An analysis of the world model used for The Limits to Growth in 1976 by mathematicians Vermeulen and De Jongh has shown it to be "very sensitive to small parameter variations" and having "dubious assumptions and approximations".[30]

In 1973, an interdisciplinary team at Sussex University's Science Policy Research Unit reviewed the structure and assumptions of the models used and published their analysis in Models of Doom, finding that the forecasts of the world's future are very sensitive to a few unduly pessimistic key assumptions.The Sussex scientists also wrote that the Dennis Meadows et al.methods, data, and predictions were faulty, that their world models (and their Malthusian bias) did not accurately reflect reality.[31]

Economist Thomas Sowell, in his 1995 book The Vision of the Anointed, describes economist John Kenneth Galbraith, biologist Paul R. Ehrlich, the Club of Rome and Worldwatch Institute as "the anointed", declaring that "they were utterly certain in their predictions, yet completely disproven empirically, though their reputations remained perfectly undamaged".
