In addition to being a psychologist and corporate consultant, Furnham (University College, London) writes journal articles and scholarly books at a ferocious pace as well as regular columns in the Daily Telegraph and The Sunday Times (not to mention his contributions to the BBC). This collection of more than 60 brief and breezy essays, which he describes as ''a sideways glance at managing people,'' is handy for busy executives dipping into the work at airports and in taxis. The essays explain what business can learn from psychology in an encyclopedia of management topics from aging and anxiety to whistleblowers and workplace romance.
