During COVID-19, both personal and national outlooks initially showed decline. While personal views improved post-restrictions, national perceptions remained negative, indicating a pervasive negativity bias.
Area of Science:
- Psychology
- Social Psychology
- Cognitive Science
Background:
- Mental representations of the self and collectives can follow intertemporal trajectories (progress, decline, stasis).
- Major public events, like COVID-19 restrictions, may influence these temporal self and collective perceptions.
- Implicit temporal trajectories are inferred from cognitive availability of positive/negative events across time (past memory vs. imagined future).
Purpose of the Study:
- To examine the relationship between intertemporal trajectories for the self and the nation.
- To investigate how these trajectories changed during and after COVID-19 restrictions in American and British samples.
- To explore the influence of major public events on personal and collective temporal thought.
Main Methods:
- Assessed implicit temporal trajectories via cognitive availability of positive and negative events across time.
- Collected data from American and British samples at the beginning and end of major COVID-19 restrictions.
- Analyzed explicit beliefs about national progress, decline, and hope.
Main Results:
- At the start of COVID-19 restrictions, both personal and collective temporal thought showed implicit decline trajectories (future less positive than memory).
- Personal implicit decline trajectories attenuated after restrictions lifted, suggesting reversibility of positivity biases.
- Collective temporal thought exhibited a pervasive negativity bias, with the future consistently perceived as more negative than the past, irrespective of restrictions.
Conclusions:
- Major public events can override typical positivity biases in personal temporal thought.
- Collective temporal thought demonstrates a persistent negativity bias, particularly concerning the national future.
- Explicit national beliefs align with implicit temporal biases in collective thought.
