Understanding and managing the Self-Wise during a healthcare crisis.

The COVID-19 pandemic has brought an interesting yet worrisome phenomenon to the fore. A segment of the population, which we call the Self-Wise, seems to exhibit an inflated sense of self-expertise relative to domain experts, which - combined with a lack of trust in the latter - leads them to ignore or reject expert advice. We argue and demonstrate that this phenomenon is distinct from other "illusory superiority" phenomena, most notably Dunning-Kruger and Lake Wobegon.

COVID-19 information overload and generation Z's social media discontinuance intention during the pandemic lockdown.

While previous research highlights the benefits of social media in times of a pandemic, this research focuses on the potential dark side of social media use among Generation Z (Gen Z) in the UK during the COVID-19 pandemic lockdown between March and May 2020. The study reveals that COVID-19 information overload through social media had a negative impact on Gen Z social media users' psychological well-being. Moreover, perceived information overload heightened both social media fatigue and fear of COVID-19, which, in turn, increased users' social media discontinuance intention.
