An anonymous reader quotes the Economist:
In its latest software release, Apple has made it possible for iPhone users to send all unknown callers to voicemail automatically.
Although the feature will no doubt prove useful to the millions of customers whose peaceful suppers are ruined by fake calls, it could be disastrous for the faltering public-polling industry. The challenges telephone pollsters face have been growing. Polling by phone has become very expensive, as the number of Americans willing to respond to unexpected or unknown callers has dropped.
Back in the mid-to-late-20th century response rates were as high as 70%, according to SSRS, a market research and polling firm. But the Pew Research Centre estimates that it received completed interviews from a mere 6% of the people it tried to survey in 2018. Although polls with low response rates can still be accurate, their costs increase dramatically as pollsters must spend more time and money calling more people.
