Summary: A large-scale analysis of over 24,000 people in the UK reveals that childhood disadvantage has a lasting impact on how intelligence translates into social success.
While higher cognitive ability is typically associated with increased trust in others, the research finds that for those who grew up in difficult environments, this “intelligence-to-trust” pipeline is significantly suppressed. This finding suggests that early-life adversity can reinforce inequality across generations by limiting the social and economic benefits that usually accompany cognitive skills.
Key Facts
- Childhood Disadvantage and Trust: Growing up in disadvantaged environments—such as workless households, single-parent homes, or care settings—is linked to lower cognitive ability and significantly reduced trust in others during adulthood.
- The Intelligence Gap: Higher cognitive ability strongly correlates with greater trust among those from advantaged backgrounds, but that same intelligence has only about half the effect on trust for those who experienced early-life disadvantage.
- The ‘Matthew Effect’: The research highlights a pattern where individuals with early-life advantages not only develop stronger skills but also gain more social benefits from those skills throughout their lives.
- Environmental Learning: While people with higher cognitive ability generally recognize trust as a rewarded strategy in stable environments, harsher environments with instability or crime may offer fewer opportunities for intelligence to translate into social cooperation.

A new study by Professor Chris Dawson, published in Personality and Social Psychology Bulletin, finds that childhood disadvantage is linked not only to lower cognitive ability in adulthood, but also to lower levels of trust in other people.
The research suggests that intelligence does not deliver the same social advantages for everyone. Among people from more advantaged backgrounds, higher cognitive ability was strongly associated with greater trust in others. Among those who experienced childhood disadvantage, the same cognitive ability had only around half the effect.
Professor Dawson, from the University’s School of Management, said: “We often assume that intelligence leads to positive social outcomes in the same way for everyone but these findings challenge that idea.
“People who grow up in difficult environments not only develop lower cognitive skills, but also those skills appear less likely to translate into trust and the wider benefits that come with it.
“This matters, because trust helps people build relationships, succeed in organisations, and participate in society. If early disadvantage suppresses those benefits, it may reinforce inequality across generations.”
The findings are consistent with a broader ‘Matthew Effect’, where people with greater early-life advantages not only develop stronger skills, but also gain more benefit from those skills throughout life.
The study analysed data from more than 24,000 people across the UK to examine how childhood environments shape both cognitive development and social attitudes later in life.
Childhood disadvantage included factors such as living in workless households, growing up in single parent households or care settings, and parents with low educational qualifications, or lower occupational status. Those who experienced two or more forms of disadvantage were significantly less likely to trust others as adults.
Previous research consistently shows that people with higher cognitive ability tend to be more trusting and cooperative. One explanation is that they are better able to recognise that trust is likely to pay off socially and economically, and more able to override instinctive distrust or fear in uncertain situations.
“In stable and supportive environments, people with higher cognitive ability may be more likely to learn that trust is a socially rewarded and adaptive strategy – that cooperating with others often pays off,” said Professor Dawson.
“But in harsher environments, where individuals are more likely to experience instability, crime, or unreliable institutions, there may be fewer opportunities to learn that trust is beneficial or rewarded.
“In those environments, intelligence may simply have fewer opportunities to translate into trust. Early adversity may also leave lasting effects of stress and anxiety that limit how cognitive abilities are expressed in social life.”
Research has shown trust to be one of the key foundations of successful societies, economic prosperity, lower crime, and social cooperation.
The study also found evidence of similar patterns internationally. In high-income countries, cognitive ability was strongly associated with trust, while in lower-income countries the relationship was substantially weaker.
The new findings suggest childhood conditions may play a much bigger role in shaping these outcomes than previously understood.
The study argues that tackling inequality should not focus only on educational attainment or income, but also on the emotional and social environments children grow up in.
“If we want to improve life chances, we need to think beyond academic skills. Stable, secure and supportive childhood environments may be just as important in helping people realise their potential,” said Professor Dawson.
Key Questions Answered:
A: In unstable or harsh environments, intelligence may be used as a tool for survival and caution rather than cooperation. If early life taught you that institutions or people are unreliable, your brain may override the logical “payoff” of trust to prioritize self-protection.
A: The researchers looked at several factors: living in workless or single-parent households, being in a care setting, or having parents with low educational or occupational status. Experiencing two or more of these made a person significantly less likely to trust others as an adult.
A: The pattern is global. In high-income countries, intelligence and trust are strongly linked; however, in lower-income countries where environments may be harsher, that relationship is substantially weaker.

“What Childhood Leaves Behind: Cognitive Ability and Trust in Adulthood” by Chris Dawson. Personality and Social Psychology Bulletin

Abstract
What Childhood Leaves Behind: Cognitive Ability and Trust in Adulthood
This article challenges the idea that cognitive ability uniformly predicts prosocial traits. Using data from a large, nationally representative U.K. sample (N = 24,140), we test a moderated mediation model in which childhood disadvantage is associated with generalized trust both directly and indirectly via cognitive ability, while also moderating the association between cognitive ability and trust.
We find that childhood disadvantage is associated with lower cognitive ability—measured across memory, verbal fluency, fluid reasoning, and numerical reasoning—and with lower generalized trust in adulthood.
We also find that cognitive ability is positively associated with generalized trust; however, this relationship is significantly attenuated among those who experienced childhood disadvantage.
These results persist after adjusting for current socioeconomic factors. The pattern whereby early-life disadvantaged environments are associated with differences in cognitive development and with constrained social returns to cognitive ability is likely to reinforce social immobility.
