    Prediction, Regressions and Critical Realism.Petter Næss - 2004 - Journal of Critical Realism 3 (1):133-164.
    This paper considers the possibility of prediction in land use planning, and the use of statistical research methods in analyses of relationships between urban form and travel behaviour. Influential writers within the tradition of critical realism reject the possibility of predicting social phenomena. This position is fundamentally problematic to public planning. Without at least some ability to predict the likely consequences of different proposals, the justification for public sector intervention into market mechanisms will be frail. Statistical methods like regression analyses (...)

    Cost-Benefit Analyses of Transportation Investments — Neither Critical nor Realistic.Petter Næss - 2006 - Journal of Critical Realism 5 (1):32-60.
    This paper discusses the practice of cost-benefit analyses of transportation infrastructure investment projects from the meta-theoretical perspective of critical realism. Such analyses are based on a number of untenable ontological assumptions about social value, human nature and the natural environment. In addition, main input data are based on transport modelling analyses based on a misleading `local ontology' among the model makers. The ontological misconceptions translate into erroneous epistemological assumptions about the possibility of precise predictions and the validity of willingness-to-pay investigations. (...)

    Unsustainable Growth, Unsustainable Capitalism.Petter Næss - 2006 - Journal of Critical Realism 5 (2):197-227.
    This article argues that there is a fundamental contradiction between a profit-oriented economic system and long-term environmental sustainability. The ‘solutions’ that are proposed by mainstream environmental economists as well as their ‘ecological economy’ colleagues do not solve the central problems, but serve to further highlight the difficulties of changing capitalism towards sustainability. In a profit-oriented economy, capital accumulation is a prime driving force, and non-growth for the economy at large tends to result in serious economic and social crises. On the (...)

    What Kinds of Traffic Forecasts Are Possible?Petter Næss & Arvid Strand - 2012 - Journal of Critical Realism 11 (3):277-295.
    Based on metatheoretical considerations, this article discusses what kinds of traffic forecasts are possible and what kinds are impossible to make with any reasonable degree of accuracy. It will be argued on ontological and epistemological grounds that it is inherently impossible to make exact predictions about the magnitude of the ‘general’ traffic growth 20-30 years ahead, since many of the influencing factors depend on inherently unpredictable geopolitical trajectories as well as contested political decision-making. Due to the context-dependency of each particular (...)
