11. THEY’RE PROOF THAT OUR BRAINS SOMETIMES MAKE IRRATIONAL
JUGEMENT MISTAKES

CASE STUDY:
DAN ARIELY –
PRICING THE ECONOMIST
Predictably irrational, 2007
13. TWO GROUPS WERE OFFERERED TO SUBSCRIBE TO ‘THE ECONOMIST’
… BUT WERE SHOWN DIFFERENT SUBSCRIPTION FORMS
GROUP 1 GOT THIS FORM: GROUP 2 GOT THIS FORM:
14. TWO GROUPS WERE OFFERERED TO SUBSCRIBE TO ‘THE ECONOMIST’
… BUT WERE SHOWN DIFFERENT SUBSCRIPTION FORMS
GROUP 1 GOT THIS FORM: GROUP 2 GOT THIS FORM:
THREE OPTIONS
ECONOMIST.COM SUBSCRIPTION 59$
PRINT SUBSCRIPTION 125$
PRINT & WEB SUBSCRIPTION 125$
ONLY TWO OPTIONS
ECONOMIST.COM SUBSCRIPTION 59$
PRINT & WEB SUBSCRIPTION 125$
16. GROUP 1
84% CHOSE THE MORE EXPENSIVE
PRINT & WEB SUBSCRIPTION
GROUP 2
ONLY 32% CHOSE THE MORE EXPENSIVE
PRINT & WEB SUBSCRIPTION
RESULTS
17. EXPLANATION
GROUP 1
‘THE ECONOMIST’ ADDED THE EXPENSIVE 125$ “PRINT ONLY” OPTION
FOR GROUP 1 TO COMPARE AGAINST
IT MADE THE 125$ “PRINT+WEB” APPEAR AS A GOOD DEAL
THEREFORE SUBJECTS “FORGOT” THE CHEAP 59$ OPTION
18. EXPLANATION
GROUP 2
WHEREAS GROUP 2 WEREN’T BIASED BY THE BAD DEAL
THEREFORE THEY MADE A MORE RATIONAL CHOICE
19. CONCLUSION
THIS IS CALLED ANCHORING
THE TENDENCY TO RELY ON & BE INFLUENCED BY A KEY PIECE OF INFORMATION
(« THE ANCHOR ») WHEN MAKING DECISIONS
34. BECAUSE WE ARE IN A PERMANENT CONFLICT WITH OURSELVES
CONFLICT
COGNITIVE
DISSONANCE
=
NEED TO
POST-RATIONALISE
« I said I would start
exercising »
« I’ll start next Monday»
«You only live once! »
« Today is a special day »
« But I really want to
eat ALL THIS »
35. BECAUSE WE THINK THINGS WORK TH IS WAY

WHEN THEY ACTUALLY WORK THIS WAY
39. THE ILLUSORY CORRELATION BIAS
Creating illogical correlation between two events
THE EXPERIMENT
Chapman & Chapman (1967) showed students a list of 12 pairs of words based on 7
different words. Each pair only appeared once in the list.
They were asked how many times each pair had appeared:
IN REAL LIFE:
• PowerPoint seems
to crash only when
I’m working on a
very important deck
• Traffic lights change
to red when I’m in a
hurry

Pairs that seemed correlated
(e.g. tiger+lion, egg+bacon) were
mentioned more frequently -
even though they appeared
only once
40. THE AVAILABILITY HEURISTIC
Tending to overestimate the importance of an event/fact if we remember it
THE EXPERIMENT
Tversky & Kahneman, 1974
IN REAL LIFE
- We are more afraid to die
in a plane crash than of
an asthma attack,
because we hear more
about plane crashes on
TV
- We overestimate food
scandals because we
remember most the few
ones involving our
favorite fast-food chains
If a random word is taken from an English text, is it more likely that the word will start with K
or that it will have K as the third letter?"
<
>
70% said start with a K 30% said K as the third letter
Most English-speaking people were immediately able to think of many words that start with the letter
K (kangaroo, kitchen, kale), but it took a more concentrated effort to think of any words that had K as
the third letter (acknowledge, ask).
Results indicated that participants overestimated the number of words that started with the letter K:
In reality, there are twice as many words that have K as the third letter than words starting with K !
41. THE CONFIRMATION BIAS
Interpreting information in a way that confirms our preconceptions
Discrediting information that does not support our views
IN REAL LIFE
- Smokers believe studies
showing smoking isn’t
that risky
- We read and remember
more articles about ideas
we agree with
- When it comes to politics,
we think the other camp
is ALWAYS WRONG

45. BY LEVERAGING THEM IN THE RIGHT WAY,
IT’S POSSIBLE TO INFLUENCE USERS’
DECISIONS AND ACTIONS
46. WHAT TO LEVERAGE ?
1. LIMIT CHOICE
2. LEVERAGE SOCIAL PROOF
3. LEVERAGE RECIPROCATION
4. USE THE SCARCITY PRINCIPLE
5. LEVERAGE COMMITMENT
6. SET UP A PROGRESSION DYNAMIC
7. TALK ABOUT SEX (OH YEAH BABY!)
Inspired by “Behavioural economics and digital marketing”
by Vyshnavi Doss , 2012
47. 1. LIMIT CHOICE
Instead of implementing every single social network
plug-ins to encourage content sharing, use only the ones
relevant – e.g. Facebook & Twitter first on Mashable
In a supermarket, study shows:
24 types of beers:
3% purchase
9 types of beers:
30% purchase
48. 2. LEVERAGE SOCIAL PROOF
Amazon set up the standards of cross-sell
based on other customers purchase
Linkedin emailing strategy is based on social
proof. It invites you to do what your professional
network has also done
49. 3. LEVERAGE RECIPROCATION
RockCorps produces some of the hottest gigs in the
music calendar. Here’s the deal: You can’t buy a ticket.
You can’t win a ticket. You have to earn a ticket. The
user has to give 4 hours of his/her time to the
RockCorps community to get a concert ticket in return.
One of the things that prevents lead gen content from going viral is that
anyone wanting to access it has to fill out a form. Pay with a Tweet is a
service that lets visitors access lead gen content without having to “pay”
for it by giving up any personal information on a form - all they have to
do is share it with their own networks or Facebook, Twitter or LinkedIn.
50. 4. USE THE SCARCITY PRINCIPLE
“The last
reservation at
this price
happened five
minutes ago”
“Hurry up, only
1 seat left at
this price”
51. How to make you quit smoking?
ECONOMICS:
CONSUMERS ARE RATIONAL
PSYCHOLOGY/ADVERTISING
PEOPLE REACT TO THEIR
EMOTIONS
BEHAVIOURAL ECONOMICS:
PEOPLE ARE PREDICTABILY
IRRATIONAL
Prohibitive pricing for
cigarettes
Provoke fear and guilt Pledge to give up smoking in a
digital public place eg. Facebook
5. LEVERAGE COMMITMENT
52. 6. SET UP A PROGRESSION DYNAMIC
VS
Regular one piece form with many
boxes in a single interface
The goal-gradient effect: the smaller the goal, the
closer and more reachable it seems

56. We have an “old” brain: the reptilian complex. It used to be responsible for instinctive behaviours to ensure
human survival. The reptilian complex basically asks itself three questions:
CAN I EAT IT?
WHY?
CAN I HAVE SEX WITH IT?
CAN I DIE BECAUSE OF IT?
57. WHY?
We have an “old” brain: the reptilian complex. It used to be responsible for instinctive behaviours to ensure
human survival. The reptilian complex basically asks itself three questions:
THAT’S WHY WE ARE STILL INEVITABLY
ATTRACTED TO PICTURES OF SEXY
MEN/WOMEN,
MOUTH-WATERING FOOD
OR DANGERS/ACCIDENTS…
IT’S OUR OLD BRAIN REACTING
58. OK, THIS LAST EXAMPLE HAS NOTHING TO DO
WITH DIGITAL MARKETING…
61. NOPE, THE DECISIONS WE MAKE ARE NOT RATIONAL
THIS IS NOT A SCIENCE, IT’S JUST AN ALTERNATIVE WAY TO ANALYSE CONSUMER
BEHAVIOUR
AND CONSUMER BEHAVIOUR IS A BIG CHALLENGE FOR THOSE WORKING
TO BUILD USER-FRIENDLY EXPERIENCES ONLINE
Plus tu t’approches de l’objectif plus tu t’actives pour l‘atteindre, d’ou l’interet de montrer la progression: the goal gradient effect
Plus l’objectif est proche, plus les utilisateurs sont motivés, surtout si ils voient leur progression (visuellement sur une interface)
----- Notes de la réunion (15/07/14 10:49) -----
PLUS LES OBJECTIFS PARAISSENT PETITS PLUS ILS SEMBLENT ATTEIGNABLES
