The fateful first consumer review
https://pubsonline.informs.org/doi/10.1287/mksc.2020.1264 This paper uncovers the striking power of a product’s first consumer review. Our analytical model suggests that two key metrics of online consumer reviews, valence and volume, are not independent, but instead evolve interdependently. This interdependence forms a mechanism to transfer *a (dis)advantage from a product’s first review to...
Timing matters when correcting fake news
https://www.pnas.org/content/118/5/e2020043118 Countering misinformation can reduce belief in the moment, but corrective messages quickly fade from memory. We tested whether the longer-term impact of fact-checks depends on when people receive them. In two experiments (total N = 2,683), participants read true and false headlines taken from social media. In the treatment...
Synchronized eye movements predict test scores in online video education
https://www.pnas.org/content/118/5/e2016980118.abstract Experienced teachers pay close attention to their students, adjusting their teaching when students seem lost. This dynamic interaction is missing in online education. We hypothesized that attentive students follow videos similarly with their eyes. Thus, attention to instructional videos could be assessed remotely by tracking eye movements. Here we...
Experienced well-being rises with income, even above $75,000 per year
https://www.pnas.org/content/118/4/e2016976118.abstract What is the relationship between money and well-being? Research distinguishes between two forms of well-being: people’s feelings during the moments of life (experienced well-being) and people’s evaluation of their lives when they pause and reflect (evaluative well-being). Drawing on 1,725,994 experience-sampling reports from 33,391 employed US adults, the present...

Empathy is the mother of invention: Emotion and cognition for creativity in the classroom
https://journals.sagepub.com/doi/10.1177/1365480221989500 According to the age-old proverb from Plato’s Republic: necessity is the mother of invention, the main motivation for creating new discoveries is the need for them. However, as well as the necessity factor, we argue that a very important aspect that influences invention and creativity is the empathy factor....
A longer shortlist increases the consideration of female candidates in male-dominant domains
https://www.nature.com/articles/s41562-020-01033-0 Making it onto the shortlist is often a crucial early step toward professional advancement. For under-represented candidates, one barrier to making the shortlist is the prevalence of informal recruitment practices (for example, colleague recommendations). The current research investigates informal shortlists generated in male-dominant domains (for example, technology executives) and...
Hegemonic masculinity predicts 2016 and 2020 voting and candidate evaluations
https://www.pnas.org/content/118/2/e2020589118 This work examined whether the endorsement of the culturally idealized form of masculinity—hegemonic masculinity (HM)—accounted for unique variance in men’s and women’s support for Donald Trump across seven studies (n = 2,007). Consistent with our theoretical backdrop, in the days (Studies 1 and 2) and months (Studies 3 through...
Transforming task representations to perform novel tasks
https://www.pnas.org/content/117/52/32970.abstract https://arxiv.org/abs/2005.04318 An important aspect of intelligence is the ability to adapt to a novel task without any direct experience (zero shot), based on its relationship to previous tasks. Humans can exhibit this cognitive flexibility. By contrast, models that achieve superhuman performance in specific tasks often fail to adapt to...
개발자 비급 - 5. 스타트업의 개발자 채용비법
http://channy.creation.net/blog/1443 1. 동업자 같은 사람을 찾아라 스타트업에서 가장 중요한 사람은 창업자입니다. 단기적으로 민첩성을 가지고 사업을 구성하고 실행하려면, 창업자와 같은 마인드를 가진 사람이 많아야 그 회사는 성공합니다. 사업과 기술을 보는 눈이 같은 사람, 빠르게 배우고 무모한 일도 도전하는 업무 방식 및 성격, 그리고 심지어 식성(?)까지 비슷해야 합니다. 그래서 저는 창업자들에게 개발자를...
