good evening and I would like to start from the fact
we live in a hyper-connected world
thanks to the advent of the internet and the
new technologies we are able to
communicate with people in every part of the
world and thanks to social networks
we can communicate without any kind of
temporal and spatial barriers e
what we have observed in the
last years is a real change
of paradigm
we have moved from the old context
that represented by the media
traditional television the radio the
print where the information before
reaching the public came in some
way mediated by experts in the sector
from journalists to publishers the new
context that we move in all of us
currently instead strongly
disintermediate anyone can go
online and not just access one
vastness of contents but above all
help create new ones and there is not
again only the disintermediation but
just the structure of this new one
information space in which we move
which is characterized by a presence
continuous and constant new content
in which we can often also lose the
our points of reference and the times
they are always shorter than they are almost
then canceled in a context of
this type our ability to
reflection analysis are hard
put to the test and cognitive mechanisms
we all use ourselves
habitually in our life
daily
so it’s about yesterday ‘s shortcuts
of heuristics then we put them in place
even in such a context only
that the moment we pass
from the complex to the simple we can
make mistakes
here I have just quoted a famous sculptor
constantin bronx that says simplicity
it is a resolved complexity
but let’s see what happens in the moment in
in implementing these mechanisms
our mind can deceive you
one of the cognitive mechanisms
fundamental that I will talk about is the
confirmation byas that we could translate
as byas confirms the prejudice of
that is, confirms that human tendency which
so it belongs to anyone who a
anyone who makes us select the
Information look for information
interpret them in a way that is
consistent with our system of
beliefs that we have rooted
so with ours with our whole
of our set of values with the
our vision of the world and the
confirmation myers together with others
mechanisms that play a role in the
social contagion then in the way
one influences one another
they are key elements to enable us to
better understand the phenomenon of
disinformation and also
information in particular i
eyes I speak to you about the polarization of
group that is one of the most phenomena
interesting point of view
of social influence is the phenomenon that
occurs when individuals who
they share a same vision of the world
so that they have opinions
tendentially similar in the moment in
they argue they strengthen their own
opinions will eventually come to have
a more extreme opinion from that one
the one from which they had left and another
experiment interesting experiment
of only 1955 monash in which
eight participants were asked
participants of which in reality one
only it was the subject was asked
to indicate which of the three lines in the
right card correspond to the
line on the left card now in the
first two rounds all the participants
they gave the correct answer which is that
also quite obvious in the third round
some of the participants who did
part of the experiment starts instead
go wrong answers then a
choose one of the two lines that most
short the longer one in this case the
true subject of the experiment could
change your choice
well in the first two rounds the rate of
error was about one percent in the
third round of almost 37 percent
so actually in front of the
pressure in the group we tend to
abandon the evidence of the same
our of our senses now the
combination of these mechanisms with the
hyperconnected context from which they are
matches makes this environment
particularly favorable to
diffusion of viral phenomena ai
digital wolf eyes
here I show you a map that is present in the
global risk report of 2013 of the world
economic forum
therefore in this map are indicated
the greatest geo political risks e
technology and you can see that the
massey digital bees information is
practically at the center of the
constellation
this is because disinformation
mass digital can be
particularly dangerous because it can
to negatively influence opinion
public and can have influences
negative in the real world
I ‘ll give you some examples here
the case for example jaden fifteen that is
a military exercise that you are
held in the United States and that was
initially perceived on the internet as
an attempt to obama a plot
impose martial law on states
united
to the point that the governor of the texas
Renga Bush decided to alert her
national guard
if instead of the throat after death
of two people for drinking water
salted the world organization of the
health has had to reiterate that all
hypothetical alternative cures that
they circulated online and also circulated
via whatsapp they were completely
unreliable and very dangerous or still
the case of the delegation of the ds in
South Africa for inadequate policies
sanitary there were more than 300,000
dead that could have been avoided for ds
but surely the strong strong presence
presence of the negationists has exacerbated
this situation the negationists
they claim that inoffensive Russia cai
that antiretroviral drugs cause the
disease rather than cure it then in
Italy we are not exempt
this is one of the buffaloes that
become more viral in Italy where you
he speaks of a hypothetical bill
presented by the senator to hold us for
finance funds for parliamentarians
that they were in crisis at the end of theirs
mandate
this hoax, in short, gone viral in
text there are several inaccuracies
for example the total number of
senators and different from that
expected by our constitution
yet the text went viral again
today on the senatur page, let us
there are insults from many users
Italians despite the senatur comes to us
it does not exist and is a pure character
fantasy and therefore what we have
done us as a research group is done
to try to analyze these phenomena
that are social phenomena but in a manner
quantitative then using
tools that came
from the computer science then
in the information technology that from the statistics e
then putting different together
tools to exploit all traces
digital ones that users leave on
social media on social media and in
we have dealt with it first
place to study the role of the
confirmation bias
in the mechanisms in the diffusion of the
information
so for the methodology we have it
analyzed the behavior of users in
two different and contrasting narratives
scientific fiction and narrative
pseudo scientific we have collected i
data both we have collected 2 dataset of
different faith an italian dataset with
about one million users went to 7
equivalent for the United States with
about 5 with 54 million users
both datasets cover an arc
timeframe of five years from 2010 to
2014 and the first observation the first
result was that we tried
empirically the existence of the
so-called eco chamber what are the
consciences are in the groups of bubbles in
which users with the same vision of the
world are grouped and continue to
discuss and reinforce your own
opinions
we have seen that the spread of the
information is guided by the confirmation
buyers and is guided by homophilia then
from the tendency to look for individuals
very similar to us and therefore users
they tend to form these groups
polarized and we then studied which
it was the feeling of the users
involved in these groups
these are data for the Italian dataset
and here we can see that in general the
user trend is negative there is the
average user feeling
in the social network approach it is negative
but the interesting fact is that in
when we consider users
polarized ie users who
most of them concentrate
activity
one of the two categories then in this
case you can see that negativity
increases that is, these users tend to
be even more negative
and what happens when tribe users
different then from different groups e
opposites meet then first
result is that they actually meet
very little so this interaction does not
happens and how rare though when it is
meet the discussion degenerates
absolutely there is not any kind of
dialogue and then you see that the
average sentiment as the number increases
of comments of the post then to grow
from discussion it is degenerating
then we wondered when
I try to change my mind instead
to people what happens i
attempts to banking that business
liz bufala re false information
it works or not, this is effective
we studied it on 54 million
so we have American users
collected in addition to the pages it disseminates
pseudo scientific information
scientific a third category that
of the banking and here the first result
is that usually very few users
in the amber pseudo scientific coaches
it interacts with the banking content
that is, the greatest user of the content
of banking is the user of the co
scientific chamber ie that to which
Actually the banking not serve you
however few users a few hundred
of thousands out of nine million users
few users interact with these
information and then what happens with
these users can convince them
in fact we have precisely measured the
so-called back fire effect that is
the effect of reinforcement in these practices
users after interacting with i
content of banking instead of
change your mind strengthen their on
own involvement and his own
adhesion and identity with cooking
then departure that pseudo
scientific then the banking reality
it does not seem to work and in these studies
they also had an impact on the
average
the journalist caitlin bb took care of the
column of washington post stroke fake
a column dedicated precisely to des bains
care for the fake news of the week e
after the preliminary publication of the
results of these studies decided to
close it just because it began to
feel that actually did not seem
then there will be an actual response and I
I would like to close by mentioning that cassan stand
he was in charge under the administration
obama of the regulated information office
affairs and sa stand quoted to ours
You work your article on blue blogger
assuming that probably the
best solution could be
to promote the culture of
humility and openness and therefore the idea that
I would like to go there tonight and that
we should probably all try to
get out of our consciences
so both scientists try to
get off a bit from the pedestal and
communicate better with people and in
general in our little daily is
so what we need and
also to be aware of the limits
cognitive of which we are all to which
we are all subjects and then starting
from this greater awareness we
as scholars we can instead use
the data associate patterns and try to
understand something more than all this
educational space particularly
complex thank you
[Applause]
