More regrettable is the number of people who confuse belief and the truth! Have you read ‘The Evolving Self: Problem and Process in Human Development’ (1982)?
Like many others before him, Kegan relies heavily on qualitative methods, such as the Subject–Object Interview, to categorize individuals into stages. These methods suffer from subjective interpretation and lack the measurement invariance or reliability that contemporary psychological science demands. Without validated, replicable tools with clear construct validity, claims about discrete developmental stages can only be called "speculative". The burden of proof lies with those promoting such frameworks to demonstrate that they outperform simpler, trait-based or dimensional models in predicting real-world outcomes.
It's a rare genius indeed who can pen a 6,000 word article and write off the life's work of so many other people in the process. Amazing!
Sadly, too many good people spend far too much time on bad theories.
