Previous social engineering research in a real-world setting has shown an interaction between the personality of the target and the persuasion principle used. This study investigated whether this interaction is present in the realm of email phishing. Additionally, a signal detection theory framework was used to evaluate how the various persuasion principles influence accuracy, sensitivity (d’), and response criterion placement. A personality inventory and an email identification task (phishing or legitimate) were used. These data support previous findings that high extroversion is predictive of increased susceptibility to phishing attacks. The various persuasions principles elicited diverse response criterions and sensitivities, though all investigated persuasion principles resulted in a liberal decision criterion, except one. These findings are interpreted and discussed.}, journal={APPLIED ERGONOMICS}, publisher={Elsevier BV}, author={Lawson, Patrick and Pearson, Carl J. and Crowson, Aaron and Mayhorn, Christopher B.}, year={2020}, month={Jul} }

The Effects of Pedigree in a Dual Advisor Context}, volume={822}, ISBN={["978-3-319-96076-0"]}, ISSN={["2194-5365"]}, DOI={10.1007/978-3-319-96077-7_2}, abstractNote={Source type bias (human vs automation) may influence the development of trust in decision aids. Situations involving two decision-aids may depend on the influence of pedigree (perceived expertise) such that decision making or reliance behavior is affected. In this task, the Convoy Leader decision-making paradigm developed by Lyons and Stokes (2012) was adapted to address advisor pedigree such that the human and automated information sources could be of high or low pedigree. Two hundred participants were asked to make eight decisions regarding the route taken by a military convoy based on intelligence (e.g., past insurgent attacks, Improvised Explosive Devices (IEDs) detected, etc.) provided by two information sources (human and automation) of varying degrees of pedigree. In two of these eight decisions, the decision-aids provided conflicting information. Results indicated that participants were likely to demonstrate a bias such that they were more likely to trust the information coming from the human advisor regardless of pedigree. This bias towards the human was only reversed when the automated decision aid was presented as having far greater pedigree. Measures of trust attitudes were highly indicative of decision making behaviors. The findings are addressed in terms of design within a dual-advisor context where human operators may receive conflicting information from advisors of different source types.}, journal={PROCEEDINGS OF THE 20TH CONGRESS OF THE INTERNATIONAL ERGONOMICS ASSOCIATION (IEA 2018), VOL V: HUMAN SIMULATION AND VIRTUAL ENVIRONMENTS, WORK WITH COMPUTING SYSTEMS (WWCS), PROCESS CONTROL}, author={Pearson, Carl J. and Mayhorn, Christopher B.}, year={2019}, pages={10–17} }

Pedigree's unique bias on trust between human and automated advisers}, volume={81}, ISSN={["1872-9126"]}, DOI={10.1016/j.apergo.2019.102907}, abstractNote={We assessed the effects of source type bias (human or automation) on adviser trust in a dual adviser decision-making task.Source type and reliability's effects on adviser trust have been studied in a dual-adviser context, but the influence of pedigree (perceived expertise) across source types lacked robust investigation. As situations with two decision-aids of uneven pedigree can easily arise, it is critical to understand how operators are biased towards a decision-aid of a certain source type and pedigree.A decision-making task similar to the paradigm of Convoy Leader (Lyons and Stokes, 2012) was given to participants, where a military convoy route had to be selected in the presence of IEDs and insurgent activity. We measured behavioral reliance and trust attitudes. Pedigree was manipulated via controlled adviser descriptions, in a manner consistent with past investigations (Madhavan and Wiegmann, 2007a).We found a trust bias towards the human adviser, reversed only when there is a far greater pedigree in the automated adviser. Trust attitudes were also strongly indicative of reliance behaviors.Pedigree is a strong influencer of trust in a decision-aid and biased towards human advisers. Trust is highly predictive of reliance decisions.System designers must take care with how "expert" automation is portrayed, particularly if it is used in conjunction with other human advisers (e.g.: conflicting advice from air-traffic control and an onboard system).}, journal={APPLIED ERGONOMICS}, publisher={Elsevier BV}, author={Pearson, Carl J. and Geden, Michael and Mayhorn, Christopher B.}, year={2019}, month={Nov} }
