Citation :Try Undos instead of prompting for confirmation.

Imagine that you just pressed an action button or link. Undos respect the initial human intent by allowing the action to happen smoothly first and foremost. Prompts on the other hand suggest to the user that he or she does not know what they are doing by questioning their intent at all times. I would assume that most of the time human actions are intended and only in small situations are they accidental. The inefficiency and ugliness of prompts is visible when users have to perform actions repeatedly and are prompted numerously over and over - a dehumanizing experience. Consider making your users feel more in control by enabling the ability to undo actions and not asking for confirmation where possible.
