Which characteristic does NOT describe effective marketing information?

Effective marketing information is crucial for decision-making and strategy development, and one of the key characteristics of such information is that it should be objective rather than subjective. Objectivity ensures that the information is based on measurable data and facts, rather than personal opinions or interpretations, which can lead to biased conclusions. Timeliness is essential, as information must be current to be relevant; cost-effectiveness ensures that the resources spent on gathering information yield valuable insights without excessive expenditure; and information must be actionable, meaning it should provide clear guidance on what steps to take based on the findings. Therefore, the characteristic that does not align with effective marketing information is subjectivity, which compromises the reliability and utility of the data in guiding marketing decisions.
