This year’s economics Nobel Prize winner Richard Thaler wrote a trivia-lover’s fantasy book called Nudge, in which he described how tiny prompts can alter human behaviour.

BBC has a nifty list here.

In the Indian context, a fine example of Thaler’s behavioural economics theory at play are tiles of gods and goddesses being installed on walls to prevent men from peeing.

More effective than warning those who unzip that you are “worse than dogs”.

The question, though, is: did desi genius come up with this idea on its own, or was it subconsciously nudged into it by Thaler?
