This actually makes a lot of sense.....

The two biggest barriers to good decision making are your ego and your blind spots. ...

     Once you understand how your a) logical/conscious you and b) emotional/subconscious you fight with each other, you can imagine what it's like when your two yous deal with other people and their own two "thems."  It's a mess.  Those lower level selves are like attack dogs - they want to fight even when their higher level selves want to figure things out.  This is very confusing because you and the people you are dealing with typically don't even know that these lower-level beasts exist, never mind that they're trying to hijack everyone's behavior.
