The document discusses the benefits of qualitative research over quantitative research. It notes that qualitative research provides a more in-depth understanding of human behavior through smaller, focused samples and investigates why and how people make decisions. An example is provided comparing a quantitative survey of 1,000 customers with a qualitative study that shadowed 15 customers, finding the qualitative research provided more actionable insights. These insights, such as customers' dislike of voicemail, helped improve a company's marketing strategy.
