Depends on the context. I'm slower than I used to be (aging I suppose), but, uh: 1) Prep/rehearsal 2) Delay ("I'll have that for you on [later]") 3) Snark ("If it doesn't matter let's just flip for it") 4) Silence, then spend the next 8 weeks mentally rehearsing and regretting and beating myself up If it's literally just "quick wit", sometimes I have it, sometimes I don't, my wife always destroys me and I can only acknowledge greatness. For myself, outside of prep/rehearsal, I generally only have "quick answers" if it's a situation where I either have a heuristic I trust ("Budget for that department needs to be 20% of top line revenue in most situations"), or a value that makes the decision for me ("We can 10x our profits if we poison these 17 children, should we do it?" has a quick "No").
