Collectivist cultures are characterized by greater concern for ingroup members than self-interest, whereas the reverse is true for individualistic cultures. In light of evidence suggesting that collectivist countries are more likely than individualistic countries to have near-universal compliance with infection-preventive behaviors such as public m...

Purpose: We conducted studies in two Western, individualistic countries, Canada and the United States, to assess the impact of political ideology on governmental policies (e.g., implementation of mask mandates) and individual conduct (e.g., getting vaccinated) in response to the COVID19 pandemic, as well as infection and death rates. We argue that...

Efficacy of SARS-CoV-2 (COVID-19) vaccines was assessed by comparing infection and death rates in the eight most-and eight least-fully-vaccinated German states. Infection and death rates were measured on three dates in fall 2021. Less-vaccinated states had substantially higher infection and death rates than more-vaccinated states. These effects occ...

We argue that conservative political ideology is associated with poorer handling of COVID-19. In Study 1, Canadian provinces and territories were categorized in terms of whether there was a conservative majority in power. Infection and death rates in conservative provinces were higher and rose faster. Conservative provinces had higher infection and...

Efficacy of COVID-19 (SARS-CoV-2) vaccines was assessed by comparing infection and death rates in the eight most- and eight least-vaccinated states in Germany. Infection and death rates were measured on October 18, November 18, and December 1, 2021. States with lower rates of full vaccination had substantially higher infection and death rates than...

Subramanian and Kumar found that COVID-19 vaccination rates were unrelated to infection rates across 68 countries and 2947 U.S. counties. We argue that their null effects resulted from 1) failure to attend to other variables related to infection rates that could obscure the ability to detect relationships between vaccination and infection rates and...

COVID-19 Infection Rates Are Related to Population Rates of Vaccination: A Response to Subramanian and Kumar (Corrected) Subramanian and Kumar (2021) found that COVID-19 vaccination rates were unrelated to infection rates across 68 countries and 2947 U.S. counties. We argue that their null effects resulted from 1) failure to attend to other varia...

Enormous cross-national differences exist in COVID-19 infection and death rates. Collectivist cultures are characterized by greater concern for ingroup members than for self-interest, whereas the reverse is true for individualistic cultures. In light of evidence suggesting that countries with collectivist cultures are more likely than countries wit...

A study addressed the differences between conservative versus nonconservative governments in the ten provinces and three territories in Canada on COVID-19 infection per million and death per million rates. The results showed higher rates for conservative governments and both variables. The magnitude of these effects was relatively unaffected by pop...

We computed the number of COVID-19 infections and deaths per million people for the 50 states and Washington, DC and categorized them as supporting Biden versus Trump in the 2020 U.S. presidential election. There were significantly fewer infections per million, but not deaths per million, in states in which Biden won the majority of the vote than i...

A study addressed the relationship between the degree of conservativism of the governments of the ten provinces and three territories in Canada and infection per million (IPM) and death per million (DPM) rates. The results showed a positive relationship between degree of conservatism and both IPM and DPM rates. The magnitude of these relationships...

We computed the number of COVID-19 infection rates per million people for the 50 states and Washington, DC and categorized them as supporting Biden versus Trump in the 2020 presidential election in The United States of America. There were significantly lower infection rates in states that supported Biden. An analysis of covariance (ANCOVA) controll...

Enormous cross-national differences exist in COVID-19 death rates. Collectivist cultures are characterized by greater concern for ingroup members than for self-interest, whereas the reverse is true for individualistic cultures and countries. In light of this cultural difference, and evidence suggesting that cultures known for their collectivist ori...

Enormous differences exist in rates of death from COVID-19 in countries around the world. Collectivist cultures and countries are characterized by concern for culture and country to a greater extent than for self-interest, whereas the reverse is true for individualistic cultures and countries. In light of this cultural difference, and suggestive ev...

The authors examined the role of intrinsic interest in mediating the relationship among mood, processing goals, and task performance. Participants in induced happy, neutral, or sad moods generated similarities and differences between TV shows using performance-based, enjoyment-based, or no stop rule (cf. L. L. Martin, D. W. Ward, J. W. Achee, & R....
