Proving your case without compelling arguments is quite a difficult task.
However, if you use certain psychological tricks, your chances of achieving the desired result will increase.
What techniques should a person pay attention to if he wants to become more persuasive?
Maximum honesty
This approach can hardly be called a “psychological trick”.
This is simply an important rule of communication. Following the recommendation will almost certainly lead to the interlocutor believing you.
Try not to lie even in details. Be as straightforward and honest as possible. And then you will not be caught in contradictions. Because there are none.
And one more thing: a person who answers questions honestly is usually not nervous. And calmness helps to look convincing.
Agreeing with the opponent
But what should you do if you still have to lie somewhere? Or if you argue about some abstract things or about something that cannot be verified on the spot?
In this case, use this technique: agree with your interlocutor on some insignificant point.
Your opponent will come to the erroneous conclusion that he has started to win the argument.
Once it becomes clear that you have managed to lull your interlocutor's vigilance, use the argument that seems most convincing.
Compliments
Is your opponent clearly negative and therefore ignores all your arguments?
There is a way out in this case too. Please your interlocutor with flattering words. And then the person will probably stop being unyielding.
An important point: compliments should not be intrusive.
