Frankly, we do give a damn: the relationship between profanity and honesty

There are two conflicting perspectives regarding the relationship between profanity and dishonesty. These two forms of norm-violating behavior share common causes and are often considered to be positively related. On the other hand, however, profanity is often used to express one’s genuine feelings and could therefore be negatively related to dishonesty. In three studies, we explored the relationship between profanity and honesty. We examined profanity and honesty first with profanity behavior and lying on a scale in the lab (Study 1; $N$ = 276), then with a linguistic analysis of real-life social interactions on Facebook (Study 2; $N$ = 73,789), and finally with profanity and integrity indexes for the aggregate level of U.S. states (Study 3; $N$ = 50 states). We found a consistent positive relationship between profanity and honesty; profanity was associated with less lying and deception at the individual level and with higher integrity at the society level

Effects of Expert Testimony and Interrogation Tactics on Perceptions of Confessions

Evidence obtained through the process of interrogation is frequently undermined by what can be perceived as overzealous interrogation tactics. Although the majority of psychologically oriented tactics are legally permissible, they nonetheless contribute to innocent suspects confessing to crimes they did not commit. The present study examined the effect of expert testimony and interrogation tactics on perceptions of a confession. 182 undergraduates read a transcript of a homicide trial that varied based on interrogation tactic: implicit threat of punishment (maximization) or leniency (minimization) and expert witness testimony (presence or absence of expert testimony). Analysis indicated that the type of interrogation tactic used in obtaining the confession affected participants\u27 perceptions of the coerciveness of the interrogation process

A lesson on interrogations from detainees: Predicting self-reported confessions and cooperation

The ability to predict confessions and cooperation from the elements of an interrogation was examined. Incarcerated men (N = 100) completed a 50-item questionnaire about their most recent police interrogation, and regression analyses were performed on self-reported decisions to confess and cooperate. Results showed that the likelihood of an interrogation resulting in a confession was greatest when evidence strength and score on a humanitarian interviewing scale were high, and when the detainee had few previous convictions or did not seek legal advice. We also found that the level of cooperation was greatest when the humanitarian interviewing score was high, and when previous convictions were low. The implications of the findings for interrogation practices are discussed

Encouraging eyewitnesses to falsely corroborate allegations: effects of rapport-building and incriminating evidence

Building rapport involves developing a harmonious relationship with another person and conveying understanding and acceptance towards that person. Law enforcement officers use rapport-building to help gather information from witnesses. But could rapport-building, in some situations, work to contaminate eyewitness testimony? Research shows that compelling incriminating evidence can lead people to corroborate false accusations made against another person. We investigated whether rapport-building – when combined with either Verbal or Verbal+Visual false evidence – might boost these corroboration rates. Subjects took part in a pseudo-gambling task, in which their counterpart was falsely accused of cheating. Using a 2 (Rapport: Rapport vs. No-rapport) × 2 (Incriminating Evidence: Verbal vs. Verbal+Visual) between-subjects design, we persuaded subjects to corroborate the accusation. We found that both rapport and verbal+visual incriminating evidence increased the compliance rate. Even when the incriminating evidence was only presented verbally, rapport-building subjects were almost three times as likely to corroborate a false accusation compared to subjects who did not undergo rapport-building. Our results suggest that although there is widespread and strong support for using rapport-building in interviews, doing so also has the potential to aggravate the contaminating power of suggestive interview techniques

Police interrogation practice in Slovenia

Interrogation techniques are well explored, but in Slovenia it has remained unknown what interrogation techniques are used and what the basic characteristics of suspect interrogations are. The Slovenian interrogation manual proposes some coercive interrogation techniques and neglects their weaknesses. The aim of the current study was to examine Slovenian police officers’ beliefs as to the basic characteristics of their interrogations and whether techniques proposed by the manual are used in practice to begin to provide some insight into what actually happens in such interrogations. A survey instrument was used to obtain selfreport data from a sample of criminal investigators. From 86 completed questionnaires it was found that a typical interrogation of a suspect lasts around 90 minutes and is not recorded. Interviewers typically use three interrogation techniques namely (i) conducting interrogations in isolation; (ii) identifying contradictions in the suspect’s story; and (iii) confronting the suspect with evidence. Findings suggest that some coercive interrogation techniques are used in practice (e.g. offering moral justifications, alluding to have evidence of guilt, good cop/bad cop routine, and minimization). The study is the first insight into the practices of Slovenian investigators when questioning suspects. Differences among general, white-collar and organized crime investigators are also discussed

Interview and interrogation methods and their effects on true and false confessions

The interviewing and interrogation of suspects can be particularly important to securing convictions against the guilty and freeing the wrongly accused. There are two general methods of questioning suspects: information-gathering and accusatorial. The information-gathering approach, used in the United Kingdom, New Zealand, Australia, and elsewhere, as more generally in Western Europe, is characterized by rapport-building, truth-seeking, and active listening. The accusatorial approach, used primarily in the United States and Canada, is characterized by accusation, confrontation, psychological manipulation, and the disallowing of denials. Which method is more effective has become a hotly debated topic as the number of false confessions identified continues to rise. Our objective was to systematically and comprehensively review published and non-published, experimental and observational studies on the effectiveness of interviewing and interrogation methods. We focus on the questioning of suspects using information-gathering and accusatorial methods seeking to elicit confessions

“Supposing that truth is a woman, what then?” The Lie Detector, The Love Machine and the Logic of Fantasy

One of the consequences of the public outcry over the 1929 St Valentine’s Day massacre was the establishment of a Scientific Crime Detection Laboratory at Northwestern University. The photogenic “Lie Detector Man”, Leonarde Keeler, was the Laboratory’s poster boy and his instrument the jewel in the crown of forensic science. The press often depicted Keeler gazing at a female suspect attached to his “sweat box”; a galvanometer electrode in her hand, a sphygmomanometer cuff on her arm and a rubber pneumograph tube strapped across her breasts. Keeler’s fascination with the deceptive charms of the female body was one he shared with his fellow lie detector pioneers, all of whom met their wives – and in William Marston’s case his mistress too – through their engagement with the instrument. Marston employed his own “Love Meter”, as the press dubbed it, to prove that “brunettes react far more violently to amatory stimuli than blondes”. In this paper I draw on the psychoanalytic concepts of fantasy and pleasure to argue that the female body played a pivotal role in establishing the lie detector’s reputation as an infallible and benign mechanical technology of truth
