Without Facebook Connect:
Conversions ↑ 3%
Revenues ↑ $10,000
“The a/b test just shows, that THIS
version of form is bad, not that
Facebook login reduces sales.”
Jakub Karlec - Intuition over analytics
Misinterpretation of analytical
data is a common mistake
Not the tools,
but the people matter
Biases and assumptions
“A person can make himself happy, or
miserable, regardless of what is
actually happening outside.”
— Mihaly Csikszentmihalyi
Never trust anyone with
a mortgage

Can you measure the impact of
shutting display advertising
down?
Long term effects

Benefits of intuition–driven
design
You will never change history, if
you rely solely on analytics data.
“True leaders have the ability to make
the right decision even with limited
information.”
— Warren Bennis
It's way cheaper and faster
Waiting for relevant and
statistically significant data can do
more harm than living without
analytics at all.
The story of Marissa Mayer
Jakub Karlec - Intuition over analytics
When designers wanted to
change the blue colour on
Google's homepage, they had to
do multivariate testing of 41
shades of blue to see which one
performs best.
"[…] data eventually becomes
a crutch for every decision, paralyzing
the company and preventing it from
making any daring design decisions."
– Doug Bowman
“We let the math and the data govern
how things look and feel.”
— Marissa Mayer
Jakub Karlec - Intuition over analytics
Year after Mayer took over Yahoo,
the company’s stock price was up
100 percent.
“True leaders have the ability to make
the right decision even with limited
information.”
— Warren Bennis
