Research and study result in erudition, a state of being well versed in one's chosen fields. Once one has mastered an area of work, it becomes possible to philosophize based on what one knows.
We often hear of waxing philosophical. Most people can wax philosophical, and it is probably healthy behaviour. Not everyone can erudite philosophical, and it is probably likely to empty the room. The reason is that many people are afraid of the eruditeness. As one becomes more erudite, the population of equals deminishes, but the paradox is that the pool of hopefuls enlarges. Eventually, the erudite individual becomes lost in an enlarge field of erudite being crowding in on each other.
