Attacking the person instead of the system, using urgency and authority. Almost every version of it fails if you stop and check on a number you already had.
The drawing that proves the sentence above. It is the same card that is in the book.
Think of it as
talking your way past the guard instead of picking the lock.
For example
A very urgent, very official voice needs you to act right now. You say you will call back on the number on your card. The urgency was the whole plan.
This is one card out of 275.
The hundred words you meet most are free — the whole set, animated, in one file that works with no internet.
Volume 1 has all 275 in fifteen chapters, with Staying Safe the largest chapter on purpose.
