Chilling Trust
Why Warmer Weather Might Make You Less Trusting
Ever felt like a hot day makes you a little grumpier, while a cold snap has you cozying up with friends? Well, science suggests that temperature might not just affect our mood but also how much we trust strangers. A 2025 study by Xu et al. explores this idea, asking: could the weather outside be influencing the trust inside?
The Unexpected Link Between Trust and Temperature
Their team of researchers in China crunched the numbers on data from nearly 27,000 people across the country. The findings are chilling (sorry).
People living in regions with more comfortable temperatures (around 22°C) were less likely to trust strangers than those in more extreme climates.
Interestingly, the study also found that temperature plays a more significant role in predicting trust than some traditional demographic factors, like gender or population size. This suggests that something as fundamental as climate might shape the state of trust in ways that we — or at least I — hadn’t fully appreciated before.
Now, that result might seem a bit surprising. After all, shouldn’t pleasant weather make us more friendly? If the weather is nice, won’t I be in a good mood? And if I’m in a good mood, won’t I be…
