Electric shock therapy has supposedly been used to teach rats how to trade shares, apparently resulting in returns that beat those generated by some of the world's best fund managers.
According to Enlightenment Economics, the experiment was conducted by Michael Marcovici and features in the book Art and Economy. The project involved playing rats ticker tape noises representing share movements, then rewarded them with food for guessing future movements right -- and punished them with electric shocks when their gamble on ASOS plummeted by another 10 per cent.
The fact that the word "art" is involved and there's a quite clearly signposted "bankers = no better than rats" metaphor in here, leads us to suspect it might not be a real thing. [Business Insider]
