Geologists remind me of the Bene Gesserit faction in Herbert's Dune, who can identify chemical composition of poison by merely tasting minute quantities. The human body is truly an amazing tool, when trained properly. Another reason why geologists need to be among the ruling elite: it would be near impossible to poison those who can discriminate chemical composition of dirt by merely licking it!

Hah, chemists actually used to use taste to identify many chemicals- but way too many of them died as a result, so they discontinued the practice. Rocks are just a lot safer to lick than chemicals.
