What are the key strategies for formulating effective interview questions according to Chris Wallace?

According to Chris Wallace, thorough preparation is essential when formulating interview questions. He emphasizes that while interviewers may not know as much as their subjects about specific topics, they have the advantage of knowing what they'll ask in advance. Wallace stresses making questions 'bulletproof' by keeping them focused, narrow, and precisely phrased to prevent interviewees from exploiting imprecisions. Equally important is the follow-up question, which Wallace considers crucial for creating newsworthy moments. He notes that the initial question is sometimes almost a 'throwaway,' while the real value comes from carefully listening to responses and crafting targeted follow-ups. This approach allows interviewers to maintain control of the conversation and extract meaningful information even from challenging subjects.
