Lying about money and game points by men and women and its relation to the Self-Reported Lying Scale

Introduction

The present study was designed to examine the effect of monetary and non-monetary endowment on lying by men and women in the Ultimatum Game. Another goal was to examine to what extent the Self-Reported Lying Scale (SRLS), described here for the first time, predicts lying in the Ultimatum Game.

Methods

Examinees (162, 82 women) were allocated to four experimental conditions in a 2 × 2 factorial design. Two endowment conditions (money and game points) were crossed with two sex conditions (men and women). Participants underwent an Ultimatum Game in which they were permitted to conceal part of the endowment from an unidentified partner. Finally, participants completed the SRLS.

Results

The results indicated that more cash than points were concealed from the partner, and men concealed more of their endowment than women. We further defined fake fairness in sharing that combined hiding a more significant portion of the endowment from the partner while presenting fair sharing of the remaining award. We found more fake fairness when money was shared than when points were concealed. Fake fairness is more significant for men than for women. For money and points alike, concealment was predicted by the global score of the SRLS and its five subscales (self-assessed lying ability, lie detection ability, the use of reason in lying, lie acceptability, and lie frequency).

Discussion

It was suggested that a monetary endowment is more sensitive to lying than game points and involves more fake fairness. Nevertheless, the differences are quantitative, and the same response pattern exists in the two endowment conditions. Replacing money with points is a proper solution whenever a monetary endowment presents difficulties. It was further suggested that sex differences exist in lying using an asymmetric information UG, where proposers were permitted to mislead responders about their endowment. Finally, the SRLS may contribute to a better understanding of the question of who lies.

Individual differences in self-reported lie detection abilities

Previous literature on lie detection abilities bears an interesting paradox. On the group level, people detect others' lies at guessing level. However, when asked to evaluate their own abilities, people report being able to detect lies (i.e., self-reported lie detection). Understanding this paradox is important because decisions which rely on credibility assessment and deception detection can have serious implications (e.g., trust in others, legal issues). In two online studies, we tested whether individual differences account for variance in self-reported lie detection abilities. We assessed personality traits (Big-Six personality traits, Dark Triad), empathy, emotional intelligence, cultural values, trust level, social desirability, and belief in one's own lie detection abilities. In both studies, mean self-reported lie detection abilities were above chance level. Then, lower out-group trust and higher social desirability levels predicted higher self-reported lie detection abilities. These results suggest that social trust and norms shape our beliefs about our own lie detection abilities.

Effects of Mood on Psychophysiological Detection of Concealed Information and the Relation to Self-Assessed Lying Ability

The present study examined the effects of mood on physiological responses in the Concealed Information polygraph Test and the relation to self-assessed lying ability. One hundred and eight undergraduate students self-assessed their lie-telling ability, committed a mock theft, and were asked to conceal information related to the crime. Participants were then divided into three equal groups: two groups were asked to provide a detailed written account of either a happy or sad event in order to induce a happy or sad mood, while the third group served as a neutral group. Participants then underwent a polygraph test and were asked to try to avoid detection. An induced happy or sad mood tended to lower relative skin conductance responses to critical (crime related) items and enhance relative cardiovascular responses. Relative respiration responses to critical items obtained for the sad mood condition were more robust than the ones obtained for the happy mood condition. Under induced sad and happy moods, those who self-rated their lie-telling ability as high showed enhanced cardiovascular responsivity to critical items. These results were limited to the initial phase of the test. We discussed possible motivational explanations and implications for the Concealed Information polygraph test.

Face-to-Face Lying: Gender and Motivation to Deceive

Two studies examined gender differences in lying when the truth-telling bias prevailed (study 1) and when inspiring lying and disbelief (study 2). The first study used 156 community participants (91 women) in pairs. First, participants completed the Narcissistic Personality Inventory, the Lie- and Truth Ability Assessment Scale (LTAAS), and the Rational-Experiential Inventory. Then, they participated in a deception game where they performed as senders and receivers of true and false communications. Their goal was to retain as many points as possible according to a payoff matrix that specified the reward they would gain for any possible outcome. Results indicated that men lied more and were more successful lie-tellers than women. In addition, men believed the sender less than women but were not more successful detectors of lies and truths. Higher perceived lie-telling ability, narcissistic features, and experiential thinking style explained men's performance. The second study used 100 volunteers (40 women) who underwent the same procedure. However, the payoff matrix encouraged lying and disbelieving. Results showed again that men lied more than women. As to performance, men were more successful lie detectors than women, but there was no truth detection difference. Women did not differ in their success in telling and detecting lies and truths. The inconsistent gender differences in production and detection lies and truths dictate caution in interpreting them.

Exploring the consequences of knowledge hiding: an agency theory perspective

Purpose

The purpose of the study is to explore empirically the consequences of knowledge hiding at the individual level and from the knowledge hiding committers' perspective. Hence, in line with agency theory and prior literature on knowledge hiding, the study investigates the associations between different facets of knowledge hiding and individual-level job performance, as well as the mediating role of employee well-being in the associations.

Design/methodology/approach

Structural equation modeling was used to analyze multisource survey data from a sample of 214 employees and 34 immediate supervisors, in a professional services company in Finland.

Findings

Evasive hiding was found to be negatively associated with in-role job performance and positively associated with innovative job performance. Playing dumb was found to be positively associated with in-role job performance. Finally, even though the association between rationalized hiding and innovative job performance was found to be positive, it was found to be of a smaller magnitude when employee well-being was taken into account.

Practical implications

Forceful unhealthy competition and exploitative and workaholic cultures are discussed to reduce knowledge hiding behavior among employees and their negative consequences.

Originality/value

The study highlights the paradox of managing organizational knowledge. In line with agency theory, we advocate that while knowledge sharing is one of the major assets of organizational welfare from the organizational perspective, it may resonate with the employee's perspective. Consequently, unless employees' self-interest and organizational interests are aligned, the paradox of managing organizational knowledge arises, and the classic agency problem occurs.

Frequent Countermeasure Usage by Narcissistic Examinees in the Concealed Information Test

Narcissistic dimensions and self-assessed lie and truth-telling and detecting abilities were used to predict deliberate attempts to influence the outcomes of the Concealed Information polygraph Test. In this study, which used a fabricated murder scenario, 241 examinees were randomly allocated to four experimental conditions in a 2 × 2 factorial design. Two guilt conditions (guilty and innocent) were crossed with two countermeasures conditions (with or without countermeasure instructions). One group consisted of 120 informed guilty participants who were offered the opportunity to give a false response to neutral items by verbally answering "yes," by which they falsely confirmed that the item is relevant to the murder case. Participants were told that frequent lying would confuse the polygraph and help them pass the test. Another informed guilty group (41 participants) was not given the opportunity to use countermeasures. Two control groups of 40 participants each were unaware of the critical items. One control group used countermeasures while the other did not. Narcissistic dimensions and self-assessed lie-telling ability correlated positively with frequent use of countermeasures. Conflicting results about the relation between countermeasure usage and physiological responses to critical items were obtained.

Interviewing Suspects with Avatars: Avatars Are More Effective When Perceived as Human

It has been consistently demonstrated that deceivers generally can be discriminated from truth tellers by monitoring an increase in their physiological response. But is this still the case when deceivers interact with a virtual avatar? The present research investigated whether the mere “belief” that the virtual avatar is computer or human operated forms a crucial factor for eliciting physiological cues to deception. Participants were interviewed about a transgression they had been seduced to commit, by a human-like virtual avatar. In a between-subject design, participants either deceived or told the truth about this transgression. During the interviews, we measured the physiological responses assessing participants' electrodermal activity (EDA). In line with our hypothesis, EDA differences between deceivers and truth tellers only were significant for participants who believed they interacted with a human operated (compared to a computer operated) avatar. These results have theoretical as well as practical implications which we will discuss.

Personality Correlates of the Self-Assessed Abilities to Tell and Detect Lies, Tell Truths, and Believe Others

The contribution of personality dimensions (the Big Five) to self-assessed communication abilities to tell and detect lies, tell truths, and believe others was examined. One hundred seventy-four undergraduate students completed the Big Five personality inventory (BFI) and evaluated their relative lie-telling, truth-telling, lie-detection and their ability to believe other peoples’ truths. Results indicated that Extraversion predicted enhanced lie-telling, truth-telling, and lie-detection abilities. Openness to experience predicted higher ratings of lie-telling and lie-detecting abilities, indicating that for curious people with intellectual skills and attentiveness to inner feelings, lie-related abilities are important. Agreeableness predicted high ratings of believing skills and low ratings of the remaining three skills, indicating that well-tempered people tend to believe others. Conscientiousness and Neuroticism were negatively associated with telling lies persuasively. This was explained by the need of conscientious people to be honest and by the low self-confidence and negative emotions of people who scored high on Neuroticism. Implications of the present results were discussed.

An Investigation of Self-Assessment Bias in Mental Health Providers

Previous research has consistently found self-assessment bias (an overly positive assessment of personal performance) to be present in a wide variety of work situations. The present investigation extended this area of research with a multi-disciplinary sample of mental health professionals. Respondents were asked to: (a) compare their own overall clinical skills and performance to others in their profession, and (b) indicate the percentage of their clients who improved, remained the same, or deteriorated as a result of treatment with them. Results indicated that 25% of mental health professionals viewed their skill to be at the 90th percentile when compared to their peers, and none viewed themselves as below average. Further, when compared to the published literature, clinicians tended to overestimate their rates of client improvement and underestimate their rates of client deterioration. The implications of this self-assessment bias for improvement of psychotherapy outcomes are discussed.

Lie-detection biases among male police interrogators, prisoners, and laypersons

Beliefs of 28 male police interrogators, 30 male prisoners, and 30 male laypersons about their skill in detecting lies and truths told by others, and in telling lies and truths convincingly themselves, were compared. As predicted, police interrogators overestimated their lie-detection skills. In fact, they were affected by stereotypical beliefs about verbal and nonverbal cues to deception. Prisoners were similarly affected by stereotypical misconceptions about deceptive behaviors but were able to identify that lying is related to pupil dilation. They assessed their lie-detection skill as similar to that of laypersons, but less than that of police interrogators. In contrast to interrogators, prisoners tended to rate lower their lie-telling skill than did the other groups. Results were explained in terms of anchoring and self-assessment bias. Practical aspects of the results for criminal interrogation were discussed.

Police lie detection accuracy: the effect of lie scenario

Although most people are not better than chance in detecting deception, some groups of police professionals have demonstrated significant lie detection accuracy. One reason for this difference may be that the types of lies police are asked to judge in scientific experiments often do not represent the types of lies they see in their profession. Across 23 studies, involving 31 different police groups in eight countries, police officers tested with lie detection scenarios using high stakes lies (i.e., the lie was personally involving and/or resulted in substantial rewards or punishments for the liar) were significantly more accurate than law enforcement officials tested with low stakes lies. Face validity and construct validity of various lie scenarios are differentiated.

Improving decision making in forensic child sexual abuse evaluations

Mental health professionals can assist legal decision makers in cases of allegations of child sexual abuse by collecting data using forensic interviews, psychological testing, and record reviews, and by summarizing relevant findings from social science research. Significant controversy surrounds another key task performed by mental health professionals in most child sexual abuse evaluations, i.e., deciding whether or not to substantiate unconfirmed abuse allegations. The available evidence indicates that, on the whole, these substantiation decisions currently lack adequate psychometric reliability and validity: an analysis of empirical research findings leads to the conclusion that at least 24% of all of these decisions are either false positive or false negative errors. Surprisingly, a reanalysis of existing research also indicates that it may be possible to develop reliable, objective procedures to improve the consistency and quality of decision making in this domain. A preliminary, empirically-grounded procedure for making substantiation decisions is proposed.

The Psychology of Confessions: A Review of the Literature and Issues

Recently, in a number of high-profile cases, defendants who were prosecuted, convicted, and sentenced on the basis of false confessions have been exonerated through DNA evidence. As a historical matter, confession has played a prominent role in religion, in psychotherapy, and in criminal law-where it is a prosecutor's most potent weapon. In recent years, psychologists from the clinical, personality, developmental, cognitive, and social areas have brought their theories and research methods to bear on an analysis of confession evidence, how it is obtained, and what impact it has on judges, juries, and other people. Drawing on individual case studies, archival reports, correlational studies, and laboratory and field experiments, this monograph scrutinizes a sequence of events during which confessions may be obtained from criminal suspects and used as evidence. First, we examine the preinterrogation interview, a process by which police target potential suspects for interrogation by making demeanor-based judgments of whether they are being truthful. Consistent with the literature showing that people are poor lie detectors, research suggests that trained and experienced police investigators are prone to see deception at this stage and to make false-positive errors, disbelieving people who are innocent, with a great deal of confidence. Second, we examine the Miranda warning and waiver, a process by which police apprise suspects of their constitutional rights to silence and to counsel. This important procedural safeguard is in place to protect the accused, but researchers have identified reasons why it may have little impact. One reason is that some suspects do not have the capacity to understand and apply these rights. Another is that police have developed methods of obtaining waivers. Indeed, innocent people in particular tend to waive their rights, naively believing that they have nothing to fear or hide and that their innocence will set them free. Third, we examine the modern police interrogation, a guilt-presumptive process of social influence during which trained police use strong, psychologically oriented techniques involving isolation, confrontation, and minimization of blame to elicit confessions. Fourth, we examine the confession itself, discussing theoretical perspectives and research on why people confess during interrogation. In particular, we focus on the problem of false confessions and their corrupting influence in cases of wrongful convictions. We distinguish among voluntary, compliant, and internalized false confessions. We describe personal risk factors for susceptibility to false confessions, such as dispositional tendencies toward compliance and suggestibility, youth, mental retardation, and psychopathology. We then examine situational factors related to the processes of interrogation and show that three common interrogation tactics-isolation; the presentation of false incriminating evidence; and minimization, which implies leniency will follow-can substantially increase the risk that ordinary people will confess to crimes they did not commit, sometimes internalizing the belief in their own culpability. Fifth, we examine the consequences of confession evidence as evaluated by police and prosecutors, followed by judges and juries in court. Research shows that confession evidence is inherently prejudicial, that juries are influenced by confessions despite evidence of coercion and despite a lack of corroboration, and that the assumption that "I'd know a false confession if I saw one" is an unsubstantiated myth. Finally, we address the role of psychologists as expert witnesses and suggest a number of possible safeguards. In particular, we argue that there is a need to reform interrogation practices that increase the risk of false confessions and recommend a policy of mandatory videotaping of all interviews and interrogations.
