After having read a fair survey of forum posts and topics, I notice that it's common for us to extrapolate all sorts of things from type. This tendency to read type into every aspect of a person's life is likely a distortion of the way people really work, if not outright incorrect.
For example, there are many factors that typing simply cannot take into account.
Intelligence is not a function of type (though test-taking ability may have a limited correlation). Likes, dislikes, and desires are only partly linked to type. Type does not account for acculturation, training, or life experience. Type does not correlate with physical or mental pathology.
Yet all of these things can and do influence an individual's decision-making process.
What are other ways in which personality typing is limited?
