My, my, but you underestimate Cardassian mental discipline, don't you, DevilEyes?

These people are capable of resisting mind-melds, not being read by telepaths, have eidetic memories--need I go on?
Also, I might add something interesting to think about, when it comes to the Cardassians' abilities as spies. They are remarkably successful at it--and considering that their hearing is quantitatively inferior to other species, to include humanity, this is an even cooler achievement. (Personally, I like to think that they don't artificially enhance their hearing--that it's all in the technique.
