The top is for Sagittarius for many reasons. The most important of all? That Sagittarius cannot contain what goes through his head or wanting it. A Sagittarius does not have complete control of his impulses, which causes him to let go of everything, everything, everything, what he thinks of the neighbor, what he thinks of his ex, what he knows about his best friend's friend. What to say, what not to say, a closely guarded secret and a painful truth.
Aries can't bite their tongue when they know they have to say something that is true. Aries does not know or want to hold back when faced with someone who deserves four well-spoken truths. Indeed, the truths of Aries are pretty powerful. Aries does know what it is to be a brutally honest person because Aries does not know how to be otherwise. It is as if a fireball forms in his throat when he wants to lie. It is as if he has something that hurts him inside, preventing him from shutting up.
Leo is very true to his essence, and his essence says that "lying is not living" Leo is not afraid of being a sincere person at all. What's more, Leo himself knows that he has made many enemies for that very reason, for not mincing his tongue and for saying everything he thinks. Possibly, many people who asked something in particular later regretted like nobody else for having done it.
Be careful with Virgo, very, very careful with Virgo, because their honesty is one of those that remain recorded for life. It is not burned, but it gives you a good blow because it is strong, firm, complex, and somewhat cold, like Virgo.
The intentions of people born lucky enough to be Virgo are never wrong. Never. Suppose a Virgo says something that is brutally honest and that hurts someone else. In that case, it is not because it was something premeditated or because it goes with a double edge. Virgo is not like that.
The only reason why Taurus is not a brutally honest person for all the hours and days of his life is straightforward: not to cause unnecessary wars.
Cancer, before being brutally honest with someone else, puts himself in the place of the person who will receive honesty in the form of an atomic bomb and is much more interested in what the other party may suffer than in telling the truth. Cancer thinks more about not hurting that person's feelings than about being a really frank person and letting each one manage as they can.
A Scorpio almost always knows what to say and what not to say. Scorpio is very temperamental, and yes, he can get carried away by the intensity of the moment and be a really rough person. Yes, it can drop giant pearls from its mouth; of course, it can, but Scorpio has a very clever and brilliant part. Scorpio always knows what to say to the person to talk to, how far it can go, and what it really wants to get with that conversation.
Capricorns are people of few words; however, when they speak, they SPEAK, and no, they do not do so very subtly. Capricorn does not fall within the top of the most brutally honest signs because, honestly, it is even difficult for us to hear many phrases immediately from him, to hear many truths there, suddenly, very abruptly.
Aquarius only opens his shell and tells the truth when Aquarius thinks it is necessary. No more, no less. She will be brutally honest with who she should be, but she will never be because of the public request for starting some conflict or following someone's orders.
Libra has a hard time being a brutally honest person. It takes a lot for you to be the person to say something that might hurt someone else. Libra does not lie, but there are many times that it omits very crucial information so as not to cause harm or unnecessary wars. You only do it when you know you can make someone happy. He only does it to protect others. Surely Libra will do much better saying what he thinks and letting go of everything he knows. Still, his conscience and his sorrow for having been the person who has caused a conflict would not let him sleep at night.
Pisces, a sincere person, has the same as an extremely organized person. I mean, nothing at all. But beware, this is not a directly poisoned dart for Pisces, quite the opposite. Pisces cannot be a sincere person because Pisces always puts the feelings of others first.
The last place is Gemini, and no, this does not mean that Gemini is the most liar person in the zodiac. He's screwed up for being extremely honest with compassionate people. Evidence can corroborate this: Geminis have screwed up many times for saying things they did not have to say.
