I think many scientists opt to stay in the background and, to be fair, they’re busy doing research (or at least trying to do research). The April 22nd International March for Science might provide an opportunity to come forward, but their voice is in danger of sounding entitled if it isn’t accompanied by support from members of the public. They are the ultimate funders and benefactors of all research and if they do not perceive value from that, then we’ll continue to flounder.
I should also note that this is not a Canadian phenomenon. Other advanced countries have also let public sector research atrophy while emerging countries have high single to double-digit annual increases in investments. They’ve got a lot of catching up to do, but they understand the benefits.
