A few questions I have about the psychometric tool of MBTI.
In the simplest term, it tries to tap into an individual's preference for certain attitudes/functions, while assuming mutual exclusivity b/w binary functions.
Oh ya, and, even though binary, there's still a degree of preference.
Then, functions are ordered in a heirarchy of preferences, with one function aiding another from a different binary category...and so on and so on...until the 8th order.
..to finally give us...the BIG PICTURE.
If typing personality (which, to me, is about how we utilize our cognitive and motivational processes to predict a scheme of behavioural patterns) integrates what is IN our minds, to, what we ARE/DO/COULD BE...
....where is the bridge between the mind to the matter?
Meaning, how confident are we in the underlying assumption that behavioural outcomes are in line with cognitive and motivational processes?
Can we never think of instances where our behaviour contradicts our cognitive and motivational processes (e.g., influence of environment)? Most radically, can a person be truly type WXYZ but *prefer* and even test as type ZXWY due to the *some reason*? (e.g., behavioural conditioning not favouring their 'true' type)
So, how 'core' is personality? How valid and reliabile is measuring cognitive and motivational processes to predict behaviour?
Simply, my burning curiosity is how we explain how we get from the 'inside' (mind - cognition, motivation) to 'outside' (behaviours manifested)? What's the story of the yellow brick road that leads us from the inside to the outside?
Maybe, the simplest explanation is that, as with any reductionist model, the whole may very well be greater than the sum of its parts....and in that, lies the answer.
