Marketers rely too heavily on intuition and past experience rather than data when making decisions, despite data being the most efficient form of information. Only 5% of marketers have statistical knowledge and feel comfortable using data. Some marketers get distracted by minor data fluctuations and make too many adjustments, decreasing efficiency. It is rare and difficult to teach marketers how to filter out noise from data and focus on higher-level goals. Solutions include making marketers more comfortable with uncertainty, promoting the ability to ask strategic questions based on data, and having experienced marketers train and teach others.
