Introduction to Primary Research 155

Jared Schwab, an agricultural and biological engineering major at
Purdue, was interested in learning more about how writing and com-
munication took place in his field. His primary research included
interviewing a professional engineer and a student who was a senior
majoring in engineering. His secondary research included examining
journals, books, professional organizations, and writing guides within
the field of engineering.
Ethics of Primary Research
Both projects listed above included primary research on human partic-
ipants; therefore, Derek and Jared both had to consider research ethics
throughout their primary research process. As Earl Babbie writes in
The Practice of Social Research, throughout the early and middle parts
of the twentieth century researchers took advantage of participants
and treated them unethically. During World War II, Nazi doctors
performed heinous experiments on prisoners without their consent,
while in the U.S., a number of medical and psychological experiments
on caused patients undue mental and physical trauma and, in some
cases, death. Because of these and other similar events, many nations
have established ethical laws and guidelines for researchers who work
with human participants. In the United States, the guidelines for the
ethical treatment of human research participants are described in The
Belmont Report, released in 1979. Today, universities have Institutional
Review Boards (or IRBs) that oversee research. Students conducting
research as part of a class may not need permission from the univer–
sity’s IRB, although they still need to ensure that they follow ethical
guidelines in research. The following provides a brief overview of ethi-
cal considerations:
•Voluntary participation. The Belmont Report suggests that, in
most cases, you need to get permission from people before
you involve them in any primary research you are conduct–
ing. If you are doing a survey or interview, your participants
must first agree to fill out your survey or to be interviewed.
Consent for observations can be more complicated, and is dis-
cussed later in the essay.
