Historical narratives about the COVID-19 pandemic are motivationally biased
Historical narratives about the COVID-19 pandemic are motivationally biased
The accuracy of an individual's recollection of the COVID-19 pandemic is influenced by motivational factors, such as their vaccination status and feelings, resulting in divergent retrospective narratives and potentially impacting their assessment of past political actions, with implications for future crisis preparedness.

The association between vaccination status identification and societal polarization
Drawing from large samples of vaccinated and unvaccinated people, this article uncovers associations between
people's identification with their COVID-19 vaccination status and polarization in attitudes, behaviors, and
acceptance of vaccination policies.

Ok Google: Using virtual assistants for data collection in psychological and behavioral research
Because of the increasing popularity of voice-controlled virtual assistants, such as Amazon's Alexa and the Google Assistant, they
should be considered a new medium for psychological and behavioral research. This article presents two studies analyzing the reliability and validity of data collected through the medium.
