What Are Research Methods?
Research methods are the tools, techniques, protocols, and strategies that investigators and methodological communities use to conduct research. The most important esearch methods are summarized below.
Research methods are a social, rhetorical construct. Different academic and professional communities—e.g., mathematics, psychology, physics, engineering, or business—employ unique research methods. A primary focus of training in academic and professional disciplines concerns learning how to use disciplinary-specific methods, tools, protocols, and processes for gathering and assessing information. For instance, an anthropologist’s account of kinship patterns in a tribe of Native Americans bears almost no resemblance to a cognitive psychologist’s investigation of sensory responses to light stimuli.
Whether research results, truth claims, are understood or judged to be valid or convincing depends to a great extent on whether the investigator follows the tacit and explicit guidelines a discourse community considers appropriate for a particular research question and rhetorical situation. This is why rhetorical reasoning (especially audience awareness) plays such a formative role in the selection of research methods.
Research methods are not necessarily paired with particular methodologies, epistemological values, such as the rejection of positivism. Rather, methodological communities may employ the same methods yet hold contrary assumptions about the sort of knowledge those methods produce. For instance, a researcher could argue a case study creates universal knowledge—insights that transcend individuals, cultures, and historical periods. For instance, based on his therapy notes, Freud theorized we all have an id, ego, and superego. Jung suggested we all play archetypal roles including the hero, the shadow, the anima and animus. In contrast, another researcher could conduct a case study with similar subjects and yet argue the insights gleaned from the research do not illustrate universal knowledge—i.e., the results are stories, narratives, that provide robust details about the subjects interviewed . . . and nothing more.
Research Methods are constantly changing in response to new technologies. Eager to develop new knowledge or test knowledge claims, investigators experiment with new methods as technologies evolve. For example, the internet enables investigators to conduct worldwide research with online survey tools and video conferencing tools. Businesses are working with big data and analytics to commercialize data about consumers habits as they traverse the internet or purchase items in the world. Machine learning theorists are looking at how people write to develop artificial intelligence so technologies like Amazon’s Alexa can speak with humans.
Research Methods are evolving in response to new cultural mores. Communities of practice reconsider ethical principles and engage in dialectics regarding best practices. For example, capturing gorillas and studying them in cages might have been considered good research in the 1920s. The work of later researchers like Dian Fossey, however, demonstrated how animals might be better understood in their natural environment. Today, research based on observations of wild animals in captivity would gain little support or interest.
Consumers of research studies are wise to evaluate research methods. As a consumer of research, you are wise to critically evaluate a researcher’s methods. You would, for example, take your doctor’s diagnosis of a life-threatening disease more seriously than a fortune teller’s prediction of an early death. What distinguishes a physician’s prognosis from a fortune teller’s prophecy are research methods: the doctor may be looking at the results of your physical, blood work, x rays, CT Scans, MRI, or family history, whereas the fortune teller may be gazing into a crystal ball, pendulum, Tarot cars, or astrological charts.
Why Does An Understanding of Research Methods Matter?
If you are doing more than writing an essay that relies on sources, then you can benefit from understanding why there are different research methods.
- Learn more about how academic and professional researchers employ diverse research methods.
- Understand the philosophical assumptions that inform researchers in different disciplines.
Academic disciplines—for example, mathematics, psychology, physics, engineering, or business—have different ways of conducting and evaluating research. An anthropologist’s account of kinship patterns in a tribe of Native Americans bears almost no resemblance to a cognitive psychologist’s investigation of sensory responses to light stimuli. Even within a particular academic discipline, researchers may disagree over what makes good research. Different researchers employ different research methodologies because they have opposing, sometimes contradictory ideas, about what constitutes a valid knowledge claim. Not only do people disagree about appropriate methods of research, but their ideas may change over time. Conceptions about knowledge, available technologies, and research practices influence each other and change constantly. For example, capturing gorillas and studying them in cages might have been considered good research in the 1920s. The work of later researchers like Dian Fossey, however, demonstrated how animals might be better understood in their natural environment. Today, research based on observations of wild animals in captivity would gain little support or interest.
