IQ and Happiness: The Link Between Intelligence and Well-Being

The relationship between IQ and happiness suggests that people with higher IQ scores are predisposed to be happier. Intelligence levels influence problem-solving abilities and career opportunities, contributing to overall life satisfaction.

Therefore, boosting your brain power can enhance your happiness and vice versa. Mind-challenging activities, such as mindfulness, can improve your well-being and resilience. Likewise, maintaining a positive outlook on life can support cognitive development, creating a cycle where IQ and happiness reinforce each other.

In the following lines, we’ll take a closer look at the IQ and happiness correlation, explaining how intelligence impacts life satisfaction and offering tips on increasing happiness levels.

Let’s begin!

Key Takeaways

• There’s a correlation between IQ and happiness, but other factors, including socio-economic and clinical, are more closely linked to life satisfaction.
• There are nine types of intelligence, including logical-mathematical, verbal-linguistic, intrapersonal, and interpersonal intelligence.
• Social sciences define two types of happiness—subjective (self-reported) and objective (externally measured).
• Emotional intelligence has a greater impact on happiness and life satisfaction than IQ.
• Increasing happiness levels is possible through building stronger relationships, practicing mindfulness and gratitude, exercising, and spending time outdoors.

What is IQ?

IQ, or intelligence quotient, is a score derived from a standardized IQ test devised to measure cognitive development. It includes abstract thinking, attention span, logical reasoning, memory, and problem-solving abilities.

The standardized IQ test isn’t a single intelligence assessment tool but rather a term encompassing several widely recognized tests designed to evaluate cognitive abilities. These include the Stanford-Binet Intelligence Scale, Raven’s Progressive Matrices, and the Differential Ability Scales, to name a few.

These tests apply advanced psychometric techniques to measure cognitive development by comparing the test taker’s performance to their peers’ results. Their score is expressed in percentiles—for instance, a person who performs better than 95% of their peer group belongs to the 95th percentile.

The percentiles are then converted to an equivalent score on the Stanford-Binet scale, which ranges from 40 to 160. The person in the 95th percentile has an above-average IQ score of 125.

9 Different Types of Intelligence

According to Howard Gardner’s multiple intelligences theory, there are nine types of intelligence, as follows:

• Visual-spatial intelligence is the ability to perceive and interpret information from the physical realm and visualize 2D images and 3D objects without external prompts.
• Logical-mathematical intelligence includes problem-solving abilities, recognizing patterns, processing numbers, and understanding abstract concepts.
• Verbal-linguistic intelligence is the ability to understand linguistic rules in native and foreign languages and express your thoughts well verbally and in writing.
• Bodily-kinesthetic intelligence is the ability to use your body for both physical tasks and expressive movement, master physical skills, and body language, and skillfully manipulate objects.
• Musical intelligence is the ability to express yourself through music and lyrics and understand musical elements such as melody, pitch, and tone.
• Intrapersonal intelligence entails self-awareness, emotional regulation, setting personal goals, and prioritizing your needs and emotions regardless of others’ expectations.
• Interpersonal intelligence includes communication skills and the ability to understand and empathize with others.
• Naturalistic intelligence is the ability to recognize and classify natural elements through observation and connecting with nature.
• Existential intelligence, never officially recognized, includes curiosity about humanity and existence, big-picture thinking, developed intuition, and a philosophical mindset.

What is Happiness and Life Satisfaction?

Happiness and life satisfaction are often used interchangeably. However, while they’re related, they don’t mean the exact same thing. In the broadest sense, happiness is an emotional state defined by feelings of contentment and joy.

Meanwhile, life satisfaction is a component of happiness and refers to a positive attitude toward your life.

Since happiness is a broad term, social sciences typically distinguish between subjective well-being and objective happiness. The difference lies in the ways happiness is experienced and measured.

Subjective well-being is a person’s internal feeling of happiness. In addition to overall life satisfaction, it includes positive emotions, thoughts, moods, and individual perceptions. It’s influenced by personality traits, mental state, and life experiences, which all vary from one person to another.

As such, subjective well-being is self-reported, meaning it’s based on how content someone feels with their emotional state, achievements, and relationships. For example, a person can have a low-income job yet feel happy because of their positive outlook on life or emotional fulfillment.

On the other hand, objective happiness involves externally measurable factors that can contribute to an individual’s well-being. These include health, social status, income, and wealth. However, just because a person meets all the external conditions for happiness doesn’t mean they’re subjectively (internally) happy.

Notably, Kahneman’s definition of objective happiness is closer to what’s generally considered subjective well-being. Namely, he suggests objectively measuring subjective experiences as they happen rather than retrospectively, which is how people usually evaluate how happy they feel about their lives.

Is There a Correlation Between IQ and Happiness?

The relationship between IQ and happiness has piqued researchers’ interest, leading to a range of studies exploring the subject. The findings are complex, indicating that while there is an association, intelligence is just one of the factors influencing happiness.

Some research shows IQ and life satisfaction have a positive correlation. They suggest that higher intelligence can help people deal with difficult situations better so they’re happier overall.

According to a study by Veenhoven and Choi, higher IQ scores come with better adaptability and problem-solving skills. As a result, you can achieve personal goals more easily and feel more satisfied in life.

Similarly, a paper by Zagorsky suggests that people with higher intelligence have more access to education and career opportunities. This can mean financial stability, which is one of the objective happiness factors.

Additionally, a study by Ali et al. finds that socio-economic and clinical factors mediate the relationship between IQ and happiness. Namely, individuals with higher IQ scores have better employment opportunities and mental health awareness, so they’re more satisfied in life.

However, there are also some downsides to having a high IQ in terms of happiness. According to a paper by Karpinski et al., highly intelligent people can be prone to perfectionism and social isolation, which can negatively affect their life satisfaction.

They also tend to be more aware of existential concerns and global issues, experiencing overall dissatisfaction and anxiety, as noted by Chamorro-Premuzic and Furnham.

The Role of Emotional Intelligence in Happiness and Satisfaction With Life

The role of emotional intelligence (EQ) is greater than that of IQ when it comes to happiness and satisfaction in life.

Research by Salovey and Mayer emphasizes that individuals with higher emotional intelligence are more likely to report higher happiness levels. The reason is that EQ impacts your ability to manage emotions, have meaningful relationships, and handle social situations and life challenges.

Let’s break down the effects of emotional intelligence on happiness:

• Improves emotional regulation: Emotional intelligence helps you recognize and handle emotions in healthy ways. People with high EQ respond more calmly to situations, reducing emotional distress and maintaining emotional stability.
• Strengthens relationships: Emotional intelligence involves empathy, the ability to understand and share others’ feelings. Therefore, it helps build positive social interactions, contributing to overall quality of life.
• Increases self-awareness: As a core component of emotional intelligence, self-awareness allows you to understand what makes you happy or triggers negative emotions. This can lead to healthier life choices that align with your values and result in long-term happiness.
• Builds resilience: Emotionally intelligent people are better at maintaining optimism in the face of challenges. As such, they’re more likely to lead happier lives, not allowing stressful situations to have a lasting impact on their well-being.
• Enhances empathy: Empathy fosters positive emotions in others as well as yourself. In the long run, acts of kindness lead to greater life satisfaction.
• Reduces negative emotions: People with high emotional intelligence are better at managing negative emotions. They’re less likely to dwell on sadness or anger and successfully maintain a positive mindset.
• Increases social support: People with higher emotional intelligence have better communication skills. For this reason, they have solid social networks providing emotional support during difficult times and opportunities for joy during good times.

How to Increase Your Happiness Level Beyond Your IQ Score

There are several ways to increase your happiness level beyond your IQ score. They include building stronger relationships, practicing mindfulness and gratitude, exercising, and spending time outdoors.

Let’s explore them in detail:

#1. Build Strong Relationships

Building strong relationships is one of the best predictors of happiness, no matter your IQ score. No man is an island—we all need emotional support, companionship, and a sense of belonging. Sharing both your highs and lows with others creates a social buffer against stress.

Having a circle of close people to share your wins and turn to during struggles makes for resilience. Additionally, giving and receiving care within relationships builds empathy and a sense of purpose, both cornerstones of long-term life satisfaction.

The quality of these relationships—with friends, family members, or romantic partners—is key. Authentic connections bring joy and give you a safe space to talk about your thoughts and feelings.

#2. Practice Mindfulness and Gratitude

In their own unique ways, both mindfulness and gratitude promote awareness and appreciation for the present moment and little blessings in life.

Through mindfulness, you can learn how to handle stress and lessen its impact by shifting focus away from worries about the past or future. By focusing on the present, you can balance your perspective, making finding joy in simple everyday experiences easier.

Gratitude goes hand in hand with mindfulness by bringing positive aspects of life into focus. Practice it by actively recognizing and appreciating the good things you have, such as good health, meaningful relationships, and even small pleasures. This will help you shift attention from what you may be lacking to what’s already fulfilling.

#3. Exercise

Exercise positively impacts both physical and mental well-being and is thus a powerful tool for enhancing life quality, including happiness.

Physical activity releases endorphins, also known as “feel-good” hormones, which naturally boost your mood and lower stress and anxiety levels. This biochemical effect, or “runner’s high,” can create a lasting sense of contentment and relaxation post-workout.

Regular exercise also improves energy levels, sleep quality, and physical health. Additionally, a workout routine contributes to feelings of accomplishment and discipline, boosting confidence.

Group activities, such as team sports, also have an element of social interaction, an important factor in overall life satisfaction, as previously mentioned.

#4. Spend Time Outdoors

Spending time outdoors creates a sense of connection with nature, which has many mental health benefits. Greenery and water provide a calming atmosphere by lowering cortisol levels, the body’s primary stress hormone. In fact, being in nature is a unique form of meditation, which we already know is a powerful way of increasing happiness.

Exposure to sunlight also plays an important role in enhancing mood by boosting serotonin production, a key neurotransmitter linked to feelings of well-being. It helps improve sleep quality and energy levels, similar to exercise.

In fact, you can combine spending time outdoors and exercise by engaging in activities like hiking, walking, or swimming. Still, even sitting in a green space can have positive effects on your overall well-being and happiness.

Final Thoughts

IQ and happiness have a positive correlation, although the influence of intelligence on life satisfaction is mostly indirect. Namely, people with higher IQ scores typically have better problem-solving skills, education and employment opportunities, and higher mental health awareness.

Still, higher IQ levels can also have a negative impact on life satisfaction. Highly intelligent individuals are prone to self-isolation, perfectionism, and pondering existential concerns, all of which can lead to anxiety and overall dissatisfaction.

That said, emotional intelligence plays an important role in fostering happiness. It improves emotional regulation, relationship quality, self-awareness, and resilience, contributing to overall well-being.
