When discussing the various types of research methods available to psychologists, most psychologists would agree that __________.

A) an experiment that provides conclusions about causation is always the best approach to answering a question
B) psychologists can rarely conduct true experiments because they cannot use random assignment
C) each type of method has advantages and disadvantages, and the question to be asked dictates the method used
D) observational methods can only be used with children

This is the most commonly accepted view among psychologists, as each type of research method (e.g. case studies, surveys, experiments, etc.) has its strengths and weaknesses, and the choice of method should depend on the research question being investigated. While experiments that establish causation are often preferred, such experiments are not always feasible or ethical, and observational or correlational methods may be necessary. Random assignment is ideal in experiments, but it is not always possible, and alternative designs may be used instead. Finally, observational methods can be used with participants of all ages, not just children.
