In the context of the exponential growth of the pandemic, everyone has to make some decision: When there is a world shortage of material (screening tests, masks, respirators and vaccine), societal measures are crucial to contain an epidemic. In this context, psychological and behavioral parameters become directly relevant to public health, but can also subject us to a philosophical argument as in Pascal's wager.
To be masked or not to be masked during the Covid-19 Pandemic appears then as a social and psychological double bind.
The subject of protective masks, be they professionally or handmade, is omnipresent and concerns healthcare professionals as well as the general population [1,2].
So should you wear one?
In some countries, wearing a mask was made mandatory and you are not expected to choose but only to comply.
But in the vast majority of the rest of the world, especially when considering de-confinement, wearing a mask (or not) remains a social and psychological matter, sometimes to a schizophrenogenic extent:
• If you wear a protective mask, some people will be suspicious of you as it could mean that you have the virus, while depending on their psychological reasoning, others will believe that you are trying to protect yourself and/or your environment.
• If you don't wear a protective mask, you might be perceived as a public menace, especially if you are a healthcare worker.
This means that in both situations, you are partially wrong as you either generate or maintain Covid-phobia and/or Covid-chondria. You can't win!
The same duality applies to healthcare workers: They can be acknowledged (and applauded) as heroes who are saving lives, or they can be attacked by people who consider them as contamination agents.
This is a typical case of "double bind" as per the Palo Alto studies which demonstrated how a schizophrenic patient is often subjected to dual constraints [3,4].
On the positive side, while currently waiting for a vaccine, the world economy, as well as people of good will attempt to produce as many masks as possible; as long as they are effective against coronavirus.
The decision to wear (or not) the mask goes the same way as Pascal's wager [5]: Believing in it is better than not believing in it, so wearing the mask is better than denying its benefit.
