Benefits of Knowing Your Dark Side

 The author lists a few benefits of getting to know your dark side, including:

1. You become of how criticism of others is often a defense mechanism. Sometimes we accuse others of our own flaws.
2. Understand how your words sometimes hide fear and anxiety, jealousy and envy
3. You become aware of уоur fears аnd anxieties
4. Better understand our relationships with others
5. Accepting ourselves fully
6. Freeing of guilt 

Basically, it’s about self-awareness.
When you become more self-aware, you learn the motivations behind your actions and you can also better work at changing and improving yourself.

This is also a point that Robert Greene makes in The Laws of Human Nature.

 Review

Dark Psychology 101 is a very short text and it doesn’t really teach much about dark psychology.
Or about psychology in general, for that matter.

I found it tautological and self-referential and rather empty.

The author says “how great this or that technique works”, but then offers no proof, no study, no example… Nothing to either back up the claim or actually explain the technique.

If you are looking for wisdom and depth of information you might not find much here.
Lots of driveling, and few little information.
