Deliberate cruelty to animals. Not only is it reprehensible in and of itself, the animal can't tell anyone what happened. What does that tell you? Would you trust a person who chose to inflict harm upon a weaker creature, especially one who can't talk about what happened? RFlagg - I can't remember the original question, but at any rate, now it includes both physical and personality, more or less. I'm not sure I can imagine a physical trait that would make someone seem untrustworthy. The classic - shifty eyes - is more an indication of shyness, in my book, or perhaps depression. I don't believe such a trait exists, since the physical is either genetic or a manifestation of personality, emotion or individual taste.

I find the inability for someone to look you in the eye when talking to you a "red flag" that they are not to be trusted.

Lateness and laziness. They are the least likely to be trustworthy and reliable

People who say horrible things about other people to you. They are usually multi-faceted, superficial and/or shallow. Not very good qualities to have in someone to trust.

As for manerisms and physical traits of a person not to trust, unless some one is mentaly ill and feels no compuction at lieing then they'll tend to have their hands in loose fists, most of the time, they will generaly blink alot, and some will grin or chuckle a bit more than is normal.(That last one does'nt apply to people who tell stupid jokes or just laugh at odd times, their just a little crazy.)

I have found that lack of compassion often means the person is self centred and cannot be trusted.

If a person brings up (especially if it seems inapropriate to do so) how they have pure motives, or about how they are honest, or (in the case of a salesman) how little money they are making on this deal.

The small G on their license plate.

People who don't make eye contact. They are lying, or have something to hide

I can't give any specific ideas of why or why not to trust people. Honestly, I believe that everyone is a six-sensory being and if you learn to trust your sixth sense, or intuition, you should be fine. Some people can easily tell who is lieing to them just by a vibe or feeling. Trust these. They're not there by mistake and you're not imagining them. They are your intuition trying to speak to you and let you know that this person is not to be trusted.

When he or she cant look you in the eye's when he is speaking to you and talks about other people behide their back coz if he can talk to you about another person He can talk to another person about you.And people who seek a lot of attention because they are most of the time willing to do anything to get that attention.

Averting of the eyes. Many people (subconsiously and unbeknownst to themSELVES) find it difficult to look people in the eye when they are lying. Hence the famous characteristic of Detective Gorem in Law and Order: Criminal Intent. He finds himslf bending over sideways, making a near-horizontal line of his upper torso to look into someone's face. He wouldn't have to do that if they were looking him in the eye in the first place. (God he is sexy in that character.)

the type of person that says "trust me" you can pretty much be sure you can't trust them. Ironic eh?

The number one indicator is when someone is suspicious of you. If you encounter such a person, you'd be illadvised to ever trust him or her.

A deranged mind- like they can't stop talking about weird things.

Two I know of that are big warning lights. 1. People who immediately upon meeting you, quickly and easily smile at you, overtly so sometimes and sometimes accompany this with apparent courtesy and good social manners, especially if there are other people around. This is designed to disarm your defences and allow them to do what they have in mind, undetected, until its too late to fight back (women everywhere, especially - beware). 2. People who arrive late for a meeting, etc. (more than a few minutes) who don't call in plenty of time to stop you wasting your journey/time and who then don't call until a long time after the meeting time. This sends the message that "your time is less valuable than theirs".

Thin lips are a good indicator of someone who is mean or not generous with either themselves or what they give. It also makes kissing a little bit of a disappointment.

When they rattle on about how it's all about them ! The way they treat there parent's and animal's !! -- And their eye's -- Run Fast

Someone who consistently doesn't look you in the eye while talking to you.

when they tell you things that are 'too good to be true'. I knew someone who had confessed to stealing money, but he had given it to a woman who ran a shelter for AIDS babies. Yeah, right, Santa Claus. He kept it.

When a person is saying something that is too good to be true.

People who only want to talk about themselves... be it their problems, their successes, or what they ate for breakfast. ESPECIALLY a person who constantly has dramatic problems which they always say is someone else's fault.

nicce question, hard to answer

Blood on their shirt and a knife in their hand. sorry but i trust all people till they give me good reason not to. (with caution of course)without me knowing their life story, maybe mistrust by others made them the way they are.

It is difficult to identify one trait but better, rather, to identify a pattern of traits and/or behaviors that indicate psychopathic/sociopathic people. These people represent 4% of our population by some standards. That is 1 in 25. They typically have 3 qualities: an absence of guilt for their hurtful ways, the inability to truly love and bond (unfamiliar with enduring emotions of love for another), and excessively talkative in a rambling sort of way that avoids important, deep feelings, though they may appear very logical. For more information see http://www.cassiopaea.org/cass/political_ponerology_lobaczewski_2.htm which is very heavy reading...Part II is most enlightening and a book named "The Sociopath Next Door" are two good resources. Recently Dear Abby reprinted her list of abusive characteristics which I found to be very useful: 1. pushes for quick involvement; comes on strong claiming "I've never felt loved like this by anyone." 2. Jealous; excessively possessive; calls constantly or visits unexpectedly. 3. Controlling; Interrogates you intensely, especially if you ar late, about whom you talked to and where you were. 4. Expects you to be the perfect mate. 5. Isolation; tries to cut you off from family and friends. 6. Blames others for problems or mistakes; it's always some else's fault if something goes wrong. 7. Makes others responsible for his or her feelings. 8. Hypersensitivity; is easily insulted, claiming hurt feelings when he or she is really mad. 9. Cruelty to animals or children; kills or punishes animals brutally. May expect children to do things far beyond their ability. 10. "Playful" use of force during sex. 11. Verbal abuse; constantly criticizes or says blatantly cruel things. 12. Rigid gender roles; expects you to serve, obey, remain at home. 13. Sudden mood swings. 14. Admits to hitting a mate in the past. 15. Threatens violence. Remember they don't have to have all these traits but if they show a tendency is a few, beware.

They appear to be on guard and impersonal.

Someone wearing an eye patch or possibly a cape could be a mysterious character. (unless they actually need the eye patch)

Anyone who starts a conversation with the words 'trust me' !

Someone who can't look you in the eye. With practice, you can tell more about a person by their eyes than anything else, period. I've gotten pretty good at it just by chance, my Dad's eyes could not make it clearer when he's telling anything even slightly untrue, even when he's kidding, and my Brother could lie perpetually without anyone ever being able to realize he's lying, so I had a few places to start from. Definitely eyes.

Probably coincidence, but men who have protruding foreheads are always nuts! At least every one that I have ever known... I actually read something on it once too, it escapes me at the moment.

someone who says "im the biggest liar in the world, quite possibly an even bigger asshole" when you first meet them should not be trusted .. haha, i learned the hard way .. also anyone who has shifty eyes, they're always up to no good

if they steal your wallet

Bad history

They keep bringing you gifts.

Their actions. Actions speak louder than words. This includes such things as: How they treat act around their family (respectfully?). Do they act differently in public than in private? Do they embarrass you in front of others? Do they do or want to do things that make you uncomfortable? Do you ever think someone else might question what's going on if they knew? Would your parents or siblings have any problems or issues? Are they a blabbermouth or gossip? When the matter of trust comes up, use common sense instead of your heart to figure things out. If you are a man, make sure you're using the big brain in your head and not the one between your legs. (Though I think in some men this is no improvement...) If a person's actions are speaking contrary to your core values, then their trust is suspect.

Somebody who tells you how honest they are.

A person that will not look you in the eyes, to answer your questions.

John Cleese hosted a BBC special on the human face, and it mentioned that even though there is no reason for it, it is almost universally true that if a person has eyes that are closer together than "normal", people will almost always conclude that they are less trustworthy.

that is easy...lying with out provocation.

No sense of humor. Small children and/or animals don't like him. Refuses to make eye contact.

one who posses the face of a date rapest

Watch their eyes, eyes are the window to the soul

When you ask a person a question, Watch their eyes. Do they look away and then answer and come back to you? Watch their hands, are they in front of you or tucked around them as though they are hugging themselves for the lie. Some people turn red. Especially if you ask them to repeat the lie.
