Ways Narcissists, Sociopaths, and Toxic People Blend into Society

Social Adaptation Tactics
1. Pretending
It’s hardly shocking to anyone that narcissists lie, but in the context of social adaptation, pretending is a big part of it. You’ve probably heard the phrase, “Fake it till you make it.” Being fake is the narcissist’s life motto.
They pretend about anything and everything: that they are virtuous, successful, busy, in demand, happy, courageous, talented, caring, generous, serious, wise, trustworthy, and all around wonderful.
A common example is buying expensive clothes, or accessories, or gadgets, or vehicles, or simply lying about their professional success—all to appear rich and successful in order to sell others whatever they’re selling. Or, pretending to be a loving parent by talking about it online and posting pictures, and being in the community, and giving parenting advice, and otherwise painting a social picture of how great of a parent they are when they actually aren’t great at all.
These are just two examples, but there are hundreds.
Some people can see through all the smoke and mirrors immediately, while for others it takes some time. But for way many, all of it may seem legitimate.
