Overview
 Implicit Reaction TimeTM (IRT) measures the speed at which people express an opinion. In
the context of the upcoming General Election this helps us to understand the extent to which
voters hold strong positive associations between: different leadership qualities and Theresa
May or Jeremy Corbyn; different areas of policy and the Labour Party or Conservative Party;
and different statements on voting behaviours.
 Ipsos MORI conducted an IRT study among 929 adults aged 18-75 online between 15-17th
May 2017. We found that, at this point in the campaign:
Voters see Corbyn as in touch with ordinary people, and May as a capable leader who is good
in a crisis. Averaging across all attributes tested, May is seen as the best leader overall.
Both explicitly and emphatically, Conservatives fare better policies such as defence and security,
Brexit, the economy, immigration and taxation, whilst voters prefer Labour’s policies for housing,
welfare and benefits, and the NHS.
For voters, Brexit is still difficult to understand, with voters finding it most difficult to choose
between parties’ policies.
Emphatic responses regarding intention to vote are closer to reality than explicit ones, and with
only 37% of voters emphatically saying they have ‘definitely decided who to vote for’ suggesting
the outcomes of the election is still far from certain.

INTRODUCTION

4GE2017 IRT Study | June 2017 | v1 | Public
What is Implicit Reaction Time (IRT)?
• Based on the scientific principle of perceptual
fluency, IRT reveals the strength of
respondents' unconscious associations,
by using response time to measure
the distance between two concepts within a
neural network.
• The closer the association between two
concepts (for example, ‘Jeremy Corbyn’ and
‘capable leader’), the more conviction we
have and the more quickly and easily we are
able to respond.
• When things are not closely associated,
response times are slow, because it takes
more time for us to reconcile or work out the
relationship between the two concepts.
We process information in two
ways:
• System 1 “is the brain’s fast,
automatic, intuitive approach,
• System 2 “the mind’s slower,
analytical mode, where
reason dominates.”

Why is this important for GE2017?
 The outcome of recent elections has become harder to predict. The debates around Scottish
Independence, and UK independence from the EU have increased the number of issues at
stake, and have also made it harder to predict voter turnout.
 Moreover, the dynamic of choosing who to vote for is never constant: whether voters are
most attracted to leaders, policies or parties changes each year. Currently, voters say that
leadership is more important in deciding who to vote for in 2017 than it was in 2015.
 It is therefore important to try and go beyond the stated answers given in surveys, and seek to
uncover the unconscious associations that may ultimately decide who someone votes for.
 Ipsos MORI therefore sought to use IRT to help us uncover unconscious associations in three
different areas:
1) The extent to which voters hold strong positive associations between different
leadership qualities and Theresa May or Jeremy Corbyn.
2) The extent to which voters hold strong positive associations between different areas of
policy and the Labour Party or Conservative Party.
3) The extent to which voters hold strong positive associations between different
statements on voting behaviours.

LEADERS: Key findings
 May is seen as a more favourable leader than Corbyn on most fronts, seen as the best leader
voters overall, by her supporters, and those who voted to Leave. She is also perceived just as
well as Corbyn by Remain voters. In contrast, Corbyn has lost ground among 2015 Labour
voters – particularly the case for extent of association with: ‘capable leader’, ‘clear vision for
Britain’, ‘good in crisis’, ‘good negotiator’, ‘sound judgement’.
 With the exception of being ‘in touch with ordinary people’, May is broadly in line with or
outperforms Corbyn in all other areas. Though voters are more uncertain whether she is
‘patriotic.’
 Among Labour supporters, Corbyn is strongly associated with being ’honest’ and ‘genuine’,
but they are less confident he ‘understands Britain’s problems’ or has a ‘clear vision’.
Conservative supporters are least convinced that May is ‘patriotic’ or is ‘in touch with
ordinary people’ (three in ten chose Corbyn in this attribute).
 Associations are closely aligned with age, which become more favourable towards May,
particularly with reference to being a ‘capable leader’.

PARTIES: Key findings
 The Conservative Party is seen as having the best policies in relation to defence and security,
Brexit, the economy, immigration and taxation.
 The Labour Party is seen as having the policies in the areas of housing, welfare and benefits
and the NHS – but only by a small margin. The only policy area in which the Labour party’s
policies outstripped the Conservatives’ was poverty and inequality.
 Looking at these findings by voting intention, current Conservative voters, are most
emphatic about their party’s policies on defence and security and the economy, whereas
Labour supporters are most emphatic about Labour’s policies on welfare and benefits.
 Although Brexit is seen as the biggest issue, voters are finding it the area where it is most
difficult to choose between parties’ policies: only one in three gave an emphatic response at
this question, illustrating the high levels of uncertainty surrounding the Brexit process.
 Younger voters are more likely to hold strong positive associations with Labour: on almost all
areas, those aged 18-34 were more likely than older voters to emphatically support Labour.

VOTING: Key findings
 Implicit Reaction Time testing highlights the overclaim made by the general public through regular
polling.
 Emphatic responses regarding voting intentions are closer to reality than explicit ones. Although four in
five (83%) claim that they are absolutely certain to vote in this election, two thirds say this emphatically, a
much more realistic figure.
 Furthermore, whilst two thirds claim that they have definitely decided who to vote for, only 37% say this
emphatically, indicating that both election outcomes are still far from certain.
 Those intending to vote Conservative are 7 percentage points more likely to say emphatically that they are
certain to vote, and 10 percentage points more likely to say emphatically that they have definitely decided
who to vote for.
 Those intending to vote Conservative are also 19 percentage points more likely to emphatically say that
they always vote in elections.
 Leave voters are more likely to have already decided who to vote for, whilst Remain voters are more likely
to consider voting tactically. However, more Remain voters say (both explicitly and emphatically) that
voting should be compulsory.
 Perhaps unsurprisingly, those aged 55+ are significantly more likely to say (both explicitly and
emphatically) that they are certain to vote in this election, and registered to do so.

Method (i)
Implicit Reaction Time™ by Ipsos & NEUROHM is the second generation of latency measures. It incorporates
a ‘noise’ reduction algorithm to control individual differences in the speed of the neurotransmission as well
as for the level of fatigue or length of words:
• Participants were exposed to stimulus and then underwent a calibration exercise to account for
individual variation such as computer speed, motor skills.
• For each exercise, participants were shown set of statements or phrases, and asked to select the answer
they most closely associated with the statement.
• Looking at both the response and the speed of response allows us to capture both their explicit and
implicit response.
• We analysed the speed with which they answer the scale to uncover their unconscious conviction.
Fieldwork took place between 15-17th May 2017 with 929 adults aged 18-75 online in the UK.
Data has been weighted by age, gender, region and work status.
Each participant completed IRT modules for all three exercises – the answer options and attributes for which
are shown overleaf. The order in which participants viewed attributes within a module was randomised, and
the answer options were rotated from Left to Right for different halves of the sample.
The three IRT modules were completed as part of a wider online survey collecting further information about
voting intention and the General Election.
