Race differences in perceptions of discrimination are well documented, but questions remain about contextual- and individual-difference moderators of when White and Black Americans see racial bias. We examined how temporal framing (focusing on past decades or not), race, political party, and domain of discrimination influence discrimination perceptions. Temporal framing did not moderate perceptions for White or Black participants (Study 1). Perceived anti-White and anti-Black discrimination converged over time (from the 1950s to the present), but especially so among White participants (Studies 1 and 2). Domain of discrimination moderated perceptions, with White respondents perceiving the steepest rise in anti-White discrimination and the steepest decline in anti-Black discrimination in the education and employment domains (Study 2). Across both studies, only White Republicans reported that White Americans face more discrimination than Black Americans. This research extends the literature on racial and political divides in discrimination perceptions, and highlights variability in perceptions across discrimination domains.

对歧视的看法的种族差异有据可查，但关于白人和黑人美国人何时看到种族偏见的背景和个人差异主持人的问题仍然存在。我们研究了时间框架（是否关注过去几十年）、种族、政党和歧视领域如何影响歧视认知。时间框架并没有缓和白人或黑人参与者的看法（研究 1）。随着时间的推移（从 1950 年代到现在），感知到的反白人和反黑人歧视趋于一致，但在白人参与者中尤其如此（研究 1 和 2）。歧视领域缓和了看法，白人受访者认为教育和就业领域的反白人歧视上升幅度最大，反黑人歧视下降幅度最大（研究 2）。在这两项研究中，只有白人共和党人报告说，美国白人比美国黑人面临更多歧视。这项研究扩展了关于歧视认知中种族和政治分歧的文献，并强调了跨歧视领域的认知差异。
