Deep Deception: The story of the spycop network, by the women who uncovered the shocking truth

Product Information

These men were undercover police officers, who had targeted the women for their links to activist groups. They took the identities of dead children and carried fake passports and driving licences. They were all married, some with children. They had been working from a set of guidelines and were all using the same manipulative techniques. k) Naturality was exploited by hesitation and speaking rate, but not much was reported as the contribution of this sort of cue; However, the datasets and experiment setups are too diverse to be compared. Therefore, a direct benchmark of the studies’ performances is not reasonable. We include them here as another feature of those studies, but we do not claim that the specific research that achieved a higher accuracy than other is better. Those performance measures do not work here as a scale of success when approaching the problem, nor do they indicate that a particular approach is better than other. They can work, at best, as a baseline for further research designed under the same conditions. Superior lie-catchers seem to acquire their ability from a personal desire to perform better on their job, no matter what it is [ 5]. It is like any other professional skill or talent, improved through effort, dedication, personal interest, technical knowledge, and training. Thus, such highly skilled lie-catchers result from intense dedication, which is a motivating factor for further research on deception detection. It is reasonable to believe that those levels of accuracy can be approximated or even replicated by a Machine Learning classifier given the correct cues are processed and interpreted.

f) While the theory on deception detection strongly relates it to the subject’s emotional state, most studies did not approach the problem under this perspective, rather modeling the features from behavioral changes; a) What are the best performing Machine Learning techniques applied to automatic deception detection? The Machine Learning techniques that best performed were Decision Trees, Gradient Boosting, Neural Networks, Multi-view learning, Random Forest, and Support Vector Machines (SVM).Singh A, Thakur N, Sharma A. A review of supervised machine learning algorithms. Proc 10th INDIACom; 2016 3rd Int Conf Comput Sustain Glob Dev INDIACom 2016. 2016;1310–5. Psychological traits are important because some specific, not-so-usual ones can influence how a deceiver behaves while telling lies. The expected behavioral shifts may not happen in individuals that show these traits. However, most studies do not delve deeply into this feature. Statistical details can be found in section 4.7 (Remaining features analysis) in S6 File (Statistical Analysis Notebook).

There are several Machine Learning algorithms based on different theoretical frameworks and strategies [ 19], such as Decision Trees [ 28], Naïve Bayes [ 29], Support Vector Machines [ 30], K-Means [ 31], Random Forests [ 32] and Neural Networks [ 33].Our goal is to present an abstract notion of the state of each of those dimensions so we could give researchers an insight about each theme. We hope that the following sections will help further studies to direct their effort to fill in the still existing gaps. We report what we have found and discuss it in comparison to deception detection theories, primarily to highlight research opportunities. October 2023 9:00 ~ Senior IT Officer; Head of Sexual Violence Helpline; Senior Counsellors – Women & Girls Network – London (& 3 November 2023) One paper reports correlations between Extraversion and Conscientiousness, and the ability to deceive, but does not relate it to Machiavellianism. Still, we consider NEO-FFI as a promising set of features for deception detection. It has severely affected our ability to trust other people, or to form intimate relationships again. You can’t compensate for that,” she says, noting that even the state compensation system does not see the world from a woman’s perspective, being more inclined to focus on loss of earnings. Ball TJ.

Deep Dark Deception - Rotten Tomatoes 2007: Deep Dark Deception - Rotten Tomatoes

Conventional Machine Learning methods are severely impacted by the features they consume. Wrong features may lead to incorrect or undesired results, which promotes an entire area of study known as feature engineering. However, Deep Learning methods can detect which features are relevant in raw data and extract them instead of others [ 20]. Deception detection is the act of deciding whether a certain communication carries the truth or not. It is an active and evidence-driven inference process [ 14]. High-stakes deceptions are believed to induce behavioral and physiological changes in the deceiver, yielding more evident indicators of lie-telling [ 1]. The task even more challenging because no clue alone is an indisputable predictor of deception [ 2, 4, 15]. Certain people represent an exception to the emotional effects when they are deceiving. Machiavellian people usually look their accuser right in the eye when they are falsely denying something, which contradicts the notion of eye aversion [ 4, 15]. Thus, the deceiver’s psychological profile may influence their behavior and, consequently, over the cues they give away.

Limitations and further work

Regarding linguistic cues, one article presents a comprehensive study comparing five languages from different parts of the world [ 51]. Structural differences demonstrate the need for specific approaches for each language or, at least, a group of similar languages. Therefore, this paper is not about Artificial Intelligence, Machine Learning, or deception detection. Instead, it is a literature review on deception detection with Machine Learning. Our intention is not to go deep into either deception detection or Machine Learning. Instead, our focus is on selecting and scrutinizing research papers on the application of Machine Learning for deception detection. Complexity and performance are important because the processing power computers offer nowadays allows researchers to invest in more sophisticated and processor-demanding approaches. Some methods that run on a personal computer today were out of possibility 20 years ago.

I met with Helen and over the following few months she introduced me to seven other women who had similarly been deceived into long term sexual relationships with undercover police officers. It was now clear that the rogue officer story was far from unique and indeed appeared to reflect a pattern. Lying is a frequent and pervasive social phenomenon [ 3]. While some forms may be accepted as a “social lubricant” [ 4], others are socially harmful. Telling (and being told) lies is frequent but perceiving them is a major challenge for most people. The average person has a lie detection rate around 54% [ 5, 6], rarely reaching 60%, and sometimes falling below 50% [ 7].Moreover, situational and idiosyncratic factors can affect the subjects’ behavior and, therefore, which cues are leaked when deceiving. Such cues are more specific and challenging to detect [ 4]. Not considering these factors can decrease the detection accuracy—a situation referred to as the Brokaw hazard [ 2].

It’s clear that Mary’s is not a historical case. Often, our concerns about abusive covert policing practices are dismissed as a thing of the past. We’re told that cases from the 1970s and 80s, as evidenced in the undercover policing inquiry, happened in another era when attitudes were different, and policing didn’t have the rigorous oversight and management it does now. According to the report, however, Mary discovered the cover-up in 2020. Deception is said to be related to three different emotions: guilt, fear, and delight [ 2]. A deceiver may feel guilty because his/her conscience tells him/her that deceiving is morally wrong. Fear comes when a deceiver is afraid of being caught and having to account for his/her deception, eventually feeling ashamed or humiliated when exposed. However, a deceiver can feel delighted when the act of deceiving leads to the joy of fooling others [ 4].
