Pollsters Scramble As Fewer People Take Their Phone Calls
Increased cost and time needed for traditional telephone surveys spurs the
rise of unproven digital alternatives; ‘a lot of experimentation is
going
on’
Opinion research firm Civis Analytics draws from several different survey
methods, working from open-plan offices in downtown Chicago.
Opinion research firm Civis Analytics draws from several different survey

Each day, millions of calls are placed to phone numbers that have been
disconnected or are no longer in service. Everyone misdials—men and
women,
rich and poor, blacks and whites.
Scott Richards wants to replace the familiar “Your call cannot be
completed
as dialed” message with a different one: “Would you like to
take a survey
?”
His is among a spate of ideas bubbling up for new ways to sample public
opinion. The alternatives are coming because the traditional method—
randomly calling phone numbers again and again until someone answers—
has
grown far more labor intensive and costly in recent years.
One idea is to push surveys on people who mistype the name of a website.
Polling companies are assembling large, standing panels to survey online.
For certain websites, Google is asking internet users to answer surveys
before they can get access. Others monitor Twitter posts to gauge public
sentiment.
The new survey approaches give some in the industry pause because they make
it harder to tell good research from bad. In ways pollsters don’t
fully
understand, the various methods seem to produce different results. In August
, for Donald Trump, surveys done online showed more support than phone polls
did; in September, it was Hillary Clinton for whom online polls produced
better numbers. | t*c
