When two folks with opposing political opinions are proven the identical piece of knowledge, 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 knowledge sources can play a big position in one of these polarisation.
Analysis reveals that individuals with opposing political opinions will be uncovered to the identical proof from the identical supply and replace their beliefs in opposing instructions. At first look, this type of “perception polarisation” might sound 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 keen on how perception polarisation may come about – each as a result of we need to perceive what causes it and in order that we will advise governments and NGOs on how we’d scale back it and foster extra constructive democratic debates. For that reason, we’re keen on 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 can be crucial for public coverage to attempt to determine components of polarisation that may moderately come up from logical cognitive processes in advanced media environments. Certainly, we have now just lately argued that behavioural public coverage ought to begin from an assumption that individuals are cheap and rule this out earlier than we will declare important variations or irrational biases. That is also referred to as the Precept of Charity.
Dependencies and polarisation
In a latest research, we study whether or not folks’s beliefs in regards to the sources of knowledge can result in situation polarisation. Particularly, we assess their notion of supply dependencies. Loads of work has centered on whether or not folks belief specific sources greater than others, however what we’re keen on is the perceptions folks have of the relationships between sources of knowledge.
Sources will be perceived to be unbiased of one another. If two sources that agree are fully unbiased of one another, they’ve reached the identical conclusion with out speaking to one another, trying on the similar proof, or seeing one another’s stories. Dependent sources in distinction might share proof or a technique to interpret information, they could have mentioned a case earlier than making an announcement, or they could each want the outcomes end up some particular means.
Throughout many domains of psychology, we see that individuals are delicate as to whether sources are perceived to be unbiased. Sources perceived to be extra dependent ought to carry much less weight than stories from sources which are unbiased. This has two implications for polarisation that we check 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 have a look at the identical proof and attain reverse conclusions.
Dependency issues
To check the primary thought, we ran an experimental research exhibiting that individuals do polarise on points after they differ of their dependency beliefs. Contributors thought of whether or not a politician was responsible of embezzlement beneath eventualities through which totally different witnesses acknowledged that he was responsible or harmless.
We discovered members had been extra prone 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 enough to create polarisation.
To check the second perception, we examined whether or not folks with totally different political convictions ascribed larger dependencies to their political out-group than their in-group. In a UK survey, we requested folks to price how dependent they thought individuals who voted Labour and Conservative had been (in addition to their very own political desire in order that we may 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 robust impact of dependency throughout all 9 objects, the place members on each side of the political divide thought their in-group was extra unbiased and the out-group was extra dependent (Determine 1). This additionally held once we replicated the survey in america for Democrats and Republicans (Determine 2).

Determine 2: Dependency rankings for Democrat and Republican supporters

The findings help the concept 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 could be topic to extra error and subsequently their positions must be taken much less critically. The issue is that each 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 must be extra cautious in merely assuming that that individuals from “the opposite aspect” are simply irrational and that we have to perceive their notion of the data ecosystem. Our findings recommend that there’s area for dialogue and dialogue, which is a constructive democratic view.
Second, the findings level to the kinds 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 a substitute, the conversations must 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 specific agenda, extra stories from scientists shouldn’t transfer their beliefs. As a substitute, scientists want to indicate how the scientific course of encourages unbiased 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 the next diploma of dependency.
Nonetheless, if the individual now believes the opposite aspect is extra dependent, they need to replace much less after they see stories from that aspect, thereby privileging stories 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 in regards to the ecosystem moderately than simply on the speculation in query.
In fact, the causes of polarisation are extra advanced and should contain totally different systemic and particular person elements like social media algorithms, media consumption, biases, social networks, financial circumstances and extra. However we expect it is very important keep away from neglecting the cognitive beliefs of particular person residents and the way their perceptions of the data setting may form the path through which they replace their beliefs on political points.
Our work enhances latest findings that individuals are much less prone to hearken to specialists if they don’t assume they’re unbiased, and means that an essential characteristic of wholesome democratic media ecosystems is that there are unbiased sources of knowledge on the market which aren’t simply sticking to “the celebration line”.
