But one of Dr. Joe Schwarcz's radio listeners did jump to this conclusion after misinterpreting what had been said about a certain food colorant. Being on one end of a microphone and in front of television cameras for over twenty years has afforded some fascinating insight into the public’s perception of science.

This highly visual and entertaining presentation examines some serious as well as some frivolous experiences in dealing with the public and emphasizes the importance of fostering critical thinking. All are welcome!
