Over the weekend, ABC's 20/20 had a show on a couple experiements that were fascinating.

In one, the show hired four young actors, two boys and two girls, all 7 years old and dressed in everyday clothes. The children took turns standing on the corner of a well traveled street in a city near New York with various hidden cameras planted nearby.

The show was seeing who would stop to help these kids or who would just pass on by. In two days, more than 2,000 people just walked on by, even if the kid was crying, and only 47 people stopped to help the kid and see what was wrong.

Another experiment was on gay couples kissing in public or just showing affection. What would you do? What would be your reaction. Some people called the police. How scary is that?
