I don't think we can classify people as wanting truth vs. wanting to be right. How can you be right if you don't have a sensible version of truth? Of course, none of us can ever have complete "truth." Truth is an abstract concept that we can only comprehend through speculation.
I think a more accurate analysis/common denominator of humans is that we all want something concrete to beleive. We are analytical creatures, and we do not like the unknown. That is why we have so many afterlife stories--we do not like the idea of the nothingness of death. Death--the ultimate unknown. Of course we want to be right about where we are going. Yet, at the same time, we long for our knowledge to be correct, not just "right." Do I make any sense?
