CORE DEFINITION

Mark Twain's classic case: the pastor's speech was too long, and the audience went from initially 'wanting to donate' to 'somewhat impatient', and finally to 'deciding not to donate and even wanting to steal some money'. It refers to the psychological phenomenon where excessive, intense, or prolonged stimulation causes extreme impatience or psychological reactance. - Scaffolding role: the art of restraint. - Whether criticizing children, promoting products, or advertising, knowing when to stop is the highest state. Once the audience's psychological threshold is exceeded, the effect not only returns to zero but also turns negative. In this era of scarce attention, verbosity is a crime.
