demographic and lifestyle variables including physical activity, sedentary behaviors, sleep and dietary habits. Stunkard Figure Rating Scale (...) silhouettes were used to assess perceived and desired body shape.ResultsThe participants had a mean age of 29.2. The majority were not married, with no children and had college degrees. While 63% were overweight or obese, nearly 40% of women underestimated their perceived body shape. The majority of respondents were dissatisfied with their body shape including 68% of normal weight women. Females who had BD were significantly older, had higher BMI, reported more weight loss attempt and had expended less time in vigorous and total PA than those who were satisfied with their body shape. However, when adjusting for socio-demographic variables, logistic regression analysis revealed significant associations of BD with higher BMI, shorter membership duration of fitness club, and reduced dairy products and energy drinks consumption.ConclusionExcept for BMI and decreased dairy products and energy drinks consumption, many lifestyle behaviors did not associate with BD among Saudi females attending fitness centers. The findings can inform healthcare providers when intervention strategy is implicated for females with BD. Future studies should compare the associations of BD with lifestyle behaviors between males and females attending fitness centers and seeking weight loss. (shrink)
