8. “Multiple personalities” is just for movies now

Multiple personality disorder has not been considered a legit psychiatric diagnosis since 1994, but it’s an idea that persists in pop culture. The closest thing is what’s known as dissociative identity disorder , characterized by a sense of detachment from your own emotions.

The idea that a person can “split” their personalities, with each being unaware of the others, was popularized by the 1973 book (and later movie) Sybil . The book was supposedly based on a true story, but the woman it was based on has said that the multiple personalities were not real .

It turns out that people can be persuaded, and they can be pressured or tortured into saying things they don’t believe. You don’t need a sinister psychological phenomenon to explain that.

I’m sorry (or perhaps pleased?) to report that brainwashing is not, in fact, a thing. The term was used to describe American soldiers in the Korean war who appeared to side with thei...

2. Antidepressants aren’t just for depression

Antidepressants are real, and they are often useful in the treatment of depression. But as the authors of the psychological terms review point out, the drugs we call “antidepressants” are at least as good at treating other things besides depression.

These classes of drugs, like tr...

. Hypnotic trances aren’t real

Hypnosis is real, in the sense that one person can make another person (or themselves) more open to suggestion. But that doesn’t mean that the person being hypnotized is in a “trance state” that is different than normal consciousness. Being hypnotized

Certain functions of the brain have been described as hard-wired, meaning that they are permanent features of how our brains work. But this isn’t true unless you’re talking about very basic functions, like the circuits that keep us breathing. Just about everything our brains can do is

Psychology-related words and phrases tend to creep into our everyday vocabularies. Unfortunately, many of them have been twisted in our minds, and we now use them to refer to the wrong thing—or, in some cases, science has moved on and we’re talking about something woefully outdated. Here are some...

. We’re all using “steep learning curve” wrong

People often refer to skills as having a learning curve. The idea is that you learn more about a subject as you spend more time working on it, and that the experience can be described in terms of a graph with time along the bottom, and y...

But we misuse the term when we describe a difficult subject as having a “steep learning curve.” If the line on the graph immediately shoots up, we might imagine ourselves climbing a mountain to reach proficiency.

3. Brain areas don’t “light up”

Studies on brain function are often described by saying that an area of the brain “lights up” when doing a task or experiencing some particular situation. But that’s a description based on how brain scans look when they’re published, not what actually happens in the brain.

4. Your personality traits are hard-wired

The description that certain abilities or personality traits are “hard-wired” is borrowed from the computer world.

6. Lie detectors don’t work

“Lie detectors” do no such thing. They cannot tell you whether a person is lying, only whether they are nervous. And if you think that anyone might be nervous while hooked up to a machine and peppered with personal questions, well, then you get why so-called lie detectors are useless.

7. Oxytocin isn’t a “love molecule”

Oxytocin has often been described as a “love molecule” because it’s been associated with social bonding. When you look at your adorable child or puppy, oxytocin is probably sending signals in your brain and body to coordinate that “awwww” reaction.
