7 Phrases That May Signal Lower IQ Scores

We all occasionally say something without thinking. Researchers become interested, however, when particular expressions recur so regularly that they begin to reveal a person's habitual way of thinking. When used consistently, such phrases may indicate reluctance towards effort, curiosity and self-examination – qualities often associated with lower results in standard intelligence tests.

Language as a window into thinking

Psychologists have long maintained that our language reflects how we make sense of the world. This does not mean that a single remark can “diagnose” anybody's IQ – life circumstances, education and personality are much too complicated for that. Even so, repeated speech patterns can offer clues about how a person handles information, difficulty and subtlety.

Phrases that shut down effort, curiosity or responsibility often point to limited cognitive flexibility rather than raw stupidity.

The seven expressions below are not intended as a tool for labelling people. Instead, they are warning signs which, considered alongside behaviour and decisions, may suggest a reduced willingness to expend mental effort and develop.

1) “I’m just not a book person”

A person who proudly claims they “hate books” is not necessarily just picking Netflix instead of novels. In some cases, the remark reflects a broader avoidance of prolonged mental effort. Reading – whether novels, history or in-depth journalism – requires concentration, imagination and critical thought.

Educational research shows that intensive instruction can substantially improve reading ability, even for children with lower IQ scores. This indicates that motivation and perseverance, rather than an unalterable ceiling, are often the key issue. When an adult rejects reading completely, they may be turning away from one of the most affordable and available ways to develop their mind.

“I’m not a book person” often really means “I don’t want to engage with anything that stretches me for more than five minutes.”

Of course, reading very little does not automatically mean that someone lacks intelligence. Dyslexia, inadequate schooling and plain fatigue may all be factors. The concern arises when disdain for reading is displayed as though it were a point of pride.

2) “I can’t be bothered”

This expression often appears when an opportunity to learn presents itself: a training course, documentary or challenging workplace assignment. Constantly saying “I can’t be bothered” or “I don’t have the patience” can reveal a more fundamental unwillingness to devote mental energy.

Research into educational achievement, including work involving pupils with learning difficulties, suggests that motivation, self-control and effort are as strong a predictor of success as measured intelligence. When somebody habitually dismisses unfamiliar challenges as “too boring” or “too much hassle”, they are effectively choosing not to pursue that development.

• Short term: reduced knowledge and fewer skills
• Medium term: lost promotions and narrower career opportunities
• Long term: feeling “stuck” while other people move forward

Everyone has nights when the sofa is more appealing than self-improvement. What matters is the repeated pattern: when “I can’t be bothered” is the automatic response to every form of mental effort, it often signals an intellectual appetite that has stopped progressing.

3) “That’s just how it is”

Said on one occasion, “that’s just how it is” may simply be a quick way of speaking. When used continually, though, it turns into a device for ending conversations. It closes off questions, uncertainty and opposing arguments. Psychologically, it can suggest low openness to experience – a quality connected with less effective creative and analytical thought.

Inquisitive people ask “why?”. They test assumptions, weigh up different explanations and revise their position when evidence changes. A person who repeatedly relies on “that’s just how it is” may be unsettled by that process, or may simply have little experience of it.

When a phrase ends every debate before it begins, it often hides a fear of not having the answers.

This verbal full stop can reveal not only what a person believes, but also how far they are prepared to think things through.

4) “I hate change”

Being uncomfortable with change is normal. Rejecting all change as a matter of principle is different. Major studies have found that people with higher IQ scores generally adjust more readily to unfamiliar rules, tasks and settings. In that respect, flexibility forms part of intelligence.

Someone who says “I hate change” whenever there is a new workplace system, phone update or family alteration may be expressing more than a liking for routine. It may indicate:

Phrase	Possible mindset behind it
“I hate change at work.”	Difficulty learning unfamiliar procedures or tools
“I hate when plans change.”	Trouble coping with uncertainty or responding spontaneously
“Things were better before.”	Romanticising the past and resisting new information

There are exceptions, again. Anxiety, previous trauma and unstable surroundings can make change truly frightening. The important question is whether the person makes any attempt to adapt, or instead closes themselves off to all new input.

5) “I’m always right”

Those who maintain that they are “always right” frequently mistake confidence for being incapable of error. Psychologically, the phrase can indicate poor critical thinking and insecure self-esteem. Acknowledging a mistake takes mental work: you must revisit your reasoning and alter your beliefs.

Studies of personality and intelligence indicate that people who are more open and self-reflective often do better at complex problem-solving. They view being wrong as useful feedback rather than an embarrassment. Conversely, a person firmly attached to “I’m always right” blocks the principal route through which intelligence develops: learning from errors.

The smartest people in the room tend to ask the most questions, not shout the loudest certainties.

The expression can also harm relationships. It signals that conversation has no purpose, thereby cutting off the useful facts and viewpoints that might expose blind spots.

6) “I don’t need any help”

Independence in itself is not the problem. The difficulty begins when “I don’t need help” becomes an inflexible principle, despite someone plainly finding things hard. Declining support may conceal low emotional intelligence – an inability to recognise one's own emotions and limitations.

Research into students seeking help identifies a clear trend: those with greater emotional awareness are more inclined to request support at the appropriate moment, and they usually achieve more. They regard help as a useful resource rather than a danger to their ego.

By comparison, somebody who sees accepting help as a weakness often:

• Makes the same errors repeatedly instead of learning more quickly
• Feels overwhelmed in private while acting as though everything is fine
• Loses opportunities to draw on other people's expertise

In the longer term, this approach can reduce both wellbeing and performance, regardless of a person's raw IQ.

7) “It’s all their fault”

Blaming others offers a powerful shortcut. Declaring “it’s entirely their fault” removes any need to examine yourself. Yet self-reflection is a central element of both emotional and general intelligence.

Psychologists studying emotional competence define self-awareness as noticing your own part in a situation. Those who regularly place blame outside themselves rarely undertake that examination. They are stuck in traffic because “everyone else is an idiot”, lose work because “every boss is toxic”, or fail exams because “teachers are out to get me”.

When everything is always someone else’s fault, nothing can change – including your thinking.

This attitude prevents people from learning through failure. It also undermines trust: friends and colleagues soon realise that any issue involving this person will ultimately be blamed on them.

How much can phrases really tell us?

None of these statements demonstrates that a person has a low IQ. Language is untidy, and people speak from stress, tiredness, habit or humour. A very intelligent person may mutter “I can’t be bothered” after an exhausting week while remaining highly curious at other times.

Psychologists focus instead on context and frequency. If several of these phrases occur repeatedly, particularly when learning or adapting is possible, they begin to appear less like casual comments and more like an established mindset.

Seeing the mindset beneath the words

Readers considering their own language may find it helpful to try a brief mental exercise. Picture two colleagues who are offered the same demanding project at work:

Person A says, “I hate change, I can’t be bothered with new systems, and if this fails it’ll be the manager’s fault.” Person B says, “I’m not sure I’m ready, but I’ll read up, ask for help where needed, and see what I can learn.”

The distinction is about more than optimism. Person B expresses qualities that research consistently associates with stronger cognitive functioning: curiosity, adaptability, readiness to seek support and a degree of comfort with being wrong.

Shifting away from limiting phrases

Substituting more constructive alternatives for these seven phrases can gently move thinking in a healthier direction. For instance:

• Replace “I’m not a book person” with “I struggle with long texts, but I’ll try shorter pieces or audiobooks.”
• Replace “I can’t be bothered” with “I’m tired now; I’ll schedule an hour for this tomorrow.”
• Replace “I’m always right” with “Here’s how I see it – what am I missing?”

Small changes in language encourage the mind to remain open, make an effort and accept shared responsibility. In time, that outlook contributes far more to real-world intelligence than any figure on an IQ test.
