Irrational Strategies for Obtaining Happiness
The personality types which comprise the PTypes typology represent irrational strategies for obtaining happiness. These strategies are irrational because they pursue things not in our power and involve false judgments (Seddon, pg. 88) of what is good and evil (see G. Sterling). In other words, the irrational strategies consist of the pursuit of certain preferred indifferents or the avoidance of certain dispreferred indifferents. For more on this, see A Brief Theory of Bad Character.
But happiness is in our power.
Things Not In Our Power are Neither Good Nor Bad
