Is negativity bias intuitive for liberals and conservatives?

Area of Science:

• Social Psychology
• Cognitive Science
• Political Psychology

Background:

• Existing research indicates conservatives exhibit greater negativity bias than liberals.
• Previous studies often rely on correlational data, lacking insight into cognitive mechanisms.
• Negativity bias is defined as interpreting ambiguous stimuli, such as faces, as threatening.

Purpose of the Study:

• To investigate if cognitive load (intuition) influences negativity bias.
• To examine if cognitive load mitigates ideological differences in negativity bias.
• To test these hypotheses in underrepresented, non-Western samples in Turkey.

Main Methods:

• A laboratory experiment manipulated cognitive load using high-load vs. low-load conditions.
• Participants' political orientation (liberal vs. conservative) was assessed.
• Two online experiments used time-limit manipulations for replication attempts during the COVID-19 pandemic.

Main Results:

• Negativity bias significantly increased under high cognitive load in the lab experiment.
• The effect of cognitive load on negativity bias was moderated by political orientation.
• Liberals showed increased negativity bias under high cognitive load, resembling conservatives.
• Replication attempts in online experiments failed to confirm these findings.
• The COVID-19 pandemic context might have influenced baseline negativity bias.

Conclusions:

• Findings provide limited evidence that intuition (via cognitive load) promotes negativity bias.
• The study questions whether liberals consistently exert cognitive effort to avoid this perceptual bias.
• Ideological asymmetry in negativity bias may be context-dependent and not solely intuition-driven.
