In 2007, two Harvard researchers added a splash of balsamic vinegar to beer. 

When drinkers knew the beer contained vinegar, they hated it. 

But when the researchers told them “this is our MIT brew," the majority loved it. 

The study reveals the secrets behind marketing. 

On today’s episode of Nudge with award-winning science writer David Robson, we explain how good marketing can shape our perception.

96% of people reveal a bias when answering this question. And that bias makes marketing less effective, communication less engaging and products less appealing. 

Find out why in today’s episode of Nudge with the award-winning professor Leidy Klotz.

In December 2018 Gatwick Airport shut down. 109 eyewitnesses reported sighting 170 drone flights over the airport. 

All flights were grounded, and the nation braced for a terrorist attack.

But what if those sightings weren’t real but instead an imagination caused by expectations? 

In today’s episode with award-winning science journalist David Robson, we explore the science of the expectation effect.
