> The mentats are theoretically safer because of their imperial conditioning, but even that can be tampered with, as we see with Dr Yueh

Dr Yueh was not a mentat, but a suk doctor who was subject to conditioning. (Which was broken by the Piter de Vries, via the pain amplifiers applied to his wife, Wanna.)

Paul himself was being trained to be a mentat, and there were no hints of conditioning there, neither with Paul, Hawat, or de Vries (albeit he was described as a "twisted mentat", whatever that means).

de Vries was a "twisted mentat" because he was designed by the tleilaxu to be so. I think there were suggestions that Yueh was, too.

That doesn't necessarily mean they were grown in tanks, though, they could just have been "groomed for purpose" in the same way the Tleilaxu's matriarchal counterpart the Bene Gesserit did.

(The Tleilaxu are to me a very obvious stand-in for "patriarchy": there are a few men ruling over a genderless, fluid workforce, and women are literally just birth machines.)

Hey, you're right, I don't think mentats get the conditioning as part of their training. I must have misremembered Thufir having the diamond tattoo.
