Trust Matters

This chapter explores how to make research trustworthy by focusing on accuracy, consistency, and fairness. Through a courtroom story involving a mistaken arrest, readers learn about the importance of validity (measuring the right thing) and reliability (being consistent). The chapter explains how mistakes in research can be classified as Type I errors (false positives) or Type II errors (false negatives), and how researchers must balance the risks of both. The concept of power – a test's ability to detect true results – is introduced as a way to reduce errors. Students are taught that increasing power can improve accuracy but may be costly. The chapter also highlights objectivity, the need to reduce bias, and key principles in qualitative research such as transferability and dependability, which ensure findings apply to other contexts and remain stable over time. Ultimately, the chapter shows how good research – like good investigation – requires careful, fair, and evidence-based thinking.
