Are intrusive thoughts normal or not?
Imagine you’re lying in bed when a sack of cocaine falls from a plane, crashes through your roof, and lands next to you. You call the police, who come round and arrest you for possession.
This would be ridiculous. You are not responsible for things that fall into your house.
Now imagine you’re lying in bed when murderous, violently sexual, or discriminatory thoughts pop into your head. These are unbidden, unwanted, and in complete opposition to your values. Are you responsible for what has fallen into your mind? Do intrusive thoughts about murder make you a murderer? Are intrusive thoughts normal or not?
How common are unwanted intrusive thoughts?
How common are intrusive thoughts? Anxiety-producing intrusive thoughts are thought to occur in around 94 percent of the population. Intrusive thoughts are thoughts that enter your consciousness, often without warning or prompting, with content that is alarming, disturbing, or just flat-out weird.
If you make these thoughts public, perhaps tweeting in horror about them, you will quickly discover you are held responsible and will be punished. The Twittersphere will descend, claiming you are unfit to work and live in human society. People will learn never to speak of having such thoughts.
'Unwanted intrusive thoughts are thoughts that enter your consciousness, often without warning or prompting, with content that is alarming, disturbing, or just flat-out weird.'
So are intrusive thoughts normal or not? What if having such intrusive thoughts turns out to be normal? The human condition would become literally unspeakable. This would not only be ridiculous, but it would also have serious implications for our health.
More than 90 percent of people have common intrusive thoughts
If you ask people in Africa, Asia, Australia, Europe, North America, or South America if they are having intrusive thoughts, you will typically find that more than 90% have recently experienced some form of intrusive thoughts. These most often involve themes of doubt, such as thinking you left the cooker on or a door unlocked.
But some common intrusive thoughts will have content that goes against the person’s own values. A study published in 1978 found people reporting unwanted intrusive thoughts about acts of violence during sex, throwing a child out of a bus, and jumping in front of a train. Most people who had such thoughts could easily dismiss these unwelcome visitors. But are intrusive thoughts normal about violent acts normal?
Later research discovered how common intrusive thoughts about violence and sex were. It was found that 60% of people reported such thoughts about running a car off the road, 46% had them about hurting family members, and 26% had them about fatally pushing a stranger. Also, 6% of men and women reported having such thoughts about sex with animals or non-human objects, 19% of men and 7% of women had them about a sexual act with a child or minor, and 38% of men and 22% of women had them about forcing another adult to have sex with them.
To be clear, we are talking here about such common intrusive thoughts occurring in people who find them abhorrent. If the person does not find them repugnant, does not try to suppress or avoid them, does not try to avoid situations that trigger them, or is aroused or acts on them, then there is cause for concern. Someone who felt this way about intrusive sexual thoughts they had about children is a potential sexual offender.
Why do we experience these common intrusive thoughts?
The answer to the question of why we experience these common intrusive thoughts is unclear.
One theory is that they help problem-solving by facilitating brainstorming. Why they are often violent or sexual is also not clear.
An evolutionary psychologist has argued that “all of us house in our large brain-specific specialized psychological circuits that lead us to contemplate murder as a solution to specific adaptive problems.” However, cultural arguments can also be made, such as that patriarchy encourages hostile sexual thoughts against women.
There are limitations to research in this area. Much of it, for example, has been conducted with university students, which provides an incomplete picture. Nevertheless, it appears that having intrusive thoughts you find repugnant is common. But should people be punished for having them?
Punishing the mind for common intrusive thoughts
Legally, we have an absolute right not to be penalized for our thoughts. The primary justification for this is that thoughts alone cannot harm others
What’s more, if we criminalized every improper thought then, as was noted in the 1880s, “all mankind would-be criminals, and most of their lives would be passed in trying and punishing each other.” This is not an entirely inaccurate description of social media.
The legal protection for thoughts that are spoken is no longer absolute. Speech has the potential to create a “clear and present danger” and harm others. But disclosing an abhorrent unwanted intrusive thought, which you explicitly disavow, may be most likely to harm yourself.
Human nature and social media have combined to make disclosing intrusive thoughts a dangerous endeavor. Because social status is phenomenally important to humans, we are primed to increase our own dominance and reduce that of others. Social media provides a devastatingly effective mechanism for dominance regulation. It allows the public skewering of individuals and enables others to drive the stake home through schadenfreude.
This can be positive, bringing down those who have abused power. But it also encourages bad faith attacks in which intentional misinterpretation and simulated outrage are used to socially demote a target and socially promote the attacker.
Reality is forced underground. Difficult truths shift to places such as the intellectual dark web. This leaves the mainstream with an image of human beings that bears little resemblance to reality. This is dangerous for both individuals and society.
The dangers of unspeakable common intrusive thoughts
The idea that it is abnormal to have intrusive thoughts can itself harm people’s mental health. This is because how we think about our thinking affects our mental health. If you think you should have perfect control over what comes into your head, you are going to think poorly of yourself when an intrusive thought comes along.
This can encourage mental health problems.
If you think you are responsible for your intrusive thoughts and that they imply something about your character, if you worry about them and punish yourself, this can also have negative effects on your mental health. This can lead to more frequent and distressing thoughts, which can be symptomatic of obsessive-compulsive disorder (OCD).
Not knowing that people commonly have such thoughts, but don’t act on them, is also problematic. This could lead you to wrongly believe that having a thought about hurting someone, for example, means that you are likely to actually do it. This is called “thought-action fusion” and has also been implicated in the development of OCD.
So a public conversations, even uncomfortable conversations, about common intrusive thoughts could protect mental health. This conversation should also include whether changes to our culture might help reduce certain repugnant intrusive thoughts.
Having a false image of what people are actually like will also harm the health of society. For example, communism portrayed the need for status and private property as not being part of the human condition. It hence proposed it could be purged by education and coercion.
The horrors that resulted from this in the Soviet Union, including famine and the Gulag system of forced labor camps, remind us of the stakes here. If we cannot honestly discuss our experiences of being human without being socially immolated, we will not have prevented something monstrous, we will have created it.
But how do we create a safe space for truth? How can we encourage people to take a more charitable stance towards others trying to have difficult conversations about the human condition? Social learning theory suggests we need people to model this for us. Whether this can overcome the countervailing forces of human nature in the social media age remains to be seen.
So, in conclusion, are intrusive thoughts normal? the answer is clearly yes.
