Is Television an Effective Tool in Building the Minds of Children?

Is the Idiot Box Making You Dumber?

Television has been a part of children’s lives for generations. It can educate, entertain and introduce children to places, people and ideas that they might otherwise never encounter. But there is another side to the screen that is worth examining: does television build a child’s mind, or does it sometimes do the imagining for them?

When a child listens to a story, something interesting happens inside the mind. If the story describes a forest, a castle or a strange creature, the child has to create those things mentally. The storyteller provides the words, but the child supplies the images. The same thing happens when a child reads a book: the author provides the description, while the child’s imagination constructs much of the world.

That is one of the beautiful things about reading. A character in a book does not necessarily arrive with a complete face, voice, expression and manner of movement. The child has to construct those details. Two children can read exactly the same story and imagine completely different characters. The words are the same; the mental pictures are personal.

Television changes that equation. The character already has a face. The house has already been designed. The forest already looks a certain way. The voice, music, colours, movement and camera angles are supplied by somebody else. The child can still think about the story, of course, but much of the visual construction has already been done.

1. The Power of a Book — and a Story

Reading a book and listening to a story may look different, but they ask something similar from a child’s mind. In both cases, the child receives words rather than a complete visual world. Characters have to be imagined, surroundings have to be constructed and events have to be mentally played out.

When a book says that a character entered an old house, the author does not have to describe every wall, window, chair and shadow. The child’s mind fills in those details. One child may imagine a dark, frightening house; another may imagine an old but beautiful one. Neither mental picture is necessarily wrong. The imagination has room to participate.

The same thing happens when a parent tells a child a fairy tale. A dragon described as enormous and frightening does not have one fixed appearance inside every child’s head. Each child creates a dragon from their own imagination and experience. The story provides the framework, but the child’s mind completes the picture.

This is one reason reading can be such an active mental experience. Research on mental simulation in reading has found that readers use perceptual and motor experiences to construct richer representations of what they are reading. In one intervention study involving primary-school children, training that encouraged mental simulation was associated with improved reading comprehension, particularly among third-graders, as well as increased reading motivation. Read the study.

Television works differently. It does not eliminate thinking, but it supplies much more of the sensory experience in advance. The child does not have to decide what the character looks like or what the castle might look like because those decisions have already been made.

A book gives the child the ingredients to create a world. Television gives the child a world already created.

2. Is the Idiot Box Really Making Us Dumber?

Television has often been called the “idiot box.” It is a deliberately insulting expression, suggesting that the screen can turn the viewer into a passive recipient rather than an active participant. But perhaps the phrase is more interesting if we stop interpreting “dumber” simply as less intelligent.

The more useful question is whether some forms of television viewing give the developing mind less work to do. A child who spends an afternoon inventing a game, building something from blocks or listening to a story has to make decisions. There are gaps to fill, problems to solve and possibilities to imagine. A screen, particularly when consumed passively for long periods, can remove many of those gaps by continuously supplying the next image, sound and event.

This does not mean television automatically makes children stupid. In fact, the scientific evidence is considerably more complicated. A 2017 systematic review examined 76 studies on television exposure and children’s cognition and behaviour. It found that outcomes depended on factors including the content being watched, the child’s characteristics and the viewing context. Educational television could even support learning, particularly among preschool children. Read the systematic review.

So the old phrase “idiot box” should not be treated as a scientific conclusion. It is better understood as a provocative question: what kind of mental activity is a child doing while watching television—and what kind of activity might the television be replacing?

3. What Does the Research Say?

There is some scientific evidence that makes this question worth asking. A 2024 systematic review examined 15 experimental studies involving 1,855 children aged 2–7 and investigated how features such as television pacing and fantasy content affected attention and executive functions. The results were mixed, and the researchers stressed that the effects depend on the content, the child and the surrounding environment. However, the review identified patterns suggesting that certain television characteristics can influence aspects of attention and executive function. Read the 2024 review.

That is a very different claim from saying that television makes children unintelligent. Science does not give us such a simple answer. The more defensible conclusion is that different kinds of media demand different kinds of participation from the mind, and those differences may matter during childhood.

A fast-moving, highly stimulating cartoon is not the same as a carefully designed educational programme. Watching television with a parent and discussing what is happening is not the same as sitting alone for hours consuming an endless stream of content. A child reading a book is doing something different again.

The important question is therefore not simply screen versus no screen. It is what the screen contains, how it is used and what it displaces.

4. Then Why Read Fairy Tales?

There is a famous quotation attributed to Albert Einstein:

“If you want your children to be intelligent, read them fairy tales.”

Whether the quotation can be firmly traced to Einstein or not, the idea behind it fits the question we are exploring. A fairy tale does not merely entertain a child. It gives the imagination something to work with.

When a child hears about a magical kingdom, a talking animal or a mysterious forest, the child’s mind participates in creating that world. The story provides the raw material, but the imagination supplies many of the details.

Perhaps that is what makes fairy tales valuable. They do not give the child everything. They leave something for the child to create.

5. The Problem Is Not Television

It would be easy to turn this into another argument against television. That would miss the more interesting point. Television can be wonderful. A good documentary can make a child curious about space, animals or history. An educational programme can explain something that would otherwise be difficult to understand. A well-made story can provoke questions, emotions and discussion.

The problem begins when entertainment becomes almost entirely passive and starts replacing activities that require the child to create something independently. Reading, drawing, building, playing, inventing games, telling stories and exploring the physical world all require different kinds of participation.

A child also needs time in which nothing is being supplied. That may sound strange in a world obsessed with keeping children entertained, but boredom can create an opportunity. A cardboard box can become a spaceship. A stick can become a sword. A bedsheet can become a tent. When the world does not immediately provide entertainment, the child may begin creating it.

6. From the Idiot Box to the Intelligent Machine

When this article was originally written in 2017, television was still the obvious screen to question. The situation has changed dramatically since then. Children now move between televisions, smartphones, tablets, YouTube, games and algorithmically selected streams of content. The screen is no longer something that sits in one corner of the house waiting to be switched on. It can follow a child everywhere.

And technology has become increasingly good at providing ready-made experiences. Television provided ready-made images. The internet provided ready-made information. Social media provides ready-made streams of opinions, reactions and entertainment. And now artificial intelligence can increasingly provide ready-made answers, images, stories and ideas.

This does not make AI the new idiot box. But it makes the old question more important.

7. Who Is Doing the Thinking?

Technology itself is not the enemy. A television can teach. A computer can create. A smartphone can open an enormous world of knowledge. AI can help a child explore ideas that might otherwise be difficult to understand.

The important distinction is between using a tool to extend thinking and using a tool instead of thinking. A calculator does not make a mathematician stupid because the mathematician still needs to understand the problem. A book does not make the reader passive simply because someone else wrote the words. Likewise, AI does not necessarily reduce thinking if it is used as a tool for questioning, exploring and challenging ideas.

The danger comes when the technology becomes so convenient that we stop doing the mental work ourselves. For children, this distinction may matter even more. A developing mind needs opportunities to struggle with questions, invent possibilities, make mistakes, imagine things that do not exist and discover solutions without being handed a finished answer every time.

8. So, Is Television Making Children Dumber?

Not necessarily. The question is too simple for something as complicated as a child’s development. Television is a tool, and its effect depends on what is being watched, how it is being watched, how much time it occupies and what the child is doing when the screen is off.

But there is a question worth asking every parent—and perhaps every adult: How much of what we experience is something we have created ourselves, and how much has already been created for us?

Television once gave us ready-made pictures. The internet gave us ready-made information. Social media gives us ready-made opinions and endless streams of content. AI is beginning to give us ready-made answers, images, stories and ideas.

The challenge is therefore bigger than simply deciding whether television is good or bad. We need to leave enough room for the child to imagine something that the machine did not imagine first.

Because intelligence is not only the ability to absorb information. It is also the ability to create something from what isn’t there yet.
