Several basic "principles" or reasons make psychological social engineering effective. These include authority, intimidation, consensus/social proof, scar- city, urgency, familiarity/liking, and trust.

Create two additional scenarios, such as an attacker impersonating a help desk employee who wants access to an employee's protected information, and create a dialog example for at least 3 of the 7 principles.
