How Science-Based Interviewing Fuels AI Success in Criminal Investigations

Introduction

Interviewing is data collection. In an era where Artificial Intelligence (AI) and machine learning are revolutionizing various sectors, law enforcement is no exception. The integration of body-worn cameras, automatic transcription services, and large language models like GPT-4 are changing the landscape of criminal investigations. However, the

technology is only as good as the data it processes, which brings us to the importance of science-based interviewing (SBI) techniques. Unlike accusatorial methods, science-based interviewing is designed to gather more reliable information, thereby enhancing the quality of investigations in an AI era. This article delves into why science-based interviewing is crucial in the age of AI and how it can significantly aid in fighting crime and understanding crime issues.


What is Artificial Intelligence?

Artificial Intelligence is a field of computer science that aims to create machines capable of intelligent behavior. Within AI, large language models like GPT-4 serve as specialized tools designed to understand, generate, and manipulate human language. These models are built on neural networks and are trained on extensive datasets comprising text from various sources. Their capabilities range from answering questions and summarizing text to generating human-like written content. They can understand context, semantics, and even nuances in language, making them increasingly sophisticated tools for a wide array of applications, including but not limited to Natural Language Processing (NLP).


NLP is another subfield within AI that focuses on the interaction between computers and humans through natural language. The ultimate goal of NLP is to enable computers to understand, interpret, and respond to human language in a meaningful and useful manner. NLP involves several challenges, including language modeling, parsing, sentiment analysis, machine translation, and speech recognition. It is used in various applications that require an understanding of human language, from chatbots and translation services to sentiment analysis and information retrieval systems. In the context of law enforcement and investigations, NLP can analyze large sets of textual data, such as transcriptions of interviews conducted using science-based techniques, to extract relevant information, identify patterns, and assist in decision-making processes. Now what about data input?


Automatic transcription is another AI-driven technology that has significant implications for law enforcement, particularly within the records management section. This technology can convert spoken words, such as those captured by body-worn cameras or recorded during interviews, into written text. Once transcribed, these textual data sets can be integrated into a law enforcement agency's records management system, where they become searchable and analyzable alongside other forms of data like incident reports and witness statements. AI algorithms, especially those specialized in Natural Language Processing (NLP), can then sift through this massive repository of information to identify patterns, correlations, and anomalies that may not be readily apparent to human analysts. For crime analysis and criminal investigations, this means quicker identification of links between cases, more accurate profiling of criminal behavior, and the ability to predict future incidents based on historical data. In essence, the combination of automatic transcription and AI analytics can transform the records management section into a dynamic tool for proactive law enforcement, enhancing both the efficiency and effectiveness of crime analysis and criminal investigations.


SBI and AI

Science-based interviewing, which includes methodologies like the Cognitive Interview, is rooted in empirical research and psychological understanding to elicit more accurate and comprehensive information. The Cognitive Interview, for instance, encourages witnesses to freely recall events without interruption and to mentally recreate the environment in which the event occurred. This is in contrast to accusatorial techniques that often rely on pressure, leading questions, and confrontation. Science-based interviewing employs a variety of techniques, such as active listening, rapport building, evocation, and empathy to create an environment conducive to truthful sharing. By focusing on rapport-building and active listening, this approach minimizes the risk of false confessions and encourages the sharing of nuanced details, thereby providing a richer, more accurate dataset for analysis.


The significance of obtaining truthful and nuanced information is amplified when considering the role of AI and large textual data sets in contemporary investigations. AI algorithms, especially those used in Natural Language Processing (NLP), are highly dependent on the quality of the data they analyze. When these algorithms are fed with high-quality data obtained through science-based interviewing techniques like the Cognitive Interview, they can produce more precise insights, identify patterns, and even make reliable predictions about future behaviors or events. On the flip side, poor-quality data, often the result of accusatorial or non-validated interviewing methods, can lead to incorrect analyses, misguided investigations, and ultimately, miscarriages of justice. Hence, science-based interviewing is a critical foundation for effective AI analysis in law enforcement and criminal investigations.


The Limitations of Accusatorial Interviewing

Accusatorial interviewing, found in all legacy systems, has long been a staple in criminal investigations, but its limitations are becoming increasingly evident, especially in the context of integrating AI and technology into law enforcement practices. Here are some of the key drawbacks:


1. False Confessions - One of the most significant issues with accusatorial interviewing is the risk of eliciting false confessions. The confrontational nature of this approach, which often involves high-pressure tactics, can lead individuals to confess to crimes they did not commit. These false confessions not only jeopardize the integrity of the judicial system but also create a cascade of bad data that can mislead subsequent investigations and analyses.

2. Leading Questions - Accusatorial interviewing often employs leading questions that suggest the answer or contain the information the interviewer is looking to confirm. While this may seem like an effective way to get quick answers, it actually contaminates the data pool. Leading questions can result in confirmatory answers rather than truthful or comprehensive responses, thereby skewing the data that is later used for AI analysis.

3. Accusatorial Questions - Accusatorial questions, which directly or indirectly accuse the interviewee, can create a defensive environment. This defensiveness can lead to incomplete or incorrect answers, further contributing to the pool of bad data. Moreover, accusatorial questions can escalate the emotional state of the interviewee, making it difficult to conduct a rational, fact-based interview.

4. Non-Validated Techniques - Many accusatorial methods involve non-validated techniques that have not been scientifically tested or peer-reviewed. These techniques may include pseudo-scientific methods like "lie detection" based on body language or tone, which have been largely discredited by scientific research. Utilizing such non-validated techniques not only compromises the integrity of the interview but also results in unreliable data.

5. Poor Interviewing Equals Bad Data - The implications of poor interviewing techniques extend far beyond the interview room. In an era where data is king, bad data can have far-reaching consequences. When fed into AI systems for analysis, this flawed information can lead to incorrect conclusions, misguided strategies, and ultimately, ineffective law enforcement practices.

6. The Domino Effect on AI and Investigations - AI systems are designed to identify patterns and make predictions based on the data they are fed. When that data is compromised due to poor interviewing techniques, the AI's output is inherently flawed. This is particularly concerning in predictive policing models or behavioral analysis algorithms that rely on accurate data to function effectively.


Conclusion

In an era where Artificial Intelligence is revolutionizing various sectors, including law enforcement, the importance of science-based interviewing techniques cannot be overstated. As we've explored, these methods, which include the Cognitive Interview, not only yield more accurate and comprehensive data but also serve as the foundation for effective AI analysis. Technologies like automatic transcription and Natural Language Processing are potent tools, but their efficacy is directly tied to the quality of the data they analyze. Therefore, adopting science-based interviewing is not merely an ethical obligation to ensure the integrity of criminal investigations; it's a strategic imperative for any law enforcement agency looking to leverage the full potential of AI. As we move into an increasingly data-driven future, those who fail to integrate science-based interviewing into their practices risk falling irreversibly behind in the rapidly evolving landscape of AI-powered law enforcement.
