Together with Ronald Poppe, Paul Taylor, and Gordon Wright, Sophie van der Zee (previously employed at the Cambridge Computer Laboratory), took a plunge and tested their automated lie detection methods in the real world. How well do the lie detection methods that we develop and test under very controlled circumstances in the lab, perform in the real world? And what happens to you and your social environment when you constantly feel monitored and attempt to live a truthful life? Is living a truthful life actually something we should desire?

Whodunnit? Fascinating Forensics by BBC’s Naked Scientists
BBC’s Naked Scientists recently did an hour-long show with live audience about forensic science, during which they solved a (fictitious) murder with the help of six forensic scientists and practitioners.
Chris Smith and Ginny Smith covered the forensic process from crime scene to court room and discussed all the evidence in between, including how to retrieve forensic evidence from a crime scene, digital forensics and the (lack of) randomness of numbers, toxicology, pathology, eye-witness testimony and our work on motion-based lie detection.

Decepticon: International Conference on Deceptive Behavior
Call for papers
We are proud to present DECEPTICON 2015 – International Conference on Deceptive Behavior, to be held 24-26 August 2015 at the University of Cambridge, UK. Decepticon brings together researchers, practitioners, and like-minded individuals with a taste for interdisciplinary science in the detection and prevention of deception.
We are organising two panel sessions; one on Future Directions in Lie Detection Research with Aldert Vrij, Par-Anders Granhag, Steven Porter and Timothy Levine, and one on Technology Assisted Lie Detection with Jeff Hancock, Judee Burgoon, Bruno Verschuere and Giorgio Ganis. We broadly and warmly welcome people with varying scientific backgrounds. To cover the diversity of approaches to deception research, our scientific committee members are experts in fields from psychology to computer science, and from philosophy to behavioral economics. For example, scientific committee members from the University of Cambridge are Ross Anderson, Nicholas Humphrey, Peter Robinson and Sophie Van Der Zee.
We strongly encourage practitioners, academics and students alike to submit abstracts that touch on the topic of deception. The extended deadline for abstract submissions (max. 300 words) for an oral, panel or poster presentation is 8 APRIL 2015. Interested in attending, but don’t feel like presenting? You can register for the conference here.

Media coverage “to freeze or not to freeze” paper
On the 5th of January this year we presented a paper on the automatic detection of deception based on full-body movements at HICSS (Hawaii), which we blogged about here at LBT. We measured the movements of truth tellers and liars using full-body motion capture suits and found that liars move more than truth tellers; when combined with interviewing techniques designed to increase the cognitive load of liars, but not of truth tellers, liars even moved almost twice as much as truth tellers. These results indicate that absolute movement, when measured automatically, may potentially be a reliable cue to deceit. We are now aiming to find out if this increase in body movements when lying is stable across situations and people. Simultaneously, we are developing two lines of technology that will make this method more usable in practice. First, we are building software to analyse behaviors in real-time. This will enable us to analyse behavior whilst it is happening (i.e., during the interview), instead of afterwards. Second, we are investigating remote ways to analyse behavior, so interviewees will not have to wear a body-suit when being interviewed. We will keep you updated on new developments.
In the meantime, we received quite a lot of national and international media attention. Here is some tv and radio coverage on our work by Dailymotion, Fox (US), BBC world radio, Zoomin TV (NL), WNL Vandaag de dag (NL, deel 2, starts at 5:20min), RTL Boulevard (NL), Radio 2 (NL), BNR (NL), Radio 538 (NL). Our work was also covered by newspapers, websites and blogs, including the Guardian, the Register, the Telegraph, the Telegraph incl. polygraph, the Daily Mail, Mail Online, Cambridge News, King’s College Cambridge, Lancaster University, Security Lancaster, Bruce Schneier’s blog, International Business Times, RT, PC World, PC Advisor, Engadget, News Nation, Techie News, ABP Live, TweakTown, Computer World, MyScience, King World News, La Celosia (Spanish),de Morgen (BE), NRC (NL), Algemeen Dagblad (NL), de Volkskrant (NL), KIJK (NL), and RTV Utrecht (NL).
Technology assisted deception detection (HICSS symposium)
The annual symposium “Credibility Assessment and Information Quality in Government and Business” was this year held on the 5th and 6th of January as part of the “Hawaii International Conference on System Sciences” (HICSS). The symposium on technology assisted deception detection was organised by Matthew Jensen, Thomas Meservy, Judee Burgoon and Jay Nunamaker. During this symposium, we presented our paper “to freeze or not to freeze” that was posted on this blog last week, together with a second paper on “mining bodily cues to deception” by Dr. Ronald Poppe. The talks were of very high quality and researchers described a wide variety of techniques and methods to detect deceit, including mouse clicks to detect online fraud, language use on social media and in fraudulent academic papers and the very impressive avatar that can screen passengers when going through airport border control. I have summarized the presentations for you; enjoy!

Introduction Symposium by Judee Burgoon
This symposium is being organized annually during the HICSS conference and functions as a platform for presenting research on the use of technology to detect deceit. Burgoon started off describing the different types of research conducted within the Center for the Management of Information (CMI) that she directs, and within the National Center for Border Security and Immigration. Within these centers, members aim to detect deception on a multi-modal scale using different types of technology and sensors. Their deception research includes physiological measures such as respiration and heart rate, kinetics (i.e., bodily movement), eye-movements such as pupil dilation, saccades, fixation, gaze and blinking, and research on timing, which is of particular interest for online deception. Burgoon’s team is currently working on the development of an Avatar (DHS sponsored): a system with different types of sensors that work together for screening purposes (e.g., border control; see abstracts below for more information). The Avatar is currently been tested at Reagan Airport. Sensors include a force platform, Kinect, HD and thermo cameras, oculometric cameras for eye-tracking, and a microphone for Natural Language Processing (NLP) purposes. Burgoon works together with the European border management organization Frontex. Continue reading Technology assisted deception detection (HICSS symposium)
First Global Deception Conference
Global Deception conference, Oxford, 17–19th of July 2014
This deception conference, as part of Hostility and Violence, was organized by interdisciplinary net. Interdisciplinary net runs about 75 conferences a year and was set up by Rob Fisher in 1999 to facilitate international dialogue between disciplines. Conferences are organized on a range of topics, such as gaming, empathy, cyber cultures, violence and communication and conflict. Not just the topics of the different conferences are interdisciplinary, this is the case within each conference as well. During our deception conference we approached deception from very different angles; from optical illusions in art and architecture via literary hoaxes, fiction and spy novels to the role of the media in creating false beliefs amongst society and ending with a more experimental approach to detecting deception. Even a magic trick was part of the (informal) program, and somehow I ended up being the magician’s assistant. You can find my notes and abstracts below.
Finally, if you (also) have an interest in more experimental deception research with a high practical applicability, then we have good news. Aldert Vrij, Ross Anderson and I are hosting a deception conference to bring together deception researchers and law enforcement people from all over the world. This event will take place at Cambridge University on August 22-24, 2015.
Session 1 – Hoaxes
John Laurence Busch: Deceit without, deceit within: The British Government behavior in the secret race to claim steam-powered superiority at sea. Lord Liverpool became prime minister in 1812 and wanted to catch up with the Americans regarding steam-powered boats. The problem however was that the Royal Navy did not know how to build those vessels, so they joined the British Post in 1820 who wanted to build steam powered boats to deliver post to Ireland more quickly. The post was glad the navy wants to collaborate, although the navy was deceptive; they kept quiet, both to the post, the public and other countries, that they did not know how to build those vessels, and that were hoping to learn how to build a steam boat from them, which succeeded, importantly whilst successfully masking/hiding from the French and the Americans that the British Navy was working on steam vessels to catch up with the US. So the Navy was hiding something questionable (military activity) behind something innocent (post); deceptive public face.
Catelijne Coopmans & Brian Rappert: Revealing deception and its discontents: Scrutinizing belief and skepticism about the moon landing. The moon landing in the 60s is a possible deceptive situation in which the stakes are high and is of high symbolic value. A 2001 documentary by Fox “Conspiracy theory: Did we land on the moon or not?” The documentary bases their suspicions mainly on photographic and visual evidence, such as showing shadows where they shouldn’t be, a “c” shape on a stone, a flag moving in a breeze and pictures with exactly the same background but with different foregrounds. As a response, several people have explained these inconsistencies (e.g., the C was a hair). The current authors focus more on the paradoxes that surround and maybe even fuel these conspiracy theories, such as disclosure vs. non-disclosure, secrecy that fuels suspicion. Like the US governments secrecy around Area 51. Can you trust and at the same time not trust the visual proof of the moan landing presented by NASA? Although the quality of the pictures was really bad, the framing was really well done. Apollo 11 tried to debunk this conspiracy theory by showing a picture of the flag currently still standing on the moon. But then, that could be photoshopped…
Discussion: How can you trust a visual image, especially when used to proof something, when we live in a world where technology makes it possible to fake anything with a high standard? Continue reading First Global Deception Conference
European Association of Psychology and Law Conference 2014
The European Association of Psychology and Law (EAPL) annually organises a conference to bring together researchers and practitioners operating in a forensic context. Combining different disciplines, such as psychology, criminology and law leads to a multidisciplinary conference with presentations on topics like detecting deception, false memories, presenting forensic evidence in court, investigative interviewing, risk assessment, offenders, victims and eyewitness identification (see program). This year’s conference took place during the 24-27th of June in St. Petersburg and I summarised a selection of talks given during this conference.
Tuesday the 24th of June, 2014 Symposium 16.30-18.00 – Allegation: True or false
Van Koppen: I don’t know why I did it: motives for filing false allegations of rape. The first in a series of three talks (see Horselenberg & de Zutter). Explained the basis of the false allegations of rape in a Dutch & Belgian research project. Their conclusions are that the existing data (Viclas) and models are insufficient. Researchers on the current project went through rape cases between 1997-2011 and found more than 50 false allegations. Subsequently, they investigated the reasons why these people made false allegations and found in addition to the already known factors (especially emotional reasons and the alibi factor were often present; on the other hand, mental issues and vigilance were not) that in a substantial amount of cases it was unknown why this person made a false allegation of sexual abuse. Some people reported not knowing why they made the false allegation (even when pressured by the interviewer to provide a reason), and in other cases the researchers couldn’t find out because the police hadn’t asked or did not write down the reasons down, so it wasn’t in the case file. In conclusion, false allegations of rape happen, they cause problems, and it is not always clear why people make these false allegations.
