“Don’t Sweat It: Ambient Temperature Does Not Affect Social Behavior and Perception”, Jan S. Krause, Gerrit Brandt, Ulrich Schmidt, Daniel Schunk2023-08-18 (crime, cognitive bias)⁠:

[OSF] Literature suggests that human perception and behavior vary with physical temperature. We conducted an experiment to study how different ambient temperatures impact social behavior and perception: subjects undertook a series of tasks measuring various aspects of social behavior and perception under 3 temperature conditions (cold vs. optimal vs. warm).

Despite well-established findings on the effects of temperature, our data suggest that ambient temperature has no relevant influence on social behavior and perception.

We corroborate our finding of a null effect using equivalence testing and provide a discussion considering recent failed replication attempts in this field of research and related studies on heat and violence.
