TL;DR
A recent study finds that highly intelligent individuals are more likely to abandon old habits for better ideas, especially when the new solutions are superior. Openness to experience also plays a role in adopting similar or worse solutions. This insight enhances understanding of social learning and innovation dynamics.
Research published in 2023 confirms that individuals with higher intelligence are more likely to abandon old habits in favor of better solutions when they become available, highlighting a key factor in social learning and adaptation.
The study, conducted by Tiarn Burtenshaw and colleagues, involved 201 university students from Australia and 369 participants from the UK. It found that higher intelligence significantly increased the likelihood of switching to novel, superior solutions in problem-solving tasks, such as the Padlock and Maze tasks. Participants with greater openness to experience were more prone to adopt solutions similar or inferior to existing ones, indicating personality influences social learning behaviors.
The research also revealed that increased familiarity with a solution reduced the tendency to switch, a phenomenon termed ‘maintenance bias.’ Longer training on a solution decreased social learning, emphasizing the role of experience in decision-making. The findings suggest that cognitive ability and personality traits shape how people adopt new behaviors, which has implications for understanding innovation and behavioral change.
Implications for Understanding Innovation and Behavior Change
The findings clarify why some individuals are more adaptable and receptive to new ideas, which is critical for innovation, education, and social progress. Recognizing that higher intelligence fosters openness to adopting superior solutions can inform strategies for promoting behavioral change and learning in various settings.
Understanding these traits can help design interventions that encourage beneficial habits and facilitate social evolution, especially in environments demanding rapid adaptation.

Social learning—the process of acquiring behaviors through observation—has been central to human evolution, enabling the spread of knowledge and norms. Prior research indicated that traits like openness influence learning behaviors, but recent studies have focused on how intelligence affects the likelihood of adopting better solutions. The current research builds on this by experimentally examining how individual differences in intelligence and personality influence decision-making in problem-solving tasks, providing nuanced insights into behavioral adaptation.
“Our findings demonstrate the importance of individual differences in intelligence and personality, alongside experiential factors, to human social learning.”

Unclear Impact in Real-World Contexts
It remains uncertain how these laboratory findings translate to real-world scenarios where solutions have practical consequences. The study’s tasks were abstract and short-term, so further research is needed to confirm if higher intelligence similarly promotes innovation and habit change in complex, real-life environments.

Key Questions
Does higher intelligence always lead to better decision-making?
Not necessarily; while higher intelligence correlates with a greater likelihood of adopting superior solutions, other factors like personality and context also play significant roles.
Yes, traits like openness to experience are associated with a tendency to explore and adopt new or similar solutions, even if they are not better.
Are these findings applicable outside laboratory settings?
The applicability to real-world situations remains uncertain, as the study was based on short, abstract tasks. Further research is needed to confirm relevance in practical contexts.
How might this research influence educational or organizational strategies?
Understanding that higher intelligence and openness facilitate adopting better ideas could inform approaches to encourage innovation and adaptive behaviors in various settings.
