Research Literature Quality and the Preponderance of Evidence

News reports and internet media feeds about new studies always come up on a daily basis with each piece meant to validate the previous information that was released1. Sometimes, the new studies findings contradict the findings of previous studies and such contradictions result in the need to ascertain the truth in all information being released. Evidence found among the thousands of pieces of information should be evaluated in specific ways to discern the truth. One of them involves screening the information. This entails the author getting to pre-evaluate sources of the information concerning the topic that he or she wants to write about1. The researcher should be fully aware of his or her objectives regarding facts, arguments, descriptions, statistics, eyewitness reports, and opinions that he or she wants to form part of the evidence backing up the information being collected.

The researcher should be able to discern the purpose of the research that he or she is doing whether it is to generate new ideas or validate a particular position. As result, the researcher can screen through the information found in these sources effectively and in the shortest times possible against his or her research objective(s). The researcher should also be able to select sources that are reliable in a manner that depicts some sense of experience1. He or she should be fully aware of what kind of source would be considered plausible enough to provide the necessary information to support the whole aim of the research being undertaken. This will eliminate any use of malicious sources during the whole process by the researcher.

All data should not be considered equally since not all data is created equally. Every research being undertaken in different fields share the scientific method of facilitating the research2. The difference comes in where the methods are being used in facilitating the research are being applied. There is diversification on how data is developed with some kinds of data being developed through collaborations while others are being developed single-handedly by specific figures.

Quality research normally involves the research material getting to undergo peer reviews undertaken by accomplished researchers to evaluate the relevance of the researched material2. Quality researched materials always contain full descriptions on the subjects being handled all to make sure that the right conclusions are sourced from the information developed by the researcher. It is important for a researcher to compare research methods to make sure that he or she gets to gather the necessary qualitative data or quantitative data required. Credibility is also an aspect that determines the quality of the research being undertaken2. This means that information sources used to facilitate any research process should be credible enough to be used in terms of containing valid information.

Quality research is also measured by standards that make sure that the information contained in the research can reproduce. This means that once the research process has been finalized, the information developed during the research should have the ability to be cited from relevant sources. This goes to show that information contained in the research material is dependable and accurate.

Credible sources for public health research materials should be published, peer-reviewed and scientifically developed journals. Any source that does not encompass these three aspects in the kind of information it contains and provides should be avoided since information in such sources have the potential of being biased and corrupted.
