Zusammenfassung: Nudging hat das Potential, soziales Engagement zu erhöhen. In diesem Beitrag wird ausgehend von einigen Feldexperimenten diskutiert, wie vorgegebene Standards, Anker, Erinnerungen und weitere Methoden des Nudgings die Entscheidung, Geld für wohltätige Zwecke zu spenden, verändern können. So beeinflussen zum Beispiel nicht bindende Empfehlungen bezüglich der Spendenhöhe die Höhe der tatsächlich gespendeten Beträge. Einige Individuen entscheiden sich dann eher dafür, genau den empfohlenen und nicht einen anderen Betrag zu spenden. Dabei erhöhen einige ihre Spende, während andere sie verringern. Außerdem spenden mehr Personen, wenn die Empfehlung relativ niedrig ist, und weniger, wenn sie relativ hoch angesetzt wird. Insgesamt kann es deshalb durch eine empfohlene Spendenhöhe genauso gut zu einer Erhöhung wie zu einer Verringerung des insgesamt erzielten Spendenaufkommens kommen. Im Beitrag wird argumentiert, dass die Entscheidungen für ein bestimmtes Spendendesign nicht einfach sind und den jeweiligen Kontext berücksichtigen sollten. Zuletzt wird darauf hingewiesen, dass es keine „nudgingfreie“ Situation gibt, denn der Status quo, „nicht zu spenden“, ist auch ein Default. Summary: Nudging shows a potential to increase social engagement. The article discusses a series of large field experiments in which nudging techniques such as defaults, anchors, or reminders were implemented. The results suggest that nudging may influence donation decisions. Thus, for example, nonbinding donation recommendations change the distribution of contribution levels. More individuals choose to donate exactly the recommended amount. Some raise whereas others lower their contribution. More people donate if the recommendation is relatively low and less do so if it is relatively high. The overall effect is not clear ex ante. This and other examples show that design decisions are not simplistic and furthermore context dependent. Finally, it is demonstrated that nudging-free situations do not exist because the status quo “non-donor” is also a default.

Ex Ante

Abstract One limitation of stated-preference methods is the formation of hypothetical bias. To address this, the honesty oath has been used as an ex ante technique to reduce hypothetical bias. Our study provides a query account of the honesty oath in a discrete-choice experiment setting by using Query Theory to examine the mechanism behind the effectiveness of the honesty oath. Our results show that the honesty oath can change the content and order of queries; potentially reducing hypothetical bias in discrete choice experiments. The study suggests the potential usefulness of Query Theory in examining thought processes of respondents in valuation studies.

Abstract Cushman characterizes rationalization as the inverse of rational reasoning, but this distinction is psychologically questionable. Coherence-based reasoning highlights a subtler form of bidirectionality: By distorting task attributes to make one course of action appear superior to its rivals, a patina of rationality is bestowed on the choice. This mechanism drives choice and action, rather than just following in their wake.

Asch’s seminal research on “Forming Impressions of Personality” (1946) has widely been cited as providing evidence for a primacy-of-warmth effect, suggesting that warmth-related judgments have a stronger influence on impressions of personality than competence-related judgments (e.g., Fiske, Cuddy, & Glick, 2007 ; Wojciszke, 2005 ). Because this effect does not fit with Asch’s Gestalt-view on impression formation and does not readily follow from the data presented in his original paper, the goal of the present study was to critically examine and replicate the studies of Asch’s paper that are most relevant to the primacy-of-warmth effect. We found no evidence for a primacy-of-warmth effect. Instead, the role of warmth was highly context-dependent, and competence was at least as important in shaping impressions as warmth.

Changing environmental context during encoding can influence episodic memory. This study examined the memorial consequences of environmental context change in children. Kindergartners, first and fourth graders, and young adults studied two lists of items, either in the same room (no context change) or in two different rooms (context change), and subsequently were tested on the two lists in the room in which the second list was encoded. As expected, in adults, the context change impaired recall of the first list and improved recall of the second. Whereas fourth graders showed the same pattern of results as adults, in both kindergartners and first graders no memorial effects of the context change arose. The results indicate that the two effects of environmental context change develop contemporaneously over middle childhood and reach maturity at the end of the elementary school days. The findings are discussed in light of both retrieval-based and encoding-based accounts of context-dependent memory.
