Young Man Using Smartphone At Home With Plants

Most of us have something about us that we’re not 100% in love with—an impulsive streak, perhaps, or a short temper. What if those personality traits could be modified with daily use of a smartphone app? That was the focus of a new study from an international research team led by the University of Zurich, published in Proceedings of the National Academy of Sciences.

Changes that were noticed by friends and family members were mostly in participants who wanted to increase expression of a certain personality trait. On the other hand, the people close to those who wanted to reduce expression of a personality trait noticed little change.

But it’s important to note that the group who wanted to reduce expression of a personality trait mostly wanted to become less emotionally vulnerable—a primarily inner process that’s not always easy to observe from the outside.
