Is Zodiac Compatibility Complete BS, Or What?

Star-crossed lovers, or something like that

Relationships all boil down to one thing: compatibility. Does everything you are work well with everything your S.O. is? It would be great if there were a tried and true way of testing the waters without flirting with the idea of heartbreak. Of course, there are ways to get more insight into your relationship. Some use those kitchy love calculators the internet plays home to, while others consult the zodiac, because the stars don't lie. (Or do they?)

Certain signs work better with certain signs. Any individual with access to a tabloid magazine or the internet knows this to be (maybe) true. But, really, how true is it? Astrologer Christie Craft tells us zodiac compatibility runs so much deeper than sun signs. Having your star charts read isn't a casual after work event, though. So, for the majority of us, taking into account our sun sign is as close as we'll get. With that said, relationships are complex and the zodiac doesn't hold all the answers. It can be a guide, though—for fun or for real. We spoke with four couples: two who challenge the zodiac compatibility chart (below), and two that fall within it, to find a not-so-scientific answer to the age-old question of how valid zodiac compatibility really is. Turns out, it's complicated. Thanks, stars.

Key

Aries
Compatibility: Aries is a fire sign, so they like other fire signs like them (Leo and Sagittarius especially, as well as other Aries). They also get along well with air signs like Gemini, Libra, and Aquarius. 
Incompatibility: Earth and Water signs tend to extinguish fire, so Aries isn't super compatible with Taurus, Capricorn, or Virgo (Earth signs), or Cancer and Pisces.
Wild card: Scorpio. Because Aries shares a ruling planet with Scorpio—Mars, the war god of action—sometimes these two will make great friends and lovers. But Scorpio is still a water sign, which makes this match unpredictable.  

Taurus
Compatibility: Taurus is an earth sign, so they are best with other earth signs (Virgo, Capricorn, other Taureans). Water carves and soothes earth, so Pisces, Cancer, and Scorpio are great matches.
Incompatibility: Fire scorches earth, so fire signs like Aries, Leo, and Sagittarius are far too dramatic for easygoing Taurus. Air dusts up earth and creates confusion, so Aquarius and Gemini are said to be incompatible. 
Wild card: Libra. Though an air sign, Libra shares a ruling planet with Taurus (Venus), so they sometimes work! 

Gemini
Compatibility: Fire intrigues air, so Aires, Leo, and Sagittarius are their best matches—along with other air signs, like Libra, Aquarius, and other Geminis. 
Incompatibility: Air evaporates water, so signs like Pisces, Cancer, and Scorpio don't work well with Gemini. Earth and air create dust storms, so typically, Taurus and Capricorn don't work.
Wild card: Virgo. They couldn't be more opposite, but they do share Mercury as a ruling planet. 

Cancer
Compatibility: Cancer is most compatible with other water signs: Scorpio, Pisces, and other Cancers. Earth signs, like Taurus, Virgo, and Capricorn, are also very compatible. 
Incompatibility: Fire signs, like Aries, Leo, and Sagittarius, do not work well; neither do air signs Aquarius, Gemini, and Libra.

Leo
Compatibility: Leo goes well with Aquarius, Gemini, and Libra, as well as other fire signs, like Aries, Sagittarius, and other Leos.
Incompatibility: Leo doesn't work well with water signs, like Pisces, Cancer, or Scorpio. Same goes for earth signs Taurus, Virgo, and Capricorn.

Virgo
Compatibility: Virgo likes other earth signs, like Taurus, Capricorn, and Virgos, as well as water signs like Scorpio, Cancer, and Pisces. 
Incompatibility: Virgo won't jive with fire signs, like Leo, Aries, and Sagittarius, as well as air signs like Gemini, Aquarius, and Libra. 
Wild card: Gemini, as these two share Mercury as a ruling planet. 

Libra
Compatibility: Air signs get along well with fire signs, like Aries, Sagittarius, and Leo. They also get along well with other air signs (Gemini, Aquarius, other Libras). 
Incompatibility: Libras do not get along well with most earth signs like Virgo and Capricorn. Same goes for water signs Scorpio, Cancer, and Pisces. 
Wild card: Taurus is a wild card because they share a ruling planet—the gentle Venus.

Scorpio
Compatibility: These are the dry water signs, so they like earth—especially Taurus, Virgo, and Capricorn. They get on famously with other water signs, like Pisces, Cancer, and other Scorpios (though when two Scorpios get together, it's like a sex scene from True Blood.)
Incompatibility: Air signs, like Gemini, Aquarius, and Libra are no-nos. Fire signs actually can work with Scorpio because of their fiery nature, but typically Leo and Sagittarius are known to set Scorpio’s seething temper ablaze. 
Wild card: Aries. Scorpio shares Mars as one of its dual ruling planets with Aries, so sometimes these two make amazing friends and loyal and hyper-protective partners. 

Sagittarius
Compatibility: Sagittarius goes well with Aquarius, Gemini, and Libra (air signs), as well as other fire signs, like Aries, Leo, and other Sagittarians.
Incompatibility: Sagittarius doesn't work well with water signs, like Pisces, Cancer, or Scorpio. Same goes for earth signs Taurus, Virgo, and Capricorn.

Capricorn
Compatibility: Capricorn likes other earth signs, like Taurus, Capricorn, and Virgo, as well as water signs like Scorpio, Cancer, and Pisces. 
Incompatibility: Capricorns butt heads with fire signs, like Leo, Aries, and Sagittarius, as well as air signs, like Gemini, Aquarius, and Libra. 

Aquarius
Compatibility: Aquarius loves other air signs, like Gemini, Libra, other Aquarians—they also get along fantastically with fire signs Leo, Sagittarius, and Aries. 
Incompatibility: Aquarius doesn't do well with water signs, like Scorpio, Pisces, and Cancer. Nor do they get on with earth signs, like Virgo, Capricorn, or Taurus. 

Pisces 
Compatibility: Pisces is compatible with other water signs, like Scorpio, Cancer, and other Pisces—as well as earth signs, like Taurus, Capricorn, and Virgo. 
Incompatibility: Pisces is not good with fire signs, like Leo, Aries, and Sagittarius. Nor are they good with air signs, like Gemini, Libra, and Aquarius.
