“possibility strategy.” An example might be “I know it was a while ago, but is it possible that the two of you might have met?” There are no guarantees here, but people often recognize the conundrum you’re putting them in: It’s often nonsensical to claim that something is impossible. So, if you’re able to cross that first hurdle by getting the person to acknowledge it’s possible, you might continue to use the possibility strategy, or you may be able to shift it to reality: “Okay, what do you remember about that meeting?”
