In June 2015 I travelled to Helsinki in Finland to act as an opponent in the public defense of the dissertation of Aman Dhir at the University of Helsinki. Recent decades witnessed a rapid increase in the development of technology and the use of the internet and specific applications, such as Facebook, Twitter and WhatsApp. Experts have argued that improvements in the well-being of people do not result despite such advancements. The question arises how the use of technology and the internet can make a positive difference in people’s lives. How do we understand internet addiction? What are the consequences? How could internet applications be designed that will curb addiction? How could internet applications build positive engagement and build resilience against addiction?
