Barbara Vis on heuristics

Politicians are humans, and humans do not always reason syllogistically from premises to conclusions. The problem is amplified when political decisions have to be made fast, under conditions of uncertainty, with either not enough information or far too much.

That's where heuristics come in -- and Professor Barbara Vis is here to help us understand when they are used, what their impacts can be, and how we should take that into account when delivering science advice.
