Plagiarism in College Students

My topic is a pretty well known subject to most students. We've learned about plagiarism since we were little kids, so to most of us its almost common sense. Getting into the deeper meaning of why students turn to plagiarism and what the consequences are does raise some controversy though. Most conversations turn to the reasons behind plagiarism. Most student's know its the wrong thing to do, but almost all admit to slightly doing it once or twice. It's easy to get reactions and opinions on such a well known topic. The consequences of plagiarism are also widely known, so students can freely talk about their opinion if they feel the rules are fair or not. Most students comply that the rules are fair since we must agree with them, but some feel otherwise.

My only concern with my research process is when I create a survey, I can not be 100% sure students will be honest. Although students know they have plagiarized, many will not admit or want others to know they have. The survey will be anonymous, but some still are skeptical. So my only concern if getting the true statistics in.
