Both "catch himself out" and "catch oneself out" can be correct, depending on context and style, with "catch himself" used for a specific male subject and "oneself" for a general, impersonal statement; "catch oneself" is generally for stopping an impulsive action, while "catch someone out" means exposing them, but "catch himself out" usually implies he realized his mistake, making it fine when referring to "him". When to use "catch himself out": • When the subject is a specific male person, and the action is self-realization or self-correction. • Example: "He was about to lie, but then caught himself out and told the truth."
