When two folks with opposing political views are proven the identical piece of data, they usually have radically totally different responses. Drawing on new analysis, Jens Koed Madsen, David Younger and Lee de Wit present that disagreements over the independence of data sources can play a major function in such a polarisation.
Analysis exhibits that folks with opposing political views might be uncovered to the identical proof from the identical supply and replace their beliefs in opposing instructions. At first look, this sort of “perception polarisation” may appear illogical. Certainly, it has usually been ascribed to irrational reasoning. However there are causes to assume that it could be extra rational than it first seems.
As psychologists, we’re fascinated by how perception polarisation would possibly come about – each as a result of we need to perceive what causes it and in order that we are able to advise governments and NGOs on how we would cut back it and foster extra constructive democratic debates. For that reason, we’re fascinated by whether or not this polarisation can happen from purely rational perception revision processes.
That’s actually to not say that each one political behaviour is rational, however it will be significant for public coverage to attempt to establish parts of polarisation which may moderately come up from logical cognitive processes in complicated media environments. Certainly, now we have lately argued that behavioural public coverage ought to begin from an assumption that individuals are affordable and rule this out earlier than we are able to declare important variations or irrational biases. That is often known as the Precept of Charity.
Dependencies and polarisation
In a latest research, we study whether or not folks’s beliefs concerning the sources of data can result in concern polarisation. Particularly, we assess their notion of supply dependencies. Loads of work has targeted on whether or not folks belief specific sources greater than others, however what we’re fascinated by is the perceptions folks have of the relationships between sources of data.
Sources might be perceived to be impartial of one another. If two sources that agree are fully impartial of one another, they’ve reached the identical conclusion with out speaking to one another, trying on the identical proof, or seeing one another’s reviews. Dependent sources in distinction might share proof or a solution to interpret knowledge, they could have mentioned a case earlier than making a press release, or they could each want the outcomes end up some particular method.
Throughout many domains of psychology, we see that individuals are delicate as to whether sources are perceived to be impartial. Sources perceived to be extra dependent ought to carry much less weight than reviews from sources which are impartial. This has two implications for polarisation that we take a look at in our research.
First, we study whether or not manipulating folks’s notion of dependence can generate polarisation. Second, we research whether or not folks on reverse sides of the political spectrum truly consider that the opposite “aspect” is extra dependent than their very own aspect, which might enable them to elucidate why others take a look at the identical proof and attain reverse conclusions.
Dependency issues
To check the primary concept, we ran an experimental research displaying that folks do polarise on points after they differ of their dependency beliefs. Contributors thought of whether or not a politician was responsible of embezzlement beneath situations by which totally different witnesses acknowledged that he was responsible or harmless.
We discovered members had been extra more likely to consider the politician was responsible after they had been advised that witnesses who claimed the politician was responsible had related backgrounds, learn the identical newspapers and adhered to the identical ideological place – and vice versa. The experiment confirmed us that merely manipulating folks’s perceptions of dependency was adequate to create polarisation.
To check the second perception, we examined whether or not folks with totally different political convictions ascribed increased dependencies to their political out-group than their in-group. In a UK survey, we requested folks to charge how dependent they thought individuals who voted Labour and Conservative had been (in addition to their very own political desire in order that we might group members).
We developed a 9-item survey that requested about facets like info consumption, ideological place, targets, life experiences, opinion transmission and extra. For instance, on info dependency, members rated Labour and Conservative voters from 1 (“all of them get their details about politics from the identical supply”) to 7 (“all of them get their details about politics from totally different sources”).
We discovered a powerful impact of dependency throughout all 9 gadgets, the place members on either side of the political divide thought their in-group was extra impartial and the out-group was extra dependent (Determine 1). This additionally held once we replicated the survey in the USA for Democrats and Republicans (Determine 2).

Determine 2: Dependency scores for Democrat and Republican supporters
Notice: For extra info, see the authors’ accompanying paper in Cognition.
The findings assist the concept that folks from each political sides consider that the “different” aspect consumes info from a structurally extra dependent ecosystem. This makes it simpler for folks to elucidate why different residents disagree with them on points.
If the “different” aspect actually did get their info from a extra dependent system, it might be topic to extra error and subsequently their positions ought to be taken much less severely. The issue is that either side appear to strongly consider this about one another, which is much less useful.
Tackling polarisation
Our findings have sensible implications. First, they recommend we ought to be extra cautious in merely assuming that that folks from “the opposite aspect” are simply irrational and that we have to perceive their notion of the knowledge ecosystem. Our findings recommend that there’s house for dialogue and dialogue, which is a constructive democratic view.
Second, the findings level to the varieties of conversations that may be wanted to de-polarise folks. If folks actually disagree on the reliability and dependencies of sources, they shouldn’t be persuaded by extra proof from these sources. As an alternative, the conversations ought to be about why we belief the sources we do and the way we see their relationships.
This has sensible implications for broader beliefs like local weather change denial. If deniers earnestly consider that local weather scientists are unreliable and that they’re all working collectively to push a selected agenda, extra reviews from scientists shouldn’t transfer their beliefs. As an alternative, scientists want to indicate how the scientific course of encourages impartial research.
Lastly, the mannequin we suggest within the paper suggests a polarisation cycle, which must be understood. That’s, if an individual’s prior beliefs align with the reason given by one aspect of the political spectrum, they will clarify that others disagree by inferring a better diploma of dependency.
Nevertheless, if the individual now believes the opposite aspect is extra dependent, they need to replace much less after they see reviews from that aspect, thereby privileging reviews from their “personal” aspect on new points. This might result in a back-and-forth the place residents with totally different beginning factors might polarise on totally different points as a result of they replace their beliefs concerning the ecosystem somewhat than simply on the speculation in query.
After all, the causes of polarisation are extra complicated and should contain totally different systemic and particular person components like social media algorithms, media consumption, biases, social networks, financial circumstances and extra. However we expect you will need to keep away from neglecting the cognitive beliefs of particular person residents and the way their perceptions of the knowledge atmosphere would possibly form the route by which they replace their beliefs on political points.
Our work enhances latest findings that individuals are much less more likely to hearken to consultants if they don’t assume they’re impartial, and means that an essential function of wholesome democratic media ecosystems is that there are impartial sources of data on the market which aren’t simply sticking to “the social gathering line”.
