In our day to day lives, we often use different terms to describe ourselves or others around. These terms often fall under the psychological field and more times than not, the words we use to describe actions, personality, and so on are used incorrectly. Below is a list of some of these terms and their proper definitions.
1. Obsessive Compulsive Disorder (OCD)
We have all heard, or even said, "I'm so OCD when it comes to organizing. I'm such a perfectionist." However, Obsessive-compulsive disorder roughly affects 2.3% of the population. To put into better terms that's roughly every 1 out of 40 adults or 1 out of 100 children. The general population tends to believe that OCD simply means someone is a perfectionist, is very orderly, neat and so on. However, OCD is when someone has an excessive thought that can lead to an excessive behavior to clam said thought. For example, someone is afraid they did not turn off the light, so they constantly check light switches. Now that may seem simple and no big deal but the obsessive behavior can have a real impact on one's life, health, and relations.
2. Psychopath
Usually, when someone seems off to us, we often refer to them as "oh they are a psychopath." When we refer to someone as a psychopath it's usually because of unwarranted behavior that did not sit well with us, or they simply are pegged as the 'weirdo'. Other times, we see a killer on the news being tried and we refer to them as psychopaths as well. However, psychopaths, or anti-social personality disorder, are not as common as we think. About 3% of men and 1% of women are inclined to have this disorder and most psychopaths are not murders. More commonly, you will see them in high position jobs.
3. Neurotic
The word neurotic, or neuroticism, has changed its definition a few times in psychology and has made its way into everyday language. When used it's often meant to be an insult. However, the original use of describing someone as "neurotic" was to describe someone that was distressed with emotions, such as someone with high anxiety. It then turned into the terms known as neuroticism, which simply characterizes people with anxiety, moodiness, jealousy and so on. In the day to day language, it's used to degrade people who often share characteristics of anxiety or depression. In reality, we should not degrade someone for exhibiting signs of anxiety or depression, we should be assisting them through it. But we really should not be calling someone a term, if they do not accurately depict the term in its entirety.
4. Brainwashed
Though not a psychology term at all, brainwash brings up a topic that should be cleared up. When we refer to someone as being 'brainwashed' it's assumed that someone used some psychology technique to persuade someone to act, do or think a certain way. In reality, there is no formula or psychology technique that is used to brainwash someone. It's not a thing. At all. Humans are susceptible to being persuaded and tricked, but there's not a technique that does this. So please, let's stop with the conspiracies.
5. Delusional
"She's so delusional" is a quote used to talk about someone who is just out of it, who isn't aware of the circumstances or as an interesting take on reality. However, delusion is usually a consequence of various serious mental health disorders such as schizophrenia, a diagnosis that can have a great impact on one's life. Delusion is described as holding a belief that is different than reality. Yes, your friend may think he can get that even if he does not talk to her, does not mean he is exhibitning delusion. And if we believe someone is, we should not romanticise it, we should take great concern and care for those so that they may get the help they need.
