In this day and age, it is not unusual for people to have false misconceptions about people who inject ink under their skins to create tattoos. The fact of the matter is, many people who wear tattoos are just like everybody else, except they are bold and daring enough to make a self expressive statement of who they are and what they strongly believe in.
Depending on the social group you may find various points of view and some groups are more radical than the others. In some societies or tribes however tattoos are "mandatory" and are a sign of belonging to a tribe or a gang.
Many people attempt to search into the psychology behind people who wear tattoos, often even presuming that those who have tattoos are rebellious or have hailed from dangerous, unfavorable pasts.
Contrary to this notion, people who wear tattoos more often than not have them because they have in depth meanings to those people. On the other hand in many cases it is just a bodyart. No matter what they show or mean to an individual they are a deeply personal thing for most tattooed people.
Tattoos become deeply "multidimensional" for the people who get them to commemorate their dearly beloved.
Psychologists often try to get into the psyche of people who wear tattoos, because for many years, it was believed that tattoo-wearers were prone to becoming criminals or had negative pasts. It is important to take note that while some criminals do have tattoos on them, so do more and more normal citizens.
It is, therefore, not always right to look at tattoos in a psychological light. Just because more people are sporting tattoos nowadays does not mean our society is in shambles in any way. Tattoos have simply gained popularity as a social novelty and as every trend this one may slow down with time.
When analyzing tattoos, you should analyze the meaning that goes with them on a personal level. Very often you can use tattoos to "read people" because tattoos can give you a lot of information about the person who is wearing them.
Tattoos can appear scary at times, but it is important for us to remember that the person may have gotten the tattoo at a different point in his or her life. They do not always serve as indicators of who the person really is inside.
It's never good to judge people anyway, especially by the color of their skin, regardless how many colors it has.
