Choosing a topic that is too broad such as "AIDS" or "child abuse" is unworkable for two main reasons:
A. The information required to adequately understand the topic would take too much time
to gather, evaluate, and use.
B. The topic is too vast and complex to do it justice. A short paper or presentation would be superficial, lacking substance and depth.
Choosing a topic that is too narrow such as "holiday traffic patterns in Bellport Village" is unworkable for two main reasons:
A. The chances of finding sufficient information is doubtful.
B. The topic is insignificant to most people.
A. Examine the subject from a specific viewpoint/discipline:
• humanities (literature, music, art, etc.)
• sciences (biology, chemistry, physics, etc.)
• social sciences (psychology, sociology, anthropology, etc.)
