Newspeak word, and one of the central pillars of Ingsoc. Crimestop refers to the ability to stop short of any thought that might be heretical or unorthodox before it is even thought, as if by instinct. It is the ability to misunderstand analogies, fail to perceive logical errors, and be repelled or bored by any train of thought or conversation that might be inimical to Ingsoc. Of course, this process is not unique to Ingsoc, and has been and still is applied by most religious and political extremists.

Crimestop is not stupidity, or at least not natural stupidity. It is the ability to deliberately retard one's own intelligence, and, of course, to forget the process of doing it by doublethink.

From STEM, an abbreviation short for "Science, Technology, Engineering and Mathematics", a STEMlord is a pejorative term for a particular kind of person who has studied in these areas at university or works in these fields who holds a pretentious, condescending attitude to anyone who has studied in any other fields, particularly the Arts and Humanities. They typically believe themselves to be more "intelligent" and "rational", while generally remaining incredibly ignorant outside of their areas of expertise and having the charisma of a rotting pig's backside.
