From New Scientist

New Scientist reports that engineers in the UK are working on a sort of “fear detector” which will enable amusement park rides to automatically adjust based on the level of excitement riders want to experience.

New Scientist explains:

A human operator can see a person’s heartbeat and facial expression and hear their reaction via a display, and use that information to control the motion of the ride.

The team is studying how the physiological data correlates with the emotions a person reports experiencing during a ride. Knowing how to tell when a person is having fun, bored or fearing for their life could make it possible to have rides automatically alter their behaviour to give the best possible experience. For example, the individual cars of a roller coaster could each deliver a ride customised to the occupants.

People at the same meeting paying attention to different details of a shared event

The Unreliable Witness

We tend to think memory is where our account of an event becomes unreliable. But the process begins earlier. Attention is selective, perception is incomplete, and two people can experience the same event while noticing very different things.

Deciding Under Constraint

The data is good. The model is sound. And the decision still doesn’t hold the way it should. The problem isn’t the analysis. It’s what the analysis assumes about the stability of the world it’s describing.

Why Institutions Feel Slower Than the World Around Them

The frustration with institutions isn’t wrong. But the explanation usually is. The problem isn’t political will or institutional timidity. It’s a design built for a world that no longer exists.
