Attitudes towards aging include both positive and negative beliefs about older adults (Iverson et al., 2017; Palmore, 1999). Palmore’s (1998) Facts on Aging Quiz, a widely used assessment of knowledge about aging, also identifies common societal misconceptions about aging. Findings regarding age group differences in attitudes toward aging are mixed (Bodner et al., 2012; Cherry & Palmore, 2008; Rupp et al., 2005). The current study compared knowledge of aging, negative age bias, and positive age bias between young adults (18-35 years, n=268) and middle-aged adults (40-55 years; n=277). Middle-aged adults reported significantly greater average knowledge of aging than young adults (p=.019), although both groups had relatively low knowledge (MA: M=13.0, YA: M=12.2). Middle-aged adults also showed significantly less negative age bias (p
