In a previous post I considered why the opinion polls failed to accurately predict the result of the 2015 UK General Election. The polls appear to have been consistently wrong throughout the campaign and were widely publicised during the run up to the election. This raises the questions of whether they could also have unwittingly influenced the final result. The media often argue that they only reflect society, but in this case they may have been communicating a warped and inaccurate view of society.
The role of mass media?
There is widespread agreement that the mass media in general can influence peoples’ knowledge, attitudes and behaviour. What is debatable is the degree to which this occurs and whether opinion polls in particular can drive changes in voting patterns.
The evidence from research into the impact of opinion polls is somewhat mixed, probably because of the nature of the subject and a reliance on self-reporting. However, a study into the 1998 Canadian election concluded that there was evidence that polls affected voters’ perceptions of the chances of different parties winning and that they also influenced the vote. The latter was primarily the result of tactical voting where people switched their support away from a party that appeared to have little chance of winning and towards a party with a better outlook.
Facebook comments double after exit poll result:
The mass media also feeds into our social networks and there is indisputable evidence to show that social networks influence our behaviour as we are and have always been social creatures. Our herd behaviour is at the heart of the dispersion of ideas and behavioural change.
Herd theory suggests we are more heavily influenced by the actions of others in our network, and we like to be associated with the same values and norms as our social networks. However, word of mouth can also be very influential as we can be driven by what we think other people in our social networks are doing.
After the shock exit poll results were announced comments about the election on Facebook doubled confirming that polls are certainly a talking point. Opinion polls may form another piece of the jigsaw to help us determine what our wider network are intending to do.
Does the accuracy of information matter?
People often prefer to follow their gut instinct rather than listen to data, so maybe it does not matter? But people also hate uncertainty and suppress ambiguity because it slows our thought processes. The concern is that we are heavily influenced by the What You See Is All There Is (WYSIATI) rule and during the campaign the polls consistently told the same story.
There was also a great deal of uncertainty as the Conservative’s played on fear that Labour would have to form a coalition with the SNP to form a Government. If people had known the Conservatives were heading for a slim majority then this would have been a non-story in the first place.
In his book The Wisdom of the Crowd, James Surowiecki examined among other things how stock market bubbles arise. He noted that:
“The problem of putting too much information on a single piece of information is compounded when everyone in the market is getting that information.” James
Surowiecki, The Wisdom of the Crowd
He outlined experiments with students conducted by Jack Treynor where they were asked to estimate a quantity of items. In one experiment all participants were given additional information that pointed in one direction. Although the information was true, adding the additional guidance reduced their collective wisdom and meant their average guess was off by 15% compared with just 3% achieved in experiments where no extra information was given to participants.
The experiment by Jack Treynor could partly explain why the ‘wisdom poll’ conducted by ICM put the Conservative’s ahead of Labour, but still underestimated the magnitude of their lead. Overall, it seems clear that widely publicised and inaccurate information about the predicted result is likely to have skewed our own personal forecasts of the outcome. This in turn may have inevitably changed the behaviour of some voters, whether it be the decision to vote or not, and/or the party they ultimately voted for.
