====== Social Constraint Theory ======
An example of inductive generated social theory in Earl Babbie's book.
Why do people use marijuana?

  * 마리화나 예
  * 흡연자와 비흡연자: 동등한 학업성적, 학교활동, 대학생활적응
  * But,
    * 여성 < 남성
    * 동양계 < 비동양계
    * 집 < 자취
<blockquote>Overall, then, a “social constraints” theory was offered as the explanation for observed differences in the likelihood of smoking marijuana. The more constraints a student had, the less likely he or she would be to smoke marijuana. It bears repeating that the researchers had no thoughts about such a theory when their research began. The theory came from an examination of the data.</blockquote>
