Nudge Design Definition
“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. To count as a mere nudge,
the intervention must be easy and cheap to avoid.”

morning. It is usually $2.50. Today, they raised the
price and it is now $3 for your morning coffee.

Framing Definition
Judging options as losses or gains relative
to some perceived starting reference point
12. Nudge Design Amanda Bentley
Design Tip
• Encourage positive behavior by emphasizing
associated gains rather than associated losses
• To discourage a behavior, make it seem
undesirable by emphasizing associated losses
13. Nudge Design Amanda Bentley
Default Bias Example
Do you all sit in assigned seats? No? Are you
sitting in the same seat everyday anyway?
How much do you tend to tip waiters?
14. Nudge Design Amanda Bentley
Default Bias Definition
The tendency to go along with an existing
situation or selection rather than taking action
to change it; therefore, more likely to choose
default setting
15. Nudge Design Amanda Bentley
Design Tip
• To encourage a specific option, make it the
default
• Likewise, to discourage a specific option, don’t
make it the default
16. Nudge Design Amanda Bentley
Present Bias Example
Who online shops regularly?
Do you wait to buy something until it goes on sale?
Have you ever spent extra on expedited shipping
when regular shipping would only take 4-5 days?
17. Nudge Design Amanda Bentley
Present Bias Definition
Time plays a big role in decision making; people
generally prefer gains that happen in the present
(instant gratification) to gains that occur in the
future (time discounting)
18. Nudge Design Amanda Bentley
Design Tip
• To encourage a behavior where the positive
outcomes are delayed, introduce present
benefits to make the desired outcome more
appealing
• To encourage a behavior usually associated with
a loss, delay losses so they occur in the future
