This is a companion question to Why do most scientists think Brexit is bad for British science?. Based on this meta discussion, it was suggested that I ask a new question about potential upsides of Brexit...
From the answers to that question about Brexit, it sounds like there are no upsides to British science. However, there are still roughly 12% of UK researchers who think the UK should exit the EU. It seems that these 12% must see something positive from Brexit, otherwise they would not be voting to leave.
What could these positives be? Or are there no positives, and they are just more optimistic that the UK government will provide the political support to let British science emerge unscathed and / or they think the gains elsewhere outweigh the losses?
Only thing I've seen about this is Royal Society president Venkatraman Ramakrishnan saying:
Will Brexit open up any new opportunities for UK science? Are there burdensome EU regulations you’ll be glad to see go? Will collaboration with scientists in non-EU countries, like the US or China, become easier? Will tranches of non-EU funding become accessible?
The only thing I can say is that if you have new technologies and you need to make regulations where current regulations don’t exist, then it’s easier for a single country. Britain is very rational about balancing risks and benefits. Its easier for one country to move fast. This is a sort of theoretical, possibly marginal benefit. Whereas the actual risks and drawbacks of Brexit are much more real and immediate.
However this sounds extremely marginal. Unless these 12% of UK researchers know in advance that they're going to come up with groundbreaking new technologies for which current regulations don't exist, it's hard to believe that 12% of UK researchers would vote to leave for this reason.
I am interested in all positives, short-term or long-term.
