One Brow, am i correct that according to the law in most of the countries - every person can be hired with the title "scientist"? I.e the scientist term/title is not regulated unlike CEO or doctor (at least in Estonia everybody, who has officialy graduated an university as a doctor for example orthopedist, gets an unique doctor's ID from the government and is put on a special database).
Am i scientist, if a company that belongs to my wife, hires me to research new accounting (she has an one-person accounting company) technologies?
IMHO, at least in my country there seems to be enough persons, who work at some university, claim to be scientist, however, most of the research seems to related to problems which are (loosely translated from estonian language - maybe there is better wording in english) - sucked out from the pen and are getting paid by the taxpayer.
I'm pretty sure the title of CEO is also unregulated. You are correct that the term "scientist" is not administered by a regulatory body, in the way "doctor of medicine" and "attorney" would be. You are correct that if we looked into this list of 500 "scientists" that jazz_rule discussed, most of them would not be working actively in climate research and therefore not have anything truly worthwhile to comment upon.
