People lie for all kinds of reasons, sometimes because they think it’s in the listener’s best interest.
That isn’t their call to make and you should always pay attention to the details and take information with a pinch of salt. Most habitual liars aren’t really even lying to you, they are trying to convince themselves of some imagined reality.
The reasons aren’t that important, being able to recognize when someone is feeding you a lie is more important.
1. They Quickly Change The Subject
Once a liar has spun a shaky story about a particular subject, they will try to change the focus, to avoid detection. They will change the subject often to keep the upper ground in their hands. They avoid subjects they don’t know well and try to keep the conversation in their control.
2. They Change Their Story Often
As they created a fictional series of events for a specific purpose, as their needs change they need to adapt a new version of their story. Ask questions and pay attention to the details and sequence of events to reveal its validity.
3. They Are Always Nervous
They are afraid that someone will call them out on their bullshit. This fear leaves them in a continually anxious state. They could also be nervous because they are always fear the imagined opinions of others. They lie to combat this fear, trying to raise other’s opinions of them.
4. Their Stories Don’t Quite Add Up
The recollections of a liar are very inconsistent. They are focused on certain aspects of their story, so they neglect the basic tenets of common sense.
5. Quick To Go On The Defensive
They are always feeling guilty or at least aware of how much they are lying. As a result their defenses are always up or ready to go up in a flash in case people catch on.
