The president is having a press conference. Suddenly someone jumps up
and shouts, “Is it true that you are having an affair with your personal
secretary?” He has a few options now. He can protest loudly, “Do not be ridiculous!” and the papers will read, "President denies affair with
secretary.” Or he can have the reporter thrown out: “President ejects
reporter who asks about his affair with secretary.” Or he can look straight at the reporter, make it clear he heard the question, and then pivot to “Next
question please.” He can refuse to dignify the question with a response
(Papantonio 2013).
From the book 'Overcoming Unwanted Intrusive Thoughts' about how responding to the thoughts gives them weight. :)
