Manipulating information to create doubt

Gaslighting is a term for when a person purposefully confuses someone by giving them false information in order to create doubt in their own memory.

The term comes from "Gas Light," a 1938 stage play where a husband tries to convince his wife that she is insane by changing small features in their environment. Gaslighting may involve giving people false information and/or moving objects that they will notice in order to convince them that they are losing their mind.
