TL;DR: An empirical study of two cognitive biases: conservatism and loss aversion was reported on, showing that the two biases can occur simultaneously and can have a huge impact on decision-making.
Abstract: Software is playing an increasingly important role in supporting human decision-making. Previous HCI research on decision support systems (DSS) has improved the information visualization aspect of DSS information design, but has somewhat overlooked the cognitive aspect of decision-making, namely that human reasoning is heuristic and reflects systematic errors or cognitive biases. We report on an empirical study of two cognitive biases: conservatism and loss aversion. Two remediation techniques recommended by previous research were tested: the expected return method, an actuarial-inspired approach presenting objective metrics; and bootstrapping, a technique successful in improving judgment consistency. The results show that the two biases can occur simultaneously and can have a huge impact on decision-making. The results also show that the two debiasing techniques are only partly effective. These findings suggest a need for more research on debiasing, and indicate some directions for exploring debiasing techniques and building decision support systems.

TL;DR: The design and use of the #selfiestation, a kiosk for taking selfies deployed in an office of a large enterprise, is described and its use was studied through analysis of 821 photos taken by 336 users over 24 weeks and interviews with 10 users.
Abstract: This paper describes the design and use of the #selfiestation, a kiosk for taking selfies. Deployed in an office of a large enterprise, its use was studied through analysis of 821 photos taken by 336 users over 24 weeks and interviews with 10 users. The findings show high adoption amongst residents (81.5 %); describe selfie usage patterns (funatics, communicators, check-ins, doppelgangers, and groupies); illustrate social photo-taking behavior (78.6 % of users posed as part of groups, and those who did took almost four times as many photos); and raises questions for future investigations into flexibility in self-representation over time. Office residents seeing social and community-building value in selfies suggests that they have a place in the enterprise.

TL;DR: In this article, a method for injecting information into a deliberation includes extracting at least one concept from a plurality of statements asserted by a group of participants, correlating the concept to a goal of the deliberation, tagging the asserted statements with an identifier of a participant who asserted the statement, clustering participants according to a slant on each of the concepts, and searching, using the concept, tagged statements and a cluster of participants for new information or concepts that negate the slant that is not in agreement with the goal.
