DECEPTION All warfare is based upon deception. Deception, the employment of trickery or guile, is equal parts art and science. It is typically defined as " causing another to believe what is not true; to mislead or ensnare " (Webster's, 1999). Deception aims to deliberately induce misperception in another. Deception is a deliberate enterprise; it is not the result of chance, nor the by-product ...

Deception has been extensively studied in many disciplines in social science. With the increasing use of instant messaging (IM) in both informal communication and performing tasks in work place, deception in IM is emerging as an important issue. In this study, we aimed to explore the online behavior of deception in a group IM setting. The empirical results from triadic groups showed that two ty...

Automatic deception detection is an important task that has gained momentum in computational linguistics due to its potential applications. In this paper, we propose a simple yet tough to beat multi-modal neural model for deception detection. By combining features from different modalities such as video, audio, and text along with Micro-Expression features, we show that detecting deception in r...

Self-deception is a special kind of motivational dominance in belief-formation. We develop criteria which set paradigmatic self-deception apart from related phenomena of auto-manipulation such as pretense and motivational bias. In self-deception rational subjects defend or develop beliefs of high subjective importance in response to strong counter-evidence. Self-deceivers make or keep these bel...

Philosophers, psychologists, and economists have long asserted that deception harms trust. We challenge this claim. Across four studies, we demonstrate that deception can increase trust. Specifically, prosocial lies increase the willingness to pass money in the trust game, a behavioral measure of benevolence-based trust. In Studies 1a and 1b, we find that altruistic lies increase trust when dec...

Arguments about the morality of the use of deception in patient care have been conducted largely in an empirical vacuum, with few data about the situations in which deception occurs. Do staff frequently deceive their patients and, if so, under what conditions? Can the consequences of deception always be foreseen? What justifications do staff use to explain their behaviour? The small-scale study...

Deception is an important element in all natural and organisational systems. This paper outlines the fundamental principles of deception, and applies them to general information systems. It examines the two fundamental methods of deception: data and context manipulation. It also briefly examines the motives for deception.

The community deception problem is about how to hide a target community C from community detection algorithms. The need for deception emerges whenever a group of entities (e.g., activists, police enforcements) want to cooperate while concealing their existence as a community. In this paper we introduce and formalize the community deception problem. To solve this problem, we describe algorithms ...

(2013) Deceptively simple The deception-general ability and the need to put the liar under the spotlight. This Focused Review expands upon our original paper (You can't kid a kidder": Interaction between production and detection of deception in an interactive deception task. Frontiers in Human Neuroscience, 6:87). In that paper we introduced a new socially interactive, laboratory-based task, th...

The present study focused on neural correlates underlying second-order deception. In first-order deception, the recipient of deception is unaware of the deceiver's deceptive intention. However, during second-order deception, the recipient is fully aware of the deceiver's deceptive intention and thus the deceiver needs to use both lies and truths to deceive the recipient. Using the functional ne...
