My research method

My topic is racism against black Americans. I am very interested in finding out how much people actually know about current racism or if people have experienced it. That is why i am going to do a survey. I want to find out if other people are interested in this topic, and if people believe something needs to be done about racism. i also wanted to do the naturalistic observation method, but i feel like in the area we live in i will not learn much. i feel like people are more secretive and polite about their thoughts on other races.
