True, but others in this thread have noted that chaotic good characters are similar, if more well-intentioned. And, in general, good characters tend to have a superior attitude and inflexible thinking.
Totally disagree. "Lawful stupid" is a D&D phenomenon. In the real world, we can see puritanical zealotry for what it is. Sure paladins would have their fans, but most people would know better.
Conversely true neutral people simply do whatever they think is right, and are flexible and adaptable to the real world.
As any official writing on D&D alignments notes, they don't apply in reality.
