While at our Weatherhead Center workshop,
we presented the results of our expert perceptions pilot
study. Dawn Brancati kindly served
as discussant, and she made a number of very useful and thought-provoking
comments. In this post, we are going to focus on one of them.
To provide a bit of background, the core of our survey is a
group of forty-nine questions encompassing all stages of the electoral
process—as defined by the UN here
and explained well by Jørgen Elkit and Andy Reynolds in a 2005 Democratization article.
The comment we are focusing on today is Dawn’s suggestion
that we distinguish between objective (factual) measures and subjective
(judgmental) measures within our survey. Understanding the difference between
objective and subjective measures is potentially important to our project for several
reasons, but for today one stands out.
Specifically, we believe that distinguishing objective from
subjective measures could provide us a good way of controlling for differences
between experts. This ability might be particularly important for electoral
contests where no consensus exists about whether they meet standards of electoral
integrity.
Consider the following table and figure. Table 1 shows the
distribution of responses in the Czech Republic to the question “Did the election trigger violent protests?” Our
Czech experts’ responses are very clear. There were no violent post-election protests
and, as such, all the experts say that voters were not threatened with
violence. This judgment reflects an objective fact: either there were violence
protests or there were not.

Now let’s look at Figure 1, which summarizes the responses
to the question: “Do rich people buy
elections?” in the Czech Republic. This question is one of four in our
survey that is worded exactly as it is in the latest round of the World Values Survey. This overlap
will be very useful for comparing elite and mass perceptions—a topic we will be
discussing in future posts.
Figure 1. Responses:
Do rich people buy elections in the Czech Republic?
As you can see, unlike for the election violence question there
is a divergence of responses. This result is unsurprising since this question is
more open for interpretation and subjective judgment than a question about whether
there was violence. What is “rich”? What does it take to buy an election? Do the
rich need to intervene the results directly or just buy the candidates? Clearly,
this question is more subjective and open for interpretation.
We find the differences between potentially objective and
subjective questions interesting because the former could be used as a proxy for
‘expert knowledge’ to better understand answers to the latter—we could check
whether objective events did or did not occur and then see if individual
experts’ answers reflect this fact.
We could then weight experts’ answers to subjective
questions according to their answers to objective questions. If an expert
‘fails’ (i.e. by being wrong) many of the objective questions, then it may be
worth discounting his/her answers. This could also partially address a point
raised by Andreas
Schedler in his 2012 piece in Perspectives
on Politics (available here). Schedler stresses the importance of holding
experts accountable for their judgments. Evaluating our experts’ knowledge
through an external verification method like the one we propose here could
provide a clear means of improving our confidence in the aggregate survey results.
Thanks again to Dawn Brancati for her insights.
