Flyvbjerg received his Ph.D. in urban geography and planning from Aarhus University, Denmark. He has written extensively about megaprojects, decision making, city management, and philosophy of social science. He was a member of the Danish Infrastructure Commission and a director of the Danish Court Administration. He has twice held the Fulbright Scholarship. Bent Flyvbjerg was knighted in the Order of the Dannebrog in 2002.
His research has shown that competition between megaprojects and their sponsors creates political and organizational pressures that leads to the consistent overestimating of project benefits and the underestimating of project costs. The best megaprojects do not get implemented, but rather the ones that look best on paper.
