This paper assesses the impact of political knowledge on electoral choices during the 2001
British Election. We explore the impact of knowledge of party platforms on taxation,
privatisation and Europe on the relationships between respondents’ positions on these
issues and voting behaviour. Our results show that knowledge does, in fact, affect how
people vote. This was especially evident for all issues in the contrast in vote for the
Conservatives and Liberal Democrats. On the other hand, knowledge about the party
platforms on taxation and privatisation had little effect on the contrast on the vote choice
between Labour and Liberal Democrats. However, knowledge of party platforms about
Europe, an issue about which voters would have difficulty finding effective short cuts, did
have a significant impact on all vote choices. Perhaps the most important implication of
these findings is that the Liberal Democrats do seem to benefit when voters are
knowledgeable, suggesting that their performance at the polls could be improved with
greater exposure.

Introduction There is growing interest in the concept of political knowledge. Much research in the area
is normative, focusing on what can be labeled ‘civics’ knowledge—i.e., knowledge about
government and political institutions—and how it might be expected to affect the
functioning of democracy (see Schumpeter, 1967). There is substantial evidence that this
type of political knowledge is generally low, especially in the United States (see Fishkin,
1999). Moreover, research is quite convincing that the electorate is stratified according to
political knowledge, with the knowledgeable tending to differ from the less knowledgeable
in the structure, consistency and stability of their political attitudes and ideologies (for
example, Delli Carpini and Keeter, 1996; Bartle, 1997; Sinnott, 2000). Research also
shows that voters are generally uninformed about political issues (see Page and Shapiro,
1992). It is less obvious, however, whether or not knowledge of party platforms affects the
electoral choices of voters.
Some writers suggest that voters with low levels of political knowledge are able to get by
as if they are well informed. Popkin (1994), for example, suggests that voters may use
‘heuristics’ or information short-cuts, such as following the position taken by a group or
leader that the citizen believes has their interests at heart (see also Sniderman et al, 1992;
Neuman et al, 1992; Zaller, 1992; Graber, 2001). Meanwhile, others argue that while it
may be the case that individual voters make uninformed choices, the public as a whole still
makes the choice it would make if everyone were fully informed. While some voters may
make the ‘wrong’ choice in one direction, other voters will do so in the opposite direction.
This results in the errors being cancelled out, meaning that the collective decision of
society as a whole is the ‘right’ one (Shapiro and Page, 1988).
Such attempts to rescue the voter from an apparent ignorance have been fervently disputed.
For example, both Zaller (1992) and Delli and Keeter (1996) argue that voters cannot
deploy the kinds of short-cuts suggested by Popkin (1994) unless they have sufficient
knowledge about the provenance of the messages that they hear. Moreover, Bartels (1996)

argues that voters with low levels of political knowledge do make different choices from
those with higher levels of knowledge with important implications for the overall outcome
of elections (see also Lupia, 1994; Lupia and McCubbins, 1998). Bartels findings can be
little more than suggestive, however, because they rely on American National Election
Study data, which contain only interviewers’ assessments of respondents’ levels of
political knowledge rather a direct measure. Nonetheless, research using ‘deliberative
polls’ has shown that giving people information can indeed change their views (Fiskin,
1997; 1999).
These arguments all assume that knowledgeable voters follow, at least in part, an issue-
based procedure for deciding how to vote (see Brody and Page, 1972; Kessel, 1972). This
too is, of course, strongly contested. While public discourse centres on the issues
advocated by the parties (and this is what to a considerable extent gives the parties
normative legitimacy to implement their manifestos when in office), voting decisions are
also based on other considerations. For example, criteria such as the personality of the
party leaders (Stewart and Clarke, 1992) and the economic record of the incumbent
government have also been shown to be important (Key, 1968; Fiorina, 1981; Lewis-Beck,
1988). Moreover, it is by no means clear that political knowledge is all that relevant to
these other criteria. Most obviously, political knowledge is not a prerequisite for
understanding how much disposable income one has. In fact, Fiorina’s (1981)
retrospective theory of economic voting holds that economic voting does not require a
sophisticated understanding of the policy issues.
Aside from a few exceptions, research on political knowledge has focused mostly on the
United States. Nonetheless, with its multi-party system and multidimensional cleavage
structure, Britain provides a potentially valuable arena in which to test the impact of
political knowledge. A multi-party system makes the task of selecting the party whose
policies best accords with one’s own issue preferences less straightforward than in an
essentially two party system as in the United States. In other words, if political knowledge
is important it should be clearly detectable in Britain. Changes to party manifestos

regarding the major issues make the 2001 British election an even more interesting testing
ground for the effects of political knowledge on issue voting.
The goal of this paper, then, is to contribute to the debate over the effects of political
knowledge on electoral choices. Our concern is with whether knowledge of party
platforms leads to a closer accord between voters’ preferences and party positions. We
assess these relationships during the 2001 British Election. Although our primary concern
is with testing the impact of knowledge on issue-based voting, we control for other factors
held to be related to voting.
Issues and Party Platforms in 2001 We begin with a discussion of the platforms on the issues of taxation, privatisation and
European integration for the three major parties—Labour, Conservatives and Liberal
Democrats. In particular, it is necessary to explain how the party platforms changed in the
years leading up to the 2001 election.
A simple stereotype of party competition in Britain before 1992 suggests that it was
organized along the left-right continuum, with the Labour party situated on the left, the
Liberal Democrats in the centre, and the Conservatives on the right. Analysis of party
manifestos suggests that this was indeed an appropriate way to characterise much political
debate in Britain during this period, particularly on issues such as nationalisation and
privatisation of industry, and taxation and spending, which are central to the left-right
continuum (see Budge, 1999). Since party positions exhibited a fair degree of continuity
over time on these issues, the use of shortcuts based on overall left-right positions could be
considered appropriate. In fact, we might expect that the less knowledgeable were as
effective as the more knowledgeable in translating their issue preferences into appropriate
party choices because the ideological positions of the parties were well entrenched for
many years.

Important though this simple picture was before 2001, it no longer holds true. In less than a
decade, the ideological space occupied by British political parties has changed drastically.
There is significant empirical evidence, both from party manifestos (see Bara and Budge,
2001) and from the empirical studies of the self-reported ideological positions of Members
of Parliament representing the three major parties (see Norris and Lovenduski, 2001), that
the ideological positions of the parties have changed drastically. In other words, the simple
story of the Liberal Democrats sitting between the Labour Party and the Conservative Party
is no longer true on most left-right issues.
Of course, the most significant change was the coming of ‘New Labour’. The widely
publicised move of the Labour party towards the centre of the political spectrum after the
1992 election began a closing of the gap between Labour and the Liberal Democrats. By
2001 the Liberal Democrats were firmly to the left of the Labour party on many important
issues (Bara and Budge, 2001). For example, the Liberal Democrats were the only party
promising to raise income taxes to spend more on public services such as health and
education. There is also sufficient evidence to suggest that the Liberal Democrats had also
moved to the left of the Labour Party on the privatisation issue during the 2001 election.
The Labour Party’s proposal to privatise the London tube and the Liberal Democrats vocal
opposition to this proposal are evidence of this point.
Changes in party manifestos and the fact that it cross-cuts with traditional left-right issues
meant that the issue of Europe was also a particularly difficult one in 2001 for those voters
wishing shortcuts. As recently as 1983, Labour was the most Eurosceptic party, but it has
since adopted a somewhat more Europhile position under Neil Kinnock and Tony Blair. In
contrast, from being a Europhile party in 1983 (when Margaret Thatcher said that it would
be folly to think of leaving Europe), the Conservatives are now much more Eurosceptic.
These factors make it difficult for voters to simply extrapolate from their knowledge of
general positions on the left-right dimension. The Liberal Democrats, on the other hand,
have maintained a fairly positive, although not very well publicised, approach to Europe
Political Knowledge and Electoral Choices by
Robert Andersen,Anthony Heath and Richard Sinnott

throughout, and since 1997 their manifesto has been considerably more positive about
Europe than that of either of the other two parties (Bara and Budge, 2001).
Given these changes to the ideological positions of the major British political parties
leading up to the 2001 election, one might expect that less knowledgeable voters would be
considerably more likely to mistakes in translating their own issue preferences into votes.
In other words, relying upon past impressions in order to ascertain which party is closest
to them on particular issues would be largely ineffective. If political knowledge does affect
people's ability to process new political information, we might expect those with higher
knowledge are better able to distinguish the new positions of the parties on Europe than
those with lower levels of knowledge. Certainly, previous work on the evolution of the
race issue in the United States suggests that this might be the case (Carmines and Stimson,
1980; 1989).
From these observations we can derive three general hypotheses about the relationship
between knowledge and issue voting, all of which we test in the present paper. First, we
expect that knowledge will have impact on the relationships between personal positions on
issues and vote. In other words, those with higher knowledge will be better able to match
their policy preferences to party platforms on taxation, privatisation and Europe. Secondly,
we expect that this impact will be strongest for the contrast in vote between the
Conservative Party and the Liberal Democrats since they are the two parties on the
opposite ends of the political spectrum. Finally, these two hypotheses imply a third
hypothesis, that states that mistakes do not cancel each other out. That is, we expect to find
significantly different average voting patterns between the knowledgeable and less
knowledgeable.
Data and Methods
We employ data from the 1997-2001 British Election Panel Study (BEPS). The baseline
sample for the BEPS was the 1997 British Election Study, which conducted 3,615
Political Knowledge and Electoral Choices by
Robert Andersen,Anthony Heath and Richard Sinnott
6
interviews with respondents representative of British voting age population. The initial
response rate of the British Election Study was 62 percent (see Thomson et al. 1999 for
more details). BEPS consists of eight waves, each involving re-interviews with the
original respondents. Although we use information from the initial wave, we rely primarily
on waves seven and eight, which were conducted shortly before and following the 2001
election, giving a sample size of 2,206.
To test our hypotheses we fit a multinomial logit model with vote as the dependent
variable. Our concern is with the contrasts in vote between the three major parties—
Labour, Conservative and Liberal Democrat. We concentrate only on these parties both
because they receive most of the votes, and because it is between them that the major left-
right issues are fought. Our primary explanatory variables are knowledge of party
platforms on taxation, privatisation, and the European Union and respondents’ attitudes
toward those issues. Most importantly, the model includes interaction terms between the
knowledge variables and respondents’ positions on the issues in order to test whether
knowledge strengthens the relationship between attitudes and vote. The effects of these
interactions are shown using effect displays (see Fox, 1987). Finally, the model controls
for region, gender, education, age, opinions of party leaders, and economic perceptions.1
More details of the explanatory variables are given below.
Respondents’ Positions on Issues
We use 11-point (A-K) scales for ascertaining respondents’ attitudes toward taxation and
spending, nationalisation and privatisation, and the European Union. High scores represent
right-wing attitudes, while low scores represent left-wing attitudes. The survey questions
are as follows:

(1) Taxation and Spending “Some people feel that the government should put up taxes a lot and spend much more on health and social services. These people would put themselves in Box A. Other people feel that the government should cut taxes a lot and spend much less on health and social services. These people would put themselves in Box K. An other people would put themselves in Box K. In the first row of boxes, please tick whichever box comes closest to your own views about taxes and government spending.” (2) Nationalisation and Privatisation “Some people feel that the government should nationalise many more private companies. These people would put themselves in Box A. Other people feel that the government should sell off many more nationalised industries. These people would put themselves in Box K. An other people would put themselves in Box K. In the first row of boxes, please tick whichever box comes closest to your own views about nationalisation and privatisation.” (3) European Union “Some people feel that Britain should do all it can to unite fully with the European Union. These people would put themselves in Box A. Other people feel that Britain should do all it can to protect its independence from the European Union. These people would put themselves in Box K. An other people would put themselves in Box K. In the first row of boxes, please tick whichever box comes closest to your own views about European Union.”
Political Knowledge Rather than use a single measure of political knowledge, we constructed three separate
measures of knowledge based on the party platforms on taxes, privatisation and European
integration. To do so we rely on questions similar in structure to those of respondents’ own
opinions about the issues. In this case, however, respondents were asked to place each of
the political parties on the 11-point left-right scale. Those respondents who placed all the
parties in the correct positions relative to each other—i.e., those with high knowledge—
were assigned a score of 1. All others were coded 0. Empirical information about the
relative positions of the parties was gathered from the 2001 party manifestos (see also
Budge, 2001), and the 2001 Representation Study (Norris and Lovenduski, 2001).
Following our earlier discussion, knowledgeable respondents placed the Labour Party in
Political Knowledge and Electoral Choices by
Robert Andersen,Anthony Heath and Richard Sinnott

the middle between the Conservatives on the right and the Liberal Democrats on the left for
all three issues.
It is worthwhile to assess the validity of our measures of political knowledge. There has
been some debate about the relationship between civics knowledge and knowledge of
issues (see Luskin, 1987). Therefore, one way to assess our measures is to compare them
to a measure of civics knowledge. BEPS included a political knowledge quiz that is well
suited for this purpose. Table 1 displays the mean scores on the political knowledge quiz
for the low and high knowledge groups for each of the three issues under investigation. For
all three issues, those with knowledge of the platforms of the three major parties score
higher average scores on the civics political knowledge quiz. Table 1 suggests, then, that
our measures adequately differentiate those with high political knowledge from those with
low political knowledge.

Control variables

is treated as a set of four dummy regressors: (1) university degree, (2) some post-
secondary education, (3) A-level, and (4) O/CSE level. Those with less education or
foreign qualifications are the reference category. Age is coded as two dummy regressors—
65 years and older, and 35-64 years old—with those under 35 years of age as the reference
category. Opinions of leaders were measured using questions that asked respondents how
well they thought each of the leaders of the three major parties—Tony Blair (Labour
Party), William Hague (Conservative Party) and Charles Kennedy (Liberal Democrats)—
would do as Prime Minister. Finally, the model also controls for retrospective economic
perceptions. We include two variables from questions asking respondents how well they
thought the British economy performed during the past year, and how their own household
income had changed in the past year.
Results
Table 2 presents descriptive statistics for some of the key variables in the analysis. A
number of things are noteworthy. First, it is clear that opinions toward the party leaders
differed substantially, with Labour leader Blair being most popular and Conservative
leader Hague being the least popular. The distributions of the knowledge variables are also
interesting. Nearly 30 percent of respondents were knowledgeable of the relative party
positions on taxation, while less than 15 percent accurately placed the parties on
privatisation and Europe. The relatively large proportion of knowledgeable people on
taxation perhaps reflects that it was one of the most discussed issues during the campaign
(see Bara and Budge, 2001). These points will be revisited later in the paper.

Our analysis now turns to the relationships between platform knowledge, respondents’
views on issues and political party choices. As we discussed earlier, the Liberal
Democrats are to the left of the Conservatives and Labour on all three issues that we
examine. We should expect, then, that if issue voting does take place those with right-wing
policy preferences would be inclined to vote for either the Conservative Party or Labour
Party rather than the Liberal Democrats. In our multinomial logit model, we also expect
that the parameters for the Labour/Liberal Democrat contrast to be much smaller than those
for the Conservative/Liberal Democrat contrast since the Liberal Democrats are much
further away ideologically from the Conservative Party than they are from the Labour
Party. More importantly, however, we expect that these relationships will be strongest for
Political Knowledge and Electoral Choices by
Robert Andersen,Anthony Heath and Richard Sinnott
11
those who are knowledgeable about party platforms. In other words, we expect to find
significant interactions between the knowledge variables for each issue and personal
attitudes toward those issues.
Table 3 displays the coefficients from the multinomial logit model fit to the data. It is
evident that opinions of leaders play an important role in party choice. Opinions of all
three leaders are significantly related to each of the two party choice contrasts. Simply put,
if voters felt the party leader could make a good Prime Minister they were highly likely to
vote for his party. It is also obvious that perceptions of the economy played a significant,
though lesser, role in electoral choices. Voters who felt that the economy had done well,
and their own household income had improved, during the past year were much more likely
to vote for the incumbent Labour Party. As one might expect since both parties were in
opposition, the effects are smaller for the contrast between the Conservative Party and
Liberal Democrats.

We now turn to an assessment of the impact of issues on vote. What is striking here are the
strong negative effects of platform knowledge on both the Conservative/Liberal Democrat
and Labour/Liberal Democrat contrasts. These finding have important implications since it
implies that the Liberal Democrats suffer in the polls because the electorate is unaware of
their position on the issues. It is also interesting that although there are some significant
coefficients, the effects of respondents’ positions on issues has only small main effects on
vote when controlling for knowledge and the interaction between positions on issues and
knowledge about the party platforms. Nevertheless, there are some highly significant
interactions between respondents’ own viewpoints on the issues and their knowledge of the
parties’ viewpoints on these issues. We now turn to the effects displays for each of impact
of each of the issues on vote in order to highlight this latter point.
We shall first examine the relationship between attitudes toward taxation, knowledge about
the party stances on this issue, and vote. Figure 1 displays the fitted probabilities of the
vote contrasts for the Labour Party and Conservative Party with the Liberal Democrats, for
those with high and low political knowledge. Aside from attitudes toward taxation and
knowledge, all other variables are set to their means. Recall that high values on the attitude
scale represent right-wing attitudes—i.e., they favour tax cuts rather than government
spending. There is no obvious relationship between attitudes towards taxation and voting
between the Labour Party and the Liberal Democrats—the probabilities of voting Labour
for both the highly knowledgeable and less knowledgeable are fairly constant regardless of
where respondents stand on the issue. The situation is similar for vote choice between the
Conservative Party and Liberal Democrats for the less knowledgeable—again the
probability remains fairly stable regardless of one’s viewpoint on the issue. However, the
interaction between knowledge and attitudes towards taxation is large and statistically
significant for the Conservative/Liberal Democrat contrast. Here we see the expected
pattern among the knowledgeable of right-wing attitudes being associated with higher
propensities to vote for the Conservative Party. In fact, the relationship is very strong, with

the probability at about .1 for those on the far left, and .7 for those on the far right of the
issue.

We now turn to Figure 2 to assess the effects of knowledge on the relationship between
attitudes toward privatisation and vote. Here we see a similar pattern to that observed in
Figure 1. Once again knowledge has little impact on the Labour/Liberal Democrat contrast,
but a dramatic impact on the Conservative/Liberal Democrat contrast. Neither the highly
knowledgeable nor the less knowledgeable appear to choose the Labour Party over the
Liberal Democrats based on their stances on the privatisation issue. In some respects this
is not surprising since, although the Liberal Democrats were to the left of Labour on the
issue, the distance between the two parties was not dramatic. On the other hand, there is a
large difference in Conservative and Liberal Democrat policy on the issue, and this is
reflected in the attitude-vote relationship, but only for the highly knowledgeable. Among
the highly knowledgeable, those who are far on the left are highly unlikely to vote
Conservative over Liberal Democrat (p<<.1), while those on the far right of the issue are
highly likely to choose the Conservative Party (p=.7). In other words, those who are
unaware of the party positions on the issue are not matching their vote choices to their own
preferences as well as the knowledgeable are.

Figure 3 displays the effects of knowledge on the relationship between attitudes toward
European integration and vote. The pattern in this figure clearly differs from those for the
other issues for two reasons. First, the relationship between attitudes and vote tends to be
in the correct direction for both knowledgeable and less knowledgeable voters. In other
words, for all voters as attitudes toward Europe become more right-wing, voters tend to
become more likely to vote Labour and Conservative rather than Liberal democrat. (Recall
that in the case of taxation and privatisation such a pattern was seen only for the
knowledgeable voters for the Conservative/Liberal Democrat contrast). Moreover, unlike
with the taxation and privatisation issues, we find significant interactions between
knowledge and attitudes for both the Conservative/Liberal Democrat and Labour/Liberal
Democrat contrasts. In both cases, those with knowledge of party platforms are more likely
match their own political ideology to the party best representing that ideology.

Discussion
This paper set out to assess the effects of political knowledge on political choices. Our
primary goal was to show that issue voting does take place, but that it is conditioned on
knowledge of party platforms. In other words, voters do vote according to issues, but they
can do this properly only when they have knowledge of the party platforms on the issues.
Our results provide significant evidence that this is in fact true. We found significant
interactions between knowledge and positions on issues and their impact on vote for all
three issues that we examined. Those with higher knowledge, in all cases, were more
likely to match their own issue positions to parties with similar positions. These findings
indicate that, contrary to the argument of some political scientists, errors in vote choices
made by the less knowledgeable do not cancel each other out. This suggests, then, that
election outcomes could be considerably different if the electorate as a whole was
generally well informed about the party platforms.
Our analysis also showed that the effects of knowledge on issue voting were most
pronounced for the Conservative/Liberal Democrat contrast. For each of the three issues
knowledgeable respondents were far more likely to match their issue preferences to party
platforms than for the less knowledgeable. Of course, we expected this to be the case given
that the Conservative Party and Liberal Democrats occupy the opposite ends of the left-
right spectrum for all the issues.
The findings with respect to the Labour Party/Liberal Democrat vote contrast do not fit the
expected pattern, however. Only for Europe was there an interaction effect between
knowledge and position on issues on Labour/Liberal Democrat vote. This interaction was
in the expected direction—i.e., the knowledgeable were more likely to vote Labour the
more right-wing they were—but even here the knowledgeable were much more likely to
vote Labour even if they were on the extreme left of the issue. In fact, this pattern held up
for all the issues. That is, with all issues even the knowledgeable were more likely to vote
Labour regardless of whether they were left or right. This suggests, perhaps, that the public

realised that the differences in policy between Labour and the Liberal Democrats was
relatively small, and that the Labour Party was seen as a more viable party to achieve
election.
It is interesting that the main effects of all three knowledge variables had a positive impact
on vote for the Liberal Democrats. This suggests that a continuing problem for the Liberal
Democrats is their lack of visibility to the electorate. Even at the end of the election
campaign, it seems that many voters still do not know where the Liberal Democrats stand
on the issues.
Our results also suggest one reason the Conservative Party’s emphasis on issues such as
Europe failed to deliver the expected gains in votes in 2001. Despite the fact that a
majority of the electorate lie to the right with the Conservatives on the European Union
issue, less knowledgeable voters simply failed to connect their own preferences with
Conservative Party’s platform.
We are not suggesting that issues were of utmost importance to voters. In fact, it is
important to emphasise that issues were generally less important to voters than opinions
towards party leaders, even for those with high political knowledge. Nonetheless, these
results do suggest that knowledge of where parties stand on issues does induce a stronger
relationship between issue preferences and vote. It is also highly likely that changes in
party positions on the issues for the 2001 election made knowledge even more important
than in the past. Less knowledgeable voters, who might continue to use out-dated rules of
thumb, seemed much more likely to make incorrect voting choices. In conclusion, our
results suggest that knowledge of party platforms does affect electoral choices.
