Lesson 9-2

Also in Sweden,

there was an experiment to encourage people

to throw their trash away properly.

A loudspeaker and sensor

were placed inside an ordinary trash can.

When you dropped something into the can,

it made a long falling sound

as if the bottom was deep understand.

People loved it

and because of the little nudge,

the streets became much cleaner.

The Indian city of Mumbai

is known as "the honking capital of the world."

Mumbai drivers are always honking.

They even honk at traffic lights.

To encourage better manners,

police have come up with

the "Honk More, Wait More" system.

The system resets the red signal

every time the sound of horns

goes above 85 decibels:

a little nudge to be patient.

We can also find examples of nudges

in schools.

Many schools in the U.S.

use a nudge in their cafeterias

to encourage healthy choices.

Research shows

that if you put fruit in an attractive bowl

at the start of the line,

more students make the healthy choice
