Transcript 7 Measuring the RAS model
Receive-Accept-Sample Model
an information-processing model
GV917
How do Citizens acquire information and
convert it into public opinion?
Two Definitions:
1.
Considerations: any reason that might induce an individual to decide a
political issue one way or the other. Considerations, thus, are a
compound of cognition and affect—that is, a belief concerning an object
and an evaluation of the belief.
2.
Political messages:
a.
b.
Persuasive messages: arguments or images providing a reason for
taking a position or point of view; if accepted by an individual, they
become considerations.
Cueing messages: consist of ‘contextual information’ about the
ideological or partisan implications of a persuasive message. They
enable citizens to perceive relationships between the persuasive
messages they receive and their political dispositions, which in turn
permits them to respond critically to the persuasive messages.
Axioms of RAS Model
A1. Reception Axiom. The greater a person’s level of cognitive
engagement with an issue, the more likely he or she is to be
exposed to and comprehend—in a word, to receive—political
messages concerning that issue.
A2. Resistance Axiom. People tend to resist arguments that are
inconsistent with their political predispositions, but they do so
only to the extent that they possess the contextual information
necessary to perceive a relationship between the message and
their predispositions.
A3. Accessibility Axiom. The more recently a consideration has
been called to mind or thought about, the less time it takes to
retrieve that consideration or related considerations from memory
and bring them to the top of the head for use.
A4. Response Axiom. Individuals answer survey questions by
averaging across the considerations that are immediately salient
or accessible to them.
“True attitudes” vs “Opinion statements”
The survey responses that people make within the
proposed model may reasonably be described as
attitudes or opinions, in that they represent people’s
true feelings at the moment of answering a given
survey question; they could not, however, be
described as “true attitudes,” in the technical sense of
the term, because survey responses are not assumed
to represent anything more than a single aspect of
people’s feelings toward a given attitude object.
Opinion statements, as conceived in this model, are
the outcome of a process in which people receive new
information, decide whether to accept it, and then
sample at the moment of answering questions.
Measuring ‘Considerations’ – The 2005
Pre and Post Election Surveys for BES
What do you think is the most important
problem facing the country at the present
time?

The Reception Axiom
Many issues or considerations are salient to the
public at any one time
The Reception Axiom means that people will pay
attention to new information about the issue they
think is most important to them during an election
campaign
This new information may or may not change their
minds, but the issue should still remain salient to
them
So a salient issue at the start of an election
campaign should still be salient at the end – But is
it?

The Implications for the Reception Axiom
55 per cent of people who chose one of the top six salient issues in
the pre-election survey chose the same issue in the post-election
survey
This does not measure all the ‘considerations’ in people’s minds –
only the most important one.
But it shows how the saliency of considerations can vary quite a lot
over time – particularly during an election campaign
The Reception Axiom suggests that an issue should remain salient
– but there is a lot of change in perceptions of saliency
We don’t know from this if the issue ceases to be salient for the 45
per cent who change their minds, but clearly receptivity can change
as the issue priorities change
But the top two salient issues in the pre election survey (immigration
and the NHS) showed a lot more stability than the bottom two
(Education and Europe) – saliency promotes stability.
The Resistance Axiom
People will resist arguments that are inconsistent with their
predispositions – but only if they think the message is relevant to
their considerations
As we have seen in the 2005 election immigration and asylum
seeking were the most important issues both before and after the
election
If we focus on respondents who thought immigration and asylum
seeking was the most important issue in the pre-election survey,
then the Labour partisans among them should be less critical of
the government on this issue compared with others
Why? Because they are more predisposed to support ‘their’
government – they will resist criticism of it.

Implications for the Resistance Axiom
The people who attach great importance to
immigration/asylum-seeking do so because
they are worried about it, which makes them
critical of the government
However, a predisposition to support the
government as measured by Labour
partisanship mitigates the criticisms quite a
bit.
The Accessibility Axiom
Recent ‘top of the head’ information should be very
important, particularly for people who are not very
interested in politics and so have few considerations
in their minds
During the 2005 election the Conservatives made a
lot of the immigration issue – so Conservative
partisans who weren’t that interested in the election
campaign should have been quick to cite
immigration as a key issue because it was at the
‘top of their heads’
How interested and uninterested Conservatives Reacted
to Immigration in the 2005 Election Campaign
Note: The Figures measure the percentages who were stable in their selection of immigration as the most important
issue before and after the election

Implications for the Accessibility Axiom
For those interested in politics both Conservatives and nonConservatives were equally stable in their choice of immigration
as the most important issue in the pre and post surveys (58%
and 57%)
However, for those not interested in politics Conservatives were
significantly more stable in their choice of immigration (76%) than
non-Conservatives (70%) though both were more likely to cite
the issue than the interested
Why? Because the uninterested Conservatives used the most
recent ‘top of the head’ considerations when answering the
question by following their party’s lead
Interested Conservatives were less likely to do this because they
had more considerations in their minds when responding to the
question.
The Response Axiom
Individuals average across the considerations they
have in mind when responding to questions
If people have lots of considerations in their minds
because they are interested in politics and in the
election, then their responses should be relatively
stable – they are averaging across a lot of
information – and it is harder to change many bits of
information all at once
If people have few considerations in their minds
because they are not interested in politics then their
responses should be relatively unstable – they are
averaging across very few bits of information and so
their positions can easily change.

Implications for the Response Axiom
Opinions are more stable among those interested in
politics for Law & Order, Education, NHS and the
Economy than opinions for those not interested in
politics
But opinions are less stable among those interested
in politics for Immigration and Europe
As the discussion of the Accessibility Axiom showed
the latter could be explained by the campaign – the
Conservatives concentrated on immigration in
particular but were also Euro-sceptic and so the
issue remained salient for those not interested in
politics

Conclusions
The different axioms in the RAS model lead to
different predictions about how people will
process and use information depending on their
predispositions and the context in which it
appears
An election campaign makes politics salient for
most people since they pay attention to it
But some are not interested in the election and
they react differently to new information in
comparison with those who are interested.
Levels of Interest in the AV Referendum of 2011
varied a lot and these had big effects on who
was likely to vote
