Interview: Bridging the Digital Divide - [10/21]
November, 2022 [Journal of Quantitative Description: Digital Media, 2022]
Digital literacy is a measure of how effectively individuals can navigate digital spaces and contextually understand the information they come across. Using a field sample of 674 Facebook users in Pakistan, we study the correlates of digital literacy and its association with the ability to discern between true and fake information.

Despite the popularity of entry-level smartphones in developing countries, little is known about how mobile video performs over such devices. We conducted the first empirical evaluation of mobile video performance under memory pressure. Our user study measures how frequently smartphones encounter memory pressure. We explore various strategies for reducing the impact of memory pressure.

Today, more than 200 million users use Android Go, a mobile operating system for entry-level smartphones. Yet little is known about its impact on mobile Web performance. We conducted the first empirical study about the causal impact of Android Go using controlled experiments and a set of methodological approaches from the econometrics literature.

The uncertainty surrounding the COVID-19 pandemic has been fueled by the COVID-19 “infodemic.” We evaluated the relationship between individual differences in cognitive reflection and the ability to discern between true and false COVID-19 information using a random sample of 621 low- and middle-income users in Pakistan. We find that higher cognitive reflection test scores are associated with greater truth discernment for COVID-19 headlines, less trust but greater use of formal information sources, and greater demand for KN95 masks.
