your personality, says study

An international research team led by the University of Zurich has shown that daily use of a smartphone app can lead to desired personality changes within three months. And three months after the daily interventions, the changes are still noticeable.
Personality traits such as conscientiousness or sociability are patterns of experience and behavior that can change throughout our lives. Individual changes usually take place slowly as people gradually adapt to the demands of society and their environment. However, it is unclear whether certain personality traits can also be psychologically influenced in a short-term and targeted manner.
Researchers from the universities of Zurich, St. Gallen, Brandeis, Illinois, and ETH Zurich have now investigated this question using a digital intervention.
In their study, around 1,500 participants were provided with a specially developed smartphone app for three months and the researchers then assessed whether and how their personalities had changed. The five major personality traits of openness, conscientiousness, sociability (extraversion), considerateness (agreeableness), and emotional vulnerability (neuroticism) were examined.
The app included elements of knowledge transfer, behavioral and resource activation, self-reflection, and feedback on progress. All communication with the digital coach and companion (a chatbot) took place virtually. The chatbot supported the participants on a daily basis to help them make the desired changes.
The majority of participants said that they wanted to reduce their emotional vulnerability, increase their conscientiousness, or increase their extroversion. Those who participated in the intervention for more than three months reported greater success in achieving their change goals than the control group who participated for only two months.
Close friends and family members also observed changes in those participants who wanted to increase expression of a certain personality trait. However, for those who wanted to reduce expression of a trait, the people close to them noticed little change. This group mainly comprised those participants who wanted to become less emotionally vulnerable, an inner process that is less observable from the outside.
"The participants and their friends alike reported that three months after the end of the intervention, the personality changes brought about by using the app had persisted," Mathias Allemand, professor of psychology at UZH said. "These surprising results show that we are not just slaves to our personality, but that we can deliberately make changes to routine experience and behavior patterns."
The findings also indicate that development of the personality structure can happen quicker than previously believed. "In addition, change processes accompanied by digital tools can be used in everyday life," explains first author Mirjam Stieger of Brandeis University in the United States, who did her doctorate at UZH. However, more evidence of the effectiveness of digital interventions is needed. For example, it was unclear whether the changes achieved were permanent or only reflected temporary fluctuations.
The present findings are not only interesting for research but could also find application in a variety of areas of life, the researchers said.
Should the report findings be used to create an app to boost social skills? We
