I wouldn't exactly call the basis of you opinion very sceintific. Listen, any religious organization is going to attract oddballs. My point is that Opus Dei, is primarily a service organization, and the people who run it are actually pretty mainstream. What I did for them was give art lessons to underprivledged kids in the Bronx.
Well clearly both of our impressions and stories are subjective and anecdotal. I doubt Opus Dei or the LT's would allow any independant researcher access to Opus Dei or LT adherents except under very controlled circumstances.
