Noncoercive human intelligence gathering

Despite widespread recognition that coercive methods for intelligence gathering are unethical and counterproductive, there is an absence of empirical evidence for effective alternatives. We compared two non-coercive methods - the Modified Cognitive Interview (MCI) and Controlled Cognitive Engagement (CCE), adapted for intelligence gathering by adding a moral frame to encourage interviewees to consciously consider sharing intelligence. Participants from the general population experienced an unexpected live event where equipment was damaged, and an argument ensued. Prior to interview, participants were incentivised to withhold information about a target individual implicated in the event. CCE yielded more target information, more frequently than MCI (67% vs. 36%). Similarly, framing yielded target information more often (65% vs. 39%). The effects of interview and framing appear to be additive rather than interactive. Our results indicate combining non-coercive interview methods with moral framing can enhance intelligence gain

Finding a needle in a haystack: toward a psychologically informed method for aviation security screening

Current aviation security systems identify behavioral indicators of deception to assess risks to flights, but they lack a strong psychological basis or empirical validation. We present a new method that tests the veracity of passenger accounts. In an in vivo double-blind randomized-control trial conducted in international airports, security agents detected 66% of deceptive passengers using the veracity test method compared with less than 5% using behavioral indicator recognition. As well as revealing advantages of veracity testing over behavioral indicator identification, the study provides the highest levels to date of deception detection in a realistic setting where the known base rate of deceptive individuals is low

The Lattice Structure of Connection Preserving Deformations for q-Painlev\'e Equations I

We wish to explore a link between the Lax integrability of the $q$-Painlev\'e equations and the symmetries of the $q$-Painlev\'e equations. We shall demonstrate that the connection preserving deformations that give rise to the $q$-Painlev\'e equations may be thought of as elements of the groups of Schlesinger transformations of their associated linear problems. These groups admit a very natural lattice structure. Each Schlesinger transformation induces a B\"acklund transformation of the $q$-Painlev\'e equation. Each translational B\"acklund transformation may be lifted to the level of the associated linear problem, effectively showing that each translational B\"acklund transformation admits a Lax pair. We will demonstrate this framework for the $q$-Painlev\'e equations up to and including $q$-$\mathrm{P}_{\mathrm{VI}}$

Symmetries in Connection Preserving Deformations

We wish to show that the root lattice of B\"acklund transformations of the $q$-analogue of the third and fourth Painlev\'e equations, which is of type $(A_2+ A_1)^{(1)}$, may be expressed as a quotient of the lattice of connection preserving deformations. Furthermore, we will show various directions in the lattice of connection preserving deformations present equivalent evolution equations under suitable transformations. These transformations correspond to the Dynkin diagram automorphisms
