Daily brief research updates from the cognitive sciences
I am sure we all know that feeling of getting more irritable when temperatures rise. Well, now we have some fascinating research to show that that irascibility is also measurable in the amount of hate speech online.
We may assume that hate speech is simply the language of a number of opinionated and disagreeable folk. Sure, it is, but this shows that, seemingly, local temperatures magnify this effect.
So, what was this fascinating study?
This was conducted by Annika Stechemesser, et al. of the Potsdam Institute for Climate Impact Research by analysing over 4 billion tweets in the US using AI algorithms. From this they identified about 75 million English phrased hate tweets. They were then mapped to local temperatures and lo and behold a correlation was found.
What they found is that there is feel good window which corresponds to the minimum of hate tweets. That feel good window is between 12 and 21°C with the absolute minimum between 15 and 18°C. Temperatures either above or below, interestingly, led to an increase in hate tweets. Temperatures above 30°C are consistently linked to an increase in hate tweets across climate zones and socioeconomic differences including income, religious beliefs, or political preferences.
This is fascinating because it shows that local environmental conditions also impact hate behaviour – previously only considered as an attitude, personality, or belief problem. It also shows that changing climate dynamics with a global increase in extreme weather will likely also drive an increase in bad behaviour online and on social media.
Note also that this is not US specific with the same group of researchers also finding similar patterns in Europe.
This is important to note because this behaviour will likely occur in all social situations, in business and in society. We seem to have an optimal window and out of this things get, well, heated.
