There is hope, one should first look at why do people do research. The essence of research is to bring new concepts and findings that other people did not know about. Hence there is hope for perfect research...
Yes, there is no such thing as perfect, in the world. For an example, if given a story to analyse to 10 people , you will receive 10 different answers. Each person will have his own perception. So there no perfect reaserch. It all depends on individual's thought and situation.
There is hope of doing perfect research if and only if the knowledge on the research topic is thorough and with natures boundless mysteries as yet there is no perfect knowledge that is within the limits of man's brain
As we have been marching onwards, research has become undeniably indispensable and essential for advancement in myriad fields. It has produced a lot of useful innovations in science and technology, and in all other fields such as in psychology, political science, and in economics. Hence, since it has become a great deal for humankind to produce knowledge, it has been a constant aspiration for us to enhance methods or processes of research. Although research results may appear promising, nevertheless, their reliability or validity has always been threatened with the presence of errors and biases in the study. Thus, it has been argued that there is no hope of doing a perfect research.
