Abstract

When it is necessary to evaluate the false attitude, such as lying, in a forensic examination, the professionals who carry out this type of work have limited resources to which they can resort. One of the reasons is the small investment in research in the area of ​​lie evaluation. Still on this point, evaluating the lie is an extremely complex task, with several views that one may have to carry out such action. One possible way to observe false attitudes is to analyze the presence of malinger attitudes. However, psychometric assessment tools for this area are also scarce and not very scientifically elegant. Finally, and most importantly, there is a lack of investigation where the samples are entirely forensic. The present work presents a description of a forensic sample (n = 470) regarding the type of malinger attitude present and its sociodemographic characteristics. There are some points of interest in some types of social characteristics such as the type of academic qualification or the type of profession. The type of legal process to which the subjects being assessed seem to be important to consider and finally there is a correlation of about 13% in which the subjects' intelligence explains their malinger attitude. Further studies are needed. The data presented in this work are of interest to professionals in the specialty, but above all, they are believed as a step towards having a line of comparison for scientific investment in the future in this area of ​​forensic evaluation.
