Strati’s SEI is good in my book but the descriptions do seem written for people that want to read about themselves. They may not be useful for someone outside of type. For example way she writes how IEI like to talk about how they use their contacts to get what they want makes it sound as if they’re manipulating people to get the position of manager when in reality it’s more like your IEI grandma telling you how she jumped the line at the bank because she knows the clerk.
