Transcript of Ioannidis, anthony salzburg 2015
- Why user experience matters
In the next hour or so…
- How you can make $300 million in 1 year…
- Good (and bad) practice examples
…and help a few people in the process
Do you use Facebook?(let me see hands, please!)
Have you looked at the privacy settings?(hands again, please!)
Have you changed any of the privacy settings?(Really?)
The less obvious way

The not-at-all obvious way
For 1 week, in 2012, Facebook hid certain
elements from 689,003 people’s news feed
The aim was to see whether this manipulation
would affect users’ emotions
No informed consent was requested from or
given by the participants
The not-at-all obvious way
The experiment showed that emotions
expressed by others on Facebook do
influence our own emotions
In other words:
Yes, Facebook can manipulate people’s
emotions by cherry-picking what it shows
on their news feed
And no, it doesn’t have to tell you
The ‘innocent’ way
Extra gentle for the
most sensitive skin.Start with ultra sensitive skin, add the chemicals
and moisture and you have diaper rash.

blend cotton padding provides extra thick,
gel-free protection for your baby.

And, of course, don’t forget our diaper ad…35

Does user testing work?
Air France flight 447 disappeared over the
Atlantic Ocean in July 2009

Does user testing work?
Old-style cockpit:
If pilot is pushing forward and co-pilot is
pulling back, their forces are averaged and
the stronger ‘wins’ 39
Does user testing work?
New-style cockpit uses joysticks – no need to
apply any significant force to fly the plane40
Now consider this:
• Pilot is pushing joystick forward
• Co-pilot is pulling joystick back
Should the plane...
• Go down (obey pilot – he knows best)
• Go up (obey co-pilot – pilot is drunk!)
• Average the two, as in the old design?
Airbus decided it makes sense to average
the two, just as the old design worked.
What the **** can go wrong with that?
It makes sense, right?
No need to test it, right?
228 dead
It was never tested with pilots…
42
Does user testing work?
02:13:40 (Pilot) “Climb… climb… climb…”
02:13:40 (Co-pilot) “But I’ve had the stick back the whole time!”
02:13:42 (Engineer) “No, no, no… Don’t climb… no, no.”
02:13:43 (Pilot) “Descend… Give me the controls… Give me the controls!”
To gain speed, the plane should have been in a descend.
The pilot had no idea the co-pilot was pulling it up...
It was never tested with pilots, because ‘it made sense’.

Google’s ‘50 shades of blue’
In Google UK's former MD Dan Cobley’s
own words:
46
Seven years ago, Google launched ads on Gmail. In our search we have ads
on the side, little blue links that go to other websites: we had the same thing
on gmail. But we recognised that the shades of blue in those two products
were slightly different.
We ran ‘1% experiments’, showing 1% of users one blue, and another
experiment showing 1% another blue. And actually, to make sure we covered
all our bases, we ran forty other experiments showing all the shades of blue
you could possibly imagine.
“
Google’s ‘50 shades of blue’
47
And we saw which shades of blue people liked the most, demonstrated by
how much they clicked on them. As a result we learned that a slightly purpler
shade of blue was more conducive to clicking than a slightly greener shade
of blue.
But the implications of that for us, given the scale of our business, was that
we made an extra $200m a year in ad revenue.
“
OKCupid’s ‘50 shades of gray’
48
OKCupid run some experiments on their users:
• removed text from users' profiles
• removed photos
• told some users they were an excellent
match, when they were only a 30% match
and vice-versa
It all started years ago
50
First large-scale A/B experiments run by
direct marketing (junk mail) companies
A mailshot can go to 10 million people with
5 million different permutations
• Stuffing an envelope with gifts or physical items makes
people more likely to open it
• Thicker paper can make a letter feel more important, so
recipients are likely to give it better attention
• Delivering garden furniture mailshots during sunny spells
resulted in 34% higher sales of outdoor products (IKEA)
P.S: Did you know?
51
• Even the use of a “P.S.”, in which the recipient is prompted to
get in touch with the company and make a purchase has been
tested, and is now considered best practice
But,
What’s an easy way to make $200 million in 1 year?
I promised to show you
how to make $300 million…
Analytics
Every time you visit a website, we know
• How much time you spend on it
• Where you came from
• Where you’re off to
• What you are interested in
• How old you are
• Where you’re from
• What you did last summer
54
Analytics
45% of customers had multiple accounts in
the system, some as many as
160,000 forgotten password requests / day
75% of these never tried to complete
the purchase once requested

57
Analytics
After the change:
45% increase in purchases
An extra $15 million in the first month
$300,000,000 in the first year

Solving life’s little problems
A problem for busy airports:
- men’s aiming is very poor when using urinals
Schiphol Airport in Amsterdam found a solution:
- signposting

Progressive disclosure
72
“ An interaction design technique that sequences
information across several sections, in order to help
maintain the focus of a user's attention by reducing
clutter, confusion, and cognitive workload. By disclosing
information progressively, you reveal only the essentials
and help the user manage the complexity of feature-rich
sites or applications.

Why the different behaviour?
Social media has taught us that it’s OK to do
‘creepy’ things online (follow, like, poke...)
‘Everybody’ does it, so it’s socially acceptable
We are influenced by what our peers do
‘Social’ sites take advantage of this
A good example
Showing this message
on Facebook drove
about 60,000 extra
votes in the 2010 US
Congressional
elections
Showing this one
drove a further
282,000 votes
A bad example
Facebook unlawfully used the names and profile
pictures of its users, including minors, to
advertise without obtaining their consent
1 class action lawsuit settled ($20 million)
1 more in Canada, recently ruled to be
outside the local Courts’ jurisdiction
In a student survey…
1. How happy are you?
2. How often do you go on a date?
If asked in this order
- correlation is only 0.11
If asked in the reverse order
- correlation jumps to 0.62!

Choice Architecture
We have the power to frame questions in a
way that manipulates answers
We have the power to nudge people to the
right (or wrong) direction
A force for good or evil? (Discuss)
81
Choice Architecture
How much would you like to donate?
- $10
- $25
- $100
- $500
- Other amount
- $50
- $100
- $500
- $1,000
- Other amount

Choice Architecture
Simply by rearranging food in a school
cafeteria, researchers were able to increase or
decrease consumption of particular foods by
25%
(We do that every day, when you visit your favourite websites
– we just don’t tell you)
83
Getting people to donate
Research in South Korea showed that about
89% of people wanted to donate
In reality only 0.9% actually did
How can we get more people to donate?
86
Getting people to donate
Minewater has two barcodes:
• Scan one, and you'll be charged $1
• Scan the other, you'll donate 10 cents
