"I'm just going to use the boss's office while his away. No, don't call him. He won't thank you for bothering him while he's on holiday."
Telling you someone in authority says it's OK and that you don't need to check with them is a cruel technique as the suggestion that your boss will be angry with you makes you doubt your instinct which was to get confirmation.
"Others have already agreed so you don't need to get permission."
Have they really? Have you asked them or are these just persuasive lies? And why should you jump on the bandwagon anyway?
"You have to get this done today? Your boss really wants it finished."
Is that true or just persuasion and manipulation of the truth? Has your manager discussed the deadline with you directly? How can this person speak for your manager when surely they would ask you themselves if it was urgent?
These comments have come from persuasive business colleagues who know how to get their own way but it also feels like a pushy salesman:
"The deal ends today. You need to agree now so there isn't time to check elsewhere. I can only give you the discount if you sign up immediately."
Misleading offers to entice you to make a snap decision are sadly common in advertising and from salespeople who works on commission who need you more than you need them.
"No that was an old offer. It's [this, this and this]. I can arrange it all now. You need to make a decision. You don't want to miss out. This offer won't happen again. You won't beat this deal."
A better technique for opening a business conversation is to never assume that what you have will be wanted. That doesn't mean doubting you or your product but by saying, "I'm not sure if I can help" or "I'm not sure if you're the right person to speak to" reduces the pressure on that first conversation and makes you seem less desperate.
The Harvard Business Review found people lie more in emails than face to face and that seems very likely as it's always easier to write some things than say them. But, in return, it's also easier to ignore something in an email than when the recipient is standing in front of you.
This wonderful online guide to the Language of Persuasion explains really well how we become convinced to buy something we didn’t think we even wanted just by using the right techniques in the right ways. Being persuasive isn't about being aggressive and making someone feel uncomfortable; it's about getting the information across about the good points of a 'deal' in a way that makes the recipient feel they are making their own decision. No-one wants to be so subservient that control of their own life is reduced. But with the right persuasion everyone can be left feeling that they are a winner.
