dithering

In a behavioral context, this word carries a negative connotation of weakness or inefficiency. It describes a state of nervous hesitation where the person is unable to make a decision, often implying that the delay is unnecessary or frustrating to others. It is more informal than "vacillating" and suggests a lack of confidence.

In technical fields like audio engineering and computer graphics, the term is a neutral, descriptive process. It refers to the intentional introduction of noise to mask digital artifacts. Unlike the behavioral sense, technical dithering is a precise tool used to improve perceived quality rather than a sign of indecision.
