I took Princeton review and all the people in my class (including me) took diagnostic tests. We all took the science curriculum and spoke English at home, but everyone (except the girl who was retaking) scored lower than a 25. I got a 21 (though I pulled this number up CONSIDERABLY after the prep course). For the last MCAT the average score was a 24 (8 in every section). 25 is better than average. Furthermore, as Brett pointed out earlier, many DO schools have averages far below 25 but they don't have 50% failure rates. So I guess someone with a 25 can succeed in medical school. The problem is, you don't think someone with a 25 can succeed, but you don't look at the information that tells you these individuals can. Usually when I think something, I try to verify. If I'm wrong, I change what I think. Because of application pressure, schools are able to choose people who have higher MCAT scores than the threshold for success. This inflates the minimum MCAT requirement. Not everyone can get in, so some qualified applicants are passed up.
I still don't think this is a good example. Sure, if you limit the definition of "gang members" to people who are in traditionally black street gangs (Crips and Bloods), the members will probably be black. This is not because all gang members are black, but because you chose black street gangs. Guess what? There are OTHER street gangs that are made up of different races. If you take a sample of all the street gangs, you'd start losing money really fast. Here's a list of NY street gangs starting with A:
* African Mafia
* American Guards
* Albanian Boys Incorporated
* Atlantic Guards
* American Born Chinese (ABC)
* Asian Boyz Gang (ABZ)
* Assyrian-Arab Soljaz
* Almighty_Gaylords
* Agat Blood Town
* ARMENIAN POWER (A.P)
For a comprehensive list of all street gangs in NY, you can visit
http://en.wikipedia.org/wiki/List_of_street_gangs
Here you can see there are Asian gangs, Armenian, Albanian, Arab, and (yes) Black gangs. And this is just the As of one city! Just think of the diversity you would find if you looked at ALL street gangs all across America--all the colors of the rainbow! But because you subscribe to stereotypes, you think all gang members are black and you treat all black people accordingly.
As for the terrorism, there are many non-Arab terrorist. People are terrorists for all sorts of reasons: here are a few terrorist groups who are not Arab:
Ku Klux Klan A racist organisation of mainly Anglosaxon Protestant Christians with a history of violence against Afro-Americans, Jewish People, and Catholics.
Lord's Resistance Army Christian/Pagan terrorist group
Jewish Defense League - United States
Shiv Sena A Hindu militant group, Shiv Sena or "The Army of Shiva the Destroyer"
Jemaah Islamiyah - Southeast Asia
Anti-Abortion Terrorists - United States
Aryan Nations
Most of the Arab terrorist groups on the list were just fronts for Al-Qaeda. Isn't learning fun? For a more comprehensive list of terrorist groups of all backgrounds go to
http://en.wikipedia.org/wiki/Terrorist_groups#Left-wing_terrorists
So you see, it's not that all terrorist are Arabs, it's just that the terrorist groups you think of first are Arabs. Better watch your back around all those Hindus, Sikhs, Extreme left wing Whites, Extreme right wing Whites, Indians, Africans, and Southeast Asians too. Or you could just treat everyone like a human being and understand most people aren't out to blow $hit up. As you can see, stereotypes do not justify negative racially related judgments.
