Episode notes
Bilingualism Helps Health, Not IQ
- Bilingualism doesn't reliably raise IQ though it may delay dementia by a few years.
- John McWhorter says learning languages builds neurons but research doesn't show a general smartness boost.
Shakespeare Needs Modern Adjustments
- Shakespeare's English has shifted so much that modern audiences often can't follow plays without prior study or updates.
- McWhorter argues for updating wording so contemporary audiences can actually understand and enjoy Shakespeare.
Start Language Learning Early
- Teach languages earlier than age 13 if you want fluent speakers, because ability ossifies after early teens.
- Stop imposing unpopular language curricula; focus on practical, motivated learning instead.
