Nudges are subtle influences on behavior that steer people in a preferred direction without limiting options or significantly changing incentives. They work by designing choices to appeal to people's instincts and tendencies. Examples include putting healthy foods at eye level in a cafeteria or adding a fly graphic next to urinals in men's bathrooms to reduce spills. While nudges can encourage positive behaviors, they must be designed carefully and avoid becoming coercive or manipulative influences on choice.

3. A concept in behavioral science, political theory, and behavioral economics which
proposes positive reinforcement and indirect suggestions as ways to influence the
behavior and decision making of groups or individuals.
Nudge is a simple way to modify people behavior / relationship with an object and /
or environment by designing in incentives. It play’s off of peoples instinct's on a
conscious and / or subconscious level.
A nudge, as we will use the term, is any aspect of the choice architecture that alters
people's behavior in a predictable way without forbidding any options or significantly
changing their economic incentives..
NUDGE DEFINITIONS

4. Simply put, it’s a little push created by the
designer that makes the user think or do something they might
not instinctively do

5. NUDGES ARE NOT MANDATES
Putting fruit at eye level counts as a nudge.
Banning junk food does not.

7. PROBLEM
At Amsterdam's Schiphol Airport the men’s
bathroom needed cleaning all the time
because of “splashback”.

10. The fly acts as a target

11. WHY THE FLY?
The fly conjures up images of
something unsanitary, without
being scary

12. Initially reduced
“spillage” by up to 80%
Sphinx, the manufacturer, says
it reduces cleanup by 20% on
average

13. HOW NUDGES
WORK

14. CONSIDERATIONS WHEN DESIGNING A
NUDGE
1
Align incentives with desired behaviors, being careful to
avoid incentive conflicts
2 Provide clear, visible, and immediate feedback to
reinforce desired actions or mildly punish undesired
behaviors
3
Simplify and structure choices when decision
making parameters are complex
4
Make goals and performance status clearly visible

Low cost gym memberships
THE CHALLENGE
If everyone went to the gym who purchased a membership
there wouldn’t be enough room for anyone to work out

31. Most gyms try to nudge towards working out
more but they don’t

Uber uses an algorithm similar to Netflix’s auto play
feature, which automatically shows drivers their next
possible fare before they’re even done dropping off
their current rider
incentivizing them to drive more...

39. THE POWER
OF NUDGES

40. “Whenever I'm asked to
autograph a copy of “Nudge”
the book I sign it “Nudge for
good””
Unfortunately, that is meant as a plea,
not an expectation
- Richard Thaler

41. PRINCIPLES TO GUIDE THE USE OF NUDGES
1
All nudging should be transparent and never misleading
2 It should be as easy as possible to opt out of a
nudge, preferably with as little as one mouse click
3
There should be a good reason to believe that the
behavior being encouraged will improve the
welfare of those being nudged
