We contribute to the deception literature by offering analyses at the sentence level to locate where emotion is most pronounced in deceptive versus truthful texts. Using two public data sets—news articles (Study 1) and hotel reviews (Study 2)—we found that maximum emotion occurs toward the beginning of deceptive texts while maximum emotion appears later for truthful texts. In addition to demonstrating the effect across diverse settings, we used two different measurements for emotion and separated the results by valence, replicating the maximum emotion effect each time. The predictive nature of maximum affect ranged from 54% to 56% across data sets, a rate consistent with most deception studies using 50-50 lie–truth base rates. Implications for future research and deception theory are discussed."

In response, online retailers aim to facilitate search by attaching descriptive terms to their inventory (e.g., product genres or categories). Called “tagging,” such a practice has been shown to increase product visibility/exposure in an otherwise limitless sea of options. Across five distinct platforms covering a gamut of consumer domains (i.e., food recipes, mobile games, books, videos, and journal publications), we find that the benefits of tagging for product visibility/exposure come with unexpected costs. Indeed, though assigning more tags to a product does indeed boost its visibility/exposure online, doing so also hurts said product’s perceived quality. This effect emerges regardless of proxies used to quantify (i) visibility/exposure or (ii) product liking. We draw on categorization and learning research to explain these results. While multi-tagging increases the likelihood of a product to appear in consumers’ search, it also increases the likelihood of a mismatch between what consumers really sought and what said product can actually deliver."

We introduce an automated tool to identify passive voice from large-scale text data, PassivePy, a Python package (readymade website: https://passivepy.streamlit.app/). This package achieves 98% agreement with human coded data for grammatical voice as revealed in two large validation studies. In this paper, we discuss how PassivePy works, and present preliminary empirical evidence of how passive voice connects to various behavioral outcomes across three contexts relevant to consumer psychology: product complaints, online reviews, and charitable giving. Future research can build on this work and further explore the potential relevance of passive voice to consumer psychology and beyond."

Across 12 field and lab studies, we explore when, why, and for whom the information load carried in TED talks causes them to gain (vs. lose) popularity. First and foremost, we uncover a negative effect whereby increases in the number of topics broached in a talk (i.e., information load) hurt viewer adoption. The cause? Processing disfluency. As information load soars, content becomes more difficult to process, which in turn reduces interest. Probing process further, we show this effect fades among audience members with greater need for cognition, a personality trait marking a penchant for deep and broad information processing. Similarly, the effect fades among edutainment viewers favoring education goals (i.e., cognitive enrichment) whereas it amplifies among those favoring entertainment (i.e., hedonic pleasure). Our investigation also documents the counterintuitiveness of our findings (i.e., how individuals mispredict which talks they would actually [dis]like). From these results, we derive theoretical insights for processing fluency research and the psychology of cultural products adoption (i.e., we weigh in on when, why, and for whom fluency has favorable vs. unfavorable downstream effects). We also derive prescriptive insights for (a) players of the edutainment industry whose very business hinges on curating appealing content (e.g., TED, Talks@Google, The Moth, Big Think, Spotify) and (b) communicators of all creeds wishing to broaden their reach and appeal (e.g., professors, scientists, politicians, journalists, bloggers, podcasters, content editors, online community managers).
