Hardly an ardent fan of EC science, is he?
Speaking as a scientist, and being married to a scientist, I can offer our personal take on this.
We scientists are generally an international-looking collaborative bunch, and our pre-eminent concern in choosing where to work and other academics to collaborate with is: will this be good for the science? That's how we end up working, obtaining funding, and collaborating with people, all over the world.
What we don't think will be good for the science is the funding being - at a minimum - thrown into massive uncertainty, fellow academics feeling equally uncertain and even unwelcome, and a general climate in which "experts", "liberal elites" and "citizens of the world" are explicitly identified as de facto enemies set against "ordinary people".
Having spoken to many colleagues since the referendum, we have heard many examples (yes, anecdotes, sorry) of people planning to move away (including British scientists), people who were planning to move here deciding not to (including British scientists who might have returned), and general difficulty in recruiting scientists not just from the EU but various other countries too (including people pulling out in the middle of recruitment negotiations). Not all of these people will be moving to the EU, so yes you can shout "Hah! So much for EU science!" but since we're all about how important the UK is above all, the main point is that they won't be here.
But anyway - what do scientists know?
