Are dating apps turning us into narcissists?

What are dating apps doing to our mental health? According to one professor, they bring out behaviours which psychotherapists would have historically regarded as "slightly pathological and narcissistic." Psychotherapist Denise Dunne was talking to BBC online's Like Minds. So - are dating apps turning us into narcissists? Are they making us display pathological behaviours? Or is it all just a bit of fun, and should people lighten up? Vinny got the views of Naomh McElhatto,n the CEO of digital education consultancy Smart NI, and the man about town Chris Suitor.
