trial balloon

The phrase "trial balloon" refers to a tentative measure or idea that is floated or proposed to test public opinion or gauge the reaction of a particular group before taking further action or implementing it more formally. It is often used in the political or business context to refer to a deliberate strategy of introducing an idea in a less binding or formal manner to elicit feedback and assess its potential success or acceptance. The purpose of a trial balloon is to gather information, assess risks, and make more informed decisions based on the response received.
