streaks

Streaks refer to consecutive occurrences of a defined event within a sequence of trials or observations. A streak length is the number of successive times the event occurs without an intervening interruption. The defining event can be a success, a specific outcome, or a particular behavior, and the observation window or trial structure varies by context.

In sports and games, streaks are a common metric: a player who scores in several consecutive games, a team that wins multiple matches in a row, or a gamer who logs in daily for a number of days. In habit formation and productivity, daily or weekly streaks are used to track consistency and adherence to routines. In data analysis and quality control, streaks can refer to runs of identical outcomes or measurements, such as a sequence of days with zero defects.

A streak ends when the defined event does not occur on a trial or day, and the count is typically reset according to the convention used. Streaks are sensitive to how the event is defined and to the observation period; different definitions can produce different streak lengths for the same activity.

Streaks can influence motivation and behavior by providing momentum and a sense of achievement. They can also introduce pressure to continue the run or lead to risk-taking when the next outcome is uncertain. Records and visual displays help compare ongoing streaks with historical benchmarks.
