Every year, millions of people face a mystery: where do socks disappear from the wash?
It seems like a small thing, but scientists have been trying to find an explanation for it for decades.
It turns out that the reason is not forgetfulness or the tricks of brownies. Everything is much more prosaic - and at the same time stranger.
Research has shown that socks are often "lost" due to the design of washing machines, which trap them in crevices in the drum or drain filters.
But how then to explain the disappearance of paired socks in different places? This is where psychology comes into play: our brains tend to remember losses, but ignore cases when things are found.
In addition, statistics show that socks of certain colors and sizes are more likely to disappear.
But there are also more exotic versions: for example, the theory that some textile fibers break down into microplastics and end up in the sewer.
Believe it or not, the solution to the problem is simpler than it seems.
