If you're asking me, the answer is yes. I've looked at various countries. I've looked at the States. I've looked at children's drawing laureates. I've looked at the City of Toronto. The City of Victoria did a wonderful one for Canada 150. They actually had two indigenous visual artist laureates to celebrate Canada 150.
Yes, I've looked at many and looked at both the tangible effects and the longer-term and maybe not as immediately tangible effects, and they're very strong.
There is one laureate in Britain who was the children's laureate, and he drew. He got kids reading. He got kids drawing. He got an engagement, and some school divisions that monitored it recognized an improvement in the kids' learning abilities.
