We recently did an update to a survey of our scientists, particularly on the muzzling of scientists. Although when we took it in 2013 some 90% of our members felt that they were being muzzled, that number is down to a little over 50%. However, a little over 50% of scientists still feel that they are being muzzled. Despite the declarations that they can now speak openly about their work, they still can't really speak openly about their concerns.
On October 4th, 2018. See this statement in context.
