Try this on for size. Would an INTP really give a shit about any of this? This is STJ micro-management at its very worst.
This was a letter to his daughter Patsy.I do not wish you to be gayly clothed this time of life, but that what you wear should be fine of its kind; but above all things, at at all times let your clothes be clean, whole, and properly put on. You will be the last who will be sensible of this. Some ladies think they may under the privileges of the dishabille be loose and negligent of their dress in the morning. But be you from the moment you rise till you go to bed as cleanly and properly dressed as at the hours of dinner or tea. A lady who has been seen as a sloven or slut in the morning will never efface the impression she then made with all the dress and pageantry she can afterwards involve herself in. Nothing is so disgusting to our sex as a want of cleanliness and delicacy in yours. I hope therefore the moment you rise from bed, your first work will be to dress yourself in such a stile as that you may be seen by any gentleman without his being able to discover a pin amiss, or by any other circumstance of neatness wanting.
Here's some stuff from another letter (written when he was younger) that he sent to a friend who'd asked him for advice on what he should read during his legal studies.
Before 8 a.m., "Employ yourself in physical studies, Ethics, Religion, natural and sectarian, and natural law." From 8 a.m. to 12 p.m., he suggested reading in law, and from 12 to 1, politics. Then the afternoon would cover history, and "From dark to Bed-time," belles-lettres, criticism, rhetoric, and oratory. (Taken from pp. 63 of "Thomas Jefferson: an intimate history by Fawn McKay Brodie.)
This stuff shows that he was a fastidious, methodical, detail-whore. Do those traits not strike you more as STJ than NTP? (I am discounting INFJ because I REALLY do not think he was an F of any sort.)
