Answer:
When we rationalize to justify our past actions, and ignore competing claims, we can get caught up in holding two contradictory views while believing both to be true. This is referred to as doublethink.
Step-by-step explanation:
The term Doublethink was defined by author George Orwell as "a deliberate or unconscious acceptance or promulgation of conflicting facts, principles, etc." Basically, it means to accept as correct two opposite and mutually contradictory beliefs. For the author, double thinking was a system used by humans in order to "mentally cheat" and to avoid having to have accountability over past actions or ideas held.
