A random sample of 1,276 U.S. adults were surveyed about their perceptions of differences for Blacks in the United States based on discrimination, ability to learn, opportunities for education, and willpower. Those with little education and extensive education were more aware of discrimination for Blacks. Higher levels of education as well as professional and managerial work increased awareness that Blacks have the same ability to learn as Whites and that Blacks lack equitable opportunities for an education. Those with less education and those employed in technical and manual labor were the most likely to say Blacks lacked willpower.

美国黑人的教育水平、职业分类和差异认知

对 1,276 名美国成年人的随机样本进行了调查，了解他们对美国黑人在歧视、学习能力、教育机会和意志力方面的差异的看法。那些受过少教育和广泛教育的人更意识到对黑人的歧视。更高水平的教育以及专业和管理工作提高了人们的意识，即黑人具有与白人相同的学习能力，并且黑人缺乏平等的教育机会。那些受教育程度较低以及从事技术和体力劳动的人最有可能认为黑人缺乏意志力。
