邦訳：2025年7月・日経BPShigehiro Oishi is the Marshall Field IV Professor of Psychology at the University of Chicago and one of the foremost authorities on happiness. Life in Three Dimensions explores the shortcomings of happiness and meaning as guides to a good life, pointing to complacency and regret as a "happiness trap" and narrowness and misplaced loyalty as a "meaning trap". Psychological richness, Oishi proposes, balances the other two, offering insight and growth spurred by embracing uncertainty and challenges.
