Yes, and...
Rule-of-thumb in improvisational comedy / From Wikipedia, the free encyclopedia
"Yes, and...", also referred to as "Yes, and..." thinking, is a rule-of-thumb in improvisational comedy that suggests that an improviser should accept what another improviser has stated ("yes") and then expand on that line of thinking ("and").[1][2][3] The principle does not forbid disagreements between the improvisers' characters, but states that one should not reject the basic premises introduced by the other person, as this would throw them off and harm the flow of the scene.[1]
The principle is also used in business and other organizations for improving the effectiveness of the brainstorming process, fosters effective communication, and encourages the free sharing of ideas.[4]
The ‘Yes, and...’ rule is complemented by the ‘No, but...’ technique, which serves to refine and challenge ideas in a constructive manner.
