In my experience, Psychology books come in two primary flavors.
Normative View / Normative Scripts
This flavors takes the Normative View and presents the way the world should work. This flavor then compounds that folly, if not deleterious world view by providing scripts of how to act in this erroneous world view
Expected Results: Life time of pain, underperformance and/or failure.
Positive View / Normative Scripts
This flavors takes the Positive View and presents the way the world does work. This flavor is promising in that respect. However, this flavor then advocates that we use scripts for the Normative View and actually goes further and admonishes that no one wants to live in a Positive View world, therefore, we shouldn't utilize scripts that would be advantageous or powerful in the Positive world view.
As a result, we end up using the very same scripts as found and advocated in Flavor #1 -- that we respond to how the world should be rather than how it is.
Result: Life time of pain, underperformance and/or failure.
