But for those people who are perfectly capable of wearing a mask, but still decide not to wear one, it turns out their controversial decisions might run a lot deeper than the frustrating rhetoric around whether or not a mask is “comfortable” or “convenient” – in fact, it could reveal key details about the inner workings of their psychology.

“The choices we make regarding what to wear – or not wear – signal to the outside world important information about who we are, according to Social Identity Theory,” explains Dr Meg Arroll, chartered psychologist with Healthspan.

Arroll continues: “This classic psychological theory states that aspects of our identity arise from the groups which people are, or want to be, a part of. Therefore, if we observe members of a desired group not wearing face masks, we may replicate this in order to be seen as part of this group – for instance a powerful political leader.

“When it comes to everyday clothing, this notion is not surprising, but in the case of a mask which may make the difference between life and death, those on the other side of the fence might find the refusal to wear this protective layer rather perplexing or offensive.
