Look at what we've done to the innocent and young

Try this out:

(1) Wear a colourful shirt/top.

(2) Walk on a crowded street and look at the colours of the shirts/tops of other people.

(3) Tell a friend who is walking with you the colour of the shirt/top of the nearest person.

(4) Now, think of the colour of your shirt/top.

(5) Repeat step 3 immediately.

Let me know how it goes. If you're like me, you'll blurt out your shirts' colour.

There's a behavioural economics lesson in this.
