Abstract

In judicial practice, one of the fundamental objectives is to investigate the sincerity of persons suspected of committing acts provided for by criminal law, as well as of those who possess information or knowledge relevant to elucidating the circumstances of an act. Establishing the truth is essential not only for finding guilt or innocence, but also for ensuring a fair trial and the correct substantiation of acts of justice. Truth thus constitutes a central pillar of the criminal process, and any method that contributes to its identification must be used with responsibility and rigor.

In this context, the polygraph technique has acquired an important role as a complementary tool in the investigation of crimes. The polygraph, by monitoring the physiological parameters of the subject during the interview, can provide useful clues regarding the veracity of the statements, supporting the judicial investigation. However, the efficiency of this method depends largely on compliance with standardized procedures, the operator's training and the correct understanding of its limits.

The application of the polygraph is not an autonomous solution and cannot substitute other investigative methods, but functions as an auxiliary tool that complements traditional evidence. At the same time, the success of its use requires a thorough knowledge of the psychological and forensic paradigms involved, as well as a critical evaluation of the results obtained. Only by combining technical expertise with ethical and legal principles can the polygraph effectively contribute to identifying the truth and strengthening the act of justice.
