Novel coronavirus (SARS-CoV-2) disease (COVID-19) spread from Wuhan in China (2019) around the globe and this pandemic of 2020 was a salient public health emergency and psychosocial shock event that influenced the lives of almost all humans on Earth. This study synthesizes the pandemic processes over timescape 2020-24, from the >663 million humans who were infected over 2020-21 when >21.3 million died due to Covid and secondary excess mortality, and >70% of all humans were subjected to various societal restrictions and lockdowns, such as ~4.5 billion humans over may 2020 alone. The societal lockdowns and largest global economic peturbation in a century (-3% world GDP, xx% peak inflation, rent from xx to xx, energy prices rose xx%), which coincided with a collective drop in life expectancy and mental health and well-being, especially more anxiety, depression, suicides, and domestic violence against women and children were recorded. Coronavirus exploited social contact and transport, urbanization, liberalism, anxiety, and societal lockdowns.
Humans showed marked emotional, cognitive, physical, social, and societal responses over 2020-23, and the collective focused on virus mutations, vaccines, breakthrough infections, long-Covid, and more stress, loneliness, polarization, demonstrations, riots, violence, and conspiracy theories, with more authoritarianism and government coups around the globe (e.g., US Insurrection, 2021). When Russia invaded Ukraine (≥22w8) war returned to Europe, and globally more refugees were observed than since the second world war (WW2). Over 2020-24 we witnessed major individual, sociocultural, geopolitical, and technological changes, from the rise of TikTok and mainstream Artifical Intelligence (ChatGTPo4) to #BLM and second wave of #MeToo, which affected the collective psyche and discourse, and coronavirus and overt nuclear threat coincided with an unprecedented series of natural disasters and record heatwaves that confirmed humans had created a #ClimateCrisis of planetary proportions. Over 2023-24 the planetary climate ventured into uncharted territory driven by the human industrial revolution (>1830). Most humans described the pandemic years 2020-22 as the hardest and most stressful years they had experienced in their lifetime, which affected a generation of young humans. Over 2023 the collective return to “normalcy” was hampered by Ukranian and Israelian wars, cost-of-living crisis, and climate disasters that made humans realize the world had changed into an era of conflict. The pandemic timescape 2020-23 was an unique period in time to learn about human psychology and collective preparedness (a natural experiment), as engagement with natural hazards is a master task of civilizations. Psychological theories could be examined across contexts and in diverse samples, who were often exposed to comparable collective stressors of personal significance. Such perturbations can help to study human stress dynamics and complex social systems, beyond what can be learned from more stable periods. The collective changes and interconnected consequential events over 2020-23 including the global rise in military spending, government control, radical right politics, and a decline in freedom of speech, made this timescape a mini "Axial-period" that shapes the decades ahead.
