The Legacy Act in Northern Ireland provides a conditional amnesty for people who committed crimes during the Troubles, as part of a broader process of reconciliation. It’s an attempt to draw a line under events of the past, but it’s generated anger among the families of some victims, who feel they’ll be denied justice. When things go wrong, we need to find people to blame. Who’s responsible? Who should be punished? But might we do better if we were prepared to blame less – prioritising the truth, and forgive more? It's been proposed that the NHS adopts a no-blame system where staff don’t lose their jobs if they admit a failure, so the NHS learns quickly from its mistakes. The “no-blame culture” idea already exists in parts of the US aviation industry where people are encouraged, even praised, for owning up to mistakes that could cost lives. If blame means disgrace and the end of a career, it’s hardly surprising that people hide the truth about their own failure. How many of us would admit it quickly, if we discovered that a mistake at work had led to terrible consequences? More forgiveness might lead to greater openness and honesty. It could make it easier to avoid mistakes being repeated. But is it moral to forgive serious wrongdoing? Where is the justice in that? Surely the fear of blame is a powerful incentive for us all to do our jobs properly and avoid mistakes. Do we need more forgiveness – or less?
