When we think of hacking, we think of a tech-savvy dude breaking into computer systems to steal data. But hackers can also take the form of "social engineers" who get what they want by building rapport and penetrating psychological defenses.

My guest is an expert and pioneer in the area of human hacking, and shows individuals and companies the weaknesses of their security systems by breaking into their offices and computers, not by bypassing pass codes and firewalls, but simply by walking in the front door, and knowing how to ask for and receive access from the humans who run the show

His name is Chris Hadnagy, and he's the author of Human Hacking: Win Friends, Influence People, and Leave Them Better Off for Having Met You, which takes the social engineering principles con men and malicious social hackers use to breach security systems and steal data, and shows the average person how to use them for positive ends in their personal and professional relationships. Today on the show, Chris shares how assessing which of four styles of communication someone prefers can help you better connect with them, why you should approach every interaction knowing your pretext, the keys for building rapport, and the difference between manipulation and influence. We end our conversation with tips on the art of elicitation -- how to get information from someone without directly asking for it.
