Do you think 10 charts will be enough? Maybe as a preliminary study, but ideally a huge database of hundreds or thousands of charts would be more useful. However I understand the inevitable resource constraints. Someone should start an ASC-Astrology database where diagnosed and self-diagnosed individuals upload their (verified) birth times and some demographic and life details - both quantitative and qualitative. Unfortunately you may only get those who are open-minded about astrology responding, so a biased, self-selected sample!
Jupiter rules Sagittarius so that would support my hypothesis. In astrology, there are four mutable signs: Gemini, also an air sign; Virgo, an earth sign; Sagittarius, a fire sign; and Pisces, a water sign. The term "mutable" is a quality assigned to a sign. There are three qualities, such as mutable, cardinal and fixed.
Your hypotheses sound interesting. You haven't said which directions they might go in so here are the questions that come to mind about them:
What would constitute afflictions to the Ascendant? How are you going to operationalise this? Square Saturn maybe or Opposition Uranus? Wouldn't NTs be just as likely to have these?
Moon = emotions, so what do you suppose is different about the emotional responses of ASC individuals? That they have less emotion following the stereotype that they are more logical, like robots?
Mercury = mind - are you hereby tapping into the systematising hypothesis about ASC minds? Surely not all ASC individuals view the world through the intellectual modality, even if they have to rely on logical faculties to take the place of the missing social-political circuits in the mind.
Mars = aggression. It would be interesting to know what your theory is about ASC individuals and their aggression.
Or have I simplified their symbolism here too much? I'm just keen to learn more!
Yes, 10 charts is a very small sample. I love the idea of a database! As mentioned in another post, it indeed is enough for the purposes of my class and I am organizing it to be a gateway study into further inquiry. Later on I will include famous HF autists, self-diagnosed, as well as suspected but undiagnosed to see where there may be correlations with the diagnosed study (or not!).
"Why then do you say you think the mutable signs *aren't* involved?"
I'm sorry I wasn't clear, I used a double negative with "aren't." I will definitely be on the lookout for the involvement of the mutable signs precisely because of their rulerships.
The Vedic system is very different from the Western system, although anciently they have the same origin. Afflictions to the ascendant will be harsh aspects (defined differently in the Vedic system) to the ascendant itself or to the ascendant lord. Yes, many NT people have such afflictions, which is why I'm going to look for several factors in several layers and see if their are any relationships/patterns between charts. It's true, I'm not sure what I will find! I hope to find something that differentiates what NT people experience, but I really don't know.
In your example of the Moon, I am not looking for a lack of responsiveness per se, or a robotic, overly logical orientation as opposed to emotional. I just want to know what is happening for the Moon (Mind - which in VA also includes the emotions and social relationships), are there afflictions that alter the expression of the Moon (aspects by Saturn Mars or the North Node, combustion)? Are there yod type aspects with the Asc. and Asc. lord that don't let the emotions come through to the outside world? Is the Moon found in detrimental house that makes it more difficult to express? Combinations of the above? How does the Moon express in the divisional charts? Which Nakshatra is it in? Which Nakshatra is its opposite? This is an example of some of the questions I will be asking myself. I will have similar approaches with Mercury, Jupiter and Mars.
