Timeline of the development of tectonophysics (before 1954) scheduled for mid 1912. So he hurried up to present his Continental Drift hypothesis. Mainly Charles Lyell, Harold Jeffreys, James D. Dana, Charles Schuchert, Chester Longwell, and the conflict with the Axis powers slowed down the acceptance of continental drifting . Timeline of the development of tectonophysics (before 1954) The evolution of tectonophysics is closely linked to the history of the continental drift and plate tectonics hypotheses. The continental drift/ Airy-Heiskanen isostasy hypothesis had many flaws and scarce data. The fixist/ Pratt-Hayford isostasy, the contracting Earth and the expanding Earth concepts had many flaws as well. The idea of continents
Drift hypothesis at supported the drift hypothesis, but when he examined them, he found their conclusions were "based on assumptions and methods that lacked empirical support." Another statement in Fox's study was, in studies done on social class and mental illness, "identify drift as an individual's downward intergenerational social mobility after the onset of mental illness, rather than as residential drift from higher to lower class status areas". So depending on what one's definition of drift hypothesis is, there will be data either to support or refute the validity of it. From an economic perspective of social class and mental illness, the
