While some research does seem like a waste of time in a scientific sense anecdotal evidence, as it is called, is not evidence. This makes properly done, peer reviewed, research necessary if one wants to expand research into another related field.
If one wants to become a respected researcher or at least conduct a study using proper methodology bias should be controlled for as best as possible and starting with baseless* assumptions is not the way to do it.
*Anecdotal evidence is seen as baseless in terms of research.
