16. Traps
we
fall
into
• Narra)ve
fallacy
• Confirma)on
bias
17. Narrative Fallacy
Humans
have
trouble
looking
sequences
of
facts
without
weaving
an
explana)on
into
them,
or,
equivalently,
forcing
a
logical
link,
an
arrow
of
rela)onship
upon
them.
Explana)ons
bind
facts
together.
They
make
them
all
the
more
easily
remembered;
they
help
them
make
more
sense.
This
goes
wrong
is
when
it
increases
our
impression
of
understanding.

20. Confirmation Bias
People
tend
to
favor
informa)on
that
confirms
their
beliefs
or
hypotheses.
People
display
this
bias
when
they
gather
or
remember
informa)on
selec)vely,
or
when
they
interpret
it
in
a
biased
way.
For
example,
in
reading
about
current
poli)cal
issues,
people
usually
prefer
sources
that
affirm
their
exis)ng
aWtudes.
They
also
tend
to
interpret
ambiguous
evidence
as
suppor)ng
their
exis)ng
posi)on.

30. What
did
we
learn?
• Find
out
what
doesn’t
work
– Then,
stop
doing
that
• Start
with
failure
modes
• Be
vigilant
about
not
falling
into
narra)ve
fallacies
• Posi)oning
statement
can
determine
what
needs
tes)ng
• Use
conclusive
tests
without
confirma)on
bias
