Introduction to the Zodiac

Before we dive into which is the smartest zodiac sign, let’s look at what the zodiac is and review the key qualities for each sign. Astrology is an ancient study that involves looking at the alignment of the stars and planets on an assigned birthday to determine a person’s character traits. It has been used for centuries and is still a popular way to look at personality differences between individuals.

According to astrology, there are 12 zodiac signs, and each sign has unique personality traits. Aries is associated with passion and leadership, Taurus is known for being reliable and goal-oriented, Gemini is witty and has dual personalities, Cancer is sympathetic and intuitive, Leo is powerful and confident, Virgo is analytical and a perfectionist, Libra is diplomatic and peacemaker, Scorpio is loyal and dedicated, Sagittarius is creative and inquisitive, Capricorn is ambitious and responsible, Aquarius is progressive and independent, and Pisces is compassionate and artistic.

Astrologers Weigh In

To figure out which zodiac sign is the smartest, we turned to astrologers to get a better understanding of how intelligence is defined in astrology. According to astrologer Jessica Adams, intelligence depends on the willingness of a person to continually strive to learn and develop new skills. She points out that signs with Mercury as their ruling planet have an edge when it comes to smarts.

Ruling planet Mercury is associated with communication, logical thinking, and analytical skills. This means that the signs with Mercury in the seventh house, fifth house, and third house are more likely to be intelligent and quick-witted than other signs. This leaves Aries, Virgo, Gemini, and Aquarius as the smartest zodiac signs.


Aries is a cardinal sign and the first of all the star signs. This sign is associated with ambition, leadership, and independence, making this sign a natural born leader. Aries is also known for being highly intelligent, making them one of the smartest of the zodiac.

They have a great capacity for problem-solving and analytical thinking, and they often possess a great level of creativity when it comes to tackling a problem. Aries are willing to learn new skills and stay curious about the world around them, so they tend to stay ahead of the game when it comes to evolving their intelligence levels.


Virgo is an earth sign known for being analytical and logical. They have a great capacity for problem-solving and attention to detail, making them well-suited for any kind of analytical task. Virgos are perfectionists and they strive to continuously develop their skills, making them an ideal choice as the smartest zodiac sign according to astrologers.


Gemini is an air sign that is associated with dual personalities. This sign is known for being exceptionally intelligent, making them one of the brightest of the star signs. Geminis are skilled and creative problem solvers who are capable of looking at any situation and quickly coming up with the perfect solution. They love learning, and they often excel in the areas of literature, science, and mathematics.


Aquarius is an air sign and the last of all the zodiac signs. This sign is associated with knowledge, progress, and intelligence. Aquarians have an intense curiosity about the world and are never afraid to learn new things. They are quick thinkers and can come up with inventive solutions to any problem. These qualities make Aquarians stand out from their peers and make them the smartest of the star signs according to astrology.

Astrologers have studied the signs of the zodiac and their personalities at length to determine which is the smartest zodiac sign. The four signs that stand out above the rest are Aries, Virgo, Gemini, and Aquarius. Aries is associated with ambition and independence, Virgo is logical and analytical, Gemini is creative and witty, and Aquarius is progressive and intelligent. All these signs have the capacity to be highly intelligent, but they are the clear winners when it comes to being identified by astrologers as the smartest of the zodiac.
