Socratic irony can be seen as a tactical maneuver of sorts. It's most practical iteration is in the "Socratic method" of teaching, which has been adopted by many prestigious universities throughout the world as a method of student-facilitated education. The professor, the supposed possessor of knowledge, never answers questions, nor does he out-rightly explain the concepts required to understand the course material, but rather poses questions to his students that revolves around the course material, and as such, the students are expected to have arrived in class after having studied the required reading to be able to provide the information to others in their class. The feigned "ignorance" on the part of the professor becomes a means to an end. The class gains the necessary information to learn the course material. On the other hand, Socratic irony can be used for far less noble means than intellectual edification. One sees Socratic irony used quite often to get one's way, or to avoid discussing an uncomfortable topic. Ignorance is bliss so they say, and sometimes pretending that you don't have information can give you the upper hand in an argument, or it can be your get out of jail free card (E.G. "Well gee, I have no idea who put the empty milk carton back in the refrigerator"). There are, however, common and beneficent ways people use Socratic irony. If for example, a child asks his parents about the present underneath their Christmas tree and the parents exclaim, "I have no idea how those gifts got there!" one can see how Socratic irony can play a very important purpose in many American traditions.
