News: This is the age of paranoia, scientists say - Telegraph

Who are you calling paranoid? One in four of us regularly has paranoid thoughts, according to research from the Institute of Psychiatry. The Telegraph (20 October 2008) article quotes Dr Daniel Freeman from King's College London: "Social isolation, a frequent drawback to urban life, is closely associated with paranoid thoughts. In the UK nearly four times as many people live alone than 50 years ago. Increasing paranoia is certainly one more challenge posed by galloping urbanisation."
