#Bilingualism

A newly published analysis in The Economist revisits the decades-long debate on whether being bilingual actually benefits the brain, challenging long-held assumptions while highlighting persistent scientific uncertainty. With Thailand’s education system increasingly promoting English and Mandarin alongside Thai, the study’s findings carry particular weight for Thai families, educators, and policymakers contemplating the cognitive worth of learning an additional language.

For years, researchers have claimed that speaking two or more languages confers a host of cognitive advantages beyond mere linguistic prowess. In addition to opening doors to different cultural and professional opportunities, multilingualism has frequently been linked to improvements in “executive function”—an umbrella term covering skills like ignoring distractions, planning complex tasks, and adjusting one’s thinking as circumstances change. Widespread media coverage and popular science books have further fuelled the belief that bilingualism may even delay dementia, with some research suggesting bilinguals can experience the onset of dementia as much as four years later than monolinguals (The Economist).

A new analysis in The Economist revisits the long-standing question of whether bilingualism truly benefits the brain, and it cautions that the science remains uncertain. As Thailand expands English and Mandarin programmes alongside Thai, families, educators, and policymakers are paying close attention to what language learning actually delivers for cognitive health and learning outcomes.

For years, researchers have linked multilingualism to advantages beyond language—especially in executive function, which includes staying focused, planning tasks, and adapting to new rules. Media attention and popular science have bolstered the belief that bilingualism could delay dementia, with some studies suggesting bilinguals experience dementia onset several years later than monolingual peers. In Thailand, where many students enroll in English or Mandarin programmes and even trilingual international schools, residents have hoped language learning will sharpen thinking and problem-solving to drive the country’s development.
