Sociology and Phycology

Yahoo Answers accepts questions that few other answer-all-questions services do. Here’s an example: “What is the difference between sociology and phycology?”

Yahoo Answers says that the former “tends to examine groups of persons (societies), communities, and nations” while the latter “examines more of the workings of the human mind, why persons think and behave as they do.”

That is a non-traditional answer. Most older reference works (such at the book pictured here, at right), and even some newer ones, say that phycology is the study of algae.
