INTRODUCTION: WHAT IS RESEARCH?
As an established body of knowledge, research is the accumulation of evidence by researchers over time. It provides a background against which claims for knowledge can be evaluated, and provides a way for researchers to communicate and compare their findings.
Research as a collection of methods, tools, and techniques forms the basis for most research texts and courses in research; its methods are what set it apart from other ways of acquiring knowledge.
As a purposeful or functional activity, research must justify the resources
it consumes to accomplish its purposes.
When we use empirical research, we assume that it will yield more reliable and valid information about complex natural phenomena, including humanity. Empirical research is concerned with describing, explaining, and predicting natural phenomena. However, its understanding will always be partial, incomplete, and probabilistic. And some questions cannot be answered by this process.
Empirical research is guided by evidence obtained in systematic and controlled observations. It is a means of decreasing ignorance about natural phenomena. Social sciences attempt to use the same approaches and methods as the physical sciences, but they fail to reach the same level of objectivity because it is more difficult to come to inter-subjective agreement about the object of study.
Objectivity is agreement among expert judges on what is observed.
Objectivity is a procedure or a method. It does not refer to qualities
or characteristics of a person doing research. An objective test
does not mean that the test itself is unbiased, but that nearly anyone
could arrive at the same score using the test as a measuring device.
Objectivity also refers to the controlled experimental situation which
produces replicable findings.
Research, as a public enterprise, is unique among social activities
in its insistence on objectivity--which is difficult given human characteristics
and limitations. Objectivity has little importance in and of itself,
but it gives research its special character because it provides more trustworthy
explanations of natural phenomena than other ways of knowing. Objectivity
is always a matter of degree, but it is indispensable. It protects
research from the personal biases of researchers, by allowing replication
and generally producing the same or similar results. The use of technology
has increased the agreement among expert judgement because machines are
less likely than people to be affected by the process of observation itself.
Criticisms of empirical research include the humanistic critique against the practice of objectivity, which makes the research process abstract, remote, and cold. It ignores human values and needs. The knowledge gained is only partial and reductionistic. It ignores intuition and spiritual values.
Other arguments include the critique that objectivism is impossible, since we are ruled by our values, motives, history, and cultural context. Research can become a tool for those in power. Researchers don't stop to consider the ends to which their research could be put.
Some argue that humans, groups, and organizations cannot be measured; they are wholes that cannot be reduced to quantitative parts. Or, anything that can be measured by numbers is only trivial. Or, statistical significance is not the same as real meaning.
However, researchers argue that there are no absolute truths, only relatively more or less reliable and valid knowledge. Objective procedures increase the probability of obtaining more valid and more reliable knowledge. While people are not objective, research can be made more objective by following the rules of objectivity. These include:
