Why Your Mind Goes Blank in High-Stakes Conversations, According to a New Leadership Book
You know your material. You've rehearsed the story, you know the number you want to hit, and then you're in the room and it happens anyway: the pause that goes on too long, the answer that comes out scrambled, the point you meant to make that just evaporates. That's not a preparation problem. According to economist and executive coach Caroline Webb, it's a brain problem, and her new book explains exactly what's going on and what actually fixes it.
Stress is a prediction, not a feeling
Webb's book, Leadership Intelligence: Science-Backed Strategies for Mastering 21 Everyday Management Challenges, was published this month and built around three decades of coaching senior executives through exactly these moments. In an interview about the book, Webb puts it plainly: stress "is very much the brain's prediction that a situation is going to be difficult and unmanageable." Once the brain makes that call, it shifts into a defensive stress response, and Webb notes that when it does, "there's less activity in the central executive network, and that means it's much harder to think clearly."
That's the part worth sitting with. The blank isn't a sign you didn't know the answer. It's your brain deciding, in real time, that the situation is unmanageable, and pulling resources away from the exact network you need to speak clearly under pressure. An interview panel, a salary counteroffer, a tough client call, all of these can trigger the same prediction, regardless of how much you actually know.
Manageable beats calm
The instinct most advice defaults to is "stay calm," but Webb's framing points somewhere more useful. The brain isn't asking whether you feel relaxed. It's asking whether the situation is manageable. You can be nervous and still keep your central executive network online, as long as nothing in the room registers as unfamiliar or out of your control. That reframes what interview and negotiation prep is actually for. It's not about memorizing more content. It's about removing the unknowns that make your brain flag the moment as a threat in the first place.
How to make the room feel manageable before you're in it
-
Rehearse out loud, not in your head. Silent run-throughs leave your brain guessing what it'll actually sound like to speak the answer. Saying it out loud, more than once, converts an unknown into something familiar, which is exactly what lowers the threat prediction.
-
Simulate the real format. If it's a video interview, practice on video. If it's a phone negotiation, practice on the phone without notes in front of you. The closer your rehearsal matches the actual conditions, the less novel the real thing feels when it happens.
-
Script your opening ten seconds. You don't need a scripted answer, but you do need an anchor. A prepared first line for your toughest question or your opening counteroffer gives your brain a known, manageable starting point instead of a cold, unpredictable one.
-
Prepare a recovery line, on purpose. "Let me take a second to think that through" is a normal, professional sentence, but only if you've said it before and know it won't derail you. Practicing your recovery move turns a blank moment from a crisis into a planned pause.
-
Practice with feedback, not just repetition. Rehearsing the same answer without a read on how it actually lands doesn't close the biggest unknown: whether it's working. A tool like SpeechPlus that scores your delivery and flags what to fix gives you real data before the stakes are real, which is what actually makes the moment feel manageable instead of merely rehearsed.
The bottom line
You don't go blank in an interview or a negotiation because you're unprepared on the substance. You go blank because your brain has decided, often wrongly, that the situation is unmanageable, and it starts pulling resources from the exact system you need to think and speak clearly. The fix isn't trying harder to feel calm in the moment. It's doing the work beforehand, out loud, in the real format, with real feedback, so that by the time you're in the room, there's nothing left for your brain to flag as unknown.
