Logical reasoning may improve as we learn to process principles intuitively

In short: Researchers comparing 7th and 12th grade students found that as people age, their initial, instinctive responses to logic problems become more accurate. By testing students on syllogisms and base-rate problems, the study observed that older students were more likely to reach the correct conclusion immediately, suggesting that logical accuracy improves as reasoning becomes automated.

This study supports the hypothesis that logical reasoning develops through a process of automatization, where slow, deliberate thought transitions into fast, intuitive processing. The researchers used a two-response paradigm to compare the first instinctive answers of younger and older students against their subsequent deliberate corrections. While these findings suggest that developmental gains in reasoning are driven by more accurate intuitions, the study's focus on specific grade levels may not represent the entire lifespan of cognitive development.

Why it matters: Our ability to reason accurately may depend on our brains learning to process logic instinctively rather than through slow deliberation.
