      A top public health expert says the evidence on use of #masks in public has become “so strong” it needs urgent attention. He says they could be key intervention to stop transmission. The MOH says they’re not needed. @NewshubNZ #COVID19nz #Masks4All #NZhttps://www.newshub.co.nz/home/new-zealand/2020/04/new-zealand-needs-to-urgently-look-at-wearing-masks-in-public-expert.html …

      I think the MoH position is more nuanced than this suggests. - Masks are *worse* than useless if they are handled incorrectly - Masks may well give a sense of security which is not justified and will compromise social distancing and hand hygiene

      There is absolutely no evidence that masks are worse than useless if handled incorrectly, and there is no evidence for false sense of security either currently, and from any past studies (this has been studied to death). Where are you getting this stuff?

      If these things have been studied to death you no doubt have any number of references you could post. Give me a few and I will be happy to revise my opinion if I think that is justified.

      Of course! Here's the link a paper with a section on false sense of security/risk compensation. It really has been studied to death! It comes up for every safety device. We have also just did a report to WHO on this, I will see if that can be made public. https://www.preprints.org/manuscript/202004.0203/v1 …pic.twitter.com/ZQSzXH3Dt4

      Thanks. I will read and inwardly digest. However, from a quick look at your screenshot I note the thrust of the argument is effectiveness at a *population* level for a particular mitigation. Covid-19 is different because risk compensation at an individual level can easily spread

      There isn't much evidence for risk compensation at the individual level, either. That said, it can no doubt occur but it has always been a second-order effect dwarfed by the benefits of the first order effect. And, there is reason to think the opposite: masks encourage vigilance.

      Replying to @zeynep @ChrisALee_NZ and

      Masks are a very visible signal of both something unusual and solidarity. So rather than risk compensation, which comes without empirical support, they would likely encourage more compliance with other measures. I'd say Hong Kong and Taiwan signal the latter.

          I've just retweeted to you a video which discusses debate around masks. I accept you have a good point of view on this but I baulk at comments like "without empirical support" (for a threat that's been around for a few months) and "likely to encourage" which has no more validity
