Traditional rating

Read off the angle between the two signs, not off an opinion. The same rule sets all 78 ratings.
The angle
Quincunx, 150°
150°, sharing no element, mode or polarity. Classical texts read it as the hardest angle to translate across.
Element mix
Fire and Water
Aries is cardinal fire under Mars; Scorpio is fixed water under Mars (trad.) / Pluto (mod.).

Aries and Scorpio, in brief
Before modern astronomy handed Scorpio to Pluto, Mars ruled both Aries and Scorpio. They keep the same traditional day, Tuesday, and the same traditional numbers. On paper that should make them near-relatives. On the wheel they sit 150 degrees apart, sharing no element, no mode and no polarity, which is the least compatible geometry the system produces.
Hellenistic astrologers had a blunt word for signs in this position. They said such signs cannot behold each other, that they are in aversion, and they meant it structurally: with nothing in common on any of the three classifications, there is no shared category to argue inside. Later astrologers softened the reading to adjustment, the idea that a quincunx never resolves but does keep correcting itself. Both readings point at the same experience of never quite finding the common vocabulary.
The shared ruler is the real story. Mars in Aries is Mars uncovered: fast, hot, visible, over in a minute. Mars in Scorpio, in the traditional scheme, is the same drive with the exhaust routed inward, slow, patient, deployed at a time of its own choosing. Aries is cardinal fire and yang, Scorpio is fixed water and yin, so the identical fuel produces almost opposite behaviour. Their number lists match exactly, 9, 18 and 27, each reducing by digit sum to 9, the number classical numerology assigns to Mars. It is the same inheritance, and it is the only thing on the page these two hold jointly.
Love, friendship and work
Love & attraction
The attraction gets described as immediate and hard to explain, which fits the shared rulership better than the shared angle. Both signs are absolutist about desire. Neither does lukewarm, neither is embarrassed by wanting something, and both would rather have a difficult relationship than a mild one. What they disagree about is disclosure. Aries states the position and considers the matter handled. Scorpio watches, gathers, and reveals a position only once it can no longer be used against it.
That difference in timing is where the trouble accumulates. Aries reads Scorpio's silence as either agreement or sulking, and is wrong on both counts. Scorpio reads Aries's openness with other people as carelessness with something Scorpio treats as sworn. Astrologers describe jealousy as this pair's classic pressure point, but the mechanism is narrower than jealousy: one sign believes trust is proven by saying everything immediately, the other believes it is proven by choosing carefully what to say at all.
As friends
Outside romance the angle is easier, mostly because there is less to renegotiate. Aries respects Scorpio's refusal to be intimidated, which is rare in Aries. Scorpio respects that Aries does not manipulate, which is rarer still in Scorpio's estimate of people. Neither friend will offer comfortable reassurance, so advice between them comes back accurate and unpadded.
The friendship goes wrong slowly rather than loudly. Aries expects to be told when something is off; Scorpio expects to be understood without saying. Months of that produce a Scorpio who has quietly downgraded the friendship and an Aries who has no idea anything happened. Aries then finds out all at once, which is exactly the mode of delivery Aries handles worst.
Working together
Professionally the pair works better than the score suggests, provided nobody has to report to anybody. Aries opens ground fast and does not much care whether the first attempt is correct; Scorpio finds the pressure point, waits, and closes. Trouble arrives with a shared budget or a shared credit line, because both signs treat a concession as a precedent. The quincunx is the aspect classical astrologers were least interested in, having no formal geometry for it, and modern readings mostly amount to advising the two parties to keep separate territory.
Where it goes wrong
The signature argument is about whether an argument has ended. Aries raises the voice, says the worst thing available, feels better, and considers the file closed. Scorpio said very little, retained all of it, and did not close anything. Six weeks later a version of the same sentence returns with specifics attached, and Aries genuinely does not recognise the incident being described. Nothing about the shared Mars fixes this, because Mars is what makes both of them unwilling to be the one who yields first.
The second failure mode is speed against strategy. Aries commits publicly before checking, then needs somebody to make the commitment survive contact. Scorpio can do that and resents being handed it. Scorpio, in turn, holds information back that would have changed what Aries did, on the reasoning that Aries would have mishandled it, and Aries experiences this as being managed. A score of one out of five is an honest reading of the angle rather than a prediction about two people. The tradition rates the geometry; it has never rated anyone's actual relationship.

Aries & Scorpio — frequently asked
In traditional astrology, yes. Mars ruled Aries by day and Scorpio by night in the classical scheme, and both signs kept Tuesday as their day. Pluto was assigned to Scorpio only after it was found in 1930, which is why most modern sources list two rulers for Scorpio and one for Aries.
Because the numbers follow the planet, not the sign. Both lists are 9, 18 and 27, and each of those reduces by digit sum to 9, which classical numerology gives to Mars. It is a shared inheritance rather than a signal about the pair, and it does not make any number better odds at anything.
Different, not automatically worse. A square is a collision between signs that at least share a mode, so both parties recognise the fight they are having. A quincunx shares nothing, so there is no agreed frame at all, and the classical texts largely declined to treat it as an aspect.
Agree on a rule that anything unresolved gets named within a week. This pair's damage comes almost entirely from one side archiving what the other side has already forgotten.
