When Comfortable Methods Become Dangerous Habits: How Investigative Experience Can Compromise Statement Reliability

Zenodo Description — Copy and Paste:

Experience is one of an investigator's most valuable assets, but familiar interviewing methods can become dangerous habits when repetition is mistaken for reliability.

This professional article examines how cognitive schemas, confirmation bias, misplaced confidence, and resistance to new evidence can influence investigative interviewing practices and compromise statement reliability.

Drawing on principles from cognitive psychology and evidence-based investigative interviewing, the article explores how investigator expectations, leading questions, and established routines can affect information gathering. It emphasizes the importance of critically evaluating familiar methods, distinguishing observations from interpretations, and testing statements against independently established evidence.

The central principle is straightforward: Repetition makes a method familiar. It doesn't make it reliable.
