Originating from the practice of using numerical values or figures to gather information, analyze patterns, or make decisions, "by the numbers" encapsulates a disciplined and methodological process. It often involves following an established set of guidelines, rules, or instructions, without deviation or personal judgment. Whether it pertains to a scientific experiment, financial analysis, or even bureaucratic paperwork, this approach seeks to eliminate subjectivity and ambiguity by relying on objective numerical measures.
The phrase is also associated with efficiency and accuracy, as it implies the utilization of predetermined systems or formulas that have been proven effective in achieving a particular result. Consequently, employing a "by the numbers" approach involves a degree of predictability and repeatability, since consistent outcomes are expected when the same steps or principles are applied.
Furthermore, "by the numbers" can also connote a lack of creativity or originality, as it suggests a rigid adherence to a preexisting set of rules or conventions. It may therefore carry connotations of monotony or mechanical execution, implying that the task at hand is being carried out without much individuality or innovation.
