Racism is generally understood as either belief that different racial groups are characterized by intrinsic characteristics or abilities and that some such groups are therefore naturally superior to others, or as practices that discriminate against members of particular racial groups, for example by perpetuating unequal access to resources between groups.

The definition of racism is controversial both because there is little scholarly agreement about what the word "race" means, and because there is also little agreement about what does and doesn't constitute discrimination. Some definitions would have it that any assumption that a person's behavior would be influenced by their racial categorization is racist, regardless of how seemingly benign such assumptions might be. Other definitions would only include conscious malignant forms of discrimination. Among the questions about how to define racism are the question of whether to include forms of discrimination that are unintentional, such as making assumptions about preferences or abilities of others based on racial stereotypes, whether to include institutionalized forms of discrimination such as the circulation of racial stereotypes through the media and whether to include the socio-political dynamics of social stratification that sometimes have a racial component.

Jane Elliott (born 1933, Riceville, Iowa)^{[citation needed]} is an American teacher and anti-racism activist. She created the famous “blue-eyed/brown-eyed” exercise, first done with grade school children in the 1960s, and which later became the basis for her career in diversity training.

While there are variations of the story, the exercise Elliott developed for her third grade class in Riceville, Iowa was a result of Martin Luther King’s assassination. According to one biographer, on the evening of April 4, 1968, Jane Elliott turned on her television to find out about the assassination. One scene she says that she remembers vividly is that of a (white) reporter, with the microphone pointed toward a local black leader asking “When our leader (John F. Kennedy) was killed several years ago, his widow held us together. Who's going to control your people?” It was supposedly there, in her living room, that she decided to combine a lesson she had planned about Native Americans with the lesson done about King for February’s Hero of the Month. To tie the two, she would use the saying “Oh Great Spirit, keep me from ever judging a man until I have walked a mile in his moccasins.”

"A Whiter Shade of Pale" is the debut song by the British band Procol Harum, released 12 May 1967. The single reached number one in the UK Singles Chart on 8 June 1967, and stayed there for six weeks. Without much promotion, it reached #5 on the US charts, as well. It is one of the fewer than 30 all-time singles to have sold 10 million (or more) copies worldwide.^{[citation needed]}

With its haunting Bach-flavoured instrumental melody, soulful vocals, and unusual lyrics—by the song's co-authors Gary Brooker, Keith Reid, and Matthew Fisher-- "A Whiter Shade of Pale" reached #1 in several countries when released in 1967. In the years since, it has become an enduring classic. It was the most played song in the last 75 years in public places in the UK (as of 2009), and the United Kingdom performing rights group Phonographic Performance Limited in 2004 recognised it as the most-played record by British broadcasting of the past 70 years. Also in 2004, Rolling Stone placed "A Whiter Shade of Pale" #57 on its list of the 500 Greatest Songs of All Time.

The term black people is used in some socially-based systems of racial classification for humans of a dark-skinned phenotype, relative to other racial groups represented in a particular social context. Different societies apply different criteria regarding who is classified as "black", and often social variables such as class and socio-economic status also play a role, so that relatively dark-skinned people can be classified as white if they fulfill other social criteria of "whiteness" and relatively light-skinned people can be classified as black if they fulfill the social criteria for "blackness" in a particular setting.

As a biological phenotype being "black" is often associated with the very dark skin colors of some people who are classified as "black". But, particularly in the United States, the racial or ethnic classification also refers to people with all possible kinds of skin pigmentation from the darkest through to the very lightest skin colors, including albinos, if they are believed by others to have African ancestry, or to exhibit cultural traits associated with being "African-American". As a result, in the United States the term "black people" is not an indicator of skin color but of socially based racial classification.
