Mercury in astrology stands for the mind and intellect. In general, this planet is responsible for intelligence, learning abilities, way of thinking, logic and reasoning, as well as for any kind of intellectual connections and communication between people. Strong Mercury defines the most intelligent zodiac signs.

The energy of Mercury, depending on the circumstances, can be creative or destructive, but one thing is for sure: it will not let you get bored. Mercury makes your brain think, produce ideas, look for answers.

Another area of Mercury’s influence is trade transactions and monetary settlements. The influence of this planet in the natal chart contributes to the preservation of property and the multiplication of wealth.

By the way, you can attract or harmonize the energy of Mecury. The author of this article recommends the Mercury Talisman Pendant. If you experience communication or learning issues, or your Mercury is in the signs of Pisces, Sagittarius or Cancer (use this tool to check), the Mercury Talisman Pendant is an affordable way to effortlessly raise your vibes and recharge yourself with the positive energy of Mercury.

There is a difference in intelligence between people. Some people are cunning and insidious, others act intuitively; others are smart, but too trusting. What signs of the zodiac skillfully use their intellectual abilities, and who are naive and, therefore, reputed to be dumb?

We’ve ranked zodiac signs from least to most intelligent based on how their Sun sign blends with the energy of Mercury.


Pisces (19 February–21 March)

Pisces may sufffer from the fact that Mercury is in its detriment in their sign. Yes, they live in a world of illusions, they can make a mountain out of a molehill, their imagination is rampant. But they are not dumb at all. Lazy Pisces tend to go with the flow, so others do not always manage to recognize their erudition. Thanks to their resourcefulness, Pisces may still reach career heights. And they are creative as no other zodiac sign! Don’t forget to add extraordinary luckiness to this weird mix that compensates for their being the least intelligent zodiac sign.

Sagittarius (23 November–22 December)

Sagittarius is another weak sign for Mercury. Here, Mercury is rather a firestarter, than a lazy dreamer (like Pisces). The problem is that Sagittarians sometimes fail to think carefully before they act. Their plans can seem grandiose at the presentation stage, but the implementation phase may reveal a lot of shortcomings. They like to draw knowledge from books and have a theoretical framework in a particular area, but they are a bit hypocritical. Meanwhile, Sagittarians are leaders by nature and people tend to believe them whatever they say. Don’t forget that Sagittarius is the luckiest zodiac sign!

Taurus (20 April–21 May)

Tauruses are known for their heavy but steady and practical mind. Their intelligence manifests itself when it comes to the material sphere. Then, they turn on their worldly wisdom, carefully think and weigh everything. Of course, there are erudites among Tauruses, but they do not boast of their own knowledge in a particular area. They reach career heights very often, but not because of their mind. It is the result of their perseverance or support of influential friends.

Capricorn (22 December–20 January)

Capricorns are innovators and workaholics. By nature, they are smart, but this quality is used by them only half-heartedly. They are successful in their career thanks to their perseverance and love of work. However, they are not flexible in relationships: they can hardly accept someone else’s point of view. So, their personal life often leaves a great deal to be desired, as well as friendships. But, after all, they are the strongest sign of the zodiac!

Cancer (21 June–23 July)

Cancers are very sensitive and focused on their families. However, their minds are not flexible at all. They are slow to make important decisions. They back away. They often live in the past. However, they are very good at manipulating people, because they are cunning by nature and intuitively feel the psychology of people. They are able to achieve high goals, become leaders, since their mind is hidden under their shell.

Leo (23 July–23 August)

Leos are ostentatious erudites. They are superficial and not really focused. Usually, they know much less than they try to demonstrate to others. But their mind has the energy and drive to impress the world which is their stage. They are natural orators. Leos are able to achieve their goals using their charisma and the right people. The “king of beasts” does not need to know all the details.

Libra (23 September–23 October)

Libra vibrations blend well with the energy of Mercury. Libra is smart, intellectually refiend, but modest by nature. Their erudition is not flaunted. Having a great potential, they often do not know how to use it, and Libra poets usually remain unappreciated. Libra’s indecisiveness and trustfulness hinders them and allows others to manipulate or use them.

Aries (21 March–20 April)

Aries are smart enough, but naive. Sometimes, they allow themselves to be manipulated. Representatives of the fire element are very impulsive and quick-tempered. Aries express their thoughts accurately and deeply, and can benefit from situations in which another person would have given up long ago. However, there are few really brilliant intellectuals among the representatives of this sign. Their mind is a bit coarse.

Scorpio (23 October–22 November)

This is the first zodiac sign in the premier league of intellectuals in the world of astrology. Pure luck seldom comes to them. Scorpios are smart, with a well-developed intuition. Clever plans are their fortress, especially if it’s a matter of honor or revenge. Sometimes, they pretend to be simpletons and prefer not to demonstrate their intelligence. Scorpios make good teachers, but they can become anything.

Virgo (23 August–23 September)

Meticulous and petty, Virgos think out everything very carefully. They can learn all their lives. So, they often go on about the mind, not the heart. Virgo have a cold mind. They calculate everything: from the probability of success in any business to the probability of finding a suitable couple to start a family. Careerists. They may be violent in their pursuit of career advancement. Their natural intellect makes them insidious rivals and enemies.

Aquarius (20 January–19 February)

Aquarians are called the engines of progress thanks to their ruler Uranus, the planet of genius. Their way of thinking is different from the standard. They are creative and original in everything. They do not always find understanding among others. Let them often go against the crowd: they are aimed at high achievements in their chosen path. They are not always successful in their personal life, since they spend too much time on their hobbies. Many scientists and inventors, writers and artists were born under the sign of Aquarius.

Gemini (21 May–21 June)

Gemini is the smartest zodiac sign. From their early age, Geminis impress others with their wit and ingenuity. Yes, they can be experts in various fields, because they are extremely inquisitive. They have several talents, since the sign is dual. However, no matter what area of personal growth Geminis choose, they grasp all the nuances and achieve extraordinary results. They are enterprising and resourceful. Their bright intellect is their gift that compensates for some lack of focus which is the backside of their incredible mental abilities.
