It's like the good old trick to get an answer on Reddit:

Create Account #1.

Ask your question.

Wait.

Create Account #2.

Post a confidently wrong answer.

Watch 37 people rush in to correct you.

Another reason is to refine your point of view, which is most effectively done when it is challenged.
