The Swedes have taken this line as well, saying they 'trust' their citizens.
I think it's not very rational, and also borderline chauvinist for people to say this.
First - what evidence does anyone have that Swiss/Swedes or anyone for that matter are consistently behaving in one way or another that is more 'responsible' or 'sensible' than others?
I don't see any evidence.
A nationalist self-image of responsibility doesn't count as Science, and neither does a few images of fools on a Florida beach as it's all rather anecdotal.
The other issue is that policy is material, not just 'responsibility' - for example - we know from Wuhan that restaurants and other places are a vector for transmission. So it doesn't matter if certain groups are 'behaving responsibly' so much - if they are going to restaurants, hotels, tanning salons etc. - even that otherwise 'responsible behaviour' inside the scope of 'following the rules' that is actually causing transmission.
Given all of the variables we have to look at, the last place I think we can infer variation is with regards to who is 'being reasonable' by some arbitrary definition.
That said - it would be really good to look at different nations varying policies and see how it works.
It could be that <5 people is 'enough' to keep the R1 below 1, though there are obviously other factors. Maybe the Swiss have found the 'sweet spot'?
In Canada, the problem was stopped, but there's already a continued second wave in long-term care homes, it's possible those are structured differently in Canada than other countries.
