Impact may cause Brain Drain?

According to the UCU, a third of academics they questioned said they'd consider leaving the UK if the government's impact proposals go ahead. Over two thirds of them did not support the proposals. More detail on their survey is available here.

Whilst we know impact is generally unpopular amongst academics, I think the UCU poll should be treated with a pinch of salt. UCU are, after all, the instigators of a 14,000 strong petition against impact, so they are not exactly an impartial actor in this. But interesting nonetheless.
