The Jimmy Savile scandal is a textbook example of wilful blindness. It viscerally underlines the necessity for leaders to free up tacit knowledge in their organisations.
The BBC is not alone in facing questions about how it allowed a predatory paedophile to conduct a career of child sexual abuse stretching over decades – apparently to the knowledge of colleagues around him. The NHS, the police, sundry care homes and approved schools among others also have to account for apparent failures in their duty of care. But the BBC holds a special responsibility, having provided the platform upon which Savile built his celebrity as a family entertainer and sustained his powerful influence over vulnerable people. Such is (or was) the trust in the BBC that the halo effect it conferred over Savile possibly encouraged others to drop their guard.
