I disagree 100%. Do you think a man born in a traditional Arab culture would match the description for an IxFp? Or do you think a female ENTx would sound like the type description we have if she had been born in the colonial US? Maybe these examples aren't the best, but you get the idea.

Circumstances vary too much in a person's environment to ALWAYS use descriptions like those. Not everyone in the world fits into one of the 16 descriptions you know! Every sane person should, however, have functions that are ordered as one of the 16 functional analyses.

Someone with extreme circumstances in their upbringing most likely won't appear to be a stereotypical "type", and are likely to appear more like another type than most people would be.
