Hypotheses are formed from examination of previous research findings, sometimes by thorough reanalysis of existing knowledge, including possible anomalous findings in earlier research, or sometimes by serendipitous observations. From whichever process an idea for research arises, development of a clear hypothesis is essential before an experiment is undertaken. There are some scientists who believe there is value in the ‘look-and-see’ type approach. Although this can sometimes be helpful in the process of scientific discovery, we believe strongly that the best scientific outcomes result from the documentation of an objective hypothesis that can be tested by experimentation. Outcomes from investigations into largely unknown areas of knowledge for which the ‘look-and-see’ approach is sometimes advocated, we believe will be improved if based on a formulated hypothesis.
