Deeper could be better as far as conversations go, according to research from the University of Arizona. They got volunteers to wear a recording device which picked up their conversations over four days. The researchers analysed the participants' conversations to see whether they were trivial small talk or weightier discussions and the volunteers also completed assessments of their personalities and levels of happiness. Greater wellbeing was related to spending less time alone and more time talking to others. The happiest participants spent 25% less time alone and 70% more time talking than the unhappiest. However, the kind of conversation was also important and the happiest participants had twice as many deep and meaningful conversations and one third as much small talk as the unhappiest.
