This is true for writing in general, but much less so for academic writing. This does not mean one should not pursue brevity. One way in which brevity can be achieved is to avoid including in the title any description of what kind of text is to follow. Thus titles such as the following should be edited back to their essence:
*Study of the influence of the political essays by Mark Helprin on contemporary politics.
Helprin's influence on contemporary politics
Similarly for: An Investigation of, Some Aspects of, …
The requirement that the title should be immediately understandable follows from the fact that it plays such a major part in helping the potential reader decide whether he will or will not read the text. If a title fails to provide a context, explicitly or implicitly, and does not orient the reader towards a particular subject matter within that context, there is a certain chance that the reader may nevertheless be intrigued and will read on; but in the case of argued prose, there is a much greater chance that the reader will dismiss the text as fanciful and unbusinesslike.
Focus structures: jumping the queue
Indeed, in these days of international and immediate electronic access to texts through Internet and other forms of computer-based bibliographic searching, writers are under increasing pressure to produce unambiguous titles, so that potential readers can with confidence select texts relevant to their needs.
The third observation about effective titles is that they should be neutral. It is counterproductive to confront the reader with your opinion in the title –after all, why should he believe you? it is much better to offer, as outlined above. an indication of the field of inquiry (the Theme) placed in a recognizable context (the Frame). This is why titles do not generally appear as full sentences, since a sentence expresses a proposition, i.e. a judgment. Titles are not designed to express the result of the thought process underlying the text: rather. they offer a starting point for the reader's task of reconstructing that thought process on the basis of the information presented within the text. Thus titles such as the following are inappropriate headings:
*Analysis of the Works of an amazing author: Mark Helprin
*Britain is Going to the Dogs
Much better would be:
Aesthetics in Mark Helprin's oeuvre.
Recent Developments in the British Economy
Ian McEwan's "Atonement": balancing on the edge of Ethics?
Hemingway's "In our Time": Novel or Short story cycle?
