British Ponder Role of Polls in Election Campaign

Article excerpt

BRITAIN'S public opinion pollsters are reexamining their role after getting the result of the April 9 general election completely wrong.

Amid calls to ban opinion polls before the next general election, the five main polling organizations have set up a special investigation unit. Its task will be to examine why, instead of predicting the Conservative Party's eventual victory, they all anticipated an election too close to call.

Robert Worcester, chairman of the Mori organization, which carried out surveys for the London Times, said large numbers of voters had made last-minute switches from the opposition Labour and Liberal Democrat parties to the ruling Conservatives.

Mr. Worcester denied claims by politicians and analysts that many voters had lied about their intentions.

The scale of the pollsters' error has jolted the leaders of a 300 million pound industry to such an extent that their collective organization, the Market Research Society, has ordered its director, Susan Stoessl, to carry out an urgent inquiry.

Some industry leaders worry that companies using market research to assess public reaction to their products will lose faith in the polls' reliability.

Of the other polls, NOP suggested a 3 point Labour lead, followed by Harris Research Center (2 points), Mori's 1 point, and ICM's dead-heat.

"Never before has every single poll strayed so far from reality," said Peter Kellner, an election analyst. He called for an "urgent post mortem" on the reason for the polls' fallacy.

Worcester, whose organization swung into action with a series of "reinterviews" immediately after the election result was known, turned up one of the first clues to what underlay the pollsters' collective error. Mori found that 11 percent of Liberal Democrats who, a week before polling day, said they would support their party, failed to do so on April 9. …
