Hi. I'm doing a project on media bias and the effect on people in general; whether they can recognize it and how they react to it. IF anyone has any suggestions on it, I'd be very grateful. Basically, what I'm doing is first putting out a "pre-survey" to see what factors might influence people and then after showing them a powerpoint slide, asking them to fill out a post survey in which they fill in some questions. I'm thinking of having around 4 different powerpoint slides, each one being biased in one way or another. However, I can't find a topic to put out to the people in general. I was originally thinking about putting slides on Bush and Kerry but this may influence their answers. Any suggestions?

Thanks a lot
