    It's pretty clear that masks don't *decrease* social distancing, despite concerns about a "false sense of security" leading to reckless behavior. Risk compensation arguments are generally baseless and interfere with good public health. https://www.theatlantic.com/ideas/archive/2020/05/no-one-telling-americans-how-reopen-their-lives/612172/ …https://twitter.com/DiseaseEcology/status/1272587956172148737 …

    Do masks increase social distancing? 2 papers suggest that wearing a mask increases social distancing. This would be great if it were true as it would add to the protective effects of wearing masks. Unfortunately neither paper is convincing that this will reduce transmission.

        For those of us who do HIV/STIs, the number of parallels between the mask and the condom are hard to keep track of. ie, all things being equal, most would prefer not to have one on, less intimacy, people stigmatize those that dont use (#truvadawhores), access not universal, etc.

        Agreed! Although probably not much overlap between #truvadawhores and mask liberationists...

        That seems like a somewhat different but also important question, about how reopening decisions are being justified vs. potential impact of masks on individual-level behavior.
