The final score in your dissertation paper is the sum total of the score in various other aspects, chief among them being originality and creativity. For this reason, you should avoid the topics which have been written by many times by many people. Some sociology dissertation ideas are so obvious to your supervisor and so they will not impress them.

Other titles should be avoided because they have been overtaken by events, for example, researching on whether U.S. white population can vote for Black president, since the election of Barack Obama in 2008 concluded this debate.
