Multiple point of view
Discourse employing multiple point of view (MPOV) has advantages over the so-called neutral point of view favored by journalism and encyclopedia editors, and may be easier to achieve than the natural point of view implied by the empirical methods of the sciences. Accordingly it may be one of the better compromises where agreement on fundamentals is not easy to achieve.
The usefulness of fiction, in particular science fiction and conspiracy fiction, to illustrate current political matters, is often thought to derive in part from its use of multiple point of view. But non-fiction such as interview or documentary styles can also employ these methods. And it is sometimes used in the scientific method by way of simulating an adversarial process:
Galileo, for example, employed dialogue style for discussing the "two world systems" of Ptolemy and Copernicus, each with their own implications and a character ("Sagredo" for the Copernican, and "Simplicio" for the Ptolemaic) to defend each vigorously.
