‘We gave four good pollsters the same raw data. They had four different results.’

Nearly every polling articles mentions the “margin of error,” but what’s rarely explained is that the “margin of sampling error” doesn’t capture the potential for error in surveys, Nate Cohn writes. Two pollsters looking at the same raw data can come to widely different conclusions, Cohn says, because of the decisions pollsters have to make […]

When ad agencies focus on culture in the hiring process, a culture of exclusion can instead be created

Interview questions such as, “What’s your favorite TV show?” may seem innocuous: If you’re hiring someone, you might want to make sure they have things in common with other people at the company. But Shareen Pathak writes that ad agencies that have emphasized culture in the hiring process through similar questions are actually excluding people […]

‘Algorithms could save book publishing — but ruin novels’

Studying 5,000 book titles published over the last 40 years, Jodie Archers and Matthew L. Jockers have created an algorithm that can predict with 80 percent accuracy which novels will become bestsellers.

“Erasing racism through technology alone is impossible,” Kashmir Hill writes, but neighborhood social network Nextdoor found that a few changes to its interface reduced the number of racist posts significantly.

Two years after it was bought by Facebook, WhatsApp will start sharing user data including phone numbers with Facebook

When WhatsApp was bought by Facebook in 2014, users worried what the acquisition would mean for privacy on the platform. At the time, WhatsApp said the sale wouldn’t change anything: “We don’t know your birthday. We don’t know your home address. None of that data has ever been collected and stored by WhatsApp, and we […]

Clay Christensen explains his ‘jobs to be done’ theory: When we buy a product, we’re hiring it to help us do a job

Knowing more and more about their customers through data is often taking businesses in the wrong direction, Clay Christensen, Taddy Hall, Karen Dillon and David S. Duncan write. With so much information about their customers, businesses tend to lose sight of what actually gets people to buy their products. Christensen’s “jobs to be done” theory […]
