# Associations of genetic variants for educational success with risk and time preferences vary by childhood environment

## TL;DR

This study finds that genetic factors linked to educational success influence risk and time preferences differently depending on whether someone grew up in an advantaged or disadvantaged childhood environment.

## Contribution

The study reveals that the relationship between cognitive-related genetic variation and economic preferences is contingent on childhood environmental conditions.

## Key findings

- Genetic variance related to educational success is linked to lower risk aversion and greater patience in advantaged childhood environments.
- In disadvantaged environments, the same genetic variance is associated with greater risk aversion and weaker patience.
- Childhood adversity may redirect the developmental expression of cognitive-related genetic variances.

## Abstract

Prior research shows that individuals with higher cognitive ability tend to be more patient and less risk-averse, while childhood environments also exert a strong influence on the development of these preferences. This raises the question of whether associations between cognition and economic preferences are consistent across early-life contexts. I test this using incentivized experimental (\documentclass[12pt]{minimal}

I find that genetic variance related to educational success is associated with lower risk aversion and greater patience, but only among individuals raised in more advantaged childhood environments. Among those who experienced childhood adversity, this genetic variance instead predicts greater risk aversion, and its association with patience is substantially attenuated. These patterns suggest that early adversity may canalize, constrain, or redirect the developmental expression of cognitive-relevant genetic variances in ways that are adaptive to context. Causal research is needed to ascertain if such environmentally contingent expression of genetic variances can reinforce patterns of social immobility.

Higher cognitive ability is often linked to lower risk aversion and greater patience. Using polygenic scores and experimental data, this study shows that associations between cognitive related genetic variation and economic preferences vary by childhood environment.
