Apparently self-isolation has never been law in Scotland, just advice.

I’m pretty certain that at least during the original wave the requirement to isolate if a confirmed positive was a legal requirement. I can’t be bothered trawling through the old SIs to check. The requirement to isolate as a named contact was never law AFAIK.
I’m less convinced than ever that mask wearing has any impact.
Comparing infection rates between Scotland and England, there is no obvious benefit (one could almost argue it’s a negative)
I have to say whilst I’ve been an avid mask wearer and continue to do so, I’m inclined to agree with Scotroutes. We effectively have england as a massive control group at the moment (I was there last week and virtually nobody was wearing masks in any setting I saw). I know plenty of positive cases, including school age people – but amateur epidemiology suggest they probably didn’t get infected at school (e.g. the whole class didn’t get sick but everyone at the party did – which was made up of multiple classes!).
