I'm a nerd and proud of it.
However, the term that might better fit the paleo adherents is 'openness to experience'. In psychology, there is a scale commonly referred to as 'The Big 5' which measures: Extraversion, Neuroticism, Conscientiousness, Agreeableness, and Openness to Experience. The latter being defined as:
"Openness is a general appreciation for art, emotion, adventure, unusual ideas, imagination, curiosity, and variety of experience. The trait distinguishes imaginative people from down-to-earth, conventional people. People who are open to experience are intellectually curious, appreciative of art, and sensitive to beauty. They tend to be, compared to closed people, more creative and more aware of their feelings. They are more likely to hold unconventional beliefs.
People with low scores on openness tend to have more conventional, traditional interests. They prefer the plain, straightforward, and obvious over the complex, ambiguous, and subtle. They may regard the arts and sciences with suspicion or even view these endeavors as uninteresting." Source: http://en.wikipedia.org/wiki/Big_Five_personality_traits#Openness_to_experience
It's also been correlated with intelligence, characteristics of geeks, nerds, and eccentrics, unless I'm mistaken.
