Registered replication report: a large multilab cross-cultural conceptual replication of Turri, Buckwalter, & Blouw (2015)

According to the Justified True Belief account of knowledge (JTB), a person can only truly know something if they have a belief that is both justified and true (i.e., knowledge is justified true belief). This account was challenged by Gettier (1963), who argued that JTB does not explain knowledge attributions in certain situations, later called Gettier-type cases, wherein a protagonist is justified in believing something to be true, but their belief was only correct due to luck. Lay people may not attribute knowledge to protagonists with justified but only luckily true beliefs. While some research has found evidence for these so-called Gettier intuitions (e.g., Machery et al., 2017a), Turri et al. (2015) found no evidence that participants attributed knowledge in a counterfeit-object Gettier-type case differently than in a matched case of justified true belief. In a large-scale, cross-cultural conceptual replication of Turri and colleagues’ (2015) Experiment 1 (N = 4,724) using a within-participants design and three vignettes across 19 geopolitical regions, we did find evidence for Gettier intuitions; participants were 1.86 times more likely to attribute knowledge to protagonists in standard cases of justified true belief than to protagonists in Gettier-type cases. These results suggest that Gettier intuitions may be detectable across different scenarios and cultural contexts. However, the size of the Gettier intuition effect did vary by vignette, and the Turri et al. (2015) vignette produced the smallest effect, which was similar in size to that observed in the original study. Differences across vignettes suggest epistemic intuitions may also depend on contextual factors unrelated to the criteria of knowledge, such as the characteristics of the protagonist being evaluated

ORAL MANIFESTATIONS IN PRIMARY PEDIATRIC VASCULITIS

Vasculitis are disorders characterized by the presence of an inflammatory process in the blood vessel wall, resulting in damage or necroses of certain tissues or organs. Numerous clinical symptoms, ranging from acute localized hypersensitivity reactions to severe auto-immune systemic disorders that are incurable and life-threatening, can be attributed to the types and locations of affected arteries as well as the level of inflammation. Typical oral or facial symptoms of several forms of vasculitis can help in an early diagnosis of vasculitis. IgA vasculitis and Kawasaki disease (KD) are the two predominant types of pediatric vasculitis that involve the mouth, followed by ANCA vasculitis. Furthermore, SLE, a connective tissue disease, is one of the most prevalent autoimmune illnesses in children and can proceed rapidly across multiple organs or start mildly and gradually. Numerous more systemic conditions, such as infection, autoinflammatory disorders and neoplasia, can also primary or secondary localize in the oral cavity, infections being more frequent. Many various professionals, including dentists, family physicians, pediatricians, rheumatologists, hematologists, gastroenterologists, and otorhinolaryngologists, examine and treat children with oral symptoms. In 87.7% of patients overall and over 90% of patients with KD and IgA vasculitis (formerly known as Henoch-Schönlein purpura), cutaneous involvement was observed. Recurrent oral aphthous ulcers were present in all Behçet syndrome patients (1)
