There is around 7 years of research supporting the Constructed Development Theory as well as a doctoral degree. This page will host the research once it has passed through the Viva system.
In the meantime, please feel free to watch this talk I gave in Manchester recently as it describes my theory.
Although neuroscience was mentioned very briefly in the thesis, the next article goes some way to potentially reinforcing the principles of Constructed Development Theory as measured by the Thinking Quotient(TM) scale.
A collaboration between Darren Stevens and the authors of this paper would be necessary to determine which brain regions are active in those individuals who come out at TQ5 compared to those who come out at TQ9.
Watch this space for more research and the final thesis on Constructed Development Theory.
