Summer Heat Wave

Summer has officially hit in Bloomington and across the country.  It is hot and humid. People are wilting and as a result are more likely to be impatient and irritable.  Psychologists have argued for decades that heat waves are associated with violent action and crime due to increased aggressive thoughts and feelings of hostility (Anderson 1989; 2001; Cohn and Rotton 2000). More crimes are reported during the summer than other seasons (Cohn and Rotton 2000).

If heat is related to hostility and aggression, is it related to protest participation? I’d suspect that protests are more likely to occur in summer months when more people are out and about in public spaces.  People may also have more time off in the summer to engage in protests.

Are protests less likely to occur in the winter?  Certainly, some protests have occurred during the winter, such as the Occupy protests. But were these an exception? And thinking more broadly, has there been research on how movements are influenced by environmental conditions such as weather, ecosystems, spatial layouts of communities, etc.?


My quick search on movements and weather did not yield any results. Does anyone know if there is any research on how environmental conditions influence movements? If not, maybe someone should start looking into this further…

  1. Yes, check ck the economists who published in QJE on the tea party. They used weather in an IV model.
