The trait of being excited and pleased by novelty. Common among most hackers, SF fans, and members of several other connected leading-edge subcultures, including the pro-technology ‘Whole Earth’ wing of the ecology movement, space activists, many members of Mensa, and the Discordian/neo-pagan underground (see geek). All these groups overlap heavily and (where evidence is available) seem to share characteristic hacker tropisms for science fiction, music, and oriental food. The opposite tendency is neophobia.
