Duncan Smith has become significantly involved in issues of family and social breakdown. He has stated his support for early interventions to reduce and prevent social breakdown. In December 2010, he studied a state-sponsored relationship education programme in Norway, under which couples were forced to "think again" and confront the reality of divorce before formally separating. The policy has been credited with reversing Norway's trend for rising divorce rates and halting the decline of marriage in the country over the past 15 years. Duncan Smith said he was keen to explore ways in which similar approaches could be encouraged in Britain. Officials pointed out that such a programme would be expensive but that an approach could reduce the long-term cost of family breakdown, which has been estimated at up to £100 billion. Duncan Smith said couples in Norway were able to "work through what is going to happen with their children", which has "a very big effect on their thinking". "Many of them think again about what they are going to embark on once they really understand the consequences of their actions subsequently," he said.
