Singapore — Intelligence is often measured through IQ tests, yet experts highlight that IQ is also closely linked to social skill development. Research cited from the Journal of Clinical Child Psychology notes that a lower IQ can slow down social growth, which is often reflected in the way individuals speak and respond in daily life.
The study suggests that specific phrases may reveal limitations in thought processes. Without realizing it, these seemingly simple statements can hold back both personal and professional growth.
- “I don’t know what I want”
Unlike people with higher IQ who tend to be more self-aware and reflective, those with lower IQ often show difficulty in identifying personal goals or needs. This lack of internal reflection makes it harder to set objectives and achieve them. - “It’s impossible for me to achieve that”
A fixed mindset is a common trait in individuals with lower IQ. Statements such as “I can’t do it” or “It’s impossible” reveal a tendency to give up before trying, preventing long-term aspirations from becoming reality. - “I’m not wrong”
Defensiveness and refusal to admit mistakes are also indicators. Instead of learning from errors, people with lower IQ may deny responsibility, which hinders improvement and relationship building. - “What’s the right answer?”
This phrase suggests a focus on outcomes rather than the learning process. It often reflects a lack of curiosity, open-mindedness, and comfort with exploration—qualities essential for growth. - “I don’t know and I don’t care”
When faced with uncertainty, people with higher IQ typically seek deeper understanding. In contrast, those with lower IQ may respond with indifference, often rooted in insecurity, which prevents meaningful engagement and problem-solving.
Experts emphasize that language is more than just communication; it reflects mindset and shapes growth. Being mindful of these patterns can help individuals reframe their approach, encouraging curiosity, accountability, and resilience.
