Query: What Makes People Install a COVID-19 Contact-Tracing App? Understanding
  the Influence of App Design and Individual Difference on Contact-Tracing App
  Adoption Intention   Smartphone-based contact-tracing apps are a promising solution to help scale
up the conventional contact-tracing process. However, low adoption rates have
become a major issue that prevents these apps from achieving their full
potential. In this paper, we present a national-scale survey experiment ($N =
1963$) in the U.S. to investigate the effects of app design choices and
individual differences on COVID-19 contact-tracing app adoption intentions. We
found that individual differences such as prosocialness, COVID-19 risk
perceptions, general privacy concerns, technology readiness, and demographic
factors played a more important role than app design choices such as
decentralized design vs. centralized design, location use, app providers, and
the presentation of security risks. Certain app designs could exacerbate the
different preferences in different sub-populations which may lead to an
inequality of acceptance to certain app design choices (e.g., developed by
state health authorities vs. a large tech company) among different groups of
people (e.g., people living in rural areas vs. people living in urban areas).
Our mediation analysis showed that one's perception of the public health
benefits offered by the app and the adoption willingness of other people had a
larger effect in explaining the observed effects of app design choices and
individual differences than one's perception of the app's security and privacy
risks. With these findings, we discuss practical implications on the design,
marketing, and deployment of COVID-19 contact-tracing apps in the U.S.
