Currently, an estimated 2.6 billion people – one-third of the world’s population – is living under some kind of lockdown or quarantine. This is arguably the largest psychological experiment ever conducted.
Unfortunately, we already have a good idea of its results
In short, and perhaps unsurprisingly, people who are quarantined are very likely to develop a wide range of symptoms of psychological stress and disorder, including low mood, insomnia, stress, anxiety, anger, irritability, emotional exhaustion, depression and post-traumatic stress symptoms. Low mood and irritability specifically stand out as being very common, the study notes.
