Mentats are humans who possess computer-like logic and computational ability.
The rise of mentats was a response to the ban on thinking machines and conscious robots after the Butlerian Jihad.
Mentats gather and analyze large amounts of data, providing valuable insights and guidance to leaders and decision-makers.
There are varying degrees of mentat ability, and some mentats use sapho juice to enhance their capabilities.
Mentats were primarily used as political advisors by the great houses in the Dune universe.
